  • On March 7, 1876, Bell was awarded the first U.S. patent for the telephone.
  • Bell's first telephone was a very simple device. It consisted of a mouthpiece and a receiver, which were connected by electrical wires.
  • When a person spoke into the mouthpiece, the sound waves were converted into electrical signals.
  • The electrical signals were then transmitted over the wires to the receiver, where they were converted back into sound waves.

Later life

  • Bell continued to invent throughout his life.
  • He is credited with inventing the metal detector, the audiometer, and the hydrofoil.
  • Bell was also a pioneer in the field of aviation.
  • He founded the Aerial Experiment Association in 1907.
  • The association was responsible for developing the tetrahedral kite, which is considered to be the forerunner of the airplane.

Death
