Johann Philipp Reis, the first inventor of an electric telephone, was
born on January 7, 1834, at the little town of Gelnhausen, in Cassel,
where his father was a master baker and petty farmer. The boy lost
his mother during his infancy, and was brought up by his paternal
grandmother, a well-read, intelligent woman, of a religious turn. While
his father taught him to observe the material world, his grandmother
opened his mind to the Unseen.
At the age of six he was sent to the common school of the town, where
his talents attracted the notice of his instructors, who advised his
father to extend his education at a higher college. Mr. Reis died before
his son was ten years old; but his grandmother and guardians afterwards
placed him at Garnier's Institute, in Friedrichsdorf, where he showed a
taste for languages, and acquired both French and English, as well as a
stock of miscellaneous information from the library. At the end of
his fourteenth year he passed to Hassel's Institute, at
Frankfort-on-the-Main, where he picked up Latin and Italian. A love of
science now began to show itself, and his guardians were recommended to
send him to the Polytechnic School of Carlsruhe; but one of them, his
uncle, wished him to become a merchant, and on March 1, 1850, Reis
was apprenticed to the colour trade in the establishment of Mr. J. F
Beyerbach, of Frankfort, against his own will. He told his uncle that he
would learn the business chosen for him, but should continue his proper
studies by-and-by.
By diligent service he won the esteem of Mr. Beyerbach, and devoted his
leisure to self-improvement, taking private lessons in mathematics and
physics, and attending the lectures of Professor R. Bottger on mechanics
at the Trade School. When his apprenticeship ended he attended the
Institute of Dr. Poppe, in Frankfort, and as neither history nor
geography was taught there, several of the students agreed to instruct
each other in these subjects. Reis undertook geography, and believed
he had found his true vocation in the art of teaching. He also became a
member of the Physical Society of Frankfort.
In 1855 he completed his year of military service at Cassel, then
returned to Frankfort to qualify himself as a teacher of mathematics and
science in the schools by means of private study and public lectures.
His intention was to finish his training at the University of
Heidelberg, but in the spring of 1858 he visited his old friend and
master, Hofrath Garnier, who offered him a post in Garnier's Institute.
In the autumn of 1855 he removed to Friedrichsdorf, to begin his new
career, and in September following he took a wife and settled down.
Reis imagined that electricity could be propagated through space, as
light can, without the aid of a material conductor, and he made some
experiments on the subject. The results were described in a paper 'On
the Radiation of Electricity,' which, in 1859, he posted to Professor
Poggendorff; for insertion in the well-known periodical, the ANNALEN
DER PHYSIK. The memoir was declined, to the great disappointment of the
sensitive young teacher.
Reis had studied the organs of hearing, and the idea of an apparatus for
transmitting sound by means of electricity had been floating in his
mind for years. Incited by his lessons on physics, in the year 1860 he
attacked the problem, and was rewarded with success. In 1862 he again
tried Poggendorff, with an account of his 'Telephon,' as he called
it;[The word 'telephone' occurs in Timbs' REPOSITORY OF SCIENCE AND ART
for 1845, in connection With a signal trumpet operated by compressed
air.] but his second offering was rejected like the first. The learned
professor, it seems, regarded the transmission of speech by electricity
as a chimera; but Reis, in the bitterness of wounded feeling, attributed
the failure to his being 'only a poor schoolmaster.'
Since the invention of the telephone, attention has been called to the
fact that, in 1854, M. Charles Bourseul, a French telegraphist, [Happily
still alive (1891).] had conceived a plan for conveying sounds and even
speech by electricity. 'Suppose,' he explained, 'that a man speaks near
a movable disc sufficiently flexible to lose none of the vibrations of
the voice; that this disc alternately makes and breaks the currents
from a battery: you may have at a distance another disc which will
simultaneously execute the same vibrations.... It is certain that, in a
more or less distant future, speech will be transmitted by electricity.
I have made experiments in this direction; they are delicate and demand
time and patience, but the approximations obtained promise a favourable
result.'[See Du Moncel's EXPOSE DES APPLICATIONS, etc.]
