The invention of the telephone

Alexander Graham Bell

A physicist, born in Edinburgh, Scotland, 3 March 1847. He is a son of Alexander Melville Bell, mentioned below, and was educated at the Edinburgh high school and Edinburgh University, receiving special training in his father's system for removing impediments in speech. He removed to London in 1867, and entered the University there, but left on account of his health, and went to Canada with his father in 1870. In 1872 he took up his residence in the United States, introducing with success his father's system of deaf-mute instruction, and became professor of vocal physiology in Boston University. He had been interested for many years in the transmission of sound by electricity, and had devised many forms of apparatus for the purpose, but the first public exhibition of his invention was at Philadelphia in 1876. Its complete success has made him wealthy. His invention of the "photophone," in which a vibratory beam of light is substituted for a wire in conveying speech, has also attracted much attention, but has never been practically used. It was first described by him before the American association for the advancement of science in Boston, 27 August 1880.
