Alexaner Graham Bell (3 March 1847 – 2 August 1922) was an eminent scientist, inventor and innovator who is widely credited with the invention of the telephone. His father, grandfather and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices that eventually culminated in Bell being awarded the first U.S. patent for the invention of the telephone in 1876.
