  OCTOBER 18, 1892





This is the story of talking at a distance, of sending messages
through space. It is the story of great men--Morse, Thomson, Bell,
Marconi, and others--and how, with the aid of men like Field, Vail,
Catty, Pupin, the scientist, and others in both the technical and
commercial fields, they succeeded in flashing both messages and speech
around the world, with wires and without wires. It is the story of
how the thought of the world has been linked together by those modern
wonders of science and of industry--the telegraph, the submarine
cable, the telephone, the wireless telegraph, and, most recently, the
wireless telephone.

The story opens with the primitive methods of message-sending by fire
or smoke or other signals. The life and experiments of Morse are then
pictured and the dramatic story of the invention and development of
the telegraph is set forth. The submarine cable followed with the
struggles of Field, the business executive, and Thomson, the inventor
and scientific expert, which finally culminated in success when the
_Great Eastern_ landed a practical cable on the American coast. The
early life of Alexander Graham Bell was full of color, and I have told
the story of his patient investigations of human speech and hearing,
which, finally culminated in a practical telephone. There follows the
fascinating story of Marconi and the wireless telegraph. Last comes
the story of the wireless telephone, that newest wonder which has come
among us so recently that we can scarcely realize that it is here. An
inner view of the marvelous development of the telephone is added in
an appendix.

The part played by the great business leaders who have developed and
extended the new inventions, placing them at the service of all,
has not been forgotten. Not only have means of communication been
discovered, but they have been improved and put to the widest
practical use with remarkable efficiency and celerity. The stories of
these developments, in both the personal and executive sides, embody
the true romance of the modern business world.

The great scientists and engineers who have wrought these wonders
which have had so profound an influence upon the life of the
world lived, and are living, lives filled with patient effort,
discouragement, accomplishment, and real romance. They are interesting
men who have done interesting things. Better still, they have done
important, useful things. This book relates their life stories in a
connected form, for they have all worked for a similar end. The story
of these men, who, starting in early youth in the pursuit of a great
idea, have achieved fame and success and have benefited civilization,
cannot but be inspiring. They did not stumble upon their discoveries
by any lucky accident. They knew what they sought, and they labored
toward the goal with unflagging zeal. Had they been easily discouraged
we might still be dependent upon the semaphore and the pony express
for the transmission of news. But they persevered until success was
attained, and in the account of their struggle to success every one
may find encouragement in facing his own tasks.

One can scarce overestimate the value of modern methods of
communication to the world. So much of our development has been more
or less directly dependent upon it that it is difficult to fancy our
situation without the telegraph and telephone. The diligence with
which the ancients sought speedy methods for the sending of messages
demonstrates the human need for them. The solution of this great
problem, though long delayed, came swiftly, once it was begun.

Even the simple facts regarding "Masters of Space" and their lives of
struggle and accomplishment in sending messages between distant points
form an inspiring story of great achievement.





    Signaling the Fall of Troy--Marine Signaling among the
    Argonauts--Couriers of the Greeks, Romans, and
    Aztecs--Sound-signaling--Stentorophonic Tube--The Shouting
    Sentinels--The Clepsydra--Signal Columns--Indian Fire and Smoke

It was very early in the history of the world that man began to feel
the urgent need of communicating with man at a distance. When village
came into friendly contact with village, when nations began to
form and expand, the necessity of sending intelligence rapidly and
effectively was clearly realized. And yet many centuries passed
without the discovery of an effective system. Those discoveries were
to be reserved for the thinkers of our age.

We can understand the difficulties that beset King Agamemnon as he
stood at the head of his armies before the walls of Troy. Many were
the messages he would want to send to his native kingdom in Greece
during the progress of the siege. Those at home would be eager for
news of the great enterprise. Many contingencies might arise which
would make the need for aid urgent. Certainly Queen Clytemnestra
eagerly awaited word of the fall of the city. Yet the slow progress of
couriers must be depended upon.

One device the king hit upon which was such as any boy might devise
to meet the simplest need. "If I can go skating tonight," says Johnny
Jones to his chum, "I'll put a light in my window." Such is the simple
device which has been used to bear the simplest message for ages. So
King Agamemnon ordered beacon fires laid on the tops of Mount Ida,
Mount Athos, Mount Cithæron, and on intervening eminences. Beside them
he placed watchers who were always to have their faces toward Troy.
When Troy fell a near-by fire was kindled, and beacon after beacon
sprang into flame on the route toward Greece. Thus was the message
of the fall of Troy quickly borne to the waiting queen by this
preconceived arrangement. Yet neither King Agamemnon nor his sagest
counselors could devise an effective system for expediting their

Prearranged signals were used to convey news in even earlier times.
Fire, smoke, and flags were used by the Egyptians and the Assyrians
previous to the Trojan War. The towers along the Chinese Wall were
more than watch-towers; they were signal-towers. A flag or a light
exhibited from tower to tower would quickly convey a certain message
agreed upon in advance. Human thought required a system which could
convey more than one idea, and yet skill in conveying news grew

Perhaps the earliest example of marine signaling of which we know
is recorded of the Argonautic Expedition. Theseus devised the use of
colored sails to convey messages from ship to ship of the fleet, and
caused the death of his father by his failure to handle the signals
properly. Theseus sailed into conflict with the enemy with black sails
set, a signal of battle and of death. With the battle over and himself
the victor, he forgot to lower the black flag and set the red flag of
victory. His father, the aged Ægeus, seeing the black flag, believed
it reported his son's death, and, flinging himself into the sea, was

In time it occurred to the great monarchs as their domains extended
to establish relays of couriers to bear the messages which must be
carried. Such systems were established by the Greeks, the Romans, and
the Aztecs. Each courier would run the length of his own route and
would then shout or pass the message to the next runner, who would
speed it away in turn. Such was the method employed by our own
pony-express riders.

An ancient Persian king thought of having the messages shouted from
sentinel to sentinel, instead of being carried more slowly by relays
of couriers. So he established sentinels at regular intervals within
hearing of one another, and messages were shouted from one to the
other. Just fancy the number of sentinels required to establish a line
between distant cities, and the opportunities for misunderstanding and
mistake! The ancient Gauls also employed this method of communication.
Cæsar records that the news of the massacre of the Romans at Orleans
was sent to Auvergne, a distance of nearly one hundred and fifty
miles, by the same evening.

Though signaling by flashes of light occurred to the ancients, we have
no knowledge that they devised a way of using the light-flashes for
any but the simplest prearranged messages. The mirrors of the Pharaohs
were probably used to flash light for signal purposes. We know that
the Persians applied them to signaling in time of war. It is reported
that flashes from the shields were used to convey news at the battle
of Marathon. These seem to be the forerunners of the heliograph. But
the heliograph using the dot-and-dash system of the Morse code can
be used to transmit any message whatever. The ancients had evolved
systems by which any word could be spelled, but they did not seem to
be able to apply them practically to their primitive heliographs.

An application of sound-signaling was worked out for Alexander
the Great, which was considered one of the scientific wonders of
antiquity. This was called a stentorophonic tube, and seems to have
been a sort of gigantic megaphone or speaking-trumpet. It is recorded
that it sent the voice for a dozen miles. A drawing of this strange
instrument is preserved in the Vatican.

Another queer signaling device, built and operated upon a novel
principle, was an even greater wonder among the early peoples. This
was known as a clepsydra. Fancy a tall glass tube with an opening at
the bottom in which a sort of faucet was fixed. At varying heights
sentences were inscribed about the tube. The tube, being filled with
water, with, a float at the top, all was ready for signaling any
of the messages inscribed on the tube to a station within sight and
similarly equipped. The other station could be located as far away
as a light could be seen. The station desiring to send a message to
another exhibited its light. When the receiving station showed its
light in answer, the tap was opened at the bottom of the tube in each
station. When the float dropped until it was opposite the sentence
which it was desired to transmit, the sending station withdrew its
light and closed the tap. This was a signal for the receiving station
to stop the flow of water from its tube. As the tubes were just alike,
and the water had flowed out during the same period at equal speed,
the float at the receiving station then rested opposite the message to
be conveyed.

Many crude systems of using lights for signaling were employed. Lines
of watch-towers were arranged which served as signal-stations. The
ruins of the old Roman and Gallic towers may still be found In France.
Hannibal erected them in Africa and Spain. Colored tunics and spears
were also used for military signals in the daytime. For instance,
a red tunic displayed meant prepare for battle; while a red spear
conveyed the order to sack and devastate.

An ancient system of camp signals from columns is especially
interesting as showing a development away from the prearranged signals
of limited application. For these camp signals the alphabet was
divided into five or six parts, and a like number of columns erected
at each signal-station. Each column represented one group of letters.
Suppose that we should agree to get along without the Q and the Z
and reduce our own alphabet to twenty-four letters for use in such
a system. With six columns we would then have four letters for each
column. The first column would be used to signal A, B, C, and D. One
light or flag shown from column one would represent A, two flags
or lights B, and so on. Thus any word could be spelled out and any
message sent. Without doubt the system was slow and cumbersome, but it
was a step in the right direction.

The American Indians developed methods of transmitting news which
compare very favorably with the means employed by the ancients.
Smoke-rings and puffs for the daytime, and fire-arrows at night, were
used by them for the sending of messages. Smoke signals are obtained
by building a fire of moist materials. The Indian obtains his
smoke-puffs by placing a blanket or robe over the fire, withdrawing
it for an instant, and then replacing it quickly. In this way puffs of
smoke may be sent aloft as frequently as desired.

A column of smoke-puffs was used as a warning signal, its meaning
being: Look out, the enemy is near. One smoke-puff was a signal for
attention; two puffs indicated that the sender would camp at that
place. Three puffs showed that the sender was in danger, as the enemy
was near.

Fire-arrows shot across the sky at night had a similar meaning. The
head of the arrow was dipped in some highly inflammable substance and
then set on fire at the instant before it was discharged from the bow.
One fire-arrow shot into the sky meant that the enemy were near; two
signaled danger, and three great danger. When the Indian shot many
fire-arrows up in rapid succession he was signaling to his friends
that his enemies were too many for him. Two arrows discharged into the
air at the same time indicated that the party sending them was
about to attack. Three indicated an immediate attack. A fire-arrow
discharged diagonally across the sky indicated the direction in which
the sender would travel. Such were the methods which the Indians used,
working out different meanings for the signals in the various tribes.

Very slight progress was made in message-sending in medieval times,
and it was the middle of the seventeenth century before even signal
systems were attained which were in any sense an improvement. For many
centuries the people of the world existed, devising nothing better
than the primitive methods outlined above.



    Marine and Military Signals--Code Flags--Wig-wag--Semaphore
    Telegraphs--Heliographs--Ardois Signals--Submarine Signals.

In naval affairs some kind of an effective signal system is
imperative. Even in the ordinary evolutions of a fleet the commander
needs some better way of communicating with the ship captains than
despatching a messenger in a small boat. The necessity of quick and
sure signals in time of battle is obvious. Yet for many centuries
naval signals were of the crudest.

The first distinct advance over the primitive methods by which the
commander of one Roman galley communicated with another came with the
introduction of cannon as a naval arm. The use of signal-guns was soon
thought of, and war-ships used their guns for signal purposes as early
as the sixteenth century. Not long after came the square-rigged
ship, and it soon occurred to some one that signals could be made by
dropping a sail from the yard-arm a certain number of times.

Up to the middle of the seventeenth century the possibilities of
the naval signal systems were limited indeed. Only a few prearranged
orders and messages could be conveyed. Unlimited communication at a
distance was still impossible, and there were no means of sending a
message to meet an unforeseen emergency. So cumbersome were the signal
systems in use that even though they would convey the intelligence
desired, the speaking-trumpet or a courier was employed wherever

To the officers of the British navy of the seventeenth century
belongs the credit for the first serious attempt to create a system of
communication which would convey any and all messages. It is not clear
whether Admiral Sir William Penn or James II. established the code.
It was while he was Duke of York and the commander of Britain's
navy, that the James who was later to be king took this part in the
advancement of means of communication. Messages were sent by varying
the position of a single signal flag.

In 1780 Admiral Kempenfeldt thought of adding other signal flags
instead of depending upon the varied positions of a single signal.
From his plan the flag signals now in use by the navies of the world
were developed. The basis of his system was the combining of distinct
flags in pairs.

The work of Admiral Philip Colomb marked another long step forward
in signaling between ships. While a young officer he developed a
night-signal system of flashing lights, still in use to some extent,
and which bears his name. Colomb's most important contribution to the
art of signaling was his realization of the utility of the code which
Morse had developed in connection with the telegraph.

Code flags, which are largely used between ships, have not been
entirely displaced by the wireless. The usual naval code set consists
of a set of alphabet flags and pennants, ten numeral flags, and
additional special flags. This of course provides for spelling out any
conceivable message by simply hoisting letter after letter. So slow
a method is seldom used, however. Various combinations of letters and
figures are used to indicate set terms or sentences set forth in the
code-book. Thus the flags representing A and E, hoisted together, may
be found on reference to the code-book to mean, "Weigh anchor." Each
navy has its own secret code, which is carefully guarded lest it be
discovered by a possible enemy. Naval code-books are bound with metal
covers so that they may be thrown overboard in case a ship is forced
to surrender.

The international code is used by ships of all nations. It is the
universal language of the sea, and by it sailors of different tongues
may communicate through this common medium. Any message may be
conveyed by a very few of the flags in combination.

The wig-wag system, a favorite and familiar method of communication
with every Boy Scout troop, is in use by both army and navy. The
various letters of the alphabet are indicated by the positions in
which the signaler holds his arms. Keeping the arms always forty-five
degrees apart, it is possible to read the signals at a considerable
distance. Navy signalers have become very efficient with this form of
communication, attaining a speed of over fifteen words a minute.

A semaphore is frequently substituted for the wig-wag flags both on
land and on sea. Navy semaphores on big war-ships consist of arms ten
or twelve feet long mounted at the masthead. The semaphore as a means
of communication was extensively used on land commercially as well as
by the army. A regular semaphore telegraph system, working in relays
over considerable distances was in operation in France a century ago.
Other semaphore telegraphs were developed in England.

The introduction of the Morse code and its adaptation to signaling by
sight and sound did much to simplify these means of communication. The
development of signaling after the adoption of the Morse code, though
it occurred subsequent to the introduction of the telegraph, may
properly be spoken of here, since the systems dependent upon sight and
sound grow from origins more primitive than those which depend upon
electricity. Up to the middle of the nineteenth century armies had
made slight progress in perfecting means of communication. The British
army had no regular signal service until after the recommendations
of Colomb proved their worth in naval affairs. The German army, whose
systems of communication have now reached such perfection, did not
establish an army signal service until 1902.

The simplicity of the dot and dash of the Morse code makes it
readily available for almost any form of signaling under all possible
conditions. Two persons within sight of each other, who understand
the code, may establish communication by waving the most conspicuous
object at hand, using a short swing for a dot and a long swing for a
dash. Two different shapes may also be exhibited, one representing a
dot and the other a dash. The dot-and-dash system is also admirably
adapted for night signaling. A search-light beam may be swung across
the sky through short and long arcs, a light may be exhibited and
hidden for short and long periods, and so on. Where the search-light
may be played upon a cloud it may be seen for very considerable
distances, messages having been sent forty miles by this means.
Fog-horns, whistles, etc., may be similarly employed during fogs or
amid thick smoke. A short blast represents a dot, and a long one a

The heliograph, which established communication by means of short and
long light-flashes, is another important means of signaling to which
the Morse code has been applied. This instrument catches the rays of
the sun upon a mirror, and thence casts them to a distant receiving
station. A small key which throws the mirror out of alignment serves
to obscure the flashes for a space at the will of the sender, and so
produces short or long flashes.

The British army has made wide use of the heliograph in India and
Africa. During the British-Boer War It formed the sole means of
communication between besieged garrisons and the relief forces.
Where no mountain ranges intervene and a bright sun is available,
heliographic messages may be read at a distance of one hundred and
fifty miles.

While the British navy used flashing lights for night signals, the
United States and most other navies adopted a system of fixed colored
lights. The system in use in the United States Navy is known as the
Ardois system. In this system the messages are sent by four lights,
usually electric, which are suspended from a mast or yard-arm. The
lights are manipulated by a keyboard situated at a convenient point on
the deck. A red lamp is flashed to indicate a dot in the Morse code,
while a white lamp indicates a dash. The Ardois system is also used by
the Army. The perfection of wireless telegraphy has caused the Ardois
and other signal systems depending upon sight or sound to be discarded
in all but exceptional cases. The wig-wag and similar systems will
probably never be entirely displaced by even such superior systems
as wireless telegraphy. The advantage of the wig-wag lies in the
fact that no apparatus is necessary and communication may thus be
established for short distances almost instantly. Its disadvantages
are lack of speed, impenetrability to dust, smoke, and fog, and the
short ranges over which it may be operated.

There is another form of sound-signaling which, though it has been
developed in recent years, may properly be mentioned in connection
with earlier signal systems of similar nature. This is the submarine
signal. We have noted that much attention was paid to communication by
sound-waves through the medium of the air from the earliest times. It
was not until the closing years of the past century, however, that
the superior possibilities of water as a conveyer of sound were

Arthur J. Mundy, of Boston, happened to be on an American steamer on
the Mississippi River in the vicinity of New Orleans. It was rumored
that a Spanish torpedo-boat had evaded the United States war vessels
and made its way up the great river. The general alarm and the
impossibility of detecting the approach of another vessel set
Mundy thinking. It seemed to him that there should be some way
of communicating through the water and of listening for sounds
underwater. He recalled his boyhood experiments in the old
swimming-hole. He remembered how distinctly the sound of stones
cracked together carried to one whose ears were beneath the surface.
Thus the idea of underwater signaling was born.

Mundy communicated this idea to Elisha Gray, and the two, working
together, evolved a successful submarine signal system. It was on the
last day of the nineteenth century that they were able to put their
experiments into practical working form. Through a well in the center
of the ship they suspended an eight-hundred-pound bell twenty feet
beneath the surface of the sea. A receiving apparatus was located
three miles distant, which consisted simply of an ear-trumpet
connected to a gas-pipe lowered into the sea. The lower end of the
pipe was sealed with a diaphragm of tin. When submerged six feet
beneath the surface the strokes of the bell could be heard. Then
a special electrical receiver of extreme sensitiveness, known as a
microphone, was substituted and connected at the receiving station
with an ordinary telephone receiver. With this receiving apparatus the
strokes of the bell could be heard at a distance of over ten miles.

This system has had a wide practical application for communication
both between ship and ship and between ship and shore. Most
transatlantic ships are now equipped with such a system. The
transmitter consists of a large bell which is actuated either by
compressed air or by an electro-magnetic system. This is so arranged
that it may be suspended over the side of the ship and lowered
well beneath the surface of the water. The receivers consist of
microphones, one on each side of the ship. The telephone receivers
connected to the two microphones are mounted close together on an
instrument board on the bridge of the ship. The two instruments are
used when it is desired to determine the direction from which the
signals come. If the sound is stronger in the 'phone on the right-hand
side of the ship the commander knows that the signals are coming from
that direction. If the signals are from a ship in distress he may
proceed toward it by turning his vessel until the sound of the
signal-bell is equal in the two receivers. The ability to determine
the direction from which the signal comes is especially valuable
in navigating difficult channels in foggy weather. Signal-bells are
located near lighthouses and dangerous reefs. Each calls its own
number, and the vessel's commander may thus avoid obstructions and
guide the ship safely into the harbor. The submarine signal is equally
useful in enabling vessels to avoid collision in fogs. Because water
conducts sound much better than air, submarine signals are far better
than the fog-horn or whistles.

The submarine signal system has also been applied to submarine
war-ships. By this means alone may a submarine communicate with
another, with a vessel on the surface, or with a shore station.

An important and interesting adaptation of the marine signal was made
to meet the submarine warfare of the great European conflict. At first
it seemed that battle-ship and merchantman could find no way to locate
the approach of an enemy submarine. But it was found that by means
of the receiving apparatus of the submarine telephone an approaching
submarine could be heard and located. While the sounds of the
submarine's machinery are not audible above the water, the delicate
microphone located beneath the water can detect them. Hearing a
submarine approaching beneath the surface, the merchantman may avoid
her and the destroyers and patrol-boats may take means to effect her



    From Lodestone to Leyden Jar--The Mysterious "C.M."--Spark and
    Frictional Telegraphs--The Electro-magnet--Davy and the Relay

The thought and effort directed toward improving the means of
communication brought but small results until man discovered and
harnessed for himself a new servant--electricity. The story of
the growth of modern means of communication is the story of the
application of electricity to this particular one of man's needs.
The stories of the Masters of Space are the stories of the men who so
applied electricity that man might communicate with man.

Some manifestations of electricity had been known since long before
the Christian era. A Greek legend relates how a shepherd named Magnes
found that his crook was attracted by a strange rock. Thus was the
lodestone, the natural magnetic iron ore, discovered, and the legend
would lead us to believe that the words magnet and magnetism were
derived from the name of the shepherd who chanced upon this natural
magnet and the strange property of magnetism.

The ability of amber, when rubbed, to attract straws, was also known
to the early peoples. How early this property was found, or how, we do
not know. The name electricity is derived from _elektron_, the Greek
name for amber.

The early Chinese and Persians knew of the lodestone, and of the
magnetic properties of amber after it has been rubbed briskly. The
Romans were familiar with these and other electrical effects. The
Romans had discovered that the lodestone would attract iron, though a
stone wall intervened. They were fond of mounting a bit of iron on a
cork floating in a basin of water and watch it follow the lodestone
held in the hand. It is related that the early magicians used it as a
means of transmitting intelligence. If a needle were placed upon a bit
of cork and the whole floated in a circular vessel with the alphabet
inscribed about the circle, one outside the room could cause the
needle to point toward any desired letters in turn by stepping to the
proper position with the lodestone. Thus a message could be sent to
the magician inside and various feats of magic performed. Our own
modern magicians are reported as availing themselves of the more
modern applications of electricity in somewhat similar fashion and
using small, easily concealed wireless telegraph or telephone sets for
communication with their confederates off the stage.

The idea of encircling a floating needle with the alphabet was
developed into the sympathetic telegraph of the sixteenth century,
which was based on a curious error. It was supposed that needles which
had been touched by the same lodestone were sympathetic, and that if
both were free to move one would imitate the movements of another,
though they were at a distance. Thus, if one needle were attracted
toward one letter after the other, and the second similarly mounted
should follow its movements, a message might readily be spelled out.
Of course the second needle would not follow the movements of the
first, and so the sympathetic telegraph never worked, but much effort
was expended upon it.

In the mean time others had learned that many substances besides
amber, on being rubbed, possessed magnetic properties. Machines by
which electricity could be produced in greater quantities by friction
were produced and something was learned of conductors.

Benjamin Franklin sent aloft his historic kite and found that
electricity came down the silken cord. He demonstrated that frictional
and atmospheric electricity are the same. Franklin and others sent the
electric charge along a wire, but it did not occur to them to endeavor
to apply this to sending messages.

Credit for the first suggestion of an electric telegraph must be given
to an unknown writer of the middle eighteenth century. In the _Scots
Magazine_ for February 17, 1755, there appeared an article signed
simply, "C.M.," which suggested an electric telegraph. The writer's
idea was to lay an insulated wire for each letter of the alphabet.
The wires could be charged from an electrical machine in any desired
order, and at the receiving end would attract disks of paper marked
with the letter which that wire represented, and so any message could
be spelled out. The identity of "C.M." has never been established, but
he was probably Charles Morrison, a Scotch surgeon with a reputation
for electrical experimentation, who later emigrated to Virginia. Of
course "C.M.'s" telegraph was not practical, because of the many wires
required, but it proved to be a fertile suggestion which was followed
by many other thinkers. One experimenter after another added an
improvement or devised a new application.

A French scientist devised a telegraph which it is suspected might
have been practical, but he kept his device secret, and, as Napoleon
refused to consider it, it never was put to a test. An Englishman
devised a frictional telegraph early in the last century and
endeavored to interest the Admiralty. He was told that the semaphore
was all that was required for communication. Another submitted a
similar system to the same authorities in 1816, and was told that
"telegraphs of any kind are now wholly unnecessary." An American
inventor fared no better, for one Harrison Gray Dyar, of New York, was
compelled to abandon his experiments on Long Island and flee because
he was accused of conspiracy to carry on secret communication, which
sounded very like witchcraft to our forefathers. His telegraph sent
signals by having the electric spark transmitted by the wire decompose
nitric acid and so record the signals on moist litmus paper. It seems
altogether probable that had not the discovery of electro-magnetism
offered improved facilities to those seeking a practical telegraph,
this very chemical telegraph might have been put to practical use.

In the early days of the nineteenth century the battery had come into
being, and thus a new source of electric current was available for
the experimenters. Coupled with this important discovery in its
effect upon the development of the telegraph was the discovery of
electro-magnetism. This was the work of Hans Christian Oersted, a
native of Denmark. He first noticed that a current flowing through
a wire would deflect a compass, and thus discovered the magnetic
properties of the electric current. A Frenchman named Ampère,
experimenting further, discovered that when the electric current is
sent through coils of wire the magnetism is increased.

The possibility of using the deflection of a magnetic needle by
an electric current passing through a wire as a means of conveying
intelligence was quickly grasped by those who were striving for
a telegraph. Experiments with spark and chemical telegraphs were
superseded by efforts with this new discovery. Ampère, acting upon the
suggestion of La Place, an eminent mathematician, published a plan for
a feasible telegraph. This was later improved upon by others, and it
was still early in the nineteenth century that a model telegraph was
exhibited in London.

About this time two professors at the University of Göttingen were
experimenting with telegraphy. They established an experimental line
between their laboratories, using at first a battery. Then Faraday
discovered that an electric current could be generated in a wire by
the motion of a magnet, thus laying the basis for the modern dynamo.
Professors Gauss and Weber, who were operating the telegraph line at
Göttingen, adapted this new discovery to their needs. They sent the
message by moving a magnetic key. A current was thus generated in the
line, and, passing over the wire and through a coil at the farther
end, moved a magnet suspended there. The magnet moved to the right or
left, depending on the direction of the current sent through the
wire. A tiny mirror was mounted on the receiving magnet to magnify its
movement and so render it more readily visible.

One Steinheil, of Munich, simplified it and added a call-bell. He
also devised a recording telegraph in which the moving needle at the
receiving station marked down its message in dots and dashes on a
ribbon of paper. He was the first to utilize the earth for the return
circuit, using a single wire for despatching the electric current used
in signaling and allowing it to return through the ground.

In 1837, the same year in which Wheatstone and Morse were busy
perfecting their telegraphs, as we shall see, Edward Davy exhibited a
needle telegraph in London. Davy also realized that the discoveries
of Arago could be used in improving the telegraph and making it
practical. Arago discovered that the current passing through a coil of
wire served to magnetize temporarily a piece of soft iron within it.
It was this principle upon which Morse was working at this time. Davy
did not carry his suggestions into effect, however. He emigrated to
Australia, and the interruption in his experiments left the field open
for those who were finally to bring the telegraph into usable form.
Davy's greatest contribution to telegraphy was the relay system by
which very weak currents could call into play strong currents from
a local battery, and so make the signals apparent at the receiving

    Electric Telegraph Line Installed--The Capture of the "Kwaker"--The
    Automatic Transmitter.

Before we come to the story of Samuel F.B. Morse and the telegraph
which actually proved a commercial success as the first practical
carrier of intelligence which had been created for the service of man,
we should pause to consider the achievements of Charles Wheatstone.
Together with William Fothergill Cooke, another Englishman, he
developed a telegraph line that, while it did not attain commercial
success, was the first working telegraph placed at the service of the

Charles Wheatstone was born near Gloucester in 1802. Having completed
his primary schooling, Charles was apprenticed to his uncle, who was
a maker and seller of musical instruments. He showed little aptitude
either in the workshop or in the store, and much preferred to continue
the study of books. His father eventually took him from his uncle's
charge and allowed him to follow his bent. He translated poetry from
the French at the age of fifteen, and wrote some verse of his own. He
spent all the money he could secure on books. Becoming interested in a
book on Volta's experiments with electricity, he saved up his coppers
until he could purchase it. It was in French, and he found the
technical descriptions rather too difficult for his comprehension, so
that he was forced to save again to buy a French-English dictionary.
With the aid of this he mastered the volume.

