Alexander Graham Bell, the visionary behind the telephone

 

 

 

The life of Alexander Graham Bell as told by Ève Dumais

 

 

 

 

 

 

On March 10, 1876, in Boston, Alexander Graham Bell said to his assistant the famous phrase: “Mr. Watson, come here, I want to see you! It is with these words that the telephone was officially born. The project manager at the Pointe-à-Callière Museum Ève Dumais recounts the context surrounding the birth of this revolutionary invention and explains why Bell obtained the paternity.

 

Born in Scotland in 1847, Alexander Graham Bell came from a family of researchers interested in sound, speech and elocution. In 1870, he left Scotland for Canada with his family after the death of his two brothers from tuberculosis. The following year, Alexander moved to Boston, the United States, where he taught at a school for the deaf and mute.

 

Alexander Graham Bell is interested in the transmission of sound, the functioning of the human ear and the telegraph. With the help of Thomas A. Watson, he succeeds in reconstructing the human voice by vibrating a metal diaphragm. It then transmits it to a receiver using an electrical signal, which becomes an audible message.

 

A disputed patent

Bell filed his US patent on the invention of the telephone on February 14, 1876, two hours before that of another scientist, Elisha Gray. After many trials, justice recognizes the paternity of the telephone and the technical system associated with it.

 

The rapid development of the telephone

The inventor of the telephone already imagines the use of the device in every home and the existence of telephone wires under the ground and in the air. The phone is first sold in the business community, then it becomes a piece of security, to break the isolation. Alexander Melville Bell, the inventor's father, took care of its marketing and had numerous telephone exchanges installed where telephone operators answered the growing number of subscribers.

 

For his part, Alexander Graham Bell continues to invent all kinds of objects and teach the deaf and dumb. He designs the audiometer, a device that measures the intensity of sound, and is interested in flying machines. Although he works in the United States, Bell often stays at his home in Baddeck, Nova Scotia, in order to get closer to nature.
