Alexander Graham Bell, a well-known Scottish scientist, inventor, engineer, and innovator was bom on March 3, 1847. He was the second born son of Alexander Melville Bell, a teacher of elocution, and Eliza Grace Symonds, a hearing-impaired pianist. Bell’s father, grandfather, and brother had all been associated with work on elocution and both his mother and wife were deaf, profoundly influencing Bell’s life’s work. In spite of being not the best student, Bell had an uncanny talent for problem solving. When he was 12, he invented a farming device for his friend’s father that quickly and efficiently removed the husks from wheat grain. On March 7, 1876, Bell was awarded a patent on the first telephone. He founded the American Telephone and Telegraph Company (AT&T) in 1885. Many other inventions marked Bell’s later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. He also founded The National Geographic Society and was one of the first presidents and editors of the magazine. Bell died peacefully at his home in Cape Breton Island, Nova Scotia, on August 2, 1922.
