Answer 1

Alexander Graham Bell (born 3 March 1847-Beinn Bhreagh, Canada, 2 August 1922) was a British scientist, inventor and speech therapist, naturalized American. He contributed to the development of telecommunications and aviation technology. After a series of formalities (later extended for years in the form of judicial claims), he obtained the telephone patent in the United States in 1876, 1 although the apparatus had already been developed previously by the Italian Antonio Meucci. Meucci was officially and posthumously recognized as inventor of the telephone more than one hundred and twenty years later, on June 11, 2002,23 4 although some modern scholars disagree that Bell's work on the telephone outside influenced by Meucci's inventions.5 6 Regardless of whether or not he invented the device, the company that created the patent to exploit the patent, the Bell Telephone Company, was the protagonist of the first steps of the vertiginous implantation of the telephone as a means of mass communication on an international scale. Many other inventions occupied much of Bell's life, including the construction of hydrofoils and aeronautics studies. His father, grandfather and brother were related to phonation and locution work (his mother and his wife were deaf), which profoundly influenced Bell's interest in research on listening and speaking, as well as on his experiments with hearing aids. In 1888, Alexander Graham Bell was one of the founders of the National Geographic Society and 7 of January of 1898, assumed the presidency of that institution.