Immediately his attention was turned toward the wonders of the infant
science of electricity, and he eagerly endeavored to perform the
experiments described. Aided by his older brother, he set to work on
a battery as a source of current. Running short of funds with which to
purchase copper plates, he again began to save his pennies. Then the
idea occurred to him to use the pennies themselves, and his first
battery was soon complete.

He continued his experiments in various fields until, at the age of
nineteen, he first brought himself to public notice with his enchanted
lyre. This he placed on exhibition in music-shops in London. It
consisted of a small lyre suspended from the ceiling which gave forth,
in turn, the sounds of various musical instruments. Really the lyre
was merely a sounding-box, and the vibrations of the music were
conveyed from instruments, played in the next room, to the lyre
through a steel rod. The young man spent much time experimenting with
the transmission of sound. Having conveyed music through the steel rod
to his enchanted lyre, much to the mystification of the Londoners,
he proposed to transmit sounds over a considerable distance by this
method. He estimated that sound could be sent through steel rods at
the rate of two hundred miles a second and suggested the use of such
a rod as a telegraph between London and Edinburgh. He called his
arrangement a telephone.

A scientific writer of the day, commenting in a scientific journal
on the enchanted lyre which Wheatstone had devised, suggested that it
might be used to render musical concerts audible at a distance. Thus
an opera performed in a theater might be conveyed through rods to
other buildings in the vicinity and there reproduced. This was never
accomplished, and it remained for our own times to accomplish this and
even greater wonders.

Wheatstone also devised an instrument for increasing feeble sound,
which he called a microphone. This consisted of a pair of rods to
convey the sound vibrations to the ears, and does not at all resemble
the modern electrical microphone. Other inventions in the transmission
and reproduction of sound followed, and he devoted no little attention
to the construction of improved musical instruments. He even made some
efforts to produce a practical talking-machine, and was convinced
that one would be attained. At thirty-two he was widely famed as a
scientist and had been made a professor of experimental physics
in King's College, London. His most notable work at this time was
measuring the speed of the electric current, which up to that time had
been supposed to be instantaneous.

By 1835 Wheatstone had abandoned his plans for transmitting sounds
through long rods of metal and was studying the telegraph. He
experimented with instruments of his own and proposed a line across
the Thames. It was in 1836 that Mr. Cooke, an army officer home on
leave, became interested in the telegraph and devoted himself to
putting it on a working basis. He had already exhibited a crude set
when he came to Wheatstone, realizing his own lack of scientific
knowledge. The two men finally entered into partnership, Wheatstone
contributing the scientific and Cooke the business ability to the new
enterprise. The partnership was arranged late in 1837, and a patent
taken out on Wheatstone's five-needle telegraph.

In this telegraph a magnetic needle was located within a loop formed
by the telegraph circuit at the receiving end. When the circuit was
closed the needle was deflected to one side or the other, according to
the direction of the current. Five separate circuits and needles were
used, and a variety of signals could thus be sent. Five wires, with a
sixth return wire, were used in the first experimental line erected in
London in 1837. So in the year when Morse was constructing his models
Wheatstone and Cooke were operating an experimental line, crude
and impracticable though it was, and enjoying the sensations of
communicating with each other at a distance.

In 1841 the telegraph was placed on public exhibition at so much a
head, but it was viewed as an entertaining novelty without utility by
the public at large. After many disappointments the inventors secured
the cooperation of the Great Western Railroad, and a line was erected
for a distance of thirteen miles. But the public would not patronise
the line until its utility was strikingly demonstrated by the capture
of the "Kwaker."

Early one morning a woman was found dead in her home in the suburbs of
London. A man had been observed leaving the house, and his appearance
had been noted. Inquiries revealed that a man answering his
description had left on the slow train for London. Without the
telegraph he could not have been apprehended. But the telegraph was
available at this point, and his description was telegraphed ahead and
the police in London were instructed to arrest him upon his arrival.
"He is dressed as a Quaker," ran the message. There was no Q in the
alphabet of-the five-needle instrument, and so the sender spelled
Quaker, Kwaker. The clerk at the receiving end could not-understand
the strange word, and asked to have it repeated again and again.
Finally some one suggested that the message be completed and the whole
was then deciphered. When the man dressed as a Quaker stepped from the
slow train on his arrival at London the police were awaiting him; he
was arrested and eventually confessed the murder. The news of this
capture and the part the telegraph played gave striking proof of the
utility of the new invention, and public skepticism and indifference
were overcome.

By 1845 Wheatstone had so improved his apparatus that but one wire was
required. The single-needle instrument pointed out the letters on the
dial around it by successive deflections in which it was arranged
to move, step by step, at the will of the sending station. The
single-needle instrument, though generally displaced by Morse's
telegraph, remained in use for a long time on some English lines.
Wheatstone had also invented a type-printing telegraph, which he
patented in 1841. This required two circuits.

With a working telegraph attained, the partners became involved in an
altercation as to which deserved the honor of inventing the same.
The quarrel was finally submitted to two famous scientists for
arbitration. They reported that the telegraph was the result of
their joint labors. To Wheatstone belongs the credit for devising
the apparatus; to Cooke for introducing it and placing it before the
public in working form. Here we see the combination of the man of
science and the man of business, each contributing needed talents for
the establishment of a great invention on a working basis.

Wheatstone's researches in the field of electricity were constant.
In 1840 he devised a magnetic clock and proposed a plan by which many
clocks, located at different points, could be set at regular intervals
with the aid of electricity. Such a system was the forerunner of
the electrically wound and regulated clocks with which we are now so
familiar. He also devised a method for measuring the resistance which
wires offer to the passage of an electric current. This is known
as Wheatstone's bridge and is still in use in every electrical and
physical laboratory. He also invented a sound telegraph by which
signals were transmitted by the strokes of a bell operated by the
current at the receiving end of the circuit.

The invention of Wheatstone's which proved to be of greatest lasting
importance in connection with the telegraph was the automatic
transmitter. By this system the message is first punched in a strip of
paper which, when passed through the sending instrument, transmits the
message. By this means he was able to send messages at the rate of one
hundred words a minute. This automatic transmitter is much used for
press telegrams where duplicate messages are to be sent to various

The automatic transmitter brought knighthood to its inventor,
Wheatstone receiving this honor in 1868. Wheatstone took an active
part in the development of the telegraph and the submarine cable up to
the time of his death in 1875.

Wheatstone's telegraph would have served the purposes of humanity
and probably have been universally adopted, had not a better one been
invented almost before it was established. And it is because Morse,
taking up the work where others had left off, was able to invent an
instrument which so fully satisfied the requirements of man for so
long a period that he is known to all of us as the inventor of the
telegraph. And yet, without belittling the part played by Morse,
we must recognize the important work accomplished by Sir Charles

    Paintings--Beginnings of His Invention--The First Instrument--The
    Morse Code--The First Written Message.

When we consider the youth and immaturity of America in the first half
of the nineteenth century, it seems the more remarkable that the honor
of making the first great practical application of electricity should
have been reserved for an American. With the exception of the isolated
work of Franklin, the development of the new science of electrical
learning was the work of Europeans. This was natural, for it was
Europe which was possessed of the accumulated wealth and learning
which are usually attained only by older civilizations. Yet, with all
these advantages, electricity remained largely a scientific plaything.
It was an American who fully recognized the possibilities of this
new force as a servant of man, and who was possessed of the practical
genius and the business ability to devise and introduce a thoroughly
workable system of rapid and certain communication.

We have seen that Wheatstone was early trained as a musician. Samuel
Morse began life as an artist. But while Wheatstone early indicated
his lack of interest in music and devoted himself to scientific
studies while yet a youth, Morse's artistic career was of his own
choosing, and he devoted himself to it for many years. This explains
the fact that Wheatstone attained much scientific success before
Morse, though he was eleven years his junior.

It was in 1791 that Samuel Morse was born. Samuel Finley Breese Morse
was the entire name with which he was endowed by his parents. He came
from the sturdiest of Puritan stock, his father being of English and
his mother of Scotch descent. His father was an eminent divine, and
also notable as a geographer, being the author of the first American
geography of importance. His mother also was possessed of unusual
talent and force. It is interesting to note that Samuel Morse first
saw the light in Charlestown, Massachusetts, at the foot of Breed's
Hill, but little more than a mile from the birthplace of Benjamin
Franklin. He came into the world about a year after Franklin died.
It is interesting to believe that some of the practical talent of
America's first great electrician in some way descended to Samuel

He received an unusual education. At the age of seven he was sent to a
school at Andover, Massachusetts, to prepare him for Phillips Academy.
At the academy he was prepared for Yale College, which he entered when
fifteen years of age. With the knowledge of science so small at the
time, collegiate instruction in such subjects was naturally meager in
the extreme. Jeremiah Day was then professor of natural philosophy at
Yale, and was probably America's ablest teacher of the subject.
His lectures upon electricity and the experiments with which he
illustrated them aroused the interest of Morse, as we learn from the
letters he wrote to his parents at this time.

One principle in particular impressed Morse. This was that "if the
electric circuit be interrupted at any place the fluid will become
visible, and when it passes it will leave an impression upon any
intermediate body." Thus was it stated in the text-book in use at Yale
at that time. More than a score of years after the telegraph had been
achieved Morse wrote:

    The fact that the presence of electricity can be made visible
    in any desired part of the circuit was the crude seed which
    took root in my mind, and grew into form, and ripened into the
    invention of the telegraph.

We shall later hear of the occasion which recalled this bit of
information to Morse's mind.

But though Yale College was at that time a center of scientific
activity, and Morse showed more than a little interest in electricity
and chemistry, his major interest remained art. He eagerly looked
forward to graduation that he might devote his entire time to the
study of painting. It is significant of the tolerance and breadth of
vision of his parents that they apparently put no bars in the path
of this ambition, though they had sacrificed to give him the best
of collegiate trainings that he might fit himself for the ministry,
medicine, or the law. As a boy of fifteen Samuel Morse had painted
water-colors that attracted attention, and he was possessed of enough
talent to paint miniatures while at Yale which were salable at five
dollars apiece, and so aided in defraying his college expenses.

After his graduation from Yale in 1810, Morse devoted himself entirely
to the study of art, still being dependent upon his parents for
support. He secured the friendship and became the pupil of Washington
Allston, then a foremost American painter. In the summer of 1811
Allston sailed for England, and Morse accompanied him. In London he
came to the attention of Benjamin West, then at the height of his
career, and benefited by his advice and encouragement.

That he had no ambition other than his art at this period we may learn
from a letter he wrote to his mother in 1812.

    My passion for my art [he wrote] is so firmly rooted that I
    am confident no human power could destroy it. The more I study
    the greater I think is its claim to the appellation divine. I
    am now going to begin a picture of the death of Hercules, the
    figure to be large as life.

When he had completed this picture to his own satisfaction, he showed
it to West. "Go on and finish it," was West's comment. "But it is
finished," said Morse. "No, no. See here, and here, and here are
places you can improve it." Morse went to work upon his painting
again, only to meet the same comment when he again showed it to West.
This happened again and again. When the youth had finally brought it
to a point where West was convinced it was the very best Morse could
do he had learned a lesson in thoroughness and painstaking attention
to detail that he never forgot.

That he might have a model for his painting Morse had molded a figure
of Hercules in clay. At the advice of West he entered the cast in a
competition for a prize in sculpture, with the result that he received
the prize and a gold medal for his work. He then plunged into the
competition for a prize and medal offered by the Royal Academy for the
best historical painting. His subject was, "The Judgment of Jupiter
in the Case of Apollo, Marpessa, and Idas." Though he completed the
picture to the satisfaction of West, Morse was not able to remain in
London and enter it in the competition. The rules required that the
artist be present in person if he was to receive the prize, but Morse
was forced to return to America. He had been in England for four
years--a year longer than had originally been planned for him--and he
was out of funds, and his parents could support him no longer.

Morse lived in London during the War of 1812, but seems to have
suffered no annoyance other than that of poverty, which the war
intensified by raising the prices of food as well as his necessary
artist's materials to an almost prohibitive figure. The last of the
Napoleonic wars was also in progress. News of the battle of Waterloo
reached London but a short time before Morse sailed for America. It
required two days for the news to reach the English capital. The young
American, whose inability to sell his paintings was driving him from
London, was destined to devise a system which would have carried the
great news to its destination within a few seconds.

But while he gained fame in America and secured praise and attention
as he had in London, he found art no more profitable. He contrived to
eke out an existence by painting an occasional portrait, going from
town to town in New England for this purpose. He turned from art
to invention for a time, joining with his brother in devising a
fire-engine pump of an improved pattern. They secured a patent upon
it, but could not sell it. He turned again to the life of a wandering
painter of portraits. In 1818 he went to Charleston, South Carolina,
at the invitation of his uncle. His portraits proved very popular and
he was soon occupied with work at good prices. This prosperity enabled
him to take unto himself a wife, and the same year he married Lucretia
Walker, of Concord, New Hampshire.

After four years in the South Morse returned to the North, hoping that
larger opportunities would now be ready for him. The result was again
failure. He devoted his time to huge historical paintings, and the
public would neither buy them nor pay to see them when they were
exhibited. Another blow fell upon him in 1825 when his wife died. At
last he began to secure more sitters for his portraits, though his
larger works still failed. He assisted in the organization of the
National Academy of Design and became its first president. In 1829 he
again sailed for Europe to spend three years in study in the galleries
of Paris and Rome. Still he failed to attain any real success in his
chosen work. He had made many friends and done much worthy work, yet
there is little probability that he would have attained lasting fame
as an artist even though his energies had not been turned to other

It was on the packet ship _Sully_, crossing the Atlantic from France,
that Morse conceived the telegraph which was to prove the first great
practical application of electricity. One noon as the passengers
were gathered about the luncheon-table, a Dr. Charles T. Jackson,
of Boston, exhibited an electro-magnet he had secured in Europe, and
described certain electrical experiments he had seen while in Paris.
He was asked concerning the speed of electricity through a wire, and
replied that, according to Faraday, it was practically instantaneous.
The discussion recalled to Morse his own collegiate studies in
electricity, and he remarked that if the circuit were interrupted the
current became visible, and that it occurred to him that these flashes
might be used as a means of communication. The idea of using the
current to carry messages became fixed in his mind, and he pondered,
over it during the remaining weeks of the long, slow voyage.

Doctor Jackson claimed, after Morse had perfected and established his
telegraph, that the idea had been his own, and that Morse had secured
it from him on board the _Sully_. But Doctor Jackson was not a
practical man who either could or did put any ideas he may have had
to practical use. At the most he seems to have simply started Morse's
mind along a new train of thought. The idea of using the current as
a carrier of messages, though it was new to Morse, had occurred to
others earlier, as we have seen. But at the very outset Morse set
himself to find a means by which he might make the current not only
signal the message, but actually record it. Before he landed from the
_Sully_ he had worked out sketches of a printing telegraph. In this
the current actuated an electro-magnet on the end of which was a rod.
This rod was to mark down dots and dashes on a moving tape of paper.

Thus was the idea born. Of course the telegraph was still far from an
accomplished fact. Without the improved electro-magnets and the relay
of Professor Henry, Morse had not yet even the basic ideas upon
which a telegraph to operate over considerable distances could
be constructed. But Morse was possessed of Yankee imagination and
practical ability. He was possessed of a fair technical education
for that day, and he eagerly set himself to attaining the means to
accomplish his end. That he realized just what he sought is shown by
his remark to the captain of the _Sully_ when he landed at New York.
"Well, Captain," he remarked, "should you hear of the telegraph one of
these days as the wonder of the world, remember that the discovery was
made on board the good ship _Sully_."

With the notion of using an electro-magnet as a receiver, an alphabet
consisting of dots and dashes, and a complete faith in the practical
possibilities of the whole, Morse went to work in deadly earnest. But
poverty still beset him and it was necessary for him to devote most of
his time to his paintings, that he might have food, shelter, and the
means to buy materials with which to experiment. From 1832 to 1835 he
was able to make but small progress. In the latter year he secured an
appointment as professor of the literature of the arts of design in
the newly established University of the City of New York. He soon had
his crude apparatus set up in a room at the college and in 1835 was
able to transmit messages. He now had a little more leisure and a
little more money, but his opportunities were still far from what
he would have desired. The principal aid which came to him at the
university was from Professor Gale, a teacher of chemistry. Gale
became greatly interested in Morse's apparatus, and was able to give
him much practical assistance, becoming a partner in the enterprise.
Morse knew little of the work of other experimenters in the field of
electricity and Gale was able to tell Morse what had been learned by
others. Particularly he brought to Morse's attention the discoveries
of another American, Prof. Joseph Henry.

The electro-magnet which actuated the receiving instrument in the
crude set in use by Morse in 1835 had but a few turns of thick
wire. Professor Henry, by his experiments five years earlier, had
demonstrated that many turns of small wire made the electro-magnet far
more sensitive. Morse made this improvement in his own apparatus. In
1832 Henry had devised a telegraph very similar to that of Morse by
which he signaled through a mile of wire. His receiving apparatus
was an electro-magnet, the armature of which struck a bell. Thus the
messages were read by sound, instead of being recorded on a moving
strip of paper as by Morse's system. While Henry was possibly the
ablest of American electricians at that time, he devoted himself
entirely to science and made no effort to put his devices to practical
use. Neither did he endeavor to profit by his inventions, for he
secured no patents upon them.

Professor Henry realized, in common with Morse and others, that if
the current were to be conducted over long wires for considerable
distances it would become so weak that it would not operate a
receiver. Henry avoided this difficulty by the invention of what is
known as the relay. At a distance where the current has become
weak because of the resistance of the wire and losses due to faulty
insulation, it will still operate a delicate electro-magnet with a
very light armature so arranged as to open and close a local circuit
provided with suitable batteries. Thus the recording instrument may
be placed on the local circuit and as the local circuit an opened and
closed in unison with the main circuit, the receiver can be operated.
It was the relay which made it possible to extend telegraph lines to
a considerable distance. It is not altogether clear whether Morse
adopted Henry's relay or devised it for himself. It is believed,
however, that Professor Henry explained the relay to Professor Gale,
who in turn placed it before his partner, Morse.

By 1837 Morse had completed a model, had improved his apparatus, had
secured stronger batteries and longer wires, and mastered the use
of the relay. It was in this year that the House of Representatives
ordered the Secretary of the Treasury to investigate the feasibility
of establishing a system of telegraphs. This action urged Morse to
complete his apparatus and place it before the Government. He was
still handicapped by lack of money, lack of scientific knowledge, and
the difficulty of securing necessary materials and devices. To-day the
experimenter may buy wire, springs, insulators, batteries, and almost
anything that might be useful. Morse, with scanty funds and limited
time, had to search for his materials and puzzle out the way to make
each part for himself with such crude tools as he had available. Need
we wonder that his progress was slow? Instead we should wonder that,
despite all discouragements and handicaps, he clung to his great idea
and labored on.

But assistance was to come to him in this same eventful year of 1837,
and that quite unexpectedly. On a Saturday in September a young man
named Alfred Vail wandered into Professor Gale's laboratory. Morse
was there engaged in exhibiting his model to an English professor then
visiting in New York. The youth was deeply impressed with what he saw.
He realized that here were possibilities of an instrument that would
be of untold service to mankind. Asking Professor Morse whether he
intended to experiment with a longer line, he was informed that such
was his intention as soon as he could secure the means. Young Vail
replied that he thought he could secure the money if Morse would admit
him as a partner. To this Morse assented.

Vail plunged into the enterprise with all the enthusiasm of youth.
That very evening he studied over the commercial possibilities, and
before he retired had marked out on the maps in his atlas the routes
for the most needed lines of communication. The young man applied to
his father for support. The senior Vail was the head of the Speedwell
Iron Works at Morristown, New Jersey, and was a man of unusual
enterprise and ability. He determined to back his son in the
enterprise, and Morse was invited to come and exhibit his model. Two
thousand dollars was needed to make the necessary instruments and
secure the patents. On September 23, 1837, the agreement was drawn
up by the terms of which Alfred Vail was, at his own expense, to
construct apparatus suitable for exhibition to Congress and to secure
a patent. In return he was to receive a one-fourth interest. Very
shortly afterward they filed a caveat in the Patent Office, which is a
notice serving to protect an impending invention.

Alfred Vail immediately set to work on the apparatus, his only helper
being a fifteen-year-old apprentice boy named William Baxter. The
two worked early and late for many months in a secret room in the
iron-works, being forced to fashion every part for themselves. The
first machine was a copy of Morse's model, but Vail's native
ability as a mechanic and his own ingenuity enabled him to make many
improvements. The pencil fastened to the armature which had marked
zigzag lines on the moving paper was replaced by a fountain-pen which
inscribed long and short lines, and thus the dashes and dots of the
Morse code were put into their present form. Morse had worked out an
elaborate telegraphic code or dictionary, but a simpler code by which
combinations of dots and dashes were used to represent letters instead
of numbers in a code was now devised. Vail recognized the importance
of having the simplest combinations of dots and dashes stand for the
most used letters, as this would increase the speed of sending. He
began to figure out for himself the frequency with which the various
letters occur in the English language. Then he thought of the
combination of types in a type-case, and, going to a local newspaper
office, found the result all worked out for him. In each case of type
such common letters as _e_ and _t_ have many more types than little
used letters such as _q_ and _z_. By observing the number of types of
each letter provided, Vail was enabled to arrange them in the order of
their importance in assigning them symbols in the code. Thus the
Morse code was arranged as it stands to-day. Alfred Vail played a
very important part in the arrangement of the code as well as in the
construction of the apparatus, and there are many who believe that the
code should have been called the Vail code instead of the Morse code.


A pen was attached to the pendulum and drawn across the strip of paper
by the action of the electro-magnet. The lead type shown in the lower
right-hand corner was used in making electrical contact when sending a
message. The modern instrument shown in the lower left-hand corner is
the one that sent a message around the world in 1896.]

Morse came down to Speedwell when he could to assist Vail with the
work, and yet it progressed slowly. But at last, early in January
of 1838 they had the telegraph at work, and William Baxter, the
apprentice boy, was sent to call the senior Vail. Within a few moments
he was in the work-room studying the apparatus. Alfred Vail was at
the sending key, and Morse was at the receiver. The father wrote on a
piece of paper these words: "A patient waiter is no loser." Handing it
to his son, he stated that if he could transmit the message to Morse
by the telegraph he would be convinced. The message was sent and
recorded and instantly read by Morse. The first test had been
completed successfully.



    Congress Becomes Interested--Washington to Baltimore Line
    Proposed--Failure to Secure Foreign Patents--Later Indifference of
    Congress--Lean Years--Success at Last--The Line is Built--The First
    Public Message--Popularity.

Morse and his associates now had a telegraph which they were confident
would prove a genuine success. But the great work of introducing this
new wonder to the public, of overcoming indifference and skepticism,
of securing financial support sufficient to erect a real line, still
remained to be done. We shall see that this burden remained very
largely upon Morse himself. Had Morse not been a forceful and able man
of affairs as well as an inventor, the introduction of the telegraph
might have been even longer delayed.

The new telegraph was exhibited in New York and Philadelphia without
arousing popular appreciation. It was viewed as a scientific toy; few
saw in it practical possibilities. Morse then took it to Washington
and set up his instruments in the room of the Committee on Commerce
of the House of Representatives in the Capitol. Here, as in earlier
exhibitions, a majority of those who saw the apparatus in operation
remained unconvinced of its ability to serve mankind. But Morse
finally made a convert of the Hon. Francis O.J. Smith, chairman of
the Committee on Commerce. Smith had previously been in correspondence
with the inventor, and Morse had explained to him at length his belief
that the Government should own the telegraph and control and operate
it for the public good. He believed that the Government should be
sufficiently interested to provide funds for an experimental line a
hundred miles long. In return he was willing to promise the Government
the first rights to purchase the invention at a reasonable price.
Later he changed his request to a line of fifty miles, and estimated
the cost of erection at $26,000.

Smith aided in educating the other members of his committee, and one
day in February of 1838 he secured the attendance of the entire body
at a test of the telegraph over ten miles of wire. The demonstration
convinced them, and many were their expressions of wonder and
amazement. One member remarked, "Time and space are now annihilated."
As a result the committee reported a bill appropriating $30,000 for
the erection of an experimental line between Washington and Baltimore.
Smith's report was most enthusiastic in his praise of the invention.
In fact, the Congressman became so much interested that he sought a
share in the enterprise, and, securing it, resigned from Congress that
he might devote his efforts to securing the passage of the bill and to
acting as legal adviser. At this time the enterprise was divided into
sixteen shares: Morse held nine; Smith, four; Alfred Vail, two; and
Professor Gale, one. We see that Morse was a good enough business man
to retain the control.

Wheatstone and others were developing their telegraphs in Europe, and
Morse felt that it was high time to endeavor to secure foreign patents
on his invention. Accompanied by Smith, he sailed for England in May,
taking with him a new instrument provided by Vail. Arriving in London,
they made application for a patent. They were opposed by Wheatstone
and his associates, and could not secure even a hearing from the
patent authorities. Morse strenuously insisted that his telegraph was
radically different from Wheatstone's, laying especial emphasis on the
fact that his recording instrument printed the message in permanent
form, while Wheatstone's did not. Morse always placed great emphasis
on the recording features of his apparatus, yet these features were
destined to be discarded in America when his telegraph at last came
into use.

With no recourse open to him but an appeal to Parliament, a long and
expensive proceeding with little apparent possibility of success,
Morse went to France, hoping for a more favorable reception. He found
the French cordial and appreciative. French experts watched his tests
and examined his apparatus, pronouncing his telegraph the best of all
that had been devised. He received a patent, only to learn that to be
effective the invention must be put in operation in France within two
years, under the French patent law. Morse sought to establish his line
in connection with a railway, as Wheatstone had established his
in England, but was told that the telegraph must be a Government
monopoly, and that no private parties could construct or operate.
The Government would not act, and Morse found himself again defeated.
Faring no better with other European governments, Morse decided
to return to America to push the bill for an appropriation before

While Morse was in Europe gaining publicity for the telegraph, but
no patents, his former fellow-passenger on the _Sully_, Dr. Charles
Jackson, had laid claim to a share in the invention. He insisted that
the idea had been his and that he had given it to Morse on the trip
across the Atlantic. This Morse indignantly denied.

Congress would now take no action upon the invention. A heated
political campaign was in progress, and no interest could be aroused
in an invention, no matter what were its possibilities in the
advancement of the work and development of the nation. Smith was
in politics, the Vails were suffering from a financial depression,
Professor Gale was a man of very limited means, and so Morse found
himself without funds or support. In Paris he had met M. Daguerre, who
had just discovered photography. Morse had learned the process and,
in connection with Doctor Draper, he fitted up a studio on the roof
of the university. Here they took the first daguerreotypes made in

Morse's work in art had been so much interrupted that he had but few
pupils. The fees that these brought to him were small and irregular,
and he was brought to the very verge of starvation. We are told of the
call Morse made upon one pupil whose tuition was overdue because of a
delay in the arrival of funds from his home.

"Well, my boy," said the professor, "how are we off for money?"

The student explained the situation, adding that he hoped to have the
money the following week.

"Next week!" exclaimed Morse. "I shall be dead by next week--dead of

"Would ten dollars be of any service?" asked the student, astonished
and distressed.

"Ten dollars would save my life," was Morse's reply.

The student paid the money--all he had--and they dined together, Morse
remarking that it was his first meal for twenty-four hours.

Morse's situation and feelings at this time are also illustrated by a
letter he wrote to Smith late in 1841.

    I find myself [he wrote] without sympathy or help from any
    who are associated with me, whose interests, one would think,
    would impell them to at least inquire if they could render me
    some assistance. For nearly two years past I have devoted all
    my time and scanty means, living on a mere pittance, denying
    myself all pleasures and even necessary food, that I might
    have a sum, to put my telegraph into such a position before
    Congress as to insure success to the common enterprise. I
    am crushed for want of means, and means of so trifling a
    character, too, that they who know how to ask (which I do not)
    could obtain in a few hours.... As it is, although everything
    is favorable, although I have no competition and no
    opposition--on the contrary, although every member of
    Congress, so far as I can learn, is favorable--yet I fear all
    will fail because I am too poor to risk the trifling expense
    which my journey and residence in Washington will occasion me.
    I will not run in debt, if I lose the whole matter. No one can
    tell the days and months of anxiety and labor I have had in
    perfecting my telegraphic apparatus. For want of means I have
    been compelled to make with my own hands (and to labor for
    weeks) a piece of mechanism which could be made much better,
    and in a tenth the time, by a good mechanician, thus
    wasting time--time which I cannot recall and which seems
    double-winged to me.

