Bell's grandfather was a professor of elocution in London and his father an authority on the physiology of the voice and on elocution; Bell was to follow in their footsteps. He was educated in Edinburgh, leaving school at 13. In 1863 he went to Elgin, Morayshire, as a pupil teacher in elocution, with a year's break to study at Edinburgh University; it was in 1865, while still in Elgin, that he first conceived the idea of the electrical transmission of speech. He went as a master to Somersetshire College, Bath (now in Avon), and in 1867 he moved to London to assist his father, who had taken up the grandfather's work in elocution. In the same year, he matriculated at London University, studying anatomy and physiology, and also began teaching the deaf. He continued to pursue the studies that were to lead to the invention of the telephone. At this time he read Helmholtz's The Sensations of Tone, an important work on the theory of sound that was to exert a considerable influence on him.
In 1870 he accompanied his parents when they emigrated to Canada. His work for the deaf gained fame in both Canada and the USA, and in 1873 he was apponted professor of vocal physiology and the mechanics of speech at Boston University, Massachusetts. There, he continued to work on his theory that sound wave vibrations could be converted into a fluctuating electric current, be sent along a wire and then be converted back into sound waves by means of a receiver. He approached the problem from the background of the theory of sound and voice production rather than from that of electrical science, and by 1875 he had succeeded in constructing a rough model. On 7 March 1876 Bell spoke the famous command to his assistant, "Mr Watson, come here, I want you": this was the first time a human voice had been transmitted along a wire. Only three days earlier, Bell's first patent for the telephone had been granted. Almost simultaneously, but quite independently, Elisha Gray had achieved a similar result. After a period of litigation, the US Supreme Court awarded Bell priority, although Gray's device was technically superior.
In 1877, three years after becoming a naturalized US citizen, Bell married the deaf daughter of his first backer. In August of that year, they travelled to Europe to combine a honeymoon with promotion of the telephone. Bell's patent was possibly the most valuable ever issued, for it gave birth to what later became the world's largest private service organization, the Bell Telephone Company.
Bell had other scientific and technological interests: he made improvements in telegraphy and in Edison's gramophone, and he also developed a keen interest in aeronautics, working on Curtiss's flying machine. Bell founded the celebrated periodical Science.
