In 1831, Englishman Michael Faraday (1791-1867) proved that vibrations of metal could be converted to electrical impulses. This was the technological basis of the telephone, but no one actually used this system to transmit sound until 1861. In that year, Johann Philip Reis (1834-1874) in Germany is said to have built a simple apparatus that changed sound to electricity and back again to sound. A crude device, it was incapable of transmitting most frequencies, and it was never fully developed. A practical telephone was actually invented independently by two men working in the United States, Elisha Gray and Scottish-born Alexander Graham Bell. Incredibly, both men filed for a patent on their designs at the New York patent office on February 14, 1876, with Bell beating Gray by only two hours! Although Gray had built the first steel diaphragm / electromagnet receiver in 1874, he wasn't able to master the design of a workable transmitter until after Bell had. Bell had worked tirelessly, experimenting with various types of mechanisms, while Gray had become discouraged. According to the famous story, the first fully intelligible telephone call occurred on March 6, 1876, when Bell, in one room, called to his assistant in another room. "Come here, Watson, I want you."

Alexander Gramham Bell Is A Scientist,Inventor,Engineer,And Innovator Who Is Credited With Inventing The First Practical Telephone :) Hopee Yall Us !
That is the correct spelling of the word "innovator" (inventor, trendsetter).
an innovator is a person who invents. The opposite is to not invent
Jamie Cullum is more like THE innovator of Jazz.