    "Hope deferred maketh the heart sick." It is true, and I have
    known the full meaning of it. Nothing but the consciousness
    that I have an invention which is to mark an era in human
    civilization, and which is to contribute to the happiness of
    millions, would have sustained me through so many and such
    lengthened trials of patience in perfecting it.

A patent on the telegraph had been issued to Morse in 1840. The
issuance had been delayed at Morse's request, as he desired to first
secure foreign patents, his own American rights being protected by the
caveat he had filed. Although the commercial possibilities, and hence
the money value of the telegraph had not been established, Morse was
already troubled with the rival claims of those who sought to secure a
share in his invention.

While working and waiting and saving, Morse conceived the idea of
laying telegraph wires beneath the water. He prepared a wire by
wrapping it in hemp soaked in tar, and then covering the whole with
rubber. Choosing a moonlight night in the fall of 1842, he submerged
his cable in New York Harbor between Castle Garden and Governors
Island. A few signals were transmitted and then the wire was carried
away by a dragging anchor. Truly, misfortune seemed to dog Morse's
footsteps. This seems to have been the first submarine cable, and
in writing of it not long after Morse hazarded the then astonishing
prediction that Europe and America would be linked by telegraphic

Failing to secure effective aid from his associates, Morse hung on
grimly, fighting alone, and putting all of his strength and energy
into the task of establishing an experimental line. It was during
these years that he demonstrated his greatness to the full. His
letters to the members of the Congressional Committee on Commerce show
marked ability. They outline the practical possibilities very clearly.
Morse realized not only the financial possibilities of his invention,
but its benefit to humanity as well. He also presented very practical
estimates of the cost of establishing the line under consideration.
The committee again recommended that $30,000 be appropriated for the
construction of a Washington-Baltimore line. The politicians had come
to look upon Morse as a crank, and it was extremely difficult for his
adherents to secure favorable action in the House. Many a Congressman
compared Morse and his experiments to mesmerism and similar "isms,"
and insisted that if the Government gave funds for this experiment
it would be called upon to supply funds for senseless trials of weird
schemes. The bill finally passed the House by the narrow margin of six
votes, the vote being taken orally because so many Congressmen feared
to go on record as favoring an appropriation for such a purpose.

The bill had still to pass the Senate, and here there seemed little
hope. Morse, who had come to Washington to press his plan, anxiously
waited in the galleries. The bill came up for consideration late one
evening just before the adjournment. A Senator who noticed Morse went
up to him and said:

"There is no use in your staying here. The Senate is not in sympathy
with your project. I advise you to give it up, return home, and think
no more about it."

The inventor went back to his room, with how heavy a heart we may
well imagine. He paid his board bill, and found himself with but
thirty-seven cents in the world. After many moments of earnest prayer
he retired.

Early next morning there came to him Miss Annie Ellsworth, daughter of
his friend the Commissioner of Patents, and said, "Professor, I have
come to congratulate you."

"Congratulate me!" replied Morse. "On what?"

"Why," she exclaimed, "on the passage of your bill by the Senate!"

The bill had been passed without debate in the closing moments of the
session. As Morse afterward stated, this was the turning-point in the
history of the telegraph. His resources were reduced to the minimum,
and there was little likelihood that he would have again been able to
bring the matter to the attention of Congress.

So pleased was Morse over the news of the appropriation, and so
grateful to Miss Ellsworth for her interest in bringing him the good
news, that he promised her that she should send the first message
when the line was complete. With the Government appropriation at his
disposal, Morse immediately set to work upon the Washington-Baltimore
line. Professors Gale and Fisher served as his assistants, and Mr.
Vail was in direct charge of the construction work. Another person
active in the enterprise was Ezra Cornell, who was later to found
Cornell University. Cornell had invented a machine for laying wires
underground in a pipe.

It was originally planned to place the wires underground, as this was
thought necessary or their protection. After running the line some
five miles out from Baltimore it was found that this method of
installing the line was to be a failure. The insulation was not
adequate, and the line could not be operated to the first relay
station. A large portion of the $30,000 voted by Congress had been
spent and the line was still far from completion. Disaster seemed
imminent. Smith lost all faith in the enterprise, demanded most of the
remaining money under a contract he had taken to lay the line, and a
quarrel broke out between him and Morse which further jeopardized the

Morse and such of his lieutenants as remained faithful in this hour of
trial, after a long consultation, decided to string the wire on
poles. The method of attaching the wire to the poles was yet to be
determined. They finally decided to simply bore a hole through each
pole near the top and push the wire through it. Stringing the wire in
such fashion was no small task, but it was finally accomplished. It
was later found necessary to insulate the wire with bottle necks where
it passed through the poles. On May 23, 1844, the line was complete.
Remembering his promise to Miss Ellsworth, Morse called upon her
next morning to give him the first message. She chose, "What hath
God wrought?" and early on the morning of the 24th Morse sat at the
transmitter in the Supreme Court room in the Capitol and telegraphed
these immortal words to Vail at Baltimore. The message was received
without difficulty and repeated back to Morse at Washington. The
magnetic telegraph was a reality.

Still the general public remained unconvinced. As in the case of
Wheatstone's needle telegraph a dramatic incident was needed to
demonstrate the utility of this new servant. Fortunately for Morse,
the telegraph's opportunity came quickly. The Democratic national
convention was in session at Baltimore. After an exciting struggle
they dropped Van Buren, then President, and nominated James K. Polk.
Silas Wright was named for the Vice-Presidency. At that time Mr.
Wright was in Washington. Hearing of the nomination, Alfred Vail
telegraphed it to Morse in Washington. Morse communicated with Wright,
who stated that he could not accept the honor. The telegraph was ready
to carry his message declining the nomination, and within a very few
minutes Vail had presented it to the convention at Baltimore, to the
intense surprise of the delegates there assembled. They refused to
believe that Wright had been communicated with, and sent a committee
to Washington to see Wright and make inquiries. They found that
the message was genuine, and the utility of the telegraph had been
strikingly established.

    Continent--The Improvements of Alfred Vail--Honors Awarded to

For some time the telegraph line between Washington and Baltimore
remained on exhibition as a curiosity, no charge being made for
demonstrating it. Congress made an appropriation to keep the line in
operation, Vail acting as operator at the Washington end. On April
1, 1845, the line was put in operation on a commercial basis,
service being offered to the public at the rate of one cent for four
characters. It was operated as a branch of the Post-office Department.
On the 4th of April a visitor from Virginia came into the Washington
office wishing to see a demonstration. Up to this time not a paid
message had been sent. The visitor, having no permit from the
Postmaster-General, was told that he could only see the telegraph in
operation by sending a message. One cent being all the money he had
other than twenty-dollar bills, he asked for one cent's worth. The
Washington operator asked of Baltimore, "What time is it?" which in
the code required but one character. The reply came, "One o'clock,"
another single character. Thus but two characters had been used, or
one-half cent's worth of telegraphy. The visitor expressed himself as
satisfied, and waived the "change." This penny was the line's first

Under the terms of the agreement by which Congress had made the
appropriation for the experimental line, Morse was bound to give the
Government the first right to purchase his invention. He accordingly
offered it to the United States for the sum of $100,000. There
followed a distressing example of official stupidity and lack of
foresight. With the opportunity to own and control the nation's
telegraph lines before it the Government declined the offer. This
action was taken at the recommendation of the Hon. Cave Johnson, then
Postmaster-General, under whose direction the line had been
operated. He had been a member of Congress at the time the original
appropriation was voted, and had ridiculed the project. The nation was
now so unfortunate as to have him as its Postmaster-General, and he
reported "that the operation of the telegraph between Washington and
Baltimore had not satisfied him that, under any rate of postage
that could be adopted, its revenues could be made equal to its
expenditures." And yet the telegraph, here offered to the Government
for $100,000, was developed under private management until it paid a
profit on a capitalization of $100,000,000.

Morse seems to have had a really patriotic motive, as well as a desire
for immediate return and the freedom from further worries, in his
offer to the Government. He was greatly disappointed at its refusal
to purchase, a refusal that was destined to make Morse a wealthy man.
Amos Kendall, who had been Postmaster-General under Jackson, was
now acting as Morse's agent, and they decided to depend upon private
capital. Plans were made for a line between New York and Philadelphia,
and to arouse interest and secure capital the apparatus was exhibited
in New York City at a charge of twenty-five cents a head. The public
refused to patronize in sufficient numbers to even pay expenses,
and the entire exhibition was so shabby, and the exhibitors so
poverty-stricken, that the sleek capitalists who came departed without
investing. Some of the exhibitors slept on chairs or on the floor in
the bare room, and it is related that the man who was later to
give his name and a share of his fortune to Cornell University was
overjoyed at finding a quarter on the sidewalk, as it enabled him to
buy a hearty breakfast. Though men of larger means refused to take
shares, some in humbler circumstances could recognize the great
idea and the wonderful vision which Morse had struggled so long to
establish--a vision of a nation linked together by telegraphy. The
Magnetic Telegraph Company was formed and work started on the line.

In August of 1845 Morse sailed for Europe in an endeavor to enlist
foreign capital. The investors of Europe proved no keener than those
of America, and the inventor returned without funds, but imbued with
increased patriotism. He had become convinced that the telegraph could
and would succeed on American capital alone. In the next year a line
was constructed from Philadelphia to Washington, thus extending
the New York-Philadelphia line to the capital. Henry O'Reilly, of
Rochester, New York, took an active part in this construction work
and now took the contract to construct a line from Philadelphia to St.
Louis. This line was finished by December of 1847.

The path having been blazed, others sought to establish lines of their
own without regard to Morse's patents. One of these was O Reilly, who,
on the completion of the line to St. Louis, began one to Now Orleans,
without authority from Morse or his company. O'Reilly called his
telegraph "The People's Line," and when called to account in the
courts insisted not only that his instruments were different from
Morse's, and so no infringement of his patents, but also that the
Morse system was a harmful monopoly and that "The People's Line"
should be encouraged. It was further urged that Wheatstone in England
and Steinheil in Germany had invented telegraphs before Morse, and
that Professor Henry had invented the relay which made it possible
to operate the telegraph over long distances. The suits resulted in a
legal victory for Morse, and his patents were maintained.

But still other rival companies built lines, using various forms of
apparatus, and though the courts repeatedly upheld Morse's patent
rights, the pirating was not effectively checked. The telegraph had
come to be a necessity and the original company lacked the capital to
construct lines with sufficient rapidity to meet the need. Within
ten years after the first line had been put into operation the more
thickly settled portions of the United States were served by scores
of telegraph lines owned by a dozen different companies. Hardly any of
these were making any money, though the service was poor and the rates
were high. They were all operating on too small a scale and business
uses of the telegraph had not yet developed sufficiently.

An amalgamation of the scattered, competing lines was needed, both
to secure better service for the public and proper dividends for the
investors. This amalgamation was effected by Mr. Hiram Sibley, who
organized the Western Union in 1856. The plan was ridiculed at
the time, some one stating that "The Western Union seems very like
collecting all the paupers in the State and arranging them into a
union so as to make rich men of them." But these pauper companies did
become rich once they were united under efficient management.

The nation was just then stretching herself across to the Pacific.
The commercial importance of California was growing rapidly. By 1857
stage-coaches were crossing the plains and the pony-express riders
were carrying the mail. The pioneers of the telegraph felt that a line
should span the continent. This was then a tremendous undertaking, and
when Mr. Sibley proposed that the Western Union should undertake the
construction of such a line he was met with the strongest opposition.
The explorations of Frémont were not far in the past, and the vast
extent of country west of the Mississippi was regarded as a wilderness
peopled with savages and almost impossible of development. But Sibley
had faith; he was possessed of Morse's vision and Morse's courage.
The Western Union refusing to undertake the enterprise, he began it
himself. The Government, realizing the military and administrative
value of a telegraph line to California, subsidized the work.
Additional funds were raised and a route selected was through Omaha
and Salt Lake City to San Francisco.

The undertaking proved less formidable than had been anticipated,
for, instead of two years, less than five months were occupied in
completing the line. Sibley's tact and ability did much to avoid
opposition by the Indians. He made the red men his friends and
impressed upon them the wonder of the telegraph. When the line was in
operation between Fort Kearney and Fort Laramie he invited the chief
of the Arapahoes at Fort Kearney to communicate by telegraph with
his friend the chief of the Sioux at Fort Laramie. The two chiefs
exchanged telegrams and were deeply impressed. They were told that the
telegraph was the voice of the Manitou or Great Spirit. To convince
them it was suggested that they meet half-way and compare their
experiences. Though they were five hundred miles apart, they started
out on horseback, and on meeting each other found that the line had
carried their words truly. The story spread among the tribes, and so
the telegraph line became almost sacred to the Indians. They might
raid the stations and kill the operators, but they seldom molested the

Among many ignorant peoples the establishment of the telegraph has
been attained with no small difficulty. The Chinese showed a dread of
the telegraph, frequently breaking down the early lines because they
believed that they would take away the good luck of their district.
The Arabs, on the other hand, did not oppose the telegraph. This
is partly because the name is one which they can understand,
_tel_ meaning wire to them, and _araph_, to know. Thus in Arabic
_tele-agraph_ means to know by wire.

Just as the Indians of our own plains had difficulty in understanding
the telegraph, so the primitive peoples in other parts of the world
could scarce believe it possible. A story is told of the construction
of an early line in British India. The natives inquired the purpose of
the wire from the head man.

"The wire is to carry messages to Calcutta," he replied.

"But how can words run along a wire?" they asked.

The head man puzzled for a moment.

"If there were a dog," he replied, "with a tail long enough to reach
from here to Calcutta, and you pinched his tail here, wouldn't he howl
in Calcutta?"

Once Sibley and the other American telegraph pioneers had spanned the
continent, they began plans for spanning the globe. Their idea was to
unite America and Europe by a line stretched through British Columbia,
Alaska, the Aleutian Islands, and Siberia. Siberia had been connected
with European Russia, and thus practically the entire line could be
stretched on land, only short submarine cables being necessary. It was
then seriously doubted that cables long enough to cross the Atlantic
were practicable. The expedition started in 1865, a fleet of thirty
vessels carrying the men and supplies. Tremendous difficulties had
been overcome and a considerable part of the work accomplished when
the successful completion of the Atlantic cable made the work useless.
Nearly three million dollars had been expended by the Western Union
in this attempt. Yet, despite this loss, its affairs were so generally
successful and the need for the telegraph so real that it continued to
thrive until it reached its present remarkable development.

While the line-builders were busy stretching telegraph wires into
almost every city and town in the nation, others were perfecting the
apparatus. Alfred Vail was a leading figure in this work. Already he
had played a large part in designing and constructing the apparatus to
carry out Morse's ideas, and he continued to improve and perfect
until practically nothing remained of Morse's original apparatus. The
original Morse transmitter had consisted of a porte-rule and movable
type. This was cumbersome, and Vail substituted a simple key to make
and break the circuit. Vail had also constructed the apparatus to
emboss the message upon the moving strip of paper, but this he now
improved upon. The receiving apparatus was simplified and the pen was
replaced by a disk smeared with ink which marked the dots and dashes
upon the paper.

As we have noticed, Morse took particular pride in the fact that
the receiving apparatus in his telegraph was self-recording, and
considered this as one of the most important parts of his system. But
when the telegraph began to come into commercial use the operators at
the receiving end noticed that they could read the messages from the
long and short periods between the clicks of the receiving mechanism.
Thus they were taking the message by ear and the recording mechanism
was superfluous. Rules and fines failed to break them of the habit,
and Vail, recognizing the utility of the development, constructed a
receiver which had no recording device, but from which the messages
were read by listening to the clicks as the armature struck against
the frame in which it was set. Thus the telegraph returned in its
elements to the form of Professor Henry's original bell telegraph.

With his bell telegraph and his relay Henry had the elements of a
successful system. He failed, however, to develop them practically or
to introduce them to the attention of the public. He was the man of
science rather than the practical inventor. Alfred Vail, joining with
Morse after the latter had conceived the telegraph, but before
his apparatus was in practical form, was a tireless and invaluable
mechanical assistant. His inventions of apparatus were of the utmost
practical value, and he played a very large part in bringing the
telegraph to a form where it could serve man effectively. After
success had been won Morse did not extend to Vail the credit which it
seems was his due.

Yet, though Morse made free use of the ideas and assistance of others,
he was richly deserving of a major portion of the fame and the rewards
that came to him as inventor of the telegraph. Morse was the directing
genius; he contributed the idea and the leadership, and bore the brunt
of the burdens when all was most discouraging.

Honors were heaped upon Morse both at home and abroad as his telegraph
established itself in all parts of the world. Orders of knighthood,
medals, and decorations were conferred upon him. Though he had failed
to secure foreign patents, many of the foreign governments recognized
the value of his invention, and France, Austria, Belgium, Netherlands,
Russia, Sweden, Turkey, and some smaller nations joined in paying him
a testimonial of four hundred thousand francs. It is to be noticed
that Great Britain did not join in this testimonial, though Morse's
system had been adopted there in preference to the one developed by

In 1871 a statue of Morse was erected in Central Park, New York
City. It was in the spring of the next year that another statue was
unveiled, this time one of Benjamin Franklin, and Morse presided at
the ceremonies. The venerable man received a tremendous ovation on
this occasion, but the cold of the day proved too great a strain upon
him. He contracted a cold which eventually resulted in his death on
April 2, 1872.

While extended consideration cannot be given here to the telegraphic
inventions of Thomas A. Edison, no discussion of the telegraph should
close without at least some mention of his work in this field. Edison
started his career as a telegrapher, and his first inventions were
improvements in the telegraph. His more recent and more wonderful
inventions have thrown his telegraphic inventions into the shadow. On
the telegraph as invented by Morse but one message could be sent over
a single wire at one time. It was later discovered that two messages'
could be sent over the single wire in opposite directions at the
same time. This was called duplex telegraphy. Edison invented duplex
telegraphy by which two messages could be sent over the same wire in
the same direction at the same time. Later he succeeded in combining
the two, which resulted in the quadruplex, by which four messages
may be sent over one wire at one time. Though Edison received
comparatively little for this invention, its commercial value may be
estimated from the statement by the president of the Western Union
that it saved that company half a million dollars in a single year.
Edison's quadruplex system was also adopted by the British lines.

Before this he had perfected an automatic telegraph, work on which
had been begun by George Little, an Englishman. Little could make the
apparatus effective only over a short line and attained no very great
speed. Edison improved the apparatus until it transmitted thirty-five
hundred words a minute between New York and Philadelphia. Such is the
perfection to which Morse's marvel has been brought in the hands of
the most able of modern inventors.

    Experimentation--The First Cables--The Atlantic Cable

    Early Life and Attainments.

The idea of laying telegraph wires beneath the sea was discussed long
before a practical telegraph for use on land had been attained. It
is recorded that a Spaniard suggested submarine telegraphy in 1795.
Experiments were conducted early in the nineteenth century with
various materials in an effort to find a covering for the wires which
would be both a non-conductor of electricity and impervious to water.
An employee of the East India Company made an effort to lay a cable
across the river Hugli as early as 1838. His method was to coat the
wire with pitch inclose it in split rattan, and then wrap the whole
with tarred yarn. Wheatstone discussed a Calais-Dover cable in 1840,
but it remained for Morse to actually lay an experimental cable. We
have already heard of his experiments in New York Harbor in 1842. His
insulation was tarred hemp and India rubber. Wheatstone performed a
similar experiment in the Bay of Swansea a few months later.

Perhaps the first practical submarine cable was laid by Ezra Cornell,
one of Morse's associates, in 1845. He laid twelve miles of cable in
the Hudson River, connecting Fort Lee with New York City. The cable
consisted of two cotton-covered wires inclosed in rubber, and the
whole incased in a lead pipe. This cable was in use for several months
until it was carried away by the ice in the winter of 1846.

These early experimenters found the greatest difficulty in incasing
their wires in rubber, practical methods of working that substance
being then unknown. The discovery of gutta-percha by a Scotch surveyor
of the East India Company in 1842, and the invention of a machine for
applying it to a wire, by Dr. Werner Siemens, proved a great aid
to the cable-makers. These gutta-percha-covered wires were used for
underground telegraphy both in England and on the Continent. Tests
were made with such a cable for submarine work off Dover in 1849, and,
proving successful, the first cable across the English Channel was
laid the next year by John Watkins Brett. The cable was weighted
with pieces of lead fastened on every hundred yards. A few incoherent
signals were exchanged and the communication ceased. A Boulogne
fisherman had caught the new cable in his trawl, and, raising it, had
cut a section away. This he had borne to port as a great treasure,
believing the copper to be gold in some new form of deposit. This
experience taught the need of greater protection for a cable, and the
next year another was laid across the Channel, which was protected by
hemp and wire wrappings. This proved successful. In 1852 England
and Ireland were joined by cable, and the next year a cable was laid
across the North Sea to Holland. The success of these short cables
might have promised success in an attempt to cross the Atlantic had
not failures in the deep water of the Mediterranean made it seem an

We have noted that Morse suggested the possibility of uniting Europe
and America by cable. The same thought had occurred to others, but the
undertaking was so vast and the problems so little understood that for
many years none were bold enough to undertake the project. A telegraph
from New York to St. John's, Newfoundland, was planned, however, which
was to lessen the time of communication between the continents.
News brought by boats from England could be landed at St. John's and
telegraphed to New York, thus saving two days. F.N. Gisborne secured
the concession for such a line in 1852, and began the construction.
Cables were required to connect Newfoundland with the continent, and
to cross the Gulf of St. Lawrence, but the rest of the line was to be
strung through the forests.

Before much had been accomplished, Gisborne had run out of funds,
and work was suspended. In 1854 Gisborne met Cyrus West Field, of
New York, a retired merchant of means. Field became interested in
Gisborne's project, and as he examined the globe in his library the
thought occurred to him that the line to St. John's was but a start on
the way to England. The idea aroused his enthusiasm, and he determined
to embark upon the gigantic enterprise. He knew nothing of telegraph
cables or of the sea-bottom, and so sought expert information on the

One important question was as to the condition of the sea-bottom on
which the cable must rest. Lieutenant Berryman of the United States
Navy had taken a series of soundings and stated that the sea-bottom
between Newfoundland and Ireland was a comparatively level plateau
covered with soft ooze, and at a depth of about two thousand fathoms.
This seemed to the investigators to have been provided for the
especial purpose of receiving a submarine cable, so admirably was it
suited to this purpose. Morse was consulted, and assured Field that
the project was entirely feasible, and that a submarine cable once
laid between the continents could be operated successfully.

Field thereupon adopted the plans of Gisborne as the first step in the
larger undertaking. In 1855 an attempt was made to lay a cable across
the Gulf of St. Lawrence, but a storm arose, and the cable had to be
cut to save the ship from which it was being laid. Another attempt
was made the following summer with better equipment, and the cable was
successfully completed. Other parts of the line had been finished, the
telegraph now stretched a thousand miles toward England, and New York
was connected with St. John's.

Desiring more detailed information of the ocean-bed along the proposed
route, Field secured the assistance of the United States and British
governments. Lieutenant Berryman, U.S.N., in the _Arctic_, and
Lieutenant Dayman, R.N., in the _Cyclops_, made a careful survey.
Their soundings revealed a ridge near the Irish coast, but the slope
was gradual and the general conditions seemed especially favorable.

The preliminary work had been done by an American company with Field
at the head and Morse as electrician. Now Field went to England
to secure capital sufficient for the larger enterprise. With the
assistance of Mr. J.W. Brett he organized the Atlantic Telegraph
Company, Field himself supplying a quarter of the capital. Associated
with Field and Brett in the leadership of the enterprise was Charles
Tiltson Bright, a young Englishman who became engineer for the new

Besides the enormous engineering difficulties of producing a cable
long enough and strong enough, and laying it at the bottom of the
Atlantic, there were electrical problems involved far greater than
Morse seems to have realized. It had been discovered that the passage
of a current through a submarine cable is seriously retarded.
The retarding of the current as it passes through the water is a
difficulty that does not exist with the land telegraph stretched on
poles. Faraday had demonstrated that this retarding was caused by
induction between the electricity in the wire and the water about the
cable. The passage of the current through the wire induces currents in
the water, and these moving in the opposite direction act as a drag on
the passage of the message through the wire. What the effect of this
phenomenon would be on a cable long enough to cross the Atlantic wan
a serious problem that required deep study by the company's engineers.
It seemed entirely possible that the messages would move so slowly
that the operation of the cable, once it was laid, would not pay.

Faraday failed to give any definite information on the subject, but
Professor William Thomson worked out the law of retardation accurately
and furnished to the cable-builders the accurate information which
was required. Doctor Whitehouse, electrician for the Atlantic Company,
conducted some experiments of his own and questioned the accuracy of
Thomson's statements. Thomson maintained his position so ably, and
proved himself so thoroughly a master of the subject that Field and
his associates decided to enlist him in the enterprise. This addition
to the forces was one of the utmost importance. William Thomson,
later to become Lord Kelvin, was probably the ablest scientist of his
generation, and was destined to prove his great abilities in his early
work with the Atlantic cable.

William Thomson was born in Belfast, Ireland, in 1824. His father was
a teacher and took an especially keen interest in the affairs of his
boys because their mother had died while William was very young.
When William was eight years of age his father removed to Glasgow,
Scotland, where he had secured the chair of mathematics in Glasgow
University. His early education he secured from his father, and this
training, coupled with his natural brilliancy, enabled him to develop
genuine precocity. At the age of eight he attended his father's
university lectures as a visitor, and it is reported that on one
occasion he answered his father's questions when all of the class had
failed. At the age of ten he entered the university, together with
his brother James, who was but two years older. The brothers displayed
marked interest in science and invention, eagerly pursued their
studies in these branches, and performed many electrical experiments

James took the degrees B.A. and M.A. in successive years. Though
William also passed the examinations, he did not take the degrees,
because he had decided to go to Cambridge, and it was thought best
that he take all his degrees from that great school. In writing to
his older brother at this time, William was accustomed to sign himself
"B.A.T.A.I.A.P.," which signified "B.A. to all intents and purposes."
After finishing their work at Glasgow the boys traveled extensively on
the Continent.

At seventeen William entered St. Peter's College, Cambridge University,
taking courses in advanced mathematics and continuing to distinguish
himself. He took an active part in the life of the university, making
something of a record us an athlete, winning the silver sculls, and
rowing on a 'varsity crew which took the measure of Oxford in the
great annual boat-race. He also interested himself in literature and
music, but his real passion was science. Already he had written many
learned essays on mathematical electricity and was accomplishing
valuable research work. On the completion of his work at Cambridge he
secured a fellowship which brought him an income of a thousand dollars
a year and enabled him to pursue his studies in Paris.

When he was but twenty-two years of age he was made professor of
natural philosophy at the University of Glasgow. Though young,
he proved entirely successful, and wan immensely popular with his
students. At that time the university had no experimental laboratory,
and Professor Thomson and his pupils performed their experiments
in the professor's room and in an abandoned coal-cellar, slowly
developing a laboratory for themselves. His development continued
until, when at the age of thirty-three he was called upon to assist
with the work of laying an Atlantic cable, he was possessed of
scientific attainments which made him invaluable among the cable

    Discoveries--Their Part in Designing and Constructing an Improved

Field and his business associates were extremely anxious that the
cable be laid with all possible speed, and little time was allowed the
engineers and electricians for experimentation. The work of building
the cable was begun early in 1857 by two English firms. It consisted
of seven copper wires covered with gutta-percha and wound with tarred
hemp. Over this were wound heavy iron wires to give protection and
added strength. The whole weighed about a ton to the mile, and was
both strong and flexible. The distance from the west coast of Ireland
to Newfoundland being 1,640 nautical miles, it was decided to supply
2,500 miles of cable, an extra length being, of course, necessary
to allow for the inequalities at the bottom of the sea, and the
possibility of accident.

