Alexander Graham Bell_biography

Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone. 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. In retrospect, Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study.

Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics. In 1888, Alexander Graham Bell became one of the founding members of the National Geographic Society.

He was born in Edinburgh on March 3, 1847. He had two brothers: Melville James Bell and Edward Charles Bell. Both of his brothers died because of tuberculosis. His father was Professor Alexander Melville Bell, and his mother was Eliza Grace. Alexander Graham Bell displayed a natural curiosity about his world, resulting in gathering botanical specimens as well as experimenting even at an early age. His best friend was Ben whose family operated a flour mill gave him idea. Bell built a homemade device that combined rotating paddles with sets of nail brushes, creating a simple dehusking machine that was put into operation and used steadily for a number of years. In return, John Herdman gave both boys the run of a small workshop within which to "invent". Bell showed a sensitive nature and a talent for art, poetry and music that was encouraged by his mother. With no formal training, he mastered the piano and became the family's pianist. Bell's preoccupation with his mother's deafness led him to study acoustics. As a young child, Bell, like his brothers, received his early schooling at home from his father. At an early age, however, he was enrolled at the Royal High School, Edinburgh, Scotland, which he left at age 15, completing only the first four forms.

His first experiment was related with sound. By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage with progress it made both at his new Boston "laboratory" (a rented facility) as well as at his family home in Canada a big success. Bell experimented with a "phonautograph," a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. After through a lot of failure, at last he found a telephone which can be use by people nowadays for communicating from one place to another even though it is far.