Bourseul deserves the credit of being perhaps the first to devise an
electric telephone and try to make it; but to Reis belongs the honour of
first realising the idea. A writer may plot a story, or a painter invent
a theme for a picture; but unless he execute the work, of what benefit
is it to the world? True, a suggestion in mechanics may stimulate
another to apply it in practice, and in that case the suggester is
entitled to some share of the credit, as well as the distinction of
being the first to think of the matter. But it is best when the original
deviser also carries out the work; and if another should independently
hit upon the same idea and bring it into practice, we are bound to
honour him in full, though we may also recognise the merit of his
predecessor.
Bourseul's idea seems to have attracted little notice at the time, and
was soon forgotten. Even the Count du Moncel, who was ever ready to
welcome a promising invention, evidently regarded it as a fantastic
notion. It is very doubtful if Reis had ever heard of it. He was led to
conceive a similar apparatus by a study of the mechanism of the human
ear, which he knew to contain a membrane, or 'drum,' vibrating under the
waves of sound, and communicating its vibrations through the hammer-bone
behind it to the auditory nerve. It therefore occurred to him, that if
he made a diaphragm in imitation of the drum, and caused it by vibrating
to make and break the circuit of an electric current, he would be able
through the magnetic power of the interrupted current to reproduce the
original sounds at a distance.
In 1837-8 Professor Page, of Massachusetts, had discovered that' a
needle or thin bar of iron, placed in the hollow of a coil or bobbin of
insulated wire, would emit an audible 'tick' at each interruption of a
current, flowing in the coil, and that if these separate ticks followed
each other fast enough, by a rapid interruption of the current, they
would run together into a continuous hum, to which he gave the name of
'galvanic music.' The pitch of this note would correspond to the rate of
interruption of the current. From these and other discoveries which had
been made by Noad, Wertheim, Marrian, and others, Reis knew that if
the current which had been interrupted by his vibrating diaphragm were
conveyed to a distance by a metallic circuit, and there passed through
a coil like that of Page, the iron needle would emit a note like that
which had caused the oscillation of the transmitting diaphragm. Acting
on this knowledge, he constructed a rude telephone.
Dr. Messel informs us that his first transmitter consisted of the bung
of a beer barrel hollowed out in imitation of the external ear. The cup
or mouth-piece thus formed was closed by the skin of a German sausage to
serve as a drum or diaphragm. To the back of this he fixed, with a
drop of sealing-wax, a little strip of platinum, representing the
hammer-bone, which made and broke the metallic circuit of the current as
the membrane oscillated under the sounds which impinged against it. The
current thus interrupted was conveyed by wires to the receiver, which
consisted of a knitting-needle loosely surrounded by a coil of wire
fastened to the breast of a violin as a sounding-board. When a musical
note was struck near the bung, the drum vibrated in harmony with the
pitch of the note, the platinum lever interrupted the metallic circuit
of the current, which, after traversing the conducting wire, passed
through the coil of the receiver, and made the needle hum the original
tone. This primitive arrangement, we are told, astonished all who heard
it. [It is now in the museum of the Reichs Post-Amt, Berlin.]
Another of his early transmitters was a rough model of the human ear,
carved in oak, and provided with a drum which actuated a bent and
pivoted lever of platinum, making it open and close a springy contact
of platinum foil in the metallic circuit of the current. He devised some
ten or twelve different forms, each an improvement on its predecessors,
which transmitted music fairly well, and even a word or two of speech
with more or less perfection. But the apparatus failed as a practical
means of talking to a distance.
The discovery of the microphone by Professor Hughes has enabled us to
understand the reason of this failure. The transmitter of Reis was based
on the plan of interrupting the current, and the spring was intended to
close the contact after it had been opened by the shock of a vibration.