The British and American governments had already provided subsidies,
and they now supplied war-ships for use in the work of laying the
cable. The _Agamemnon_, one of the largest of England's war-ships, and
the _Niagara_, giant of the United States Navy, were to do the actual
work of cable-laying, the cable being divided between them. They were
accompanied by the United States frigate _Susquehanna_ and the
British war-ships _Leopard_ and _Cyclops_. In August of 1857 the fleet
assembled on the Irish coast for the start, and the American sailors
landed the end of the cable amid great ceremony.

The work of cable-laying was begun by the _Niagara_, which steamed
slowly away, accompanied by the fleet. The great cable payed out
smoothly as the Irish coast was left behind and the frigate increased
her speed. The submarine hill with its dangerous slopes was safely
passed, and it was felt that the greatest danger was past. The
paying-out machinery seemed to be working perfectly. Telegraphic
communication was constantly maintained with the shore end. For six
days all went well and nearly four hundred miles of cable had been

With the cable dropping to the bottom two miles down it was found
that it was flowing out at the rate of six miles an hour while the
_Niagara_ was steaming but four. It was evident that the cable was
being wasted, and to prevent its running out too fast at this great
depth the brake controlling the flow of the cable was tightened. The
stern of the vessel rising suddenly on a wave, the strain proved too
great and the cable parted and was lost. Instant grief swept over
the ship and squadron, for the heart of every one was in the great
enterprise. It was felt that it would be useless to attempt to grapple
the cable at this great depth, and there seemed nothing to do but
abandon it and return.

The loss of the cable and of a year's time--since another attempt
could not be made until the next season--resulted in a total loss
to the company of half a million dollars. Public realization of the
magnitude of the task had been awakened by the failure of the first
expedition and Field found it far from easy to raise additional
capital. It was finally accomplished, however, and a new supply of
cable was constructed.

Professor Thomson had been studying the problems of submarine
telegraphy with growing enthusiasm, and had now arrived at the
conclusion that the conductivity of the cable depended very largely
upon the purity of the copper employed. He accordingly saw to it that
in the construction of the new section all the wires were carefully
tested and such as did not prove perfect were discarded. In the mean
time the engineers were busy improving the paying-out machinery. They
designed an automatic brake which would release the cable instantly
upon the strain becoming too great. It was thus hoped to avoid a
recurrence of the former accident. Chief-Engineer Bright also arranged
a trial trip for the purpose of drilling the staff in their various

The same vessels were provided to lay the cable on the second attempt
and the fleet sailed in June of 1858, this time without celebration or
public ceremony. On this occasion the recommendation of Chief-Engineer
Bright was followed, and it was arranged that the _Niagara_ and
_Agamemnon_ should meet in mid-ocean, there splice the cable together
and proceed in opposite directions, laying the cable simultaneously.
On this expedition Professor Thomson was to assume the real scientific
leadership, Professor Morse, though he retained his position with the
company, taking no active part.

The ships had not proceeded any great distance before they ran into a
terrible gale. The _Agamemnon_ had an especially difficult time of
it, her great load of cable overbalancing the ship and threatening
to break loose again and again and carry the great vessel and her
precious cargo to the bottom. The storm continued for over a week, and
when at last it had blown itself out the _Agamemnon_ resembled a wreck
and many of her crew had been seriously injured. But the cable
had been saved and the expedition was enabled to proceed to the
rendezvous. The _Niagara_, a larger ship, had weathered the storm
without mishap.

The splice was effected on Saturday, the 26th, but before three miles
had been laid the cable caught in the paying-out machinery on the
_Niagara_ and was broken off. Another splice was made that evening and
the ships started again. The two vessels kept in communication with
each other by telegraph as they proceeded, and anxious inquiries and
many tests marked the progress of the work. When fifty miles were
out, the cable parted again at some point between the vessels and they
again sought the rendezvous in mid-Atlantic. Sufficient cable still
remained and a third start was made. For a few days all went well and
some four hundred miles of cable had been laid with success as the
messages passing from ship to ship clearly demonstrated. Field,
Thomson, and Bright began to believe that their great enterprise was
to be crowned with success when the cable broke again, this time about
twenty feet astern of the _Agamemnon_. This time there was no apparent
reason for the mishap, the cable having parted without warning when
under no unusual strain.

The vessels returned to Queenstown, and Field and Thomson went to
London, where the directors of the company were assembled. Many were
in favor of abandoning the enterprise, selling the remaining cable
for what it would bring, and saving as much of their investment as
possible. But Field and Thomson were not of the sort who are easily
discouraged, and they managed to rouse fresh courage in their
associates. Yet another attempt was decided upon, and with replenished
stores the _Agamemnon_ and _Niagara_ once again proceeded to the

The fourth start was made on the 29th of July. On several occasions as
the work progressed communication failed, and Professor Thomson on
the _Agamemnon_ and the other electricians on the _Niagara_ spent many
anxious moments fearing that the line had again been severed. On each
occasion, however, the current resumed. It was afterward determined
that the difficulties were because of faulty batteries rather than
leaks in the cable. On both ships bad spots were found in the cable
as it was uncoiled and some quick work was necessary to repair them
before they dropped into the sea, since it was practically impossible
to stop the flow of the cable without breaking it. The _Niagara_
had some narrow escapes from icebergs, and the _Agamemnon_ had
difficulties with ships which passed too close and a whale which swam
close to the ship and grazed the precious cable. But this time there
was no break and the ships approached their respective destinations
with the cable still carrying messages between them. The _Niagara_
reached the Newfoundland coast on August 4th, and early the next
morning landed the cable in the cable-house at Trinity Bay. The
_Agamemnon_ reached the Irish coast but a few hours later, and her end
of the cable was landed on the afternoon of the same day.

The public, because of the repeated failures, had come to look upon
the cable project as a sort of gigantic wild-goose chase. The news
that a cable had at last been laid across the ocean was received with
incredulity. Becoming convinced at last, there was great rejoicing
in England and America. Queen Victoria sent to President Buchanan
a congratulatory message in which she expressed the hope "that the
electric cable which now connects Great Britain with the United
States will prove an additional link between the two nations, whose
friendship is founded upon their mutual interest and reciprocal
esteem." The President responded in similar vein, and expressed the
hope that the neutrality of the cable might be established.

Honors were showered upon the leaders in the enterprise. Charles
Bright, the chief engineer, was knighted, though he was then but
twenty-six years of age. Banquet after banquet was held in England at
which Bright and Thomson were the guests of honor. New York celebrated
in similar fashion. A grand salute of one hundred guns was fired, the
streets were decorated, and the city was illuminated at night.
The festivities rose to the highest pitch in September with Field
receiving the plaudits of all New York. Special services were held in
Trinity Church, and a great celebration was held in Crystal Palace.
The mayor presented to Field a golden casket, and the ceremony was
followed by a torchlight parade. That very day the last message went
over the wire.

The shock to the public was tremendous. Many insisted that the cable
had never been operated and that the entire affair was a hoax. This
was quickly disproved. Aside from the messages between Queen and
President many news messages had gone over the cable and it had proved
of great value to the British Government. The Indian mutiny had been
in progress and regiments in Canada had received orders by mail to
sail for India. News reached England that the mutiny was at an end,
and the cable enabled the Government to countermand the orders, thus
saving a quarter of a million dollars that would have been expended in
transporting the troops.

The engineers to whom the operations of the cable had been intrusted
had decided that very high voltages were necessary to its successful
operation. They had accordingly installed huge induction coils and
sent currents of two thousand volts over the line. Even this voltage
had failed to operate the Morse instruments, the drag by induction
proving too great. The strain of this high voltage had a very serious
effect upon the insulation. Abandoning the Morse instruments and
the high voltage, recourse was then had to Professor Thomson's
instruments, which proved entirely effective with ordinary battery

Because of the effect of induction the current is much delayed
in traveling through a long submarine cable and arrives in waves.
Professor Thomson devised his mirror galvanometer to meet this
difficulty. This device consists of a large coil of very fine wire, in
the center of which, in a small air-chamber, is a tiny mirror. Mounted
on the back of the mirror are very small magnets. The mirror is
suspended by a fiber of the finest silk. Thus the weakest of currents
coming in over the wire serve to deflect the mirror, and a beam
of light being directed upon the mirror and reflected by it upon a
screen, the slightest movement of the mirror is made visible. If the
mirror swings too far its action is deadened by compressing the air in
the chamber. The instrument is one of the greatest delicacy. Such
was the greatest contribution of Professor Thomson to submarine
telegraphy. Without it the cable could not have been operated even
for a short period. Had it been used from the first the line would not
have been ruined and might have been used for a considerable period.

Professor Thomson together with Engineer Bright made a careful
investigation of the causes of failure. The professor pointed out
that had the mirror galvanometer been used with a moderate current the
cable could have been continued in successful operation. Ha continued
to improve this apparatus and at the same time busied himself with
a recording instrument to be used for cable work. Both Thomson and
Bright had recommended a larger and stronger cable, and other failures
in cable-laying in the Red Sea and elsewhere in the next few years
bore out their contentions. But with each failure new experience was
gained and methods were perfected. Professor Thomson continued his
work with the utmost diligence and continued to add to the fund of
scientific knowledge on the subject. So it was that he was prepared to
take his place as scientific leader of the next great effort.

The early 'sixties were trying years for the cable pioneers. It
required all of Field's splendid genius and energy to keep the project
alive. In the face of repeated failures, and doubt as to whether
messages could be sent rapidly enough to make any cable a commercial
success, it was extremely difficult to raise fresh capital. America
continued to evince interest in the cable, but with, the Civil War in
progress it was not easy to raise funds. But no discouragement could
deter Field. Though he suffered severely from seasickness, he crossed
the Atlantic sixty-four times in behalf of the great enterprise which
he had begun.

It was necessary to raise three million dollars to provide a cable of
the improved type decided upon and to install it properly. The English
firm of Glass, Eliot & Company, which was to manufacture the cable,
took a very large part of the stock. The new cable was designed in
accordance with the principles enunciated by Professor Thomson. The
conductor consisted of seven wires of pure copper, weighing three
hundred pounds to the mile. This copper core was covered with
Chatterton's compound, which served as water-proofing. This was
surrounded by four layers of gutta-percha, cemented together by the
compound, and about this hemp was wound. The outer layer consisted
of eighteen steel wires wound spirally, each being covered with a
wrapping of hemp impregnated with a preservative solution. The new
cable was twice as heavy as the old and more than twice as strong, a
great advance having been made in the methods of manufacturing steel

It was decided that the cable should, be laid by one vessel, instead
of endeavoring to work from two as in the past. Happily, a boat was
available which was fitted to carry this enormous burden. This was
the _Great Eastern_, a mammoth vessel far in advance of her time.
This great ship of 22,500 tons had been completed in 1857, but had not
proved a commercial success. The docks of that day were not adequate,
the harbors were not deep enough, and the cargoes were insufficient.
She had long lain idle when she was secured by the cable company and
fitted out for the purpose of laying the cable, which was the first
useful work which had been found for the great ship. The 2,300 miles
of heavy cable was coiled into the hull and paying-out machinery was
installed upon the decks. Huge quantities of coal and other supplies
were added.

Capt. James Anderson of the Cunard Line was placed in command of the
ship for the expedition, with Captain Moriarty, R.N., as navigating
officer. Professor Thomson and Mr. C.F. Varley represented the
Atlantic Telegraph Company as electricians and scientific advisers.
Mr. Samuel Canning was engineer in charge for the contractors. Mr.
Field was also on board.

It was on July 23, 1865, that the expedition started from the Irish
coast, where the eastern end of the cable had been landed. Less than a
hundred miles of cable had been laid when the electricians discovered
a fault in the cable. The _Great Eastern_ was stopped, the course was
retraced, and the cable picked up until the fault was reached. It was
found that a piece of iron wire had in some way pierced the cable
so that the insulation was ruined. This was repaired and the work of
laying was again commenced. Five days later, when some seven hundred
miles of cable had been laid, communication was again interrupted, and
once again they turned back, laboriously lifting the heavy cable from
the depths, searching for the break. Again a wire was found thrust
through the cable, and this occasioned no little worry, as it was
feared that this was being done maliciously.

It was on August 2d that the next fault was discovered. Nearly
two-thirds of the cable was now in place and the depth was here over
one mile. Raising the cable was particularly difficult, and just at
this juncture the _Great Eastern's_ machinery broke down, leaving her
without power and at the mercy of the waves. Subjected to an enormous
strain, the precious cable parted and was lost. Despite the great
depth, efforts were made to grapple the lost cable. Twice the cable
was hooked, but on both occasions the rope parted and after days of
tedious work the supply of rope was exhausted and it was necessary
to return to England. Still another cable expedition had ended in

Field, the indomitable, began all over again, raising additional funds
for a new start. The _Great Eastern_ had proved entirely satisfactory,
and it was hoped that with improvements in the grappling-gear the
cable might be recovered. The old company gave way before a new
organization known as the Anglo-American Telegraph Company. It was
decided to lay an entirely new cable, and then to endeavor to complete
the one partially laid in 1865.

With no services other than private prayers at the station on the
Irish shore, the _Great Eastern_ steamed away for the new effort on
July 13, 1866. This time the principal difficulties arose within the
ship. Twice the cable became tangled in the tanks and it was necessary
to stop the ship while the mass was straightened out. Most of the
time the "coffee-mill," as the seamen called the paying-out machinery,
ground steadily away and the cable sank into the sea. As the work
progressed Field and Thomson, who had suffered so many failures in
their great enterprise, watched with increasing anxiety. They were
almost afraid to hope that the good fortune would continue.

Just two weeks after the Irish coast had been left behind the _Great
Eastern_ approached Newfoundland just as the shadows of night were
added to those of a thick fog. On the next morning, July 28th, she
steamed into Trinity Bay, where flags were flying in the little town
in honor of the great accomplishment. Amid salutes and cheers
the cable was landed and communication between the continents was
established. Almost the first news that came over the wire was that of
the signing of the treaty of peace which ended the war between Prussia
and Austria.

Early in August the _Great Eastern_ again steamed away to search for
the cable broken the year before. Arriving on the spot, the grapples
were thrown out and the tedious work of dragging the sea-bottom was
begun. After many efforts the cable was finally secured and raised to
the surface. A new section was spliced on and the ship again turned
toward America. On September 7th the second cable was successfully
landed, and two wires were now in operation between the continents.
Thus was the great task doubly fulfilled. Once again there were public
celebrations in England and America. Field received the deserved
plaudits of his countrymen and Thomson was knighted in recognition of
his achievements.


The new cables proved a success and were kept in operation for many
years. Thomson's mirror receiver had been improved until it displayed
remarkable sensitiveness. Using the current from a battery placed in
a lady's thimble, a message was sent across the Atlantic through one
cable and back through the other. Professor Thomson was to give to
submarine telegraphy an even more remarkable instrument. The mirror
instrument did not give a permanent record of the messages. The
problem of devising a means of recording the messages delicate enough
so that it could be operated with rapidity by the faint currents
coming over a long cable was extremely difficult. But Thomson solved
it with his siphon recorder. In this a small coil is suspended between
the poles of a large magnet; the coil being free to turn upon its
axis. When the current from the cable passes through the coil it
moves, and so varies the position of the ink-siphon which is attached
to it. The friction of a pen on paper would have proved too great a
drag on so delicate an instrument, and so a tiny jet of ink from the
siphon was substituted. The ink is made to pass through the siphon
with sufficient force to mark down the message by a delightfully
ingenious method. Thomson simply arranged to electrify the ink, and
it rushes through the tiny opening on to the paper just as lightning
leaps from cloud to earth.

Professor, now Sir, Thomson continued to take an active part in the
work of designing and laying new cables. Not only did he contribute
the apparatus and the scientific information which made cables
possible, but he attained renown as a physicist and a scientist in
many other fields. In 1892 he was given the title of Lord Kelvin, and
it was by this name that he was known as the leading physicist of his
day. He survived until 1907.

To Cyrus W. Field must be assigned a very large share of the credit
for the establishment of telegraphic communication between the
continents. He gave his fortune and all of his tremendous energy and
ability to the enterprise and kept it alive through failure after
failure. He was a promoter of the highest type, the business man who
recognized a great human need and a great opportunity for service.
Without his efforts the scientific discoveries of Thomson could
scarcely have been put to practical use.

The success of the first cable inspired others. In 1869 a cable from
France to the United States was laid from the _Great Eastern_. In 1875
the Direct United States Cable Company laid another cable to England,
which was followed by another cable to France. One cable after another
was laid until there are now a score. This second great development in
communication served to bring the two continents much closer together
in business and in thought and has proved of untold benefit.



    The Family's Interest in Speech Improvement--Early Life-Influence of
    Sir Charles Wheatstone--He Comes to America--Visible Speech and the
    Mohawks--The Boston School for Deaf Mutes--The Personality of Bell.

The men of the Bell family, for three generations, have interested
themselves in human speech. The grandfather, the father, and the
uncle of Alexander Graham Bell were all elocutionists of note. The
grandfather achieved fame in London; the uncle, in Dublin; and the
father, in Edinburgh. The father applied himself particularly to
devising means of instructing the deaf in speech. His book on _Visible
Speech_ explained his method of instructing deaf mutes in speech by
the aid of their sight, and of teaching them to understand the speech
of others by watching their lips as the words are spoken.

Alexander Graham Bell was born in Edinburgh in 1847, and received
his early education in the schools of that city. He later studied
at Warzburg, Germany, where he received the degree of Doctor of
Philosophy. He followed very naturally in the footsteps of his father,
taking an early interest in the study of speech. He was especially
anxious to aid his mother, who was deaf.

As a boy he exhibited a genius for invention, as well as for
acoustics. Much of this was duo to the wise encouragement of his
father. He himself has told of a boyhood invention.

    My father once asked my brother Melville and myself to try to
    make a speaking-machine, I don't suppose he thought we could
    produce anything of value, in itself. But he knew we could not
    even experiment and manufacture anything which even tried to
    speak, without learning something of the voice and the
    throat; and the mouth--all that wonderful mechanism of sound
    production in which he was so interested.

    So my brother and I went to work. We divided the task--he was
    to make the lungs and the vocal cords, I was to make the mouth
    and the tongue. He made a bellows for the lungs and a very
    good vocal apparatus out of rubber. I procured a skull and
    molded a tongue with rubber stuffed with cotton wool, and
    supplied the soft parts of the throat with the same material
    Then I arranged joints, so the jaw and the tongue could move.
    It was a great day for us when we fitted the two parts of the
    device together. Did it speak? It squeaked and squawked a
    good deal, but it made a very passable imitation of
    "Mam-ma--Mam-ma." It sounded very much like a baby. My father
    wanted us to go on and try to get other sounds, but we were so
    interested in what we had done we wanted to try it out. So we
    proceeded to use it to make people think there was a baby in
    the house, and when we made it cry "Mam-ma," and heard doors
    opening and people coming, we were quite happy. What has
    become of It? Well, that was across the ocean, in Scotland,
    but I believe the mouth and tongue part that I made is in
    Georgetown somewhere; I saw it not long ago.

The inventor tells of another boyhood invention that, though it had no
connection with sound or speech, shows his native ingenuity. Again we
will tell it in his own words.

    I remember my first invention very well. There were several of
    us boys, and we were fond of playing around a mill where they
    ground wheat into flour. The miller's son was one of the
    boys, and I am afraid he showed us how to be a good deal of a
    nuisance to his father. One day the miller called us into the
    mill and said, "Why don't you do something useful instead of
    just playing all the time?" I wasn't afraid of the miller as
    much as his son was, so I said, "Well, what can we do that
    is useful?" He took up a handful of wheat, ran it over in his
    hand and said: "Look at that! If you could manage to get the
    husks off that wheat, that would be doing something useful!"

    So I took some wheat home with me and experimented. I found
    the husks came off without much difficulty. I tried brushing
    them off and they came off beautifully. Then it occurred to me
    that brushing was nothing but applying friction to them. If
    I could brush the husks off, why couldn't the husks be rubbed

    There was in the mill a machine--I don't know what it was
    for--but it whirled its contents, whatever it was, around in
    a drum. I thought, "Why wouldn't the husks come off if the raw
    wheat was whirled around in that drum?" So back I went to the
    miller and suggested the idea to him.

    "Why," he said, "that's a good idea." So he called his foreman
    and they tried it, and the husks came off beautifully, and
    they've been taking husks off that way ever since. That was
    my very first invention, and it led me to thinking for myself,
    and really had quite an influence on my way and methods of

Up to his sixteenth year young Bell's reading consisted largely of
novels, poetry, and romantic tales of Scotch heroes. But in addition
he was picking up some knowledge of anatomy, music, electricity, and
telegraphy. When he was but sixteen years of age his father secured
for him a position as teacher of elocution and this necessarily turned
his thought into more serious channels. He now spent his leisure
studying sound. During this period he made several discoveries in
sound which were of some small importance.

When he was twenty-one years of age he went to London and there had
the good fortune to come to the attention of Charles Wheatstone
and Alex J. Ellis. Ellis was at that time president of the London
Philological Society, and had translated Helmholtz's _The Sensation
of Tone_ into English. He had made no little progress with sound, and
demonstrated to Bell the methods by which German scientists had caused
tuning-forks to vibrate by means of electro-magnets and had combined
the tones of several tuning-forks in an effort to reproduce the sound
of the human voice. Helmholtz had performed this experiment simply to
demonstrate the physical basis of sound, and seems to have had no idea
of its possible use in telephony.

That an electro-magnet could vibrate a tuning-fork and so produce
sound was an entirely new and fascinating idea to the youth. It
appealed to his imagination, quickened by his knowledge of speech.
"Why not an electrical telegraph?" he asked himself. His idea seems to
have been that the electric current could carry different notes over
the wire and reproduce them by means of the electro-magnet. Although
Bell did not know it, many others were struggling with the same
problem, the answer to which proved most elusive. It gave Bell a
starting-point, and the search for the telephone began.

Sir Charles Wheatstone was then England's leading man of science,
and so Bell sought his counsel. Wheatstone received the young man
and listened to his statement of his ideas and ambitions and gave
him every encouragement. He showed him a talking-machine which
had recently been invented by Baron de Kempelin, and gave him the
opportunity to study it closely. Thus Bell, the eager student, the
unknown youth of twenty-two, came under the influence of Wheatstone,
the famous scientist and inventor of sixty-seven. This influence
played a great part in shaping Bell's career, arousing as it did his
passion for science. This decided him to devote himself to the problem
of reproducing sounds by mechanical means. Thus a new improvement in
the means of human communication was being sought and another pioneer
of science was at work.

The death of the two brothers of the young scientist from
tuberculosis, and the physician's report that he himself was
threatened by the dread malady, forced a change in his plans and
withdrew him from an atmosphere which was so favorable to the
development of his great ideas. He was told that he must seek a new
climate and lead a more vigorous life in the open. Accompanied by his
father, he removed to America and at the age of twenty-six took up the
struggle for health in the little Canadian town of Brantford.

He occupied himself by teaching his father's system of visible speech
among the Mohawk Indians. In this work he met with no little success.
At the same time he was gaining in bodily vigor and throwing off the
tendency to consumption which had threatened his life. He did not
forget the great idea which filled his imagination and eagerly sought
the telephone with such crude means as were at hand. He succeeded in
designing a piano which, with the aid of the electric current, could
transmit its music over a wire and reproduce it.

While lecturing in Boston on his system of teaching visible speech,
the elder Bell received a request to locate in that city and take up
his work in its schools. He declined the offer, but recommended his
son as one entirely competent for the position. Alexander Graham
Bell received the offer, which he accepted, and he was soon at work
teaching the deaf mutes in the school which Boston had opened for
those thus afflicted. He met with the greatest success in his work,
and ere long achieved a national reputation. During the first year of
his work, 1871, he was the sensation of the educational world. Boston
University offered him a professorship, in which position he taught
others his system of teaching, with increased success.

The demand for his services led him to open a School of Vocal
Physiology. He had made some improvements in his father's system for
teaching the deaf and dumb to speak and to understand spoken words,
and displayed great ability as a teacher. His experiments with
telegraphy and telephony had been laid aside, and there seemed little
chance that he would turn from the work in which he was accomplishing
so much for so many sufferers, and which was bringing a comfortable
financial return, and again undertake the tedious work in search for a

Fortunately, Bell was to establish close relationships with those who
understood and appreciated his abilities and gave him encouragement
in his search for a new means of communication. Thomas Sanders, a
resident of Salem, had a five-year-old son named Georgie who was a
deaf mute. Mr. Sanders sought Bell's tutelage for his son, and it was
agreed that Bell should give Georgie private lessons for the sum of
three hundred and fifty dollars a year. It was also arranged that Bell
was to reside at the Sanders home in Salem. He made arrangements to
conduct his future experiments there.

Another pupil who came to him about this time was Mabel Hubbard, a
fifteen-year-old girl who had lost her hearing and consequently her
powers of speech, through an attack of scarlet fever when an infant.
She was a gentle and lovable girl, and Bell fell completely in love
with his pupil. Four years later he was to marry her and she was
to prove a large influence in helping him to success. She took the
liveliest interest in all of his experiments and encouraged him to new
endeavor after each failure. She kept his records and notes and wrote
his letters. Through her Bell secured the support of her father,
Gardiner G. Hubbard, who was widely known as one of Boston's ablest
lawyers. He was destined to become Bell's chief spokesman and

Hubbard first became aware of Bell's inventive genius when the latter
was calling one evening at the Hubbard home in Cambridge. Bell was
illustrating some mysteries of acoustics with the aid of the piano.
"Do you know," he remarked, "that if I sing the note G close to the
strings of the piano, the G string will answer me?"

This did not impress the lawyer, who asked its significance.

"It is a fact of tremendous importance," answered Bell. "It is
evidence that we may some day have a musical telegraph which will
enable us to send as many messages simultaneously over one wire as
there are notes on that piano."

From that time forward Hubbard took every occasion to encourage Bell
to carry forward his experiments in musical telegraphy.

As a young man Bell was tall and slender, with jet-black eyes and
hair, the latter being pushed back into a curly tangle. He was
sensitive and high-strung, very much the artist and the man of
science. His enthusiasms were intense, and, once his mind was filled
with an idea, he followed it devotedly. He was very little the
practical business man and paid scant attention to the small,
practical details of life. He was so interested in visible speech, and
so keenly alert to the pathos of the lives of the deaf mutes, that he
many times seriously considered giving over all experiments with the
musical telegraph and devoting his entire life and energies to the
amelioration of their condition.

Alexander Graham Bell had not resided at the Sanderses' home very long
before he had fitted the basement up as a workshop. For three years he
haunted it, spending all of his leisure time in his experiments. Here
he had his apparatus, and the basement was littered with a curious
combination of electrical and acoustical devices--magnets, batteries,
coils of wire, tuning-forks, speaking-trumpets, etc. Bell had a great
horror that his ideas might be stolen and was very nervous over any
possible intrusion into his precious workshop. Only the members of
the Sanders family were allowed to enter the basement. He was equally
cautious in purchasing supplies and equipment lest his very purchases
reveal the nature of his experiments. He would go to a half-dozen
different stores for as many articles. He usually selected the night
for his experiments, and pounded and scraped away indefatigably,
oblivious of the fact that the family, as well as himself, was sorely
in need of rest.

"Bell would often awaken me in the middle of the night," says Mr.
Sanders, "his black eyes blazing with excitement. Leaving me to go
down to the cellar, he would rush wildly to the barn and begin to send
me signals along his experimental wires. If I noticed any improvement
in his apparatus he would be delighted. He would leap and whirl around
in one of his 'war-dances,' and then go contentedly to bed. But if
the experiment was a failure he would go back to his work-bench to try
some different plan."

In common with other experimenters who were searching for the
telephone, Bell was experimenting with a sort of musical telegraph.
Eagerly and persistently he sought the means that would replace the
telegraph with its cumbersome signals by a new device which would
enable the human voice itself to be transmitted. The longer he worked
the greater did the difficulties appear. His work with the deaf and
dumb was alluring, and on many occasions he seriously considered
giving over his other experiments and devoting himself entirely to the
instruction of the deaf and dumb and to the development of his system
of making speech visible by making the sound-vibrations visible to the
eye. But as he mused over the difficulties in enabling a deaf mute to
achieve speech nothing else seemed impossible. "If I can make a deaf
mute talk," said Bell, "I can make iron talk."

