Alexander Graham Bell

Alexander Graham Bell Alexander Graham Bell was a Scottish-born American inventor and scientist who is credited with inventing and patenting the first practical telephone in 1876, and who co-founded the American Telephone and Telegraph Company (AT&T). A lifelong teacher of the deaf—his mother and wife were both deaf—Bell also made important contributions to aeronautics, hydrofoil technology, and optical telecommunications. He considered the telephone a "machine which would allow people to converse despite great distances," and its invention transformed human communication.
