About the author
Alexander Graham Bell
166 books22 followersBritish-born American inventor Alexander Graham Bell received the first patent for the telephone in 1876, improved the phonograph, and also invented the audiometer, an early hearing aid.
The American Telephone and Telegraph Company, nicknamed Ma Bell after Alexander Graham Bell; order to divest its local service operations in 1984 created the regional Baby Bells.
People credit this eminent scientist, engineer, and innovator with the first practical.
Work on elocution and speech associated his grandfather, father, and brother; his deaf mother and deaf wife profoundly influenced work of his life. His research on speech further led him to experiment with devices, which eventually culminated in award of his first patent in United States. In retrospect, Bell considered his most famous intrusion on his real work as a scientist and refused in his study.
His marked later life included groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. In 1888, he and other members founded the National Geographic Society.
Honors and tributes flowed in increasing numbers as his most famous ubiquitous item and his personal fame. Bell received numerous honorary degrees from colleges and universities, to the extent of the almost burdensome requests. During his life, he also received dozens of major awards, medals, and other tributes. These included statuary monuments to his newly created form of communication, notably that erected in his honor in Brantford, Ontario, in 1917.
A large number of his writings, personal correspondence, notebooks, papers, and other documents reside at the manuscript division of the Library of Congress in the United States as the Alexander Graham Bell family papers and at the Alexander Graham Bell institute at Cape Breton University, Nova Scotia, with available major portions for online viewing.
A number of historic sites and other marks, including the first companies of the United States and Canada, commemorate Bell in North America and Europe.
On religious matters, Bell considered an "agnostic", much to the chagrin of his devout wife.
