Bell's 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.[8] His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876.[N 2] Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study.[9][N 3]
Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Bell also had a strong influence on the National Geographic Society[11] and its magazine while serving as the second president from January 7, 1898, until 1903.
Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity.[12] His work in this area has been called "the soundest, and most useful study of human heredity proposed in nineteenth-century America... Bell's most notable contribution to basic science, as distinct from invention."[13]