One of his early ideas was to install a harp at one end of the wire
and a speaking-trumpet at the other. His plan was to transmit
the vibrations over the wire and have the voice reproduced by the
vibrations of the strings of the harp. By attaching a light pencil
or marker to a cord or membrane and causing the latter to vibrate by
talking against it, he could secure tracings of the sound-vibrations.
Different tracings were secured from different sounds. He thus sought
to teach the deaf to speak by sight.

At this time Bell enjoyed the friendship of Dr. Clarence J. Blake, an
eminent Boston aurist, who suggested that the experiments be conducted
with a human ear instead of with a mechanical apparatus in imitation
of the ear. Bell eagerly accepted the idea, and Doctor Blake provided
him with an ear and connecting organs cut from a dead man's head. Bell
soon had the ghastly specimen set up in his workshop. He moistened the
drum with glycerine and water and, substituting a stylus of hay for
the stapes bone, he obtained a wonderful series of curves which showed
the vibrations of the human voice as recorded by the ear. One can
scarce imagine a stranger picture than Bell must have presented in the
conduct of those experiments. We can almost see him with his face the
paler in contrast with his black hair and flashing black eyes as he
shouted and whispered by turns into the ghastly ear. Surely he must
have looked the madman, and it is perhaps fortunate that he was not
observed by impressionable members of the public else they would have
been convinced that the witches had again visited old Salem town to
ply their magic anew. But it was a new and very real and practical
sort of magic which was being worked there.

His experiments with the dead man's ear brought to Bell at least one
important idea. He noted that, though the ear-drum was thin and light,
it was capable of sending vibrations through the heavy bones that
lay back of it. And so he thought of using iron disks or membranes to
serve the purpose of the drum in the ear and arrange them so that
they would vibrate an iron rod. He thought of connecting two such
instruments with an electrified wire, one of which would receive the
sound-vibrations and the other of which would reproduce them after
they had been transmitted along the wire. At last the experimenter
was on the right track, with a conception of a practicable method of
transmitting sound. He now possessed a theoretical knowledge of what
the telephone he sought should be, but there yet remained before him
the enormous task of devising and constructing the apparatus which
would carry out the idea, and find the best way of utilizing the
electrical current for this work.

Bell was now at a critical point in his career and was confronted by
the same difficulty which assails so many inventors. In his constant
efforts to achieve a telephone he had entirely neglected his school of
vocal physiology, which was now abandoned. Georgie Sanders and
Mabel Hubbard were his only pupils. Though Sanders and Hubbard were
genuinely interested in Bell and his work, they felt that he was
impractical, and were especially convinced that his experiments with
the ear and its imitations were entirely useless. They believed that
the electrical telegraph alone presented possibilities, and they told
Bell that unless he would devote himself entirely to the improvement
of this instrument and cease wasting time and money over ear toys
that had no commercial value they would no longer give him financial
support. Hubbard went even further, and insisted that if Bell did not
abandon his foolish notions he could not marry his daughter.

Bell was almost without funds, his closest friends now seemed to turn
upon him, and altogether he was in a sorry plight. Of course Sanders
and Hubbard meant the best, yet in reality they were seeking to drive
their protégé in exactly the wrong direction. As far back as 1860 a
German scientist named Philipp Reis produced a musical telephone
that even transmitted a few imperfect words. But it would not talk
successfully. Others had followed in his footsteps, using the musical
telephone to transmit messages with the Morse code by means of long
and short hums. Elisha Gray, of Chicago, also experimented with the
musical telegraph. At the transmitting end a vibrating steel tongue
served to interrupt the electric current which passed over the wire
in waves, and, passing through the coils of an electro-magnet at the
receiving end, caused another strip of steel located near the magnet
to vibrate and so produce a tone which varied with the current.

All of these developments depended upon the interruption of the
current by some kind of a vibrating contact. The limitations which
Sanders and Hubbard sought to impose upon Bell, had they been obeyed
to the letter, must have prevented his ultimate success. In a letter
to his mother at this time, he said:

    I am now beginning to realize the cares and anxieties of being
    an inventor. I have had to put off all pupils and classes, for
    flesh and blood could not stand much longer such a strain as I
    have had upon me.

But good fortune was destined to come to Bell along with the bad. On
an enforced trip to Washington to consult his patent attorney--a trip
he could scarce raise funds to make--Bell met Prof. Joseph Henry.
We have seen the part which this eminent scientist had played in the
development of the telegraph. Now he was destined to aid Bell, as he
had aided Morse a generation earlier. The two men spent a day over the
apparatus which Bell had with him. Though Professor Henry was fifty
years his senior and the leading scientist in America, the youth was
able to demonstrate that he had made a real discovery.

"You are in possession of the germ of a great invention," said
Henry, "and I would advise you to work at it until you have made it

"But," replied Bell, "I have not got the electrical knowledge that is

"Get it," was Henry's reply.

This proved just the stimulus Bell needed, and he returned to Boston
with a new determination to perfect his great idea.

Bell was no longer experimenting in the Sanderses' cellar, having
rented a room in Boston in which to carry on his work. He had also
secured the services of an assistant, one Thomas Watson, who received
nine dollars a week for his services in Bell's behalf. The funds
for this work were supplied by Sanders and Hubbard jointly, but they
insisted that Bell should continue his experiments with the musical
telegraph. Though he was convinced that the opportunities lay in the
field of telephony, Bell labored faithfully for regular periods with
the devices in which his patrons were interested. The remainder of his
time and energy he put upon the telephone. The basis of his telephone
was still the disk or diaphragm which would vibrate when the
sound-waves of the voice were thrown against it. Behind this
were mounted various kinds of electro-magnets in series with the
electrified wire over which the inventor hoped to send his messages.
For three years they labored with this apparatus, trying every
conceivable sort of disk. It is easy to pass over those three years,
filled as they were with unceasing toil and patient effort, because
they were drab years when little of interest occurred. But these were
the years when Bell and Watson were "going to school," learning how
to apply electricity to this new use, striving to make their apparatus
talk. How dreary and trying these years must have been for the
experimenters we may well imagine. It requires no slight force of will
to hold oneself to such a task in the face of failure after failure.

By June of 1875 Bell had completed a new Instrument. In this the
diaphragm was a piece of gold-beater's skin, which Bell had selected
as most closely resembling the drum in the human ear. This was
stretched tight to form a sort of drum, and an armature of magnetized
iron was fastened to its middle. Thus the bit of iron was free to
vibrate, and opposite it was an electro-magnet through which flowed
the current that passed over the line. This acted as the receiver. At
the other end of the wire was a sort of crude harmonica with a clock
spring, reed, and magnet. Bell and Watson had been working upon their
crude apparatus for months, and finally, on June 2d, sounds were
actually transmitted. Bell was afire with enthusiasm; the first great
step had been taken. The electric current had carried sound-vibrations
along the wire and had reproduced them. If this could be done a
telephone which would reproduce whole words and sentences could be


[Illustration: THOMAS A. WATSON]

So great was Bell's enthusiasm over this achievement that he succeeded
in convincing Sanders and Hubbard that his idea was practical, and
they at last agreed to finance him in his further experiments with the
telephone. A second membrane receiver was constructed, and for many
more weeks the experiments continued. It was found that sounds were
carried from instrument to instrument, but as a telephone they were
still far from perfection. It was not until March of 1876 that Bell,
speaking into the instrument in the workroom, was heard and understood
by Watson at the other instrument in the basement. The telephone had
carried and delivered an intelligible message.

The telephone which Bell had invented, and on which he received a
patent on his twenty-ninth birthday, consisted of two instruments
similar in principle to what we would now call receivers. If you will
experiment with the receiver of a modern telephone you will find
that it will transmit as well as receive sound. The heart of the
transmitter was an electro-magnet in front of which was a drum-like
membrane with a piece of iron cemented to its center opposite the
magnet. A mouthpiece was arranged to throw the sounds of the voice
against the diaphragm, and as the membrane vibrated the bit of iron
upon it--acting as an armature--induced currents corresponding to the
sound-waves, in the coils of the electro-magnet.

Passing over the line the current entered the coils of the tubular
electro-magnet in the receiver. A thin disk of soft iron was fastened
at the end of this. When the current-waves passed through the coils
of the magnet the iron disk was thrown into vibration, thus producing
sound. As it vibrated with the current produced by the iron on
the vibrating membrane in the transmitter acting as an armature,
transmitter and receiver vibrated in unison and so the same sound was
given off by the receiver and made audible to the human ear as was
thrown against the membrane of the transmitter by the voice.

The patent issued to Bell has been described as "the most valuable
single patent ever issued." Certainly it was destined to be of
tremendous service to civilization. It was so entirely new and
original that Bell found difficulty in finding terms in which to
describe his invention to the patent officials. He called it "an
improvement on the telegraph," in order that it might be identified as
an improvement in transmitting intelligence by electricity. In reality
the telephone was very far from being a telegraph or anything in the
nature of a telegraph.

As Bell himself stated, his success was in large part due to the fact
that he had approached the problem from the viewpoint of an expert
in sound rather than as an electrician. "Had I known more about
electricity and less about sound," he said, "I would never have
invented the telephone." As we have seen, those electricians who
worked from the viewpoint of the telegraph never got beyond the
limitations of the instrument and found that with it they could
transmit signals but not sounds. Bell, with his knowledge of the laws
of speech and sound, started with the principles of the
transmission of sound as a basis and set electricity to carrying the

    Stairs--Indifference of the Judges--Enter Don Pedro, Emperor of
    Brazil--Attention and Amazement--Skepticism of the Public--The Aid
    of Gardiner Hubbard--Publicity Campaign.

The Philadelphia Centennial Exposition--America's first great
exposition--opened within a month after the completion of the first
telephone. The public knew nothing of the telephone, and before it
could be made a commercial success and placed in general service
the interest of investors and possible users had to be aroused.
The Centennial seemed to offer an unusual opportunity to place the
telephone before the public. But Bell, like Morse, had no money with
which to push his invention. Hubbard was one of the commissioners of
the exposition, and exerted his influence sufficiently so that a small
table was placed in an odd corner in the Department of Education for
the exhibition of the apparatus. The space assigned was a narrow strip
between the stairway and the wall.

But no provision was made to allow Bell himself to be present. The
young inventor was almost entirely without funds. Sanders and Hubbard
had paid nothing but his room rent and the cost of his experiments. He
had devoted himself to his inventions so entirely that he had lost all
of his professional income. So it was that he was forced to face
the prospect of staying in Boston and allowing this opportunity of
opportunities to pass unimproved. His fiancée, Miss Hubbard, expected
to attend the exposition, and had heard nothing of Bell's inability to
go. He went with her to the station, and as the train was leaving she
learned for the first time that he was not to accompany her. She burst
into tears at the disappointment. Seeing this, Bell dashed madly after
the train and succeeded in boarding it. Without money or baggage, he
nevertheless succeeded in arriving in Philadelphia.

Bell arrived at the exposition but a few days before the judges were
to make their tour of inspection. With considerable difficulty
Hubbard had secured their promise that they would stop and examine
the telephone. They seemed to regard it as a toy not worth their
attention, and the public generally had displayed no interest in the
device. When the day for the inspection arrived Bell waited eagerly.
As the day passed his hope began to fall, as there seemed little
possibility that the judges would reach his exhibit. The Western
Union's exhibit of recording telegraphs, the self-binding harvester,
the first electric light, Gray's musical telegraph, and other
prominently displayed wonders had occupied the attention of the
scientists. It was well past supper-time when they came to Bell's
table behind the stairs, and most of the judges were tired out and
loudly announced their intention of quitting then and there.

At this critical moment, while they were fingering Bell's apparatus
indifferently and preparing for their departure, a strange and
fortunate thing occurred. Followed by a group of brilliantly attired
courtiers, the Emperor of Brazil appeared. He rushed up to Bell
and greeted him with a warmth of affection that electrified the
indifferent judges. They watched the scene in astonishment, wondering
who this young Bell was that he could attract the attention and the
friendship of the Emperor. The Emperor had attended Bell's school for
deaf mutes in Boston when it was at the height of its success, and
had conceived a warm admiration for the young man and taken a
deep interest in his work. The Emperor was ready to examine Bell's
invention, though the judges were not. Bell showed him how to place
his ear to the receiver, and he then went to the transmitter which had
been placed at the other end of the wire strung along the room. The
Emperor waited expectantly, the judges watched curiously. Bell, at a
distance, spoke into the transmitter. In utter wonderment the Emperor
raised his head from the receiver. "My God," he cried, "it talks!"

Skepticism and indifference were at an end among the judges, and they
eagerly followed the example of the Emperor. Joseph Henry, the most
venerable savant of them all, took his place at the receiver. Though
his previous talk with Bell, when the telephone was no more than an
idea, should perhaps have prepared him, he showed equal astonishment,
and instantly expressed his admiration. Next followed Sir William
Thomson, the hero of the cable and England's greatest scientist. After
his return to England Thomson described his sensations.

"I heard," he said, "'To be or not to be ... there's the rub,'
through an electric wire; but, scorning monosyllables, the electric
articulation rose to higher flights, and gave me passages from the
New York newspapers. All this my own ears heard spoken to me with
unmistakable distinctness by the then circular-disk armature of just
such another little electro-magnet as this I hold in my hand."

Thomson pronounced Bell's telephone "the most wonderful thing he had
seen in America." The judges had forgotten that they were hungry and
tired, and remained grouped about the telephone, talking and listening
in turn until far into the evening. With the coming of the next
morning Bell's exhibit was moved from its obscure corner and given the
most prominent place that could be found. From that time forward it
was the wonder of the Centennial.

the work so well as girls.]


LINE, OCTOBER 18, 1892]

Yet but a small part of the public could attend the exposition and
actually test the telephone for themselves. Many of these believed
that it was a hoax, and general skepticism still prevailed. Business
men, though they were convinced that the telephone would carry
spoken messages, nevertheless insisted that it presented no business
possibilities. Hubbard, however, had faith in the invention, and
as Bell was not a business man, he took upon himself the work of
promotion--the necessary, valuable work which must be accomplished
before any big idea or invention may be put at the service of the
public. Hubbard's first move was to plan a publicity campaign which
should bring the new invention favorably to the attention of all,
prove its claims, and silence the skeptics. They were too poor to
set up an experimental line of their own, and so telegraph lines were
borrowed for short periods wherever possible, demonstrations were
given and tests made. The assistance of the newspapers was invoked and
news stories of the tests did much to popularize the new idea.

An opportunity then came to Bell to lecture and demonstrate the
telephone before a scientific body in Essex. He secured the use of a
telegraph line and connected the hall with the laboratory in Boston.
The equipment consisted of old-fashioned box 'phones over a foot long
and eight inches square, built about an immense horseshoe magnet.
Watson was stationed in the Boston laboratory. Bell started his
lecture, with Watson constantly listening over the telephone. Bell
would stop from time to time and ask that the ability of the
telephone to transmit certain kinds of sounds be illustrated. Musical
instruments were played in Boston and heard in Essex; then Watson
talked, and finally he was instructed to sing. He insisted that he was
not a singer, but the voices of others less experienced in speaking
over the crude instruments often failed to carry sufficiently well
for demonstration purposes. So Watson sang, as best he could, "Yankee
Doodle," "Auld Lang Syne," and other favorites. After the lecture had
been completed members of the audience were invited to talk over the
telephone. A few of them mustered confidence to talk with Watson
in Boston, and the newspaper reporters carefully noted down all the
details of the conversation.

The lecture aroused so much interest that others were arranged. The
first one had been free, but admission was charged for the later
lectures and this income was the first revenue Bell had received for
his invention. The arrangements were generally the same for each of
the lectures about Boston. The names of Longfellow, of Holmes, and of
other famous American men of letters are found among the patrons of
some of the lectures in Boston. Bell desired to give lectures in New
York City, but was not certain that his apparatus would operate at
that distance over the lines available. The laboratory was on the
third floor of a rooming-house, and Watson shouted so loud in his
efforts to make his voice carry that the roomers complained. So he
took blankets and erected a sort of tent over the instruments to
muffle the sound. When the signal came from Bell that he was ready for
the test, Watson crawled into the tent and began his shoutings. The
day was a hot one, and by the time that the test had been completed
Watson was completely wilted. But the complaints of the roomers had
been avoided. For one of the New York demonstrations the services of
a negro singer with a rich barytone voice had been secured. Watson had
no little difficulty in rehearsing him for the part, as he objected to
placing his lips close to the transmitter. When the time for the test
arrived he persisted in backing away from the mouthpiece when he sang,
and, though Watson endeavored to hold the transmitter closer to him,
his efforts were of no avail. Finally Bell told Watson that as the
negro could not be heard he would have to sing himself. The girl
operator in the laboratory had assembled a number of her girl
friends to watch the test, and Watson, who did not consider himself
a vocalist, did not fancy the prospect. But there was no one else to
sing, the demonstration must proceed, and finally Watson struck up
"Yankee Doodle" in a quavering voice.

The negro looked on in disgust. "Is that what you wanted me to do,

"Yes," replied the embarrassed Watson.

"Well, boss, I couldn't sing like that."

The telegraph wires which were borrowed to demonstrate the utility of
the telephone proved far from perfect for the work at hand. Many of
the wires were rusted and the insulation was poor. The stations along
the line were likely to cut in their relays when the test was in
progress, and Bell's instruments were not arranged to overcome this
retardation. However, the lectures were a success from the popular
viewpoint. The public flocked to them and the fame of the telephone
grew. So many cities desired the lecture that it finally became
necessary for Bell to employ an assistant to give the lecture for him.
Frederick Gower, a Providence newspaper man, was selected for this
task, and soon mastered Bell's lecture. It was then possible to give
two lectures on the same evening, Bell delivering one, Gower the
other, and Watson handling the laboratory end for both.

Gower secured a contract for the exclusive use of the telephone in New
England, but failed to demonstrate much ability in establishing the
new device on a business basis. How little the possibilities of the
telephone were then appreciated we may understand from the fact that
Gower exchanged his immensely valuable New England rights for the
exclusive right to lecture on the telephone throughout the country.

The success of these lectures made it possible for Bell to marry, and
he started for England on a wedding-trip. The lectures also aroused
the necessary interest and made it possible to secure capital for the
establishment of telephone lines. It also determined Hubbard in his
plan of leasing the telephones instead of selling them. This was
especially important, as it made possible the uniformity of the
efficient Bell system of the present day.

Through public interest had been aroused in the telephone, it was
still very far from being at the service of the nation. The telephone
increases in usefulness just in proportion to the number of your
acquaintances and business associates who have telephones in their
homes or offices. Instruments had to be manufactured on a commercial
scale, telephone systems had to be built up. While the struggles of
the inventor who seeks to apply a new idea are often romantic, the
efforts of the business executives who place the invention, once it
is achieved, at the service of people everywhere, are not less
praiseworthy and interesting.

A very few telephones had been leased to those who desired to
establish private lines, but it was not until May of 1877 that the
first telephone system was established with an exchange by means of
which those having telephones might talk with one another. There was a
burglar-alarm system in Boston which had wires running from six banks
to a central station. The owner of this suggested that telephones be
installed in the banks using the burglar-alarm wires. Hubbard gladly
loaned the instruments for the purpose. Instruments were installed in
the banks without saying anything to the bankers, or making any charge
for the service. One banker demanded that his telephone be removed,
insisting that it was a foolish toy. But even with the crude little
exchange the first system proved its worth. Others were established in
New York, Philadelphia, and other cities on a commercial basis. A man
from Michigan appeared and secured the perpetual rights for his State,
and for his foresight and enterprise he was later to be rewarded by
the sale of these rights for a quarter of a million dollars. The free
service to the Boston bankers was withdrawn and a commercial system
installed there.

But these exchanges served but a few people, and were poorly equipped.
There was, of course, no provision for communication between cities.
With the telephone over a year old, less than a thousand instruments
were in use. But Hubbard, who was directing the destinies of the
enterprise during Bell's absence in Europe, decided that the time
had come to organize. Accordingly the Bell Telephone Association was
formed, with Bell, Hubbard, Sanders, and Watson as the shareholders.
Sanders was the only one of the four with any considerable sum of
money, and his resources were limited. He staked his entire credit in
the enterprise, and managed to furnish funds with which the fight for
existence could be carried on. But a business depression was upon the
land and it was not easy to secure support for the telephone.

The entrance of the Western Union Telegraph Company into the telephone
field brought the affairs of the Bell company to a crisis. As we have
seen, the telegraph company had developed into a great and powerful
corporation with wires stretching across the length and breadth of
the land and agents and offices established in every city and town of
importance. Once the telephone began to be used as a substitute for
the telegraph in conveying messages, the telegraph officials awoke to
the fact that here, possibly, was a dangerous rival, and dropped the
viewpoint that Bell's telephone was a mere plaything. They acquired
the inventions of Edison, Gray, and Dolbear, and entered the telephone
field, announcing that they were prepared to furnish the very best
in telephonic communication. This sudden assault by the most powerful
corporation in America, while it served to arouse public confidence in
the telephone, made it necessary for Hubbard to reorganize his forces
and find a general capable of doing battle against such a foe.

Hubbard's political activities had brought to him a Presidential
appointment as head of a commission on mail transportation. In the
course of the work for the Government he had come much in contact with
a young man named Theodore N. Vail, who was head of the Government
mail service. He had been impressed by Vail's ability and had in turn
introduced Vail to the telephone and aroused his enthusiasm in its
possibilities. This Vail was a cousin of the Alfred Vail who
was Morse's co-worker, and who played so prominent a part in the
development of the telegraph. His experience in the Post-office
Department had given him an understanding of the problems of
communication in the United States, and had developed his executive
ability. Realizing the possibilities of the telephone, he relinquished
his governmental post and cast his fortunes with the telephone
pioneers, becoming general manager of the Bell company.

The Western Union strengthened its position by the introduction of a
new and improved transmitter. This was the work of Thomas Edison, and
was so much better than Bell's transmitter that it enabled the Western
Union to offer much better telephonic equipment. As we have seen,
Bell's transmitter and receiver were very similar, being about the
same as the receiver now in common use. In his transmitter Edison
placed tiny bits of carbon in contact with the diaphragm. As the
diaphragm vibrated under the sound-impulses the pressure upon the
carbon granules was varied. An electric current was passed through
the carbon particles, whose electrical resistance was varied by the
changing pressure from the diaphragm. Thus the current was thrown into
undulations corresponding to the sound-waves, and passed over the
line and produced corresponding sounds in the receiver. Much stronger
currents could be utilized than those generated by Bell's instrument,
and thus the transmitter was much more effective for longer distances.

Bell returned from Europe to find the affairs of his company in a
sorry plight. Only the courage and generalship of Vail kept it in
the field at all. Bell was penniless, having failed to establish
the telephone abroad, even as Morse before him had failed to secure
foreign revenue from his invention. Bell's health failed him, and as
he lay helpless in the hospital his affairs were indeed at a low
ebb. At this juncture Francis Blake, of Boston, came forward with an
improved transmitter which he offered to the Bell company in exchange
for stock. The instrument proved a success and was gladly adopted,
proving just what was needed to make possible successful competition
with the Western Union.

Prolonged patent litigation followed, and after a bitter legal
struggle the Western Union officials became convinced of two things:
one, that the Bell company, under Vail's leadership, would not
surrender; second, that Bell was the original inventor of the
telephone and that his patent was valid. The Western Union, however,
seemed to have strong basis for its claim that the new transmitter of
the Bell people was an infringement of Edison's patent. A compromise
was arranged between the contestants by which the two companies
divided the business of furnishing communication by wire in the
United States. This agreement proved of the greatest benefit to both
organizations, and did much to make possible the present development
and universal service of both the telephone and telegraph. By the
terms of the agreement the Western Union recognized Bell's patent
and agreed to withdraw from the telephone business. The Bell company
agreed not to engage in the telegraph business and to take over the
Western Union telephone system and apparatus, paying a royalty on all
telephone rentals. Experience has demonstrated that the two businesses
are not competitive, but supplement each other. It is therefore proper
that they should work side by side with mutual understanding.

Success had come at last to the telephone pioneers. Other battles were
still to be fought before their position was to be made secure,
but from the moment when the Western Union admitted defeat the Bell
company was the leader. The stock of the company advanced to a point
where Bell, Hubbard, Sanders, and Watson found themselves in the
possession of wealth as a reward for their pioneering.

The Western Union had no sooner withdrawn as a competitor of the Bell
organization than scores of small, local companies sprang up, all
ready to pirate the Bell patent and push the claims of some rival
inventor. A very few of them really tried to establish telephone
systems, but the majority were organized simply to sell stock to a
gullible public. They stirred up a continuous turmoil, and made
much trouble for the larger company, though their patent claims were
persistently defeated in the courts.

Most of the rival claimants who sprang up, once the telephone had
become an established fact and had proved its value, were men of
neither prominence nor scientific attainments. Of a very different
type was Elisha Gray, whose work we have before noticed, and who
now came forward with the claim that he had invented a telephone
in advance of Bell. Gray was a practical man of real scientific
attainments, but, as we have noticed, his efforts in search of a
telephone were from the viewpoint of a musical telegraph and so
destined to failure. It has frequently been stated that Gray filed
his application for a patent on a telephone of his invention but a
few minutes after Bell, and so Bell wrested the honor from him by the
scantiest of margins. A careful reading of the testimony brought out
in Gray's suit against Bell does not support such a statement. While
Bell filed an application for a patent on a completed, invention, Gray
filed, a few moments later, a caveat. This was a document, stating
that he hoped to invent a telephone of a certain kind therein stated,
and would serve to protect his rights until he should have time to
perfect it. Thus Gray did not have a completed invention, and he later
failed to perfect a telephone along the lines described in his caveat.
The decision of the court supported Bell's claims in full.

Another of the Western Union's telephone experts, Professor Dolbear,
of Tufts College, also sought to make capital of his knowledge of the
telephone. He based his claims upon an improvement of the Reis
musical telegraph, which had formed the starting-point for so many
experimenters. The case fell flat, however, for when the apparatus was
brought into court no one could make it talk.

None of the attacks upon Bell's claim to be the original inventor
of the telephone aroused more popular interest at the time than the
famous Drawbaugh case. Daniel Drawbaugh was a country mechanic with a
habit of reading of the new inventions in the scientific journals. He
would work out models of many of these for himself, and, showing them
very proudly, often claim them as his own devices. Drawbaugh was
now put forward by the opponents of the Bell organization as having
invented a telephone before Bell. It was claimed that he had been too
poor to secure a patent or to bring his invention to popular notice.
Much sympathy was thus aroused for him and the legal battle was waged
to interminable length, with the usual result. Bell's patent was again
sustained, and Drawbaugh's claims were pronounced without merit.

Many other legal battles followed, but the dominance of the Bell
organization, resting upon the indisputable fact that Bell was the
first man to conceive and execute a practical telephone, could not
be shaken. The telephone business was on a firm footing: it had
demonstrated its real service to the public; it had become a
necessity; and, under the able leadership of Vail, was fast extending
its field of usefulness.



    The First Suggestion--Morse Sends Messages Through the
    Water--Trowbridge Telegraphs Through the Earth--Experiments of
    Preece and Heaviside in England--Edison Telegraphs from Moving
    Trains--Researches of Hertz Disclose the Hertzian Waves.

Great as are the possibilities of the telegraph and the telephone in
the service of man, these instruments are still limited to the wires
over which they must operate. Communication was not possible until
wires had been strung; where wires could not be strung communication
was impossible. Much yet remained to be done before perfection
in communication was attained, and, though the public generally
considered the telegraph, and the telephone the final achievement, men
of science were already searching for an even better way.

The first suggestion that electric currents carrying messages might
some day travel without wires seems to have come from K.A. Steinheil,
of Munich. In 1838 he discovered that if the two ends of a single wire
carrying the electric current be connected with the ground a complete
circuit is formed, the earth acting as the return. Thus he was able
to dispense with one wire, and he suggested that some day it might be
possible to eliminate the wire altogether. The fact that the current
bearing messages could be sent through the water was demonstrated by
Morse as early as 1842. He placed plates at the termini of a circuit
and submerged them in water some distance apart on one side of a
canal. Other plates were placed on the opposite side of the waterway
and were connected by a wire with a sensitive galvanometer in series
to act as a receiver. Currents sent from the opposite side were
recorded by the galvanometer and the possibility of communication
through the water was established. Others carried these experiments
further, it being even suggested that messages might be sent across
the Atlantic by this method.

