Alexander Graham Bell Alexander Graham Bell (/ ˈɡreɪ.əm /; March 3, 1847 – August 2, 1922) was a Scottish-born inventor, scientist, and engineer who is credited with inventing and patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885.

Receiving a U.S. patent for the invention of the telephone on March 7, 1876, Alexander Graham Bell formed the Bell Telephone Company in 1877, which in 1885 became AT&T.
