Many inventors have barely escaped with their lives from the fury of mobs who thought the inventor would take their living from them. Papin, and Hargreaves, and Arkwright all learned what such resistance meant. But as one invention has succeeded another people have grown wiser, and realized that each has conferred a benefit rather than taken away a right. Howe was one of the last to find the people he hoped to benefit aligned against him. The world has moved, since Galileo’s day, and the inventor is now known as the great benefactor. But Howe’s life was a fight, and his triumph that of one of the great martyrs of invention.

BELL AND THE TELEPHONE
1847-
None of the inventions that have resulted from the study of electricity have been stumbled upon in the dark. Scientists in both England and America had realized the possibility of the telegraph before Morse built his first working outfit in his rooms on Washington Square. Edison took out a patent covering wireless telegraphy before Marconi gave his name to the new means of communication. Often a man who has been following one trail through this new field has come upon another, glanced down it, and decided to go back and explore it more thoroughly another day. Meantime the trail is run down by a rival. The prize has gone to that persevering one who has made that trail his own, and learned its secret while other men were only glancing at it. Alexander Graham Bell was by no means the first man to realize that the sound of the human voice could be sent over a wire. He did not happen to stumble upon this fact. He worked it out bit by bit, from what other men had already learned concerning electricity, and his object was to make the telephone of real use to the world. It so happened that Elisha Gray and Bell each filed a claim upon the telephone at the Patent Office on the same day, February 14, 1876. But it was Bell who was able to place the first telephone at the public’s service.
He came of a family that had long been interested in the study of speech. His father, his grandfather, his uncle, and two brothers had all taught elocution in one form or another at the Universities of Edinburgh, Dublin, and London. His grandfather had worked out a successful system to correct stammering, his father, widely known as a splendid elocutionist, had invented a sign-language that he called “Visible Speech,” which was of help to those learning foreign tongues, and also a system to enable the deaf to read spoken words by the movements of the lips. Naturally enough the young inventor started with a very considerable knowledge of the laws of sound.
Bell was born in Edinburgh March 1, 1847, and educated there and in London. When he was sixteen family influence was able to get him the post of teacher of elocution in certain schools, and he spent his leisure hours studying the science of sound. Soon after he came of age he met two well-known Englishmen who were experts in his line of study, Sir Charles Wheatstone and Alexander J. Ellis. Ellis had translated Helmholtz’s celebrated book on “The Sensations of Tone,” and was able to show Bell in his own laboratory how the German scientist had succeeded in keeping tuning-forks in vibration by the power of electro-magnets, and had blended the tones of several tuning-forks so as to produce approximately the sound of the human voice. This idea was new to Bell, and led him to wonder whether it would not be possible to construct what might be called a musical telegraph, sending different notes over a wire by electro-magnetism, using a piano keyboard to give the different notes.
Sir Charles Wheatstone, the leading English authority on the telegraph, received young Bell with the greatest interest, and showed him a new talking-machine that had been constructed by Baron de Kempelin. Bell studied this closely, discussed it with Wheatstone, and decided that he would devote himself to the problems of reproducing sounds mechanically.
The course of his life was then suddenly altered. His two brothers died in Edinburgh of consumption, and he was told that he must seek a change of climate. Accordingly his father and mother sailed with him to the town of Brantford in Canada. There he at once became interested in teaching his father’s system of “Visible Speech” to a tribe of Mohawk Indians in the neighborhood.
He had already had very considerable success in teaching deaf-mutes to talk by visible speech, or sign-language, and this success was repeated in Canada. Word of it went to Boston, and as a result the Board of Education of that city wrote to him, offering to pay him five hundred dollars if he would teach his system in a school for deaf-mutes there. He was glad to accept, and in 1871 moved to Boston, which he planned to make his permanent residence.