But Bell's greatest contribution to the search for wireless telegraphy
was not his direct work in this field, but the telephone itself.
His telephone receiver provided the wireless experimenters with an
instrument of extreme sensitiveness by which they were able to detect
currents which the mirror galvanometer could not receive. While
experimenting with a telephone along a telegraph line a curious
phenomenon was noticed. The telephone experimenters heard music very
clearly. They investigated and found that another telegraph wire,
strung along the same poles, but at the usual distance and with
the usual insulation, was being used for a test of Edison's musical
telephone. Many other similar tests were made and the effect was
always noted. In some way the message on one line had been conveyed
across the air-gap and had been recorded by the telephones on the
other line. It was decided that this had been caused by induction.

Prof. John Trowbridge, of Harvard University, might well be termed
the grandfather of wireless telegraphy. He made the first extensive
investigation of the subject, and his experiments in sending
messages without wires and his discoveries furnished information and
inspiration for those who were to follow. His early experiments tested
the possibility of using the earth as a conductor. He demonstrated
that when an electric current is sent into the earth it spreads from
that point in waves in all directions, just as when a stone is cast
into a pond the ripples widen out from that point, becoming fainter
and fainter until they reach the shore. He further found that these
currents could be detected by grounding the terminals of a telephone
circuit. Telegraphy through the earth was thus possible. However, the
farther the receiving station was from the sending station the wider
must be the distance between the telephone terminals and the smaller
the current received. Professor Trowbridge did not find it possible to
operate his system at a sufficient distance to make it of value, but
he did demonstrate that the currents do travel through the earth and
that they can be set to carrying messages.

Professor Trowbridge also revived the idea of telegraphing across the
Atlantic by utilizing the conductivity of the sea-water to carry the
currents. In working out the plan theoretically he discovered that the
terminals on the American side would have to be widely separated--one
in Nova Scotia and the other in Florida--and that they would have to
be connected by an insulated cable. Two widely separated points on
the coast of France were suggested for the other terminals. He
also calculated that very high voltages would be necessary, and the
practical difficulties involved made it seem certain that such a
system would cost far too much to construct and to operate to be

Trowbridge suggested the possibility of using such a system
for establishing communication between ships at sea. Ship could
communicate with ship, over short distances, during a fog. A trailing
wire was to be used to increase the sending and receiving power, and
Trowbridge believed that with a dynamo capable of supplying current
for a hundred lights, communication could be established at a distance
of half a mile.

Not satisfied with the earth or the sea as a medium for carrying the
current, Trowbridge essayed to use the air. He believed that this was
possible, and that it would be accomplished at no distant date. He
believed, however, that such a system could not be operated over
considerable distances because of the curvature of the earth. He
endeavored to establish communication through the air by induction.
He demonstrated that if one coil of wire be set up and a current sent
through it, a similar coil facing it will have like currents induced
within it, which may be detected with a telephone receiver. He also
determined that the currents were strongest in the receiving coil when
it was placed in a plane parallel with the sending coil. By turning
the receiving coil about until the sound was strongest in the
telephone receiver, it was thus possible to determine the direction
from which the messages were coming. Trowbridge recognized the great
value of this feature to a ship at sea.

But these induced currents could only be detected at a distance by
the use of enormous coils. To receive at a half-mile a coil of eight
hundred feet radius would have been necessary, and this was obviously
impossible for use on shipboard. So these experiments also developed
no practical improvement in the existing means of communication. But
Professor Trowbridge had demonstrated new possibilities, and had set
men thinking along new lines. He was the pioneer who pointed the way
to a great invention, though he himself failed to attain it.

Bell followed up Trowbridge's suggestions of using the water as a
medium of communication, and in a series of experiments conducted on
the Potomac River established communication between moving ships.

Professor Dolbear also turned from telephone experimentation to the
search for the wireless. He grounded his wires and sent high currents
into the earth, but improved his system and took another step toward
the final achievement by adding a large induction coil to his sending
equipment. He suggested that the spoken word might be sent as well as
dots and dashes, and so sought the wireless telephone as well as
the wireless telegraph. Like his predecessors, his experiments were
successful only at short distances.

The next application of the induction telegraph was to establish
communication with moving trains. Several experimenters had suggested
it, but it remained for Thomas A. Edison to actually accomplish it.
He set up a plate of tin-foil on the engine or cars, opposite the
telegraph wires. Currents could be induced across the gap, no matter
what the speed of the train, and, traveling along the wires to the
station, communication was thus established. Had Edison continued his
investigation further, instead of turning to other pursuits, he
might have achieved the means of communicating through the air at
considerable distances.

These experiments by Americans in the early 'eighties seemed to
promise that America was to produce the wireless telegraph, as it had
produced the telegraph and the telephone. But the greatest activity
now shifted to Europe and the American men of science failed to push
their researches to a successful conclusion. Sir W.H. Preece,
an Englishman, brought himself to public notice by establishing
communication with the Isle of Wight by Morse's method. Messages were
sent and received during a period when the cable to the island was
out of commission, and thus telegraphing without wires was put to
practical use.

Preece carried his experiments much further. In 1885 he laid out two
great squares of insulated wire, a quarter of a mile to the side,
and at a distance of a quarter of a mile from each other. Telephonic
communication was established between them, and thus he had attained
wireless telephony by induction. In 1887, another Englishman, A.W.
Heaviside, laid circuits over two miles long on the surface and other
circuits in the galleries of a coal-mine three hundred and fifty feet
below, and established communication between the circuits. Working
together, Preece and Heaviside extended the distances over which
they could communicate. Preece finally decided that a combination of
conduction and induction was the best means of wireless communication.
He grounded the wire of his circuit at two points and raised it to a
considerable height between these points. Preece's work was to put the
theories of Professor Trowbridge to practical use and thus bring the
final achievement a step nearer.

But conduction and induction combined would not carry messages to a
distance that would enable extensive communication. A new medium had
yet to be found, and this was the work of Heinrich Hertz, a young
German scientist. He was experimenting with two flat coils of wire,
as had many others before him, but one of the coils had a small gap
in it. Passing the discharge from a condenser into this coil, Hertz
discovered that the spark caused when the current jumped the gap set
up electrical vibrations that excited powerful currents in the other
coil. These currents were noticeable, though the coils were a very
considerable distance apart. Thus Hertz had found out how to send out
electrical waves that would travel to a considerable distance.

What was the medium that carried these waves? This was the question
that Hertz asked himself, and the answer was, the ether. We know that
light will pass through a vacuum, and these electric waves would do
likewise. It was evident that they did not pass through the air. The
answer, as evolved by Hertz and approved by other scientists, is that
they travel through the ether, a strange substance which pervades all
space. Hertz discovered that light and his electrical waves traveled
at the same speed, and so deduced that light consists of electrical
vibrations in the ether.

With the knowledge that this all-pervading ether would carry electric
waves at the speed of light, that the waves could be set up by the
discharge of a spark across a spark-gap in a coil, and that they
could be received in another coil in resonance with the first, the
establishment of a practical wireless telegraph was not far away.

    Detectors--Marconi Seeks an Efficient Detector--Devises New Sending
    Methods--The Wireless Telegraph Takes Form--Experimental Success.

With the nineteenth century approaching its close, man had discovered
that the electric waves would travel through the ether; he had learned
something of how to propagate those waves, and something of how
to receive them. But no one had yet been able to combine these
discoveries in practical form, to apply them to the task of carrying
messages, to make the improvements necessary to make them available
for use at considerable distances. Though many mature scientists had
devoted themselves to the problem, it remained for a youth to solve
it. The youth was Guglielmo Marconi, an Italian.

We have noticed that the telegraph, the cable, and the telephone were
the work of those of the Anglo-Saxon race--Englishmen or Americans--so
it came as a distinct surprise that an Italian youth should make
the next great application of electricity to communication. But
Anglo-Saxon blood flows in Marconi's veins. Though his father was an
Italian, his mother was an Irishwoman. He was born at Villa Griffone
near Bologna, Italy, on April 25, 1874. He studied in the schools of
Bologna and of Florence, and early showed his interest in scientific
affairs. From his mother he learned English, which he speaks as
fluently as he does his native tongue. As a boy he was allowed to
attend English schools for short periods, spending some time at
Bedford and at Rugby.

One of his Italian teachers was Professor Righi, who had made a close
study of the Hertzian waves, and who was himself making no small
contributions to the advancement of the science. From him young
Marconi learned of the work which had been accomplished, and of the
apparatus which was then available. Marconi was a quiet boy--almost

He did not display the aggressive energy so common with many promising
youths. But though he was quiet, he was not slothful. He entered into
his studies with a determination and an application that brought to
him great results. He was a student and a thinker. Any scientific book
or paper which came before him was eagerly devoured. It was this habit
of careful and persistent study that made it possible for Marconi to
accomplish such wonderful things at an early age.

Marconi had learned of the Hertzian waves. It occurred to him that by
their aid wireless telegraphy might be accomplished. The boy saw the
wonderful possibilities; he dreamed dreams of how these waves might
carry messages from city to city, from ship to shore, and from
continent to continent without wires. He realized his own youth and
inexperience, and it seemed certain to him that many able scientists
had had the same vision and must be struggling toward its attainment.
For a year Marconi dreamed those dreams, studying the books and papers
which would tell him more of these wonderful waves. Each week he
expected the news that wireless telegraphy had been established, but
the news never came. Finally he concluded that others, despite their
greater opportunities, had not been so far-seeing as he had thought.

Marconi attacked the problem himself with the dogged persistence and
the studious care so characteristic of him. He began his experiments
upon his father's farm, the elder Marconi encouraging the youth and
providing him with funds with which to purchase apparatus. He set
up poles at the opposite sides of the garden and on them mounted the
simple sending and receiving instruments which were then available,
using plates of tin for his aerials. He set up a simple spark-gap, as
had Hertz, and used a receiving device little more elaborate. A Morse
telegraph-key was placed in circuit with the spark-gap. When the key
was held down for a longer period a long spark passed between the
brass knobs of the spark-gap and a dash was thus transmitted. When
the key was depressed for a shorter period a dot in the Morse code was
sent forth. After much work and adjustment Marconi was able to send
a message across the garden. Others had accomplished this for similar
distances, but they lacked Marconi's imagination and persistence, and
failed to carry their experiments further. To the young Irish-Italian
this was but a starting-point.

Marconi quickly found that the receiver was the least effective part
of the existing apparatus. The waves spread in all directions from
the sending station and become feebler and feebler as the distance
increases. To make wireless telegraphy effective over any considerable
distance a highly efficient and extremely sensitive receiving device
is necessary. Some special means of detecting the feeble currents was
necessary. The coherer was the solution. As early as 1870 a Mr. S.A.
Varley, an Englishman, had discovered that when he endeavored to
send a current through a mass of carbon granules the tiny particles
arranged themselves in order under the influence of the electric
current, and offered a free path for the passage of the current. When
shaken apart they again resisted the flow of current until it became
powerful enough to cause them to again arrange themselves into a
sort of bridge for its passage. Thus was the principle of the coherer

An Italian scientist, Professor Calzecchi-Onesti, carried these
experiments still further. He used various substances in place of the
carbon granules and showed that some of them will arrange themselves
so as to allow the passage of a current under the influence of the
spark setting up the Hertzian waves. Professor E. Branly, of the
Catholic University of Paris, took up this work in 1890. He arranged
metal filings in a small glass tube six inches long and arranged a
tapper to disarrange the filings after they had been brought together
under the influence of the spark.

With the Branly coherer as the basis Marconi sought to make
improvements which would result in the detector he was seeking. For
his powder he used nickel, mixed with a small proportion of fine
silver filings. This he placed between silver plugs in a small glass
tube. Platinum wires were connected to the silver plugs and brought
out at the opposite ends of the tube. It required long study to
determine just how to adjust the plugs between which the powder was
loosely arranged. If the particles were pressed together too tightly
they would not fall apart readily enough under the influence of the
tapper. If too much space was allowed they would not cohere readily
enough. Marconi also discovered that a larger proportion of silver
in the powder and a smaller amount between the plugs increased the
sensitiveness of the receiver. Yet he found it well not to have it
too sensitive lest it cohere for every stray current and so give false

Under the influence of the electric waves set up from the spark-gap
those tiny particles so arranged themselves that they would readily
carry a current between the plugs. By placing these plugs with their
platinum terminals in circuit with a local battery the current from
this local battery was given a passage through the coherer by the
action of the electric waves coming through the ether. While these
waves themselves were too feeble to operate a receiving mechanism,
they were strong enough to arrange the particles of the sensitive
metal in the tube in order, so that the current from the local battery
could pass through them. This current operated a telegraph relay which
in turn operated a Morse receiving instrument. An electrical tapper
was also arranged in this circuit so that it would strike the tube a
light blow after each long or short wave representing a dot or a dash
had been received. Thus the particles were disarranged, ready to array
themselves when the next wave came through the ether and so form the
bridge over which the stronger local circuit could convey the signal.

Marconi further discovered that the most effective arrangement was to
run a wire from one terminal of the coherer into the ground, and from
the other to an elevated metal plate or wire. The waves coming through
the ether were received by the elevated wire and were conducted down
to the coherer. Experimenting with his apparatus on the posts in
the garden, he discovered that an increase in the height of the wire
greatly increased the receiving distance.

At his sending station he used the exciter of his teacher, Professor
Righi. This, too, he modified and perfected for his practical purpose.
As he used the device it consisted of two brass spheres a millimeter
apart. An envelope was provided so that the sides of the spheres
toward each other and the space between was occupied by vaseline oil
which served to keep the faces of the spheres clean and produce a more
uniform spark. Outside the two spheres, but in line with them, were
placed two smaller spheres at a distance of about two-fifths of a
centimeter. The terminals of the sending circuit were attached to
these. The secondary coil of a large induction coil was placed in
series with them, and batteries were wired in series with the primary
of the coil with a sending key to make and break the circuit. When the
key was closed a series of sparks sprang across the spark-gap, and
the waves were thus set up in the ether and carried the message to the
receiving station.

As in the case of his receiving station, Marconi found that results
were much improved when he wired his sending apparatus so that one
terminal was grounded and the other connected with an elevated wire or
aerial, which is now called the antenna. By 1896 Marconi had brought
this apparatus to a state of perfection where he could transmit
messages to a distance of several miles. This Irish-Italian youth
of twenty-two had mastered the problem which had baffled veteran
scientists and was ready to place a new wonder at the service of the

The devices which Marconi thus assembled and put to practical use had
been, in the hands of others, little more than scientific toys.
Others had studied the Hertzian waves and the methods of sending and
detecting them from a purely scientific viewpoint. Marconi had the
vision to realize the practical possibilities, and, though little
more than a boy, had assembled the whole into a workable system of
communication. He richly deserves the laurels and the rewards as the
inventor of the wireless telegraph.



    Marconi Goes to England--he Confounds the Skeptics--A Message to
    France Without Wires--The Attempt to Span the Ocean--Marconi in
    America Receives the First Message from Europe--Fame and Recognition

The time had now come for Marconi to introduce himself and his
discoveries to the attention of the world. He went to England, and
on June 2, 1896, applied for a patent on his system of wireless
telegraphy. Soon afterward his plans were submitted to the
postal-telegraph authorities. Fortunately for Marconi and for the
world, W.H. Preece was then in authority in this department. He
himself had experimented with some little success with wireless
messages. He was able enough to see the merit in Marconi's
discoveries and generous enough to give him full recognition and every

The apparatus was first set up in the General Post-office in London,
another station being located on the roof but a hundred yards away.
Though several walls intervened, the Hertzian waves traversed them
without difficulty, and messages were sent and received. Stations
were then set up on Salisbury Plain, some two miles apart, and
communication was established between them.

Though the postal-telegraph authorities received Marconi's statements
of his discoveries with open mind and put his apparatus to fair tests,
the public at large was much less tolerant. The skepticism which met
Morse and Bell faced Marconi. Men of science doubted his statements
and scoffed at his claims. The Hertzian waves might be all right to
operate scientific playthings, they thought, but they were far too
uncertain to furnish a medium for carrying messages in any practical
way. Then, as progress was made and Marconi began to prove his system,
the inevitable jealousies arose. Experimenters who might have invented
the wireless telegraph, but who did not, came forward to contest
Marconi's claims and to seek to snatch his laurels from him.

The young inventor forged steadily ahead, studying and experimenting,
devising improved apparatus, meeting the difficulties one by one
as they arose. In most of his early experiments he had used a
modification of the little tin boxes which had been set up in his
father's garden as his original aerials. Having discovered that the
height of the aerials increased the range of the stations, he covered
a large kite with tin-foil and, sending it up with a wire, used this
as an aerial. Balloons were similarly employed. He soon recognized,
however, that a practical commercial system, which should be capable
of sending and receiving messages day and night, regardless of the
weather, could not be operated with kites or balloons. The height of
masts was limited, so he sought to increase the range by increasing
the electrical power of the current sending forth the sparks from the
sending station. Here he was on the right path, and another long step
forward had been taken.

In the fall of 1897 he set up a mast on the Isle of Wight, one hundred
and twenty feet high. From the top of this was strung a single wire
and a new series of experiments was begun. Marconi had spent the
summer in Italy demonstrating his apparatus, and had established
communication between a station on the shore and a war-ship of the
Italian Navy equipped with his apparatus. He now secured a small
steamer for his experiments from his station on the Isle of Wight and
equipped it with a sixty-foot mast. Communication was maintained with
the boat day after day, regardless of weather conditions. The distance
at which communication could be maintained was steadily increased
until communication was established with the mainland.

In July of 1898 the wireless demonstrated its utility as a conveyer of
news. An enterprising Dublin newspaper desired to cover the Kingstown
regatta with the aid of the wireless. In order to do this a land
station was erected at Kingstown, and another on board a steamer which
followed the yachts. A telephone wire connected the Kingstown station
with the newspaper office, and as the messages came by wireless from
the ship they were telephoned to Dublin and published in successive
editions of the evening papers.

This feat attracted so much attention that Queen Victoria sought the
aid of the wireless for her own necessities. Her son, the Prince of
Wales, lay ill on his yacht, and the aged queen desired to keep
in constant communication with him. Marconi accordingly placed one
station on the prince's yacht and another at Osborne House, the
queen's residence. Communication was readily maintained, and one
hundred and fifty messages passed by wireless between the prince and
the royal mother.

While the electric waves bearing the messages were found to pass
through wood, stone, or earth, it was soon noticed in practical
operation that when many buildings, or a hill, or any other solid
object of size intervened between the stations the waves were
greatly retarded and the messages seriously interfered with. When the
apparatus was placed on board steel vessels it was found that any part
of the vessel coming between the stations checked the communication.
Marconi sought to avoid these difficulties by erecting high aerials at
every point, so that the waves might pass through the clear air over
solid obstructions.

Marconi's next effort was to connect France with England. He went to
France to demonstrate his apparatus to the French Government and set
up a station near Boulogne. The aerial was raised to a height of one
hundred and fifty feet. Another station was erected near Folkestone
on the English coast, across the Channel. A group of French officials
gathered in the little station near Folkestone for the test, which was
made on the 27th of March, 1899. Marconi sent the messages, which were
received by the station on the French shore without difficulty. Other
messages were received from France, and wireless communication between
the nations was an accomplished fact.

The use of the wireless for ships and lighthouses sprang into favor,
and wireless stations were established all around the British coasts
so that ships equipped with wireless might keep in communication
with the land. The British Admiralty quickly recognized the value
of wireless telegraphy to war vessels. While field telegraphs and
telephones had served the armies, the navies were still dependent upon
primitive signals, since a wire cannot be strung from ship to ship
nor from ship to shore. So the British battle-ships were equipped with
wireless apparatus and a thorough test was made. A sham battle
was held in which all of the orders were sent by wireless, and
communication was constantly maintained both between the flag-ships
and the vessels of their fleets and between the flag-ships and the
shore. Marconi's invention had again proved itself.

The wireless early demonstrated its great value as a means of saving
life at sea. Lightships off the English coast were equipped with the
wireless and were thus enabled to warn ships of impending storms,
and on several occasions the wireless was used to summon aid from the
shore when ships were sinking because of accidents near the lightship.

Following the establishment of communication with France, Marconi
increased the range of his apparatus until he was able to cover most
of eastern Europe. In one of his demonstrations he sent messages
to Italy. His ambition, however, was to send messages across the
Atlantic, and he now attacked this stupendous task. On the coast of
Cornwall, England, he began the construction of a station which should
have sufficient power to send a message to America. Instead of using
a single wire for his aerial, he erected many tall poles and strung a
number of wires from pole to pole. The comparatively feeble batteries
which had furnished the currents used in the earlier efforts were
replaced with great power-driven dynamos, and converters were used
instead of the induction coil. Thus was the great Poldhu station

Late in 1901 Marconi crossed to America to superintend the
preparations there, and that he himself might be ready to receive
the first message, should it prove possible to span the ocean. Signal
Hill, near St. John's, Newfoundland was selected as the place for the
American station. The expense of building a great aerial for the test
was too great, and so dependence was had upon kites to send the wires
aloft. For many days Marconi's assistants struggled with the great
kites in an effort to get them aloft. At last they flew, carrying the
wire to a great height. The wire was carried into a small Government
building near by in which Marconi stationed himself. At his ear was a
telephone receiver, this having been substituted for the relay and the
Morse instrument because of its far greater sensitiveness.

Marconi had instructed his operator at Poldhu to send simply the
letter "s" at an hour corresponding to 12.30 A.M. in Newfoundland.
Great was the excitement and suspense in Cornwall when the hour for
the test arrived. Forgetting that they were sleepy, the staff crowded
about the sending key, and the little building at the foot of the
ring of great masts supporting the aerial shook with the crash of the
blinding sparks as the three, dots which form the letter "s" were sent
forth. Even greater was the tension on the Newfoundland coast, where
Marconi sat eagerly waiting for the signal. Finally it came, three
faint ticks in the telephone receiver. The wireless had crossed the
Atlantic. Marconi had no sending apparatus, so that it was not until
the cable had carried the news that those in England knew that the
message had been received.

Because Marconi had never made a statement or a claim he had not been
able to prove, he had attained a reputation for veracity which made
his statement that he had received a signal across the Atlantic carry
weight with the scientists. Many, of course, were skeptical, and
insisted that the simple signal had come by chance from some ship not
far away. But the inventor pushed quietly and steadily ahead, making
arrangements to perfect the system and establish it so that it would
be of commercial use.

Marconi returned to England, but two months later set out for America
again on the liner _Philadelphia_ with improved apparatus. He kept in
constant communication with his station at Poldhu until the ship was
a hundred and fifty miles from shore. Beyond that point he could not
send messages, as the sending apparatus on the ship lacked sufficient
power. Messages were received, however, until the sending station
was over two thousand miles away. This seemed miraculous to those
on shipboard, but Marconi accepted it as a matter of course. He had
equipped the Poldhu station to send twenty-one hundred miles, and he
knew that it should accomplish the feat.

A large station was set up at Cape Breton, Nova Scotia, and regular
communication was established between there and Poldhu. With the
establishment of regular transatlantic communication the utility of
Marconi's invention, even for work at great distances, was no longer
open to question. By quiet, unassuming, conscientious work he had put
another great carrier of messages at the service of the world, and he
now reaped the fame and fortune which he so richly deserved.



    Marconi Organized Wireless Telegraphy Commercially--The New Wonder
    at the Service of the World--Marine Disasters Prevented--The
    Extension of the Wireless on Shipboard--Improved Apparatus--The
    Wireless in the World War--The Boy and the Wireless.

With his clear understanding of the possibilities of his invention,
Marconi was not long in establishing the wireless upon a commercial
basis. He is a man of keen business judgment, and as he brought his
invention forward and clearly demonstrated its worth at a time when
commercial enterprise was alert he found no great difficulty in
establishing his company. The first Marconi company was organized
as early as 1897 under the name of the Wireless Telegraph and Signal
Company, Limited. This was later displaced by the Marconi Telegraph
Company, which operates a regular system of stations on a commercial
basis, carrying messages in competition with the cable and telegraph
companies. It also erects stations for other companies which are
operated under the Marconi patents.

With the telegraph and the telephone so well established and serving
the needs of ordinary communication on land, it was natural that the
wireless should make headway but slowly as a commercial proposition
between points on land. For communication at sea, however, it had no
competition, and merchant-ships as well as war vessels were rapidly
equipped with wireless apparatus.

When the great liner _Republic_ was sinking as a result of a collision
off the port of New York in 1903 her wireless brought aid. Her
passengers and crew were taken off in safety, and what otherwise would
have been a terrible disaster was avoided by the use of the wireless.
The utility of the wireless was again brought sharply to the attention
of the world. It was realized that a wireless set on a passenger-ship
was necessary if the lives of the passengers were to be safeguarded.
The United States Government by its laws now requires that
passenger-ships shall be equipped with wireless apparatus in charge of
a competent operator.

One of the early objections made to the wireless was its apparent lack
of secrecy, since any other receiving apparatus within range of the
waves sent forth by the sending station can receive the signals. It
was also realized that as soon as any considerable number of stations
were established about the world, and began sending messages to and
fro, there would be a perfect jumble of waves flying about in all
directions through the ether, so that no messages could be sent or

Marconi's answer to these difficulties was the tuning apparatus. The
electric waves carrying the messages may be sent out at widely varying
lengths. Marconi found that it was possible to adjust a receiving
station so that it would receive only waves of a certain length.
Thus stations which desired to communicate could select a certain
wave-length, and they could send and receive messages without
interfering with others using different wave-lengths, or without the
receiving station being confused by messages coming in from
other stations using different wave-lengths. You know that when a
tuning-fork is set in vibration another of the same pitch near it will
vibrate with it, but others of different pitch will not be affected.
The operation of wireless stations in tune with each other is similar.


The camera was exposed for two hours, and the white bars show the
sparks leaving the wires for their journey through the air for
seventeen hundred miles.]


These dynamos send a message straight across the ocean.]

An example of the value of tuning is afforded by the manner in which
press reports are sent from the great Marconi station at Poldhu. Each
night at a certain hour this station sends out news reports of the
events of the day, using a certain set wave-length. Each ship on the
Atlantic and every land station within range which is to receive the
reports at that hour adjusts its receiving set to receive waves of
that length. In this way they hear nothing but the Poldhu news reports
which they desire to receive, and are not troubled by messages from
other stations within range.

Secrecy is also attained by the use of tuning. It is possible that
another station may discover the wave-length being used for a secret
message and "listen in," but there are so many possible wave-lengths
that this is difficult. Secrecy may also be secured by the use of code

Many of the advantages of tuning were lost by the international
agreement which provided that but two wave-lengths should be used for
commercial work. This, however, enables ships to get in touch with
other ships in time of need. With his telephone receivers the operator
can hear the passage of the waves as they are brought to him by his
aerial and the dots and dashes sound as buzzes of greater or less
length. Out of the confusion of currents passing through the air he
can select the messages he wishes to read by sound.

You may wonder how one wireless operator gets into communication with
another. He first listens in to determine whether messages are coming
through the ether within range in the wave-length he is to use.
Hearing nothing, he adjusts his sending apparatus to the desired
wave-length and switches this in with the signal aerial which
serves both his sending and his receiving set. This at the same time
disconnects his receiving set. He sends out the call letters of the
station to which he wishes to send a message, following them with
his own call letters, as a signature to show who is calling. After
repeating these signals several times he switches out his sending set
and listens in with his receiving set. If he then gets an answer from
the other station he can begin sending the message.

Marconi was not allowed to hold the wireless field unmolested.
Many others set up wireless stations, some of them infringing upon
Marconi's patents. Others have devised wireless systems along
more original lines. Particularly we should mention two American
experimenters, Dr. de Forest and Professor Fessenden. Both have
established wireless systems with no little promise. The system of
Professor Fessenden is especially unique and original and may be
destined to work a revolution in the methods of wireless telegraphy.

