Alexander Graham Bell (1847-1922) was a Scottish-born inventor, scientist and engineer who is credited with patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885.
On 7 March 1876, Alexander Graham Bell, scientist, inventor and innovator, received the first patent for an “apparatus for transmitting vocal or other sounds telegraphically,” a device he called the telephone. On 10 March 1876, three days after his patent was issued, Bell and his assistant, Thomas Watson, made the first successfully transmitted message.
Many other inventions marked Bell’s later life, including ground-breaking work in optical telecommunications, hydrofoils, and aeronautics. Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity.
