Who invented the Telephone ?

Alexander Graham Bell

  • On March 1876, the telephone was invented by Alexander Graham Bell (1847-1922) who was a Scottish-born American scientist, inventor, engineer, innovator, and teacher of the deaf. As a boy, Alexander Graham Bell was fascinated by the mechanics of speech and sound. As an adult, he followed in his father’s footsteps and taught elocution to the deaf and hard of hearing.
  • Working with his assistant Thomas A. Watson, he discovered the potential for sound waves to travel over a wire. He did this because he wanted to talk to people near and far without writing letters.
  • Mr Watson, come here. I want to see you ! “. These historic words, the first articulate sentence ever spoken over an electric telephone, were uttered by Alexander Graham Bell when he spilled on his clothes some sulphuric acid which was part of the transmission apparatus. It was the night of March 10, 1876. The receiver was a tuned reed.
  • Alexander Graham Bell achieves the invention of telephone, graphophone, and twisted pair.
