Alexander Graham Bell (March 3, 1847 – August 2, 1922) was an eminent Scottish-born 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. 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, Bell became one of the founding members of the National Geographic Society.
The great pioneer and inventor died on August 2, 1922 at his summer home near Beddeck, Nova Scotia, Canada. A fitting tribute was paid to him when all the telephone stations on the Bell Telephone network in U.S.A. and Canada remained silent for one minute on the day of his funeral.
Indian Posts and Telgraphs Department brought out a commemorative stamp in honour of this great man whose epoch-making invention has revolutionised the world of communications.
