AN INVENTION FOR SOUND REPRODUCTION

See the source image
Thomas Edison announced his invention of the phonograph
in 1877.       

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.”
