168th BIRTHDAY OF ALEXANDER GRAHAM BELL
Alexander Bell was born in Edinburgh, on 3rd March 1847 to Alexander Melville Bell and Eliza Grace Symonds. Bell adopted the name Graham out of admiration for Alexander Graham, a family friend, and later renamed himself as Alexander Graham Bell. He had a strong background of scientific knowledge because his father was a scientist, and his grandfather was a professor. His mother was a proficient pianist despite her deafness. Alexander Graham Bell was a pioneer in the field of telecommunications. He was the inventor of the electrical speech machine which is now called as the telephone. But Bell always described himself simply as a teacher of the deaf, and his contributions in that field were of the first order.

- The Bell Telephone Company was organized on July 9, 1877.
- In 1880, he established the Volta Laboratory, an experimental facility devoted to scientific discovery.
- He developed a metal jacket to assist patients with lung problems
- Conceptualized the process for producing methane gas from waste material
- Developed a photophone
- A metal detector to locate bullets in bodies
- Invented an audiometer to test a person’s hearing.
- In the year 1881, Graham Bell discovered the twisted pair
- In 1886, he invented the first wax recording cylinder.
- He also discovered a device to locate an ice berg. In 1890 he established the American Association to Promote the Teaching of Speech to the Deaf.
- He also invented a graphophone in the year 1890.
- He worked on inventions in flight and devised the tetrahedral kite which had the capacity of carrying one person.
- He is credited for the discovery of the first flight of a heavier-than-air machine in the year 1909.
- In 1917 he founded the world?s fastest boat called the hydrodrome.
PATENTS AND AWARDS
The Bell’s inventive genius is represented only in part by the eighteen patents granted in his name alone and the twelve he shared with his collaborators:
- fourteen for the telephone and telegraph,
- four for the photophone,
- one for the phonograph,
- five for aerial vehicles,
- four for hydroairplanes, and
- two for a selenium cell.
He won many awards for his remarkable inventions. Few notable awards among them were the Elliott Cresson Medal, IEEE Edison Medal, Hughes Medal, and John Fritz Medal. He also received numerous honorary degrees during his life. As a token of tribute, many countries have schools, colleges, institutes, organizations, places, awards and scholarships named after him.
Alexander Graham Bell died peacefully, with his wife by his side, in Cape Breton Island, Nova Scotia, Canada, on August 2, 1922.