So long as the sound was a musical tone it proved efficient, for a
musical tone is a regular succession of vibrations. But the vibrations
of speech are irregular and complicated, and in order to transmit
them the current has to be varied in strength without being altogether
broken. The waves excited in the air by the voice should merely produce
corresponding waves in the current. In short, the current ought to
UNDULATE in sympathy with the oscillations of the air. It appears
from the report of Herr Von Legat, inspector of the Royal Prussian
Telegraphs, on the Reis telephone, published in 1862, that the inventor
was quite aware of this principle, but his instrument was not well
adapted to apply it. No doubt the platinum contacts he employed in the
transmitter behaved to some extent as a crude metal microphone, and
hence a few words, especially familiar or expected ones, could be
transmitted and distinguished at the other end of the line. But Reis
does not seem to have realised the importance of not entirely breaking
the circuit of the current; at all events, his metal spring is not in
practice an effective provision against this, for it allows the metal
contacts to jolt too far apart, and thus interrupt the current. Had he
lived to modify the spring and the form or material of his contacts so
as to keep the current continuous--as he might have done, for example,
by using carbon for platinum--he would have forestalled alike Bell,
Edison, and Hughes in the production of a good speaking telephone. Reis
in fact was trembling on the verge of a great discovery, which was,
however, reserved for others.
His experiments were made in a little workshop behind his home at
Friedrichsdorff; and wires were run from it to an upper chamber. Another
line was erected between the physical cabinet at Garnier's Institute
across the playground to one of the class-rooms, and there was a
tradition in the school that the boys were afraid of creating an uproar
in the room for fear Herr Reis should hear them with his 'telephon.'
The new invention was published to the world in a lecture before the
Physical Society of Frankfort on October 26, 1861, and a description,
written by himself for the JAHRESBERICHT, a month or two later. It
excited a good deal of scientific notice in Germany; models of it were
sent abroad, to London, Dublin, Tiflis, and other places. It became a
subject for popular lectures, and an article for scientific cabinets.
Reis obtained a brief renown, but the reaction soon set in. The Physical
Society of Frankfort turned its back on the apparatus which had given
it lustre. Reis resigned his membership in 1867; but the Free German
Institute of Frankfort, which elected him an honorary member, also
slighted the instrument as a mere 'philosophical toy.' At first it was
a dream, and now it is a plaything. Have we not had enough of that
superior wisdom which is another name for stupidity? The dreams of the
imagination are apt to become realities, and the toy of to-day has a
knack of growing into the mighty engine of to-morrow.
Reis believed in his invention, if no one else did; and had he been
encouraged by his fellows from the beginning, he might have brought it
into a practical shape. But rebuffs had preyed upon his sensitive heart,
and he was already stricken with consumption. It is related that, after
his lecture on the telephone at Geissen, in 1854, Professor Poggendorff,
who was present, invited him to send a description of his instrument
to the ANNALEN. Reis answered him,'Ich danke Ihnen recht Sehr, Herr
Professor; es ist zu spaty. Jetzt will ICH nicht ihn schickeny. Mein
Apparat wird ohne Beschreibung in den ANNALEN bekannt werden.' ('Thank
you very much, Professor, but it is too late. I shall not send it now.
My apparatus will become known without any writing in the ANNALEN.')
Latterly Reis had confined his teaching and study to matters of science;
but his bad health was a serious impediment. For several years it was
only by the exercise of a strong will that he was able to carry on his
duties. His voice began to fail as the disease gained upon his lungs,
and in the summer of 1873 he was obliged to forsake tuition during
several weeks. The autumn vacation strengthened his hopes of recovery,
and he resumed his teaching with his wonted energy. But this was the
last flicker of the expiring flame. It was announced that he would show
his new gravity-machine at a meeting of the Deutscher Naturforscher of
Wiesbaden in September, but he was too ill to appear. In December he lay
down, and, after a long and painful illness, breathed his last at five
o'clock in the afternoon of January 14, 1874.
In his CURRICULUM VITAE he wrote these words: 'As I look back upon my
life I call indeed say with the Holy Scriptures that it has been "labour
and sorrow." But I have also to thank the Lord that He has given me His
blessing in my calling and in my family, and has bestowed more good upon
me than I have known how to ask of Him. The Lord has helped hitherto; He
will help yet further.'
Reis was buried in the cemetery of Friedrichsdorff, and in 1878, after
the introduction of the speaking telephone, the members of the Physical
Society of Frankfort erected over his grave an obelisk of red sandstone
bearing a medallion portrait.
