Alexander Graham Bell

Early Life

Alexander Bell was born on 3 March 1847 in Edinburgh, Scotland, to Alexander Melville Bell, a teacher of elocution, and Eliza Grace Bell. The name Graham was added when he was eleven. Both his mother and his wife were deaf, and his father and grandfather worked on speech and elocution, which shaped his lifelong interest in sound and hearing. He was educated in Edinburgh, at the Royal High School and the University of Edinburgh, and his family moved to London in 1865. After the deaths of his two brothers from tuberculosis, the family emigrated to Canada in 1870, settling near Brantford, Ontario.

Education

Bell was educated at the Royal High School in Edinburgh and attended the University of Edinburgh, where he studied subjects including anatomy and physiology. He did not take a degree. His real training was in his father's system of visible speech, a method of teaching the deaf to speak by showing the positions of the lips, tongue and throat for each sound.

Career

Bell's career began in teaching the deaf. He taught his father's visible-speech system in Britain, moved with his family to Canada in 1870, and in 1871 went to Boston to teach at the Boston School for Deaf Mutes. In 1873 he became professor of vocal physiology at Boston University. His work on speech led him to experiment with transmitting sound electrically, first through a harmonic telegraph and then through the telephone. After the telephone patent of 1876 and the founding of the Bell Telephone Company in 1877, he continued to invent at the Volta Laboratory in Washington, D.C., working on the phonograph, the photophone, the audiometer and a metal detector used in an attempt to locate the bullet in the assassinated President Garfield. In later life he experimented with tetrahedral kites, hydrofoils and aviation through the Aerial Experiment Association, founded in 1907. He became a United States citizen in 1882 and spent his later years at Beinn Bhreagh, his estate in Nova Scotia, where he died in 1922.

Achievements

Bell's central achievement was the telephone, patented in 1876. His experiments with a multiple telegraph led him to a device that turned the vibrations of speech into electrical undulations and back into sound, and on 10 March 1876 he spoke the first intelligible sentence over a wire to his assistant Thomas Watson. The Bell Telephone Company, founded in 1877, carried the invention into homes and businesses, and by 1886 more than 150,000 people in the United States owned telephones. Bell's other inventions included the photophone of 1880, which transmitted speech on light, and an improved phonograph using wax cylinders. He also helped found the journal Science and the National Geographic Society, which he led as president from 1898 to 1903, and he served as a regent of the Smithsonian Institution.

• Patented the first practical telephone in 1876, turning speech into electrical signals that could travel along a wire
• Spoke the first intelligible sentence by telephone on 10 March 1876: 'Watson, come here, I want you'
• Co-founded the Bell Telephone Company in 1877, the ancestor of the modern telephone industry
• Invented the photophone in 1880, which sent speech on a beam of light, a forerunner of fibre-optic communication
• Improved the phonograph with a wax-coated cylinder in 1886, making sound recording practical
• Helped found the journal Science in 1883 and was a founder of the National Geographic Society in 1888, serving as its president from 1898 to 1903
• Founded the Volta Laboratory in Washington, D.C., in 1880, where he worked on the phonograph, the audiometer and aids for the deaf

Legacy

Bell is remembered as the inventor of the telephone, the device that made instant voice communication over distance part of everyday life. The telephone network built on his patent grew into the modern communications system, and his photophone anticipated communication by light. His work for the deaf, including the founding of the Alexander Graham Bell Association for the Deaf and Hard of Hearing, continued after his death. The unit of sound intensity, the bel, and its tenth, the decibel, were named in his honour. His papers are held by the Library of Congress, and his Nova Scotia home, Beinn Bhreagh, is preserved as the Alexander Graham Bell National Historic Site.

Contributions

Bell's contribution was to make the human voice travel by wire. Others had sent coded signals by telegraph, but Bell's telephone carried speech itself, turning sound into electrical undulations and back again. That single change made it possible for people to talk to each other across towns, countries and eventually continents in real time. His photophone, which carried speech on a beam of light, pointed towards a second revolution, optical communication, that arrived a century later. Alongside the inventions, his teaching of the deaf and his support for the journal Science and the National Geographic Society spread scientific knowledge to a wide public.