With an increase in the number of wireless stations and varieties
of apparatus came a wide increase in the uses to which wireless
telegraphy was applied. We have already noticed the press service
from Poldhu. The British Government makes use of this same station to
furnish daily news to its representatives in all parts of the
world. The wireless is also used to transmit the time from the great

Some of the railroads in the United States have equipped their trails
as well as their stations with wireless sets. It has proved its worth
in communicating between stations, taking the place in time of need
of either the telegraph or the telephone. In equipping the trains with
sets a difficulty was met in arranging the aerials. It is, of course,
impossible to arrange the wires at any height above the cars, since
they would be swept away in passing under bridges. Even with very low
aerials, however, communication has been successfully maintained at
a distance of over a hundred miles. The speed of the fastest train
affects the sending and receiving of messages not at all. It was also
found that messages passed without hindrance, even though the train
was passing through a tunnel.

Another interesting application of wireless telegraphy is to the
needs of the fire-fighters. Fire stations in New York City have been
equipped with wireless telegraph sets, and they have proved so useful
in spreading alarms and transmitting news of fires that they seem
destined to come into universal use.

The outbreak of the world war gave a tremendous impetus to the
development of wireless telegraphy. The German cable to the United
States was cut in the early days of the conflict. The sending power
of wireless stations had been sufficiently increased, however, so that
the great German stations could communicate with those in the United
States. Communication was readily maintained between the Allies by
means of wireless, the great stations at Poldhu and at the Eiffel
Tower in Paris being in constant communication with each other and
with the stations in Italy and in Russia.

Portable field sets had been used with some slight success even in the
Boer War, and had definitely proved their worth in the Balkans. The
outbreak of the greater war found all of the nations equipped with
portable apparatus for the use of their armies. These proved of
great use. The field sets of the United States Army also proved their
utility in the campaign into Mexico in pursuit of Villa. By their
means it was possible for General Pershing's forces to keep in
constant touch with the headquarters in the United States.

The wireless proved as valuable to the navies as had been anticipated.
The Germans in particular made great improvements in light wireless
sets designed for use on aircraft. The problem of placing an aerial on
an aeroplane is difficult, but no little headway has been made in this

It is the American boy who has done the most interesting work with the
wireless in the United States. While the commercial development
has been comparatively slow, the boys have set up stations by the
thousands. Most of these stations were constructed by the boys
themselves, who have learned and are learning how best to apply this
modern wonder to the service of man. So many amateurs set up stations
that the Government found it necessary to regulate them by law.
The law now requires that amateur experimenters use only short
wave-lengths in their sending, which will not interfere with messages
from Government or commercial stations. It also provides for the
licensing of amateurs who prove competent.

The stations owned and operated by boys have already proved of great
use. In times of storm and flood when wire communication failed they
have proved the only means of communicating with many districts. In
time of war these amateur stations, scattered in all parts of the
country, might prove immensely valuable. Means have now been taken to
so organize the amateurs that they can communicate with one another,
and by this means messages may be sent to any part of the country.

One young American, John Hays Hammond, Jr., has applied the wireless
in novel and interesting ways. By means of special apparatus mounted
on a small boat he can by the means of a wireless station on shore
start or stop the vessel, or steer it in any direction by his wireless
control. He has applied the same system to the control of torpedoes.
By this means a torpedo may be controlled after it has left the shore
and may be directed in any direction as long as it is within sight.
This invention may prove of incalculable benefit should America be
attacked by a foreign power.

What startling developments of wireless telegraphy lie still in the
future we do not know. Marconi has predicted that wireless messages
will circle the globe. "I believe," he has said, "that in the near
future a wireless message will be sent from New York completely around
the world without relaying, and will be received by an instrument
in the same office with the transmitter, in perhaps less time than
Shakespeare's forty minutes."

Not long ago the United States battle-ship _Wyoming_, lying off Cape
Henry on the Atlantic coast, communicated with the _San Diego_ at
Guaymas, on the Pacific coast of Mexico. This distance, twenty-five
hundred miles across land, shows that Marconi's prediction may be
realized in the not distant future.

It seemed to many that the wireless telegraph was to be the final word
in the development of communication, but two striking achievements
coming in 1915 proved this to be far from the case. While one group of
scientists had given themselves to experimentation with the Hertzian
waves which led to wireless telegraphy, other scientists and engineers
were busily engaged in bringing the telephone to a perfection
which would enable it to accomplish even more striking feats. These
electrical pioneers did not work as individuals, but were grouped
together as the engineering staff of the American Telephone and
Telegraph Company. At their head was John J. Carty, and it was under
his guiding genius that the great work was accomplished. John Carty
is the American son of Irish parents. He was born in Cambridge,
Massachusetts, on April 14, 1861. His father was a gun-maker and an
expert mechanic of marked intelligence and ingenuity who numbered
among his friends Howe, the creator of the sewing-machine. As a boy
John Carty displayed the liveliest interest in things electrical. When
the time came for him to go to school, physics was his favorite study.
He showed himself to be possessed of a keen mind and an infinite
capacity for work. To these advantages was added a good elementary
education. He was graduated from Cambridge Latin School, where he
prepared for Harvard University. Before he could enter the university
his eyesight failed, and the doctor forbade continuance of study.
Many a boy would have been discouraged by this physical handicap which
denied him complete scholastic preparation. But this boy was not
the kind that gives up. He had been supplementing his school work
in physics with experimentations upon his own behalf. Let us let Mr.
Carty tell in his own words how he next occupied himself.

    I had often visited the shop of Thomas Hall, at 19 Bromfield
    Street, and looked in the window. I went in from time to time,
    not to make large purchases, but mostly to make inquiries and
    to buy some blue vitriol, wire, or something of the kind. It
    was a store where apparatus was sold for experimentation in
    schools, and on Saturdays a number of Harvard and Institute
    of Technology professors could be found there. It was quite a
    rendezvous for the scientific men in those days, just the
    same as the Old Corner Bookstore at the corner of School and
    Washington Streets was a place where the literary men used to
    congregate. Don't think that I was an associate of these great
    scientists, but I was very much attracted to the atmosphere of
    that store. I wanted to get in and handle the apparatus.

    Finally it occurred to me that I would like to get into the
    business, somehow. But I did not have the courage to go in
    and ask them for a job. One day I was going by and saw a sign
    hanging out, "Boy Wanted." I was about nineteen, and really
    thought I was something of a scientist, not exactly a boy. I
    was a boy, however. I walked by on one side of the street and
    then on the other, looking in, and finally the idea possessed
    me to go in and strike for that job. So I took down the sign,
    which was outside the window, put it under my arm, and went in
    and persuaded Tom Hall that I was the boy he wanted.

    He said, "When can you begin?" I said, "Now." There was no
    talk of wages or duties. He said, "Take this package around
    to Earle & Prew's express and hurry back, as I have another
    errand for you to do." So I had to take a great, heavy box
    around to the express-office and get a receipt for it. I
    found, when Saturday night came around, that I had been
    engaged at the rate of fifty cents a day. I would have been
    glad to work for nothing.

    Well, I did not get near that apparatus in a hurry, not until
    the time came for fixing up the window. My first talk in
    regard to it had no reference to services in a scientific
    capacity on my part. I had rather hoped that the boss would
    come around and consult with, me as to how to adjust the
    apparatus. But that was not it. He said: "John, clean out that
    window. Everything is full of dust, and be careful and don't
    break anything!" So I cleaned it out. I swept out the place,
    cleaned about there, did errands, mixed battery solutions, and
    got a great deal of experience there in one way or another. I
    did whatever there was to do and got a good deal of fun out
    of it, while becoming acquainted with the state of the art of
    that day. I got to know intimately all the different sorts of
    philosophical apparatus there were, and how to mix the various
    battery solutions. In fact, I became really quite experienced
    for those times in such matters.

It was not long before young Carty lost his job. Being a regular boy,
he had been guilty of too much skylarking. This experience steadied
him, and he forthwith sought a new job. He had met some of the
employees of the telephone company and was naturally interested in
their work. At that time "hello boys" held sway in the crude telephone
exchanges, the "hello girl" having not yet appeared. So John Carty at
the age of nineteen went to work in the Boston telephone exchange.

The switchboard at which they placed him had been good enough for
the other boys who had been called upon to operate it, and indeed
it represented the best thought and effort of the leaders in the
telephone world. But it did not satisfy Carty, who, not content
with simply-operating the board, studied its construction and began
planning improvements. As Mr. Carty himself puts it:

    The little switchboards of that day were a good deal like the
    automobiles of some years ago--one was likely to spend more
    time under the switchboard than, sitting at it! In that way I
    learned a great deal about the arrangement and construction
    of switchboards. Encountering the trouble first, I had an
    advantage over others in being able to suggest a remedy. So I
    have always thought it was a good thing to have troubles, as
    long as they are not too serious or too numerous. Troubles are
    certainly a great advantage, if we manage them correctly.

Certainly Carty made these switchboard troubles the first
stepping-stone in his climb to the top in the field of telephone
engineering. The improvements which the youngster suggested were so
valuable that they were soon being made under his direction, and
ere long he installed in the Boston exchange the first multiple
switchboard, the fundamental features of which are in the switchboards
of to-day. In his work with the switchboards young Carty early got
in touch with Charles E. Scribner, another youngster who was doing
notable work in this field. The young men became fast friends and
worked much together. Scribner devoted himself almost exclusively
to switchboards and came to be known as the father of the modern

Boston had her peculiar problems and an "express" service was needed.
How to handle this in the exchange was another problem, and this, too,
Carty solved. For this purpose he designed and installed the first
metallic circuit, multiple switchboard to go into service. The
problems of the exchange were among the most serious of the many which
troubled the early telephone companies. Of course every telephone-user
desired to be able to converse with any other who had a telephone in
his office or residence. The development of the switchboards had been
comparatively slow in the past, and the service rendered by the boys
proved far from satisfactory. The average boy proved himself
too little amenable to discipline, too inclined to "sass" the
telephone-users, and too careless. But the early use of "hello boys"
was at least a success for the telephone in that it brought to
its service John J. Carty. This boy pointed the way to the great
improvements that made it possible to handle the constantly growing
volume of calls expeditiously and effectively.

The early telephones were operated with a single wire grounded at
either end, the earth return being used to complete the circuit
as with the telegraph. But while the currents used to operate the
telegraph are fairly strong and so can dominate the earth currents,
the tiny currents which represented the vibrations of the human voice
were all too often drowned by the earth currents which strayed on to
the lines. Telephone engineers were not then agreed that this caused
the difficulty; but they did know there was difficulty. Many weird
noises played over the lines and as often as not the spoken word was
twisted into the strangest gibberish and rendered unintelligible. If
the telephone was to satisfy its patrons and prove of real service
to the world, the difficulty had to be overcome. Some of the more
progressive engineers insisted that a double-wire system without a
ground was necessary. This, of course, involved tremendous expenses
in rebuilding every line and duplicating every wire. The more
conservative hesitated, but Carty forged ahead.

In 1880 he was engaged in operating a new line out of Boston. He was
convinced that the double-wire system alone could be successful, and
he arranged to operate a line on this plan. Taking two single lines,
he instructed the operator at the other end to join them, forming a
two-wire circuit. The results justified him. At last a line had been
attained which could be depended upon to carry the conversation.

No sooner was one problem solved than another presented itself. What
to do with the constantly increasing number of wires was a pressing
difficulty. All telephone circuits had been strung overhead, and with
the demand for telephones for office and residence rapidly increasing,
the streets of the great cities were becoming a perfect forest of
telephone poles, with the sky obscured by a maze of wires. Poles were
constantly increased in height until a line was strung along Wall
Street in New York City at a height of ninety feet. From the poles the
wires overflowed to the housetops, increasing the difficulty of the
engineers. How to protect the wires so that they could be placed
underground was the problem.

We have noticed that Theodore Vail had been brought to the head of
the Bell system in its infancy and had led the fight against the rival
companies until it was thoroughly established. Now he was directing
his genius and executive ability to so improving the telephone that
it should serve every need of communication. While the engineers
discussed theories Vail began actual tests. A trench five miles long
was dug beside a railway track by the simple expedient of hitching a
plow to a locomotive. In this trench were laid a number of wires, each
with a different covering. The gutta-percha and the rubber coverings
which had been used in cable construction predominated. It was found
that these wires would carry the telephone currents, not as well as
might be desired, but well enough to assure Vail that he was on the
right track. The companies began to place their wires underground, and
Vail saw to it that the experiments with coverings for telephone wires
were continued. The result was the successful underground cables in
use to-day.

At the same time Vail and his engineers were seeking to improve the
wires themselves. Iron and steel wires had been used, but they proved
unsatisfactory, as they rusted and were poor conductors. Copper was
an excellent conductor, but the metal in the pure state is soft and
no one then knew how to make a copper wire that would sustain its own
weight. But Vail kept his men at the problem and the hard-drawn copper
wire was at length evolved. This proved just what was needed for the
telephone circuits. The copper wire was four times as expensive as the
iron, but as it was four times as good Vail adopted it.

John Carty had rather more than kept pace with these improvements. He
was but twenty-six years of age when Union N. Bethell, head of the New
York company, picked Carty to take charge of the telephone engineering
work in the metropolis. Bethell was Vail's chief executive officer,
and under him Carty received an invaluable training in executive work.
Carty's largest task was putting the wires underground, and here again
he was a tremendous success. He found ways to make cables cheaper
and better, and devised means of laying them at half the former cost.
Having solved the most pressing problems in this field, his employers,
who had come to recognize his marked genius, set him to work again on
the switchboard. He was placed in charge of the switchboard department
of the Western Electric Company, the concern which manufactures the
apparatus for the telephone company. The switchboard, as we have
seen, was Carty's first love, and again he pointed the way to great
improvements. Most of the large switchboards of that time were
installed under his direction, and they were better switchboards than
had ever been known before.

Up to this time it had been thought necessary to have individual
batteries supplying current to each line. These were a constant source
of difficulty, and Carty directed his own attention, and that of his
associate engineers, to finding a satisfactory solution. He sought a
method of utilizing one common battery at the central station and the
way was found and the improvement accomplished.

Though the telephone circuits were now protected from the earth,
telephone-users, at times when the lines were busy, were still
troubled with roarings and strange cross-talk. Though busy with the
many engineering problems which the telephone heads had assigned to
him, Carty found time for some original research. He showed that the
roarings in the wires were largely caused by electro-static induction.
In 1889 he read a paper before the Electric Club that startled the
engineers of that day. He demonstrated that in every telephone circuit
there is a particular point at which, if a telephone is inserted, no
cross-talk can be heard. He had worked out the rules for determining
this point. Thus he had at once discovered the trouble and prescribed
the cure. Of course it could not be expected that the sage experts
would all agree with young Carty right away; but they were forced to
in the end, for again he was proved right.

By 1901 Carty was ready with another invention which was to place the
telephone in the homes of hundreds of thousands who, without it, could
scarcely have afforded this modern necessity. This was the "bridging
bell" which made possible the party line. By its use four telephones
could be placed on a single line, each with its own signal, so that
any one could be rung without ringing the others. Its introduction
inaugurated a new boom in the use of the telephone.

Theodore Vail had resigned from his positions with the telephone
companies in 1890 with the determination to retire from business. But
when the panic of 1907 came the directors of the company went to him
on his Vermont farm and pleaded with him to return and again resume
the leadership. Other and younger men would not do in this business
crisis. They also pointed out that the nation's telephones had not
yet been molded into the national system which had been his dream--a
system of universal service in which any one at any point in the
country might talk by telephone with any other. So Vail re-entered
the telephone field and again took the presidency of the American
Telephone and Telegraph Company.

One of his first official acts was to appoint John J. Carty his chief
engineer. Vail had selected the right man to make his dreams come
true; Carty now had the executive who would make it possible for
him to accomplish even larger things. He set about building up the
engineering organization which was to accomplish the work, selecting
the most brilliant graduates of American technical schools. He set
this organization to work upon the extension and development of the
long-distance telephone lines.

As a "hello boy" Carty had believed in the possibility of the
long-distance telephone when others had scoffed. He has told of an
early experience while in the Boston exchange:

    One hot day an old lady toiled up the inevitable flights of
    stairs which led to the telephone-office of those times.
    Out of breath, she sat down, and when she had recovered
    sufficiently to speak she said she wanted to talk to Chicago.
    My colleagues of that time were all what the ethnologists
    would rank a little bit lower than the wild Indian. These
    youngsters set up a great laugh; and, indeed, the absurdity of
    the old lady's project could hardly be overstated, because
    at that time Salem was a long-distance line, Lowell sometimes
    worked, and Worcester was the limit--that is, in every sense
    of the word. The Lowell line was so unreliable that we had a
    telegraph operator there, and when the talk was not possible,
    he pushed the message through by Morse. It is no wonder that
    the absurdity of the old lady's proposal was the cause
    of poorly suppressed merriment. But I can remember that I
    explained to her that our wires had not yet been extended to
    Chicago, and that, after she had departed, I turned to the
    other operators and said that the day would come when we could
    talk to Chicago. My prophecy was received with what might
    be called--putting it mildly--vociferous discourtesy.
    Nevertheless, I remember very well the impression which that
    old lady's request made upon me; and I really did believe
    that, some day or other, in some way, we would be able to talk
    to Chicago.

By 1912 it was possible to talk from New York to Denver, a distance of
2,100 miles. No European engineers had achieved any such results, and
this feat brought to Carty and his wonderful staff the admiration
of foreign experts. But for the American engineers this was only a

The next step was to link New York and California. This was more than
a matter of setting poles and stringing wires, stupendous though this
task was. The line crosses thirteen States, and is carried on 130,000
poles. Three thousand tons of wire are used in the line. The Panama
Canal took nine years to complete, and cost over three hundred million
dollars; but within that time the telephone company spent twice that
amount in engineering construction work alone, extending the scope of
the telephone.

The technical problems were even more difficult. Carty and his
engineers had to find a way to send something three thousand
miles with the breath as its motive power. It was a problem of the
conservation of the tiny electric current which carried the speech.
The power could not be augmented or speech would not result at the

Added to the efforts of these able engineers was the work of Prof.
Michael I. Pupin, of Columbia University, whose brilliant invention
of the loading coil some ten years before had startled the scientific
world and had increased the range of telephonic transmission through
underground cables and through overhead wires far beyond what
had formerly been possible. Professor Pupin applied his masterful
knowledge of physics and his profound mathematical attainments
so successfully to the practical problems of the transmission of
telephone speech that he has been called "the telephone scientist."
It is impossible to talk over long-distance lines anywhere in America
without speaking through Pupin coils, which are distributed throughout
the hundreds of thousands of miles of wire covering the North American
continent. In the transcontinental telephone line Pupin coils play a
most important part, and they are distributed at eight-mile intervals
throughout its entire length from the Atlantic to the Pacific. In
speaking at a dinner of eminent scientists, Mr. Carty once said that
on account of his distinguished scientific attainments and wonderful
telephonic inventions, Professor Pupin would rank in history alongside
of Bell himself.

We have seen how Alexander Graham Bell, standing in the little room in
Boston, spoke through the crude telephone he had constructed the first
words ever carried over a wire, and how these words were heard and
understood by his associate, Thomas Watson. This was in 1876, and it
was in January of 1915--less than forty years later--that these
two men talked across the continent. The transcontinental line was
complete. Bell in the offices of the company in New York talked freely
with Watson in San Francisco, and all in the most conversational
tone, without a trace of the difficulty that had attended their first
conversation over the short line. Thus, within the span of a single
life the telephone had been developed from a crude instrument which
transmitted speech with difficulty over a wire a hundred feet long,
until one could be heard perfectly, though over three thousand miles
of wire intervened.

The spoken word travels across the continent almost instantaneously,
far faster than the speed of sound. If it were possible for one to be
heard in San Francisco as he shouted from New York through the air,
four hours would be required before the sound would arrive. Thus the
telephone has been brought to a point of perfection where it carries
sound by electricity and reproduces it again far more rapidly and
efficiently than sound can be transmitted through its natural medium.



    The Search for the Wireless Telephone--Early Successes--Carty and
    His Assistants Seek the Wireless Telephone--The Task Before Them--De
    Forest's Amplifier--Experimental Success Achieved--The
    Test--Honolulu and Paris Hear Arlington--The Future.

No sooner had Marconi placed the wireless telegraph at the service of
the world than men of science of all nations began the search for
the wireless telephone. But the vibrations necessary to reproduce the
sound of the human voice are so infinitely more complex than those
which will suffice to carry signals representing the dots and
dashes of the telegraph code that the problem long defied solution.
Scientists attacked the problem with vigor, and various means of
wireless telephony were developed, without any being produced which
were effective over sufficient ranges to make them really useful.

Probably the earliest medium chosen to carry wireless speech was light
rays. A microphone transmitter was arranged so that the vibrations
of the voice would affect the stream of gas flowing in a sensitive
burner. The flame was thus thrown into vibrations corresponding to the
vibrations of sound. The rays from this flame were then directed by
mirrors to a distant receiving station and there concentrated on
a photo-electric selenium cell, which has the strange property of
varying its resistance according to the illumination. Thus a telephone
receiver arranged in series with it was made to reproduce the sounds.

This strange, wireless telephone was so arranged that a search-light
beam could be used for the light path, and distances up to three miles
were covered. Even with this limited range the search-light telephone
had certain advantages. Its message could be received only by those in
the direct line of the light. Neither did it require aerial masts
or wires and a trained telegrapher who could send and receive the
telegraph code. It was put to some use between battle-ships and
smaller craft lying within a radius of a few miles. The sensitive
selenium cell proved unreliable, however, and this means of
communication was destined to failure.

The experimenters realized that future success lay in making the ether
carry telephonic currents as it carried telegraphic currents. They
succeeded in establishing communication without wires, using the same
antenna as in wireless telegraphy, and the principles determined are
those used in the wireless telephone of to-day. The sending apparatus
was so arranged that continuous oscillations are set up in the ether,
either by a high-frequency machine or from an electric arc. Where
set up by spark discharges the spark frequency must be above twenty
thousand per second. This unbroken wave train does not affect the
telephone and is not audible in a telephone receiver inserted in the
radio receiving circuit. But when a microphone transmitter is inserted
in the sending circuit, instead of the make-and-break key used for
telegraphy, the waves of the voice, thrown against the transmitter
in speaking, break up the waves so that the telephone receiver in the
receiving circuit will reproduce sound. Here was and is the wireless
telephone. Marconi and many other scientists were able to operate
it successfully over comparatively short distances, and were busily
engaged in extending its range and improving the apparatus. One
great difficulty involved was in increasing the power of the sending
apparatus. Greater range has been secured in wireless telegraphy by
using stronger sending currents. But the delicate microphone would
not carry these stronger currents. Increased sensitiveness in the
receiving apparatus was also necessary.

Not content with their accomplishments in increasing the scope of the
wire telephone, the engineers of the Bell organization, headed by
John J. Carty, turned their attention to the wireless transmission
of speech. Determined that the existing telephone system should be
extended and supplemented in every useful way, they attacked the
problem with vigor. It was a problem that had long baffled the keenest
of European scientists, including Marconi himself, but that did not
deter Carty and his associates. They were determined that the glory of
spanning the Atlantic by wireless telephone should come to America
and American engineers. They wanted history to record the wireless
telephone as an American achievement along with the telegraph and the

The methods used in achieving the wireless telephone were widely
different from those which brought forth the telegraph and the
telephone. Times had changed. Men had found that it was more effective
to work together through organizations than to struggle along as
individuals. The very physical scope of the undertakings made the old
methods impracticable. One cannot perfect a transcontinental telephone
line nor a transatlantic wireless telephone in a garret. And with a
powerful organization behind them it was not necessary for Carty
and his associates to starve and skimp through interminable years,
handicapped by the inadequate equipment, while they slowly achieved
results. This great organization, working with modern methods,
produced the most wonderful results with startling rapidity.

Important work had already been done by Marconi, Fessenden, De Forest,
and others. But their results were still incomplete; they could not
talk for any considerable distance. Carty organized his staff with
care, Bancroft Gerhardi, Doctor Jewett, H.D. Arnold, and Colpitts
being prominent among the group of brilliant American scientists
who joined with Carty in his great undertaking. While much had
been accomplished, much still remained to be done, and the various
contributions had to be co-ordinated into a unified, workable whole.
In large part it was Carty's task to direct the work of this staff and
to see that all moved smoothly and in the right direction. Just as
the telephone was more complex than the telegraph, and the wireless
telegraph than the telephone, so the apparatus used in wireless
telephony is even more complex and technical. Working with the
intricate mechanisms and delicate apparatus, one part after another
was improved and adapted to the task at hand.

To the devices of Carty and his associates was added the extremely
delicate detector that was needed. This was the invention of Dr.
Lee de Forest, an American inventor and a graduate of the Sheffield
Technical School of Yale University. De Forest's contribution was
a lamp instrument, a three-step audion amplifier. This is to the
wireless telephone what the coherer is to the wireless telegraph. It
is so delicate that the faintest currents coming through the ether
will stimulate it and serve to set in motion local sources of
electrical energy so that the waves received are magnified to a point
where they will produce sound.

By the spring of 1915, but a few months after the transcontinental
telephone line had been put in operation, Carty had his wireless
telephone apparatus ready for extended tests. A small experimental
tower was set up at Montauk Point, Long Island, and another was
borrowed at Wilmington, Delaware. The tests were successful, and the
experimenters found that they could talk freely with each other. Soon
they talked over a thousand miles, from the tower at Montauk Point
to another at St. Simon's Island, Georgia. This in itself was a great
achievement, but the world was not told of it. "Do it first and then
talk about it" is the maxim with Theodore Vail and his telephone men.
This was but a beginning, and Carty had far more wonderful things in

It was on the 29th of September, 1915, that Carty conducted the
demonstrations which thrilled the world and showed that wireless
telephony was an accomplished fact. Sitting in his office in New York,
President Theodore Vail spoke into his desk telephone of the familiar
type. The wires carried his words to the towers of the Navy wireless
station at Arlington, Virginia, where they were delivered to the
sending apparatus of the wireless telephone. Leaping into space, they
traveled in every direction through the ether. The antenna of the
wireless station at Mare Island, California, caught part of the waves
and they were amplified so that John Carty, sitting with his ear
to the receiver, could hear the voice of his chief. Carty and his
associates had not only developed a system which made it possible to
talk across the continent without wires, but they had made it possible
to combine wire and wireless telegraphy. He and Vail talked with each
other freely and easily, while the naval officers who verified the
tests marveled.

But even more wonderful things were to come. Early in the morning of
the next day other messages were sent from the Arlington tower,
and these messages were heard by Lloyd Espenschied, one of Carty's
engineers, who was stationed at the wireless station at Pearl Harbor,
near Honolulu, Hawaii. The distance covered was nearly five thousand
miles, and half of it was across land, which is the more remarkable as
the wireless does not operate so readily over land as over water.
The distance covered in this test was greater than the distance
from Washington to London, Paris, Berlin, Vienna, or Petrograd. The
successful completion of this test meant that the capitals of the
great nations of the world might communicate, might talk with
one another, by wireless telephone. Only a receiving set had been
installed at Hawaii, so that it was not possible for Espenschied to
reply to the message from Arlington, and it was not until his message
came by cable that those at Arlington knew that the words they had
spoken had traveled five thousand miles. Other receiving sets had been
located at San Diego and at Darien on the Isthmus of Panama, and at
these points also the words were distinctly heard.

By the latter part of October all was in readiness for a transatlantic
test, and on the 20th of October American engineers, with American
apparatus installed at the great French station at the Eiffel Tower,
Paris, heard the words spoken at Arlington, Virginia. Carty and his
engineers had bridged the Atlantic for the spoken word. Because of
war-time conditions it was not possible to secure the use of the
French station for an extended test, but the fact was established that
once the apparatus is in place telephonic communication between Europe
and America may he carried on regularly.

The apparatus used as developed by the engineers of the Bell system
was in a measure an outgrowth of their work with the long-distance
telephone. Wireless telephony, despite the wonders it has already
accomplished, is still in its infancy. With more perfect apparatus
and the knowledge that comes with experience we may expect that speech
will girdle the earth.

It is natural that one should wonder whether the wireless telephone is
destined to displace our present apparatus. This does not seem at all
probable. In the first place, wireless telephony is now, and probably
always will be, very expensive. Where the wire will do it is the more
economical. There are many limitations to the use of the other for
talking purposes, and it cannot be drawn upon too strongly by the man
of science. It will accomplish miracles, but must not be overtaxed.
Millions of messages going in all directions, crossing and
recrossing one another, as is done every day by wire, are probably
an impossibility by wireless telephony. Weird and little-understood
conditions of the ether, static electricity, radio disturbances, make
wireless work uncertain, and such a thing as twenty-four-hour service,
seven days in the week, can probably never be guaranteed. In radio
communication all must use a common medium, and as its use increases,
so also do the difficulties. The privacy of the wire is also lacking
with the wireless telephone.

