The American inventor announces his invention of the phonograph, a way to record and play back sound.
Edison stumbled on one of his great inventions--the phonograph--while working on a way to record telephone communication at his laboratory in Menlo Park, New Jersey. His work led him to experiment with a stylus on a tinfoil cylinder, which, to his surprise, played back the short song he had recorded, "MARY HAD A LITTLE LAMB". Public demonstrations of the phonograph made the Yankee inventor world famous, and he was dubbed the "Wizard of Menlo Park."
