ALEXANDER GRAHAM BELL, THE YOUTH
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 off?
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 thought.
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 telephone.
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 defender.
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.
