ALEXANDER GRAHAM BELL (1847-1922)
After studying at the University of Edinburgh and University College, London, Bell became his father's assistant. He taught the deaf to talk by adopting his father's system of visible speech (illustrations of speaking positions of the lips and tongue). From 1873 to 1876 Bell experimented with a phonautograph, a multiple telegraph, and an electric speaking telegraph (the telephone). Funds came from the fathers of two of his pupils; one of these men, Gardiner Hubbard, had a deaf daughter, Mabel, who later became Bell's wife. The Bell Company built the first long-distance line in 1884, connecting Boston and New York. The American Telephone and Telegraph Company was organized by Bell and others in 1885 to operate other long-distance lines. By 1889, when insulation was perfected, there were 11, 000 miles of underground wires in New York City. The magazine Science (later the official organ of the American Association for the Advancement of Science) was founded in 1880 because of Bell's efforts. He made numerous addresses and published many monographs. As National Geographic Society president from 1896 to 1904, he fostered the success of the society and its publications. In 1898 he became a regent of the Smithsonian Institution. He was also involved in sheep breeding, hydrodynamics, and aviation projects.
