alexander graham bell (March 3, 1847-August 2, 1922) was a Canadian inventor and entrepreneur. He obtained the patent of the first available telephone in the world
Bell himself is an acoustic physiologist and a teacher of deaf-mute language. Bell's father, grandfather and brother's work are all related to oratory and phonation, and his mother and wife are deaf, all of which have a profound impact on Bell's life work. His research on listening and language further led him to invent experimental listening equipment, which eventually led Bell to be awarded the first American patent for telephone in 1876. Before him, the German Philip Reiss had invented a telephone, but its sound transmission effect was so bad that it could not be used in fact. On March 1th, 1876, Bell and his colleagues tested the first available telephone in the world.
Bell thought his most famous invention was an interruption to his real work as a scientist, so he refused to install a telephone in his studio. In addition, Bell also invented an instrument for measuring hearing, an instrument that can be used to find metals in the human body and other inventions.
Bell has a patent for the invention of the telephone, but it has also been pointed out that Antonio Meiwuqi, who immigrated from Italy to the United States, is the inventor of the telephone. On June 15th, 22, the United States Congress confirmed antonio meucci as the inventor of the telephone. But parliament of canada passed a resolution on June 21st, 22, reiterating that Bell was the inventor of the telephone.
in addition to the telephone, alexander graham bell also invented a giant kite carrying people, invented a hydrofoil for the Canadian navy to compete with German U-boats in World War II, and improved the phonograph. Many other inventions left marks in Bell's later life, including pioneering work in optical communication, hydrofoil and aviation.
alexander graham bell died in Badeck on August 2nd, 1922.
