Alexander Graham Bell

Alexander Graham Bell

(March 3, 1847 – August 2, 1922) was a Scottish-born[N 2] scientist,
inventor, engineer, and innovator who is credited with patenting the first practical telephone[7] and founding the American Telephone and Telegraph Company (AT&T) in 1885.

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. 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 in 1876.[N 3] Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. [N 4]

Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Although Bell was not one of the 33 founders of the National Geographic Society, he had a strong influence on the magazine while serving as the second president from January 7, 1898, until 1903. 

Early life

Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at 16 South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (1845–70) and Edward Charles Bell (1848–67), both of whom would die of tuberculosis. His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace (née Symonds). Born as just "Alexander Bell", at age 10, he made a plea to his father to have a middle name like his two brothers. [N 5] For his 11th birthday, his father acquiesced and allowed him to adopt the name "Graham", chosen out of respect for Alexander Graham, a Canadianbeing treated by his father who had become a family friend. To close relatives and friends he remained "Aleck".

Death

Bell died of complications arising from diabetes on August 2, 1922, at his private estate in Cape Breton, Nova Scotia, at age 75. Bell had also been afflicted with pernicious anemia. His last view of the land he had inhabited was by moonlight on his mountain estate at 2:00 a.m. While tending to him after his long illness, Mabel, his wife, whispered, "Don't leave me." By way of reply, Bell signed "no...", lost consciousness, and died shortly after.