But because a way was found to couple the wireless telephone with the
wire telephone, the new wonder has great possibilities as a supplement
to our existing system. Before so very long it may be possible for an
American business man sitting in his office to call up and converse
with a friend on a liner crossing the Atlantic. The advantages
of speaking between ship and ship as an improvement over wireless
telegraphy in time of need are obvious. A demonstration of the part
this great national telephone system would play in the country's
defense in case of attack was held in May of 1916. The Navy Department
at Washington was placed in communication with every navy-yard and
post in the United States, so that the executive officers could
instantly talk with those in charge of the posts throughout the
country. The wireless telephone was used in addition to the long
distance, and Secretary of the Navy Daniels, sitting at his desk at
Washington, talked with Captain Chandler, who was at his station on
the bridge of the U.S.S. _New Hampshire_ at Hampton Roads.

Whatever the future limitations of wireless telephony, there is
no doubt as to the place it will take among the scientific
accomplishments of the age. Merely as a scientific discovery or
invention, it ranks among the wonders of civilization. Much as the
tremendous leap of human voice across the line from New York to San
Francisco appealed to the mind, there is something infinitely more
fascinating in this new triumph of the engineer. The human mind can
grasp the idea of the spoken word being carried along wires, though
that is difficult enough, but when we try to understand its flight
through space we are faced with something beyond the comprehension of
the layman and almost past belief.

We have seen how communication has developed, very slowly at first,
and then, as electricity was discovered, with great rapidity until man
may converse with man at a distance of five thousand miles. What
the future will bring forth we do not know. The ether may be made to
accomplish even more wonderful things as a bearer of intelligence.
Though we cannot now see how it would be possible, the day may come
when every automobile and aeroplane will be equipped with its wireless
telephone, and the motorist and aviator, wherever they go, may
talk with anyone anywhere. The transmission of power by wireless is
confidently predicted. Pictures have been transmitted by telegraph. It
may be possible to transmit them by wireless. Then some one may find
out how to transmit moving pictures through the ether. Then one might
sit and see before him on a screen a representation of what was then
happening thousands of miles away, and, listening through a telephone,
hear all the sounds at the same place. Wonders that we cannot even now
imagine may lie before us.



_By F.W. Lienan, Superintendent Tariff Bureau, Western Union Telegraph

The invention of Samuel F.B. Morse is unique in this, that the methods
and instruments of telegraph operation as he evolved them from his
first experimental apparatus were so simple, and yet so completely met
the requirements, that they have continued in use to the present day
in practically their original form. But this does not mean that there
has not been the same constant striving for betterment in this as in
every other art. Many minds have, since the birth of the telegraph,
occupied themselves with the problem of devising improved means of
telegraphic transmission. The results have varied according to the
point of view from which the subject was approached, but all, directly
or indirectly, sought the same goal (the obvious one, since speed is
the essence of telegraphy), to find the best means of sending more
messages over the wire in a given time. It will readily suggest
itself that the solution of this problem lies either in an arrangement
enabling the wire to carry more than one message at once, or in some
apparatus capable of transmitting messages over the wire more
rapidly than can be done by hand, or in a combination of both these

Duplex and quadruples operations are perhaps the most generally known
methods by which increased utilization of the capacity of the line has
been achieved. Duplex operation permits of the sending of two messages
over one wire in opposite directions at the same time; and quadruples,
the simultaneous transmission of four messages, two going in each
direction. Truly a remarkable accomplishment; but, like many other
things that have found their permanent place in daily use, become so
familiar that we no longer pause to marvel at it. These expedients
constitute a direct and very effective attack on the problem how to
get more work out of the wire with the existing means of operation,
and on account of their fundamental character and the important place
which by reason thereof they have taken in the telegraphic art, are
entitled to first mention.

The problem of increasing the rapidity of transmission has been met by
various automatic systems of telegraphy, so called because they embody
the idea of mechanical transmission with resulting gain in speed and
other advantages. The number of these which have from time to time
been devised is considerable. Not all have proven to be practicable,
but those which have failed to prove in under actual operating
conditions none the less display evidence of ingenuity which may well
excite our admiration.

To mention one or two which may be interesting on account of the
oddity of their method--there was, for instance, an early device,
similar in principle to the calling apparatus of the automatic
telephone, which involved the turning of a movable disk so that a
projection on its circumference pointed successively to the letters to
be transmitted. Experiments were made with ordinary metal type set up
in a composing-stick, a series of brushes passing over the type faces
and producing similar characters on a tape at the other end of the
line. In another more recent ingenious device a pivoted mirror at the
receiving end was so manipulated by the electrical impulses that a ray
of light reflected from the surface of the mirror actually wrote the
message upon sensitized paper, like a pencil, in a fair handwriting.
In another the receiving apparatus printed vertical, horizontal, and
slanting lines in such manner that they combined to make letters,
rather angular, it is true, but legible.

These and other kindred devices are interesting as efforts to
accomplish the direct production of legible messages. In experimental
tests they performed their function successfully, and in some cases
with considerable speed, but some of them required more than one line
wire, some were too sensitive to disturbance by inductive currents
and some developed other weaknesses which have prevented their
incorporation in the actual operating machinery of to-day.

In the general development of the so-called automatic telegraph
devices which have been or now are in practical operation, two lines
have been pursued. One involves direct keyboard transmission; the
other, the use at the sending end of a perforated tape capable of
being run through a transmitting machine at high speed. One type of
the former is the so-called step-by-step process, in which a revolving
body in the transmitting apparatus, as, for instance, a cylinder
provided with pegs placed at intervals around its circumference in
spiral fashion, is arrested by the depression of the keys of the
keyboard in such a way that a type wheel in the receiving apparatus
at the distant end of the line prints the corresponding letter.
This method was employed in the House and Phelps printing telegraphs
operated by the Western Union Telegraph Company in its earlier days,
and is to-day used in the operation of the familiar ticker. In
another type of direct keyboard operation the manipulation of the
keys transmits the impulses directly to the line and the receiving
apparatus translates them by electrically controlled mechanical
devices into printed characters in message form.

The systems best adapted to rapid telegraph work are predicated on the
use of a perforated tape on which, by means of a suitable perforating
apparatus, little round holes are produced in various groupings, each
group, when the tape is passed through the transmitter, causing a
certain combination of electrical impulses to pass over the wire.
The transmitter as a rule consists of a mechanically or motor driven
mechanism which causes the telegraph impulses to be transmitted to the
line, and the combination and character of the impulses are determined
by the tape perforations. The rapidity with which the tape may
be driven through the transmitter makes very high speed operation
possible. Of course it is necessary that there should be at the other
end of the wire apparatus capable of receiving and recording the
signals as speedily as they are sent.

As early as 1848 Alexander Bain perfected a system involving the use
of the perforated transmitting tape; at the receiving station the
messages were recorded in dots and dashes upon a chemically prepared
strip of paper by means of iron pens, the metal of which was, through
the combined action of the electrical current and the chemical
preparation, decomposed, producing black marks in the form of dots and
dashes upon the paper. The Bain apparatus was in actual operation in
the younger days of the telegraph. Various systems, based on similar
principles, involving tape transmission and the production of dots and
dashes on a receiving tape, have from time to time been devised, but
have generally not succeeded in establishing any permanent usefulness
in competition with more effective instrumentalities which have been

The hardiest survivor of them is the Wheatstone apparatus, which
has been in successful operation for years. Originally the
perforating--or, to use the commonly current term, the punching--of
the Wheatstone sending tape was accomplished by a mechanism equipped
with three keys--one for the dot, one for the dash, and one for the
space. The keys were struck with rubber-tipped mallets held in the
hands of the operator and brought down with considerable force. Later
this rather primitive perforator was supplanted by one equipped with a
full keyboard on the order of a typewriter keyboard. At the receiving
end of the line the messages are produced on a tape in dots and dashes
of the Morse alphabet, and hence a further process of translation is
necessary. This system has proven very useful, particularly in times
of wire trouble and scarcity of facilities, when it is essential to
move as many messages as possible over the available lines.

The schemes devised for combining automatic transmission by the
perforated-tape method with direct production of the message at
its destination in ordinary letters and figures, eliminating the
intervening step of translation from Morse characters, have been
many. Their individual enumeration is beyond the scope of the present
discussion, and would in any event involve a wearisome exposition of
their distinguishing technical features. Several of these systems are
at present in practical and very effective operation.

One of the forerunners of the printing telegraph systems now in use
was the Buckingham system, for many years employed by the Western
Union Telegraph Company, but now for some time obsolete. The receiving
mechanism of this system printed the messages on telegraph blanks
placed upon a cylinder of just the right circumference to accommodate
two telegraph blanks. The blanks were arranged in pairs, rolled into
the form of a tube and placed around the cylinder. When two messages
had been written a new pair of blanks had to be substituted. This was
a rather awkward arrangement, but at a time when more highly developed
apparatus had not been perfected it served its purpose to good

The printing telegraphs of to-day produce their messages by the
direct operation of typewriting machines or mechanisms operating
substantially in the same manner as the ordinary typewriting machine.
The methods by which the electrical impulses coming over the line are
transformed into mechanical operation of the typewriter keys, or what
corresponds to the typewriter keys, vary. It would be difficult to
describe how this function is performed without entering upon much
detail of a highly technical character. Suffice it to say that means
have been devised by which each combination of electrical impulses
coming over the line wire causes a channel to be opened for the motor
operation of the typewriting key-bar operating the corresponding
letter upon the typewriter apparatus. These machines write the
messages with proper arrangement of the date line, address, text, and
signature, operating not only the type, but also the carriage shift
and the line spacing as required. A further step in advance has
been made by feeding the blanks into the receiving typewriter from
a continuous roll, an attendant tearing the messages off as they are
completed. The entire operation is automatic from beginning to end and
capable of considerable speed.

There remained the problem of devising some means by which a number of
automatic units could be operated over the same line at the same
time. This is not by any means a new proposition. Here again various
solutions have been offered by the scientists both of Europe and of
this country, and different systems designed to accomplish the desired
object have been placed in operation. One of the most recent, and
we believe the most efficient so far developed, is the so-called
multiplex printer system, devised by the engineers of the Western
Union Telegraph Company and now being extensively used by that
company. Perhaps the best picture of what is accomplished by this
system can be given by an illustration. Let us assume a single wire
between New York and Chicago. At the New York end there are connected
with this wire four combined perforators and transmitters, and four
receiving machines operating on the typewriter principle. At the
Chicago end the wire is connected with a like number of sending and
receiving machines. All these machines are in simultaneous operation;
that is to say, four messages are being sent from New York to Chicago,
and four messages are being sent from Chicago to New York, all at the
same time and over a single wire, and the entire process is automatic.
The method by which eight messages can be sent over a single wire at
the same time without interfering with one another cannot readily
be described in simple terms. It may give some comprehension of the
underlying principle to say that the heart of the mechanism is in
two disks at each end of the line, which are divided into groups of
segments insulated from each other, each group being connected to one
of the sending or receiving machines, respectively. A rotating contact
brush connected to the line wire passes over the disk, so that, as it
comes into contact with each segment, the line wire is connected in
turn with the channel leading to the corresponding operating unit. The
brushes revolve in absolute unison of time and position. To use the
same illustration as before, the brush on the Chicago disk and the
brush on the New York disk not only move at exactly the same speed,
but at any given moment the two brushes are in exactly the same
position with regard to the respective group of segments of both
disks. If we now conceive of these brushes passing over the successive
segments of the disks at a very great rate of speed, it may be
understood that the effect is that the electrical impulses are
distributed, each receiving machine receiving only those produced by
the corresponding sending machine at the other end. In other words,
each of the sets of receiving and sending apparatus really gets the
use of the line for a fraction of the time during each revolution
of the brushes of the distributer or disk mechanism. The multiplex
automatic circuits are being extended all over the country and are
proving extremely valuable in handling the constantly growing volume
of telegraph traffic.

What has thus been achieved in developing the technical side of
telegraph operation must be attributed in part to that impulse toward
improvement which is constantly at work everywhere and is the most
potent factor in the progress of all industries, but in large
measure it is the reflex of the growing--and recently very rapidly
growing--demands which are made upon the telegraph service. Emphasis
is placed on the larger ratio of growth in this demand in recent years
because it is peculiarly symptomatic of a noticeably wider realization
of the advantages which the telegraph offers as an effective medium
for business and social correspondence than has heretofore been in
evidence. It means that we have graduated from that state of mind
which saw in the telegraph something to be resorted to only under
the stress of emergency, which caused many good people to associate
a telegram with trouble and bad news and sudden calamity. There are
still some dear old ladies who, on receipt of a telegram, make a rapid
mental survey of the entire roster of their near and distant relatives
and wonder whose death or illness the message may announce before they
open the fateful envelope, only to find that up-to-date Cousin Mary,
who has learned that the telegraph is as readily used as the mail and
many times more rapid and efficient, wants to know whether they can
come out for the week-end. When Cousin Mary of to-day wants to know,
she wants to know right away--not only that she has her arrangements
to make, but also because she just does not propose to wait a day or
two to get a simple answer to a simple question.

Therein she embodies the spirit of the times. Our ancestors were
content to jog along for days in a stuffy stage-coach; we complain
that the train which accomplishes the same distance in a few hours is
too slow. We act more quickly; we think more quickly. We have to if we
want to keep within earshot of the band.

This speeding up makes itself quite obviously most apparent in our
business processes. No body of business men need be told how much
keener competition is becoming daily, how much narrower the margin by
which success must be won. Familiar phrases, these. But behind them
lies a wealth of tragedy. How many have fallen by the way? It is
estimated that something less than ten per cent. of those who engage
in business on their own account succeed. How terrible the percentage
of those who fail! The race has become too swift for them. Driven
by the lash of competition, business must perforce move faster and
faster. Time is becoming ever more precious. Negotiations must be
rapidly conducted, decisions arrived at quickly, transactions closed
on the moment. What wonder that all this makes for a vastly increased
use of the quickest method of communication?

That is but one of the conditions which accounts for the growing use
of the telegraph. Another is to be found in the recognition of the
convenience of the night letter and day letter. This has brought
about a considerable increase in the volume of family and social
correspondence by telegraph, which will grow to very much greater
proportions as experience demonstrates its value. In business life the
night letter and day letter have likewise established a distinct place
for themselves. Here also the present development of this traffic can
be regarded as only rudimentary in comparison with the possibilities
of its future development, indications of which are already apparent.
It has been discovered that the telegram, on account of its peculiar
attention-compelling quality, is an effective medium not only for
the individual appeal, but for placing business propositions before
a number of people at once, the night letters and day letters being
particularly adapted to this purpose by reason of the greater scope of
expression which they offer.

Again, business men are developing the habit of using the telegram
in keeping in touch with their field forces and their salesmen and
encouraging their activities, in cultivating closer contact with their
customers, in placing their orders, in replenishing their stocks,
and in any number of other ways calculated to further the profitable
conduct of their enterprises.

All this means that the telegraph is increasingly being utilized as a
means of correspondence of every conceivable sort. It means also that
with the growing appreciation of its adaptability to the every-day
needs of social and business communication a very much larger public
demand upon it must be anticipated, and it is to meet this demand with
prompt and satisfactory service that the telegraph company has
been bending its efforts to the perfection of a highly developed
organization and of operating appliances of the most modern and
efficient type.


Through the courtesy of J.J. Carty, Esq., Chief Engineer of the
American Telephone and Telegraph Company, there follows the clean-cut
survey of the evolution of the telephone presented in his address
before the Franklin Institute in Philadelphia, May 17, 1916, when he
received the gold medal of the Institute.

More than any other, the telephone art is a product of American
institutions and reflects the genius of our people. The story of its
wonderful development is a story of our own country. It is a story
exclusively of American enterprise and American progress, for,
although the most powerful governments of Europe have devoted their
energies to the development and operation of telephone systems, great
contributions to the art have not been made by any of them. With very
few exceptions, the best that is used in telephony everywhere in the
world to-day has been contributed by workers here in America.

It is of peculiar interest to recall the fact that the first words
ever transmitted by the electric telephone were spoken in a building
at Boston, not far from where Benjamin Franklin first saw the light.
The telephone, as well as Franklin, was born at Boston, and, like
Franklin, its first journey into the world brought it to Philadelphia,
where it was exhibited by its inventor, Alexander Graham Bell, at
the Centennial Exhibition in 1876, held here to commemorate the first
hundred years of our existence as a free and independent nation.

It was a fitting contribution to American progress, representing the
highest product of American inventive genius, and a worthy continuance
of the labors of Franklin, one of the founders of the science of
electricity as well as of the Republic.

Nothing could appeal more to the genius of Franklin than the
telephone, for not only have his countrymen built upon it an
electrical system of communication of transcendent magnitude and
usefulness, but they have made it into a powerful agency for the
advancement of civilization, eliminating barriers to speech, binding
together our people into one nation, and now reaching out to the
uttermost limits of the earth, with the grand aim of some day bringing
together the people of all the nations of the earth into one common

On the tenth day of March, 1876, the telephone art was born, when,
over a wire extending between two rooms on the top floor of a building
in Boston, Alexander Graham Bell spoke to his associate, Thomas A.
Watson, saying: "Mr. Watson, please come here. I want you." These
words, then heard by Mr. Watson in the instrument at his ear,
constitute the first sentence ever received by the electric telephone.
The instrument into which Doctor Bell spoke was a crude apparatus, and
the current which it generated was so feeble that, although the line
was about a hundred feet in length, the voice heard in the receiver
was so faint as to be audible only to such a trained and sensitive ear
as that of the young Mr. Watson, and then only when all surrounding
noises were excluded.

Following the instructions given by Doctor Bell, Mr. Watson with his
own hands had constructed the first telephone instruments and ran the
first telephone wire. At that time all the knowledge of the telephone
art was possessed exclusively by those two men. There was no
experience to guide and no tradition to follow. The founders of the
telephone, with remarkable foresight, recognized that success depended
upon the highest scientific knowledge and technical skill, and at once
organized an experimental and research department. They also sought
the aid of university professors eminent for their scientific
attainments, although at that time there was no university giving the
degree of Electrical Engineer or teaching electrical engineering.

From this small beginning there has been developed the present
engineering, experimental and research department which is under my
charge. From only two men in 1876 this staff has, in 1915, grown
to more than six hundred engineers and scientists, including former
professors, post-graduate students, and scientific investigators,
graduates of nearly a hundred American colleges and universities, thus
emphasizing in a special way the American character of the art. The
above number includes only those devoted to experimental and research
work and engineering development and standardization, and does
not include the very much larger body of engineers engaged in
manufacturing and in practical field work throughout the United
States. Not even the largest and most powerful government telephone
and telegraph administration of Europe has a staff to be compared with
this. It is in our great universities that anything like it is to
be found, but even here we find that it exceeds in number the entire
teaching staff of even our largest technical institutions.

A good idea may spring up in the mind of man anywhere, but as applied
to such a complex entity as a telephone system, the countless parts of
which cover a continent, no individual unaided can bring the idea to
a successful conclusion. A comprehensive and effective engineering and
scientific and development organization such as this is necessary, and
years of expensive work are required before the idea can be rendered
useful to the public.

But, vital as they are to its success, the, telephone art requires
more than engineers and scientists. So we find that in the building
and operation and maintenance of that vast continental telephone
system which bears the name of Bell, in honor of the great inventor,
there are at work each day more than 170,000 employees, of which
nearly 20,000 are engaged in the manufacture of telephones,
switchboards, cables, and all of the thousands and tens of thousands
of parts required for the operation of the telephone system of

The remaining 150,000 are distributed throughout all of the States
of the Union. About 80,000 of these are women, largely telephone
operators; 50,000 are linemen, installers, cable splicers, and the
like, engaged in the building and maintaining of the continental
plant. There are thousands of other employees in the accounting,
legal, commercial and other departments. There are 2,100 engineers
located in different parts of the country. The majority of these
engineers have received technical training in American technical
schools, colleges, and universities. This number does not include
by any means all of those in the other departments who have received
technical or college training.

In view of the technical and scientific nature of the telephone art,
an unusually high-grade personnel is required in all departments, and
the amount of unskilled labor employed is relatively very small.
No other art calls forth in a higher degree those qualities of
initiative, judgment, skill, enterprise, and high character which have
in all times distinguished the great achievements of America.

In 1876 the telephone plant of the whole world could be carried away
in the arms of one man. It consisted of two crude telephones like the
one now before you, connected together by a wire of about one hundred
feet in length. A piece cut from this wire by Mr. Watson himself is
here in this little glass case.

At this time there was no practical telephone transmitter, no
hard-drawn copper wire, no transposed and balanced metallic circuits,
no multiple telephone switchboard, or telephone switchboard of any
kind, no telephone cable that would work satisfactorily; in fact,
there were none of the multitude of parts which now constitute the
telephone system.

The first practical telephone line was a copy of the best telegraph
line of the day. A line wire was strung on the poles and housetops,
using the ground for the return circuit. Electrical disturbances,
coming from no one knows where, were picked up by this line.
Frequently the disturbances were so loud in the telephone as to
destroy conversation. When a second telephone line was strung
alongside the first, even though perfectly insulated, another surprise
awaited the telephone pioneers. Conversation carried on over one of
these wires could plainly be heard on the other. Another strange
thing was discovered. Iron wire was not so good a conductor for the
telephone current as it was for the telegraph current. The talking
distance, therefore, was limited by the imperfect carrying power of
the conductor and by the confusing effect of all sorts of disturbing
currents from the atmosphere and from neighboring telephone and
telegraph wires.

These and a multitude of other difficulties, constituting problems of
the most intricate nature, impeded the progress of the telephone
art, but American engineers, by persistent study, incessant
experimentation, and the expenditure of immense sums of money, have
overcome these difficulties. They have created a new art, inventing,
developing, and perfecting, making improvements great and small in
telephone, transmitter, line, cable, switchboard, and every other
piece of apparatus and plant required for the transmission of speech.

As the result of nearly forty years of this unceasing, organized
effort, on the 25th of January, 1915, there was dedicated to the
service of the American public a transcontinental telephone line,
3,600 miles long, joining the Atlantic and the Pacific, and carrying
the human voice instantly and distinctly between San Francisco and New
York and Philadelphia and Boston. On that day over this line Doctor
Bell again talked to Mr. Watson, who was now 3,400 miles away. It was
a day of romantic triumph for these two men and for their associates
and their thousands of successors who have built up the great American
telephone art.

The 11th of February following was another day of triumph for the
telephone art as a product of American institutions, for, in the
presence of dignitaries of the city and State here at Philadelphia and
at San Francisco, the sound of the Liberty Bell, which had not been
heard since it tolled for the death of Chief-Justice Marshall,
was transmitted by telephone over the transcontinental line to San
Francisco, where it was plainly heard by all those there assembled.
Immediately after this the stirring tones of the "Star-spangled
Banner" played on the bugle at San Francisco were sent like lightning
back across the continent to salute the old bell in Philadelphia.

It had often been pointed out that the words of the tenth verse of the
twenty-fifth chapter of Leviticus, added when the bell was recast in
1753, were peculiarly applicable to the part played by the old bell in
1776. But the words were still more prophetic. The old bell had been
silent for nearly eighty years, and it was thought forever, but by the
use of the telephone a gentle tap, which could be heard through the
air only a few feet away, was enough to transmit the tones of the
historic relic all the way across the continent from the Atlantic to
the Pacific. Thus, by the aid of the telephone art, the Liberty Bell
was enabled literally to fulfil its destiny and "Proclaim liberty
throughout all the land, unto all the inhabitants thereof."

The two telephone instruments of 1876 had become many millions by
1916, and the first telephone line, a hundred feet long, had grown to
one of more than three thousand miles in length. This line is but part
of the American telephone system of twenty-one million miles of
wire, connecting more than nine million telephone stations located
everywhere throughout the United States, and giving telephone service
to one hundred million people. Universal telephone service throughout
the length and breadth of our land, that grand objective of Theodore
N. Vail, has been attained.

While Alexander Graham Bell was the first to transmit the tones of
the human voice over a wire by electricity, he was also the first to
transmit the tones of the human voice by the wireless telephone,
for in 1880 he spoke along a beam of light to a point a considerable
distance away. While the method then used is different from that now
in vogue, the medium employed for the transmission is the same--the
ether, that mysterious, invisible, imponderable wave-conductor which
permeates all creation.

While many great advances in the wireless art were made by Marconi and
many other scientists in America and elsewhere, it remained for that
distinguished group of American scientists and engineers working under
my charge to be the first to transmit the tones of the human voice in
the form of intelligible speech across the Atlantic Ocean. This great
event and those immediately preceding it are so fresh in the public
mind that I will make but a brief reference to them here.

On April 4, 1915, we were successful in transmitting speech without
the use of wires from our radio station at Montauk Point on Long
Island to Wilmington, Delaware.

On May 18th we talked by radio telephone from our station on Long
Island to St. Simon Island in the Atlantic Ocean, off the coast of

On the 27th of August, with our apparatus installed by permission of
the Navy Department at the Arlington, Virginia, radio station, speech
was successfully transmitted from that station to the Navy wireless
station equipped with our receiving apparatus at the Isthmus of

On September 29th, speech was successfully transmitted by wire from
New York City to the radio station at Arlington, Virginia, and thence
by wireless telephone across the continent to the radio station at
Mare Island Navy-yard, California, where I heard and understood the
words of Mr. Theodore N. Vail speaking to me from the telephone on his
desk at New York.

On the next morning at about one o'clock, Washington time, we
established wireless telephone communication between Arlington,
Virginia, and Pearl Harbor in the Hawaiian Islands, where an engineer
of our staff, together with United States naval officers, distinctly
heard words spoken into the telephone at Arlington, Virginia. On
October 22d, from the Arlington tower in Virginia, we successfully
transmitted speech across the Atlantic Ocean to the Eiffel Tower at
Paris, where two of our engineers, in company with French military
officers, heard and understood the words spoken at Arlington.

On the same day when speech was being transmitted by the apparatus at
Arlington to our engineers and to the French military officers at the
Eiffel Tower in Paris, our telephone engineer at Pearl Harbor, Hawaii,
together with an officer of the United States Navy, heard the words
spoken from Arlington to Paris and recognized the voice of the

As a result of exhaustive researches, too extensive to describe here,
it has been ascertained that the function of the wireless telephone
is not to do away with the use of wires, but rather to be employed
in situations where wires are not available or practicable, such as
between ship and ship, and ship and shore, and across large bodies of
water. The ether is a universal conductor for wireless telephone
and telegraph impulses and must be used in common by all who wish to
employ those agencies of communication. In the case of the wireless
telegraph the number of messages which may be sent simultaneously is
much restricted. In the case of the wireless telephone, owing to the
thousands of separate wave-lengths required for the transmission of
speech, the number of telephone conversations which may be carried on
at the same time is still further restricted and is so small that
all who can employ wires will find it necessary to do so, leaving the
ether available for those who have no other means of communication.
This quality of the ether which thus restricts its use is really
a characteristic of the greatest value to mankind, for it forms a
universal party line, so to speak, connecting together all creation,
so that anybody anywhere, who connects with it in the proper manner,
may be heard by every one else so connected. Thus, a sinking ship or a
human being anywhere can send forth a cry for help which may be heard
and answered.

No one can tell how far away are the limits of the telephone art, I
am certain that they are not to be found here upon the earth, for
I firmly believe in the fulfilment of that prophetic aspiration
expressed by Theodore N. Vail at a great gathering in Washington, that
some day we will build up a world telephone system, making necessary
to all peoples the use of a common language or a common understanding
of languages which will join all of the people of the earth into one
brotherhood. I believe that the time will come when the historic bell
which now rests in Independence Hall will again be sounded, and
that by means of the telephone art, which to-day has received such
distinguished recognition at your hands, it will proclaim liberty
once more, but this time throughout the whole world unto all the
inhabitants thereof. And, when this world is ready for the message, I
believe the telephone art will provide the means for transmitting to
all mankind a great voice saying, "Peace on earth, good will toward
