Alexander Graham Bell Dies at 75

Scottish scientist, engineer, and inventor Alexander Graham Bell died at the age of 75 on August 2, 1922 due to complications from diabetes.

Born on March 3, 1847, Bell exhibited a natural scientific curiosity and a talent for the arts, which his mother nurtured. His mother (and later in life, his wife) were both deaf, impacting his desire to work with elocution and speech down the road.

Bell’s efforts in the fields of hearing and speech led him to receive a patent in 1876 for the first telephone. In addition to this groundbreaking invention, Alexander Graham Bell alone held 18 other patents, and 12 more with partners, mostly dealing with optical telecommunications, hydrofoils, and aeronautics.

Alexander Graham Bell helped found the National Geographic Society and has been credited as one of the most influential inventors of all time.

First Voice Transmission

Alexander Graham Bell used his own invention, the “photophone”, to transmit the first wireless telephone message on June 3, 1880.

Bell held four different patents for a version of the photophone, which was similar to the telephone but different in their methods of projection; the photophone used light as a source, while the telephone used electricity.

The first voice transmission was sent by Alexander Graham Bell at the top of the Franklin School in Washington D.C. which now carries a plaque that reads: “FROM THE TOP FLOOR OF THIS BUILDING/WAS SENT ON JUNE 3, 1880/OVER A BEAM OF LIGHT TO 1325 ‘L’ STREET/THE FIRST WIRELESS TELEPHONE MESSAGE/IN THE HISTORY OF THE WORLD.”
