On November 17, 1877, the publication Scientific American enthuses about Thomas Edison's new invention: the phonograph, a way to record and play back sound.
Calling it a "wonderful invention," the article describes the machine's capability: "...whoever has spoken or whoever may speak into the mouthpiece of the phonograph, and whose words are recorded by it, has the assurance that his speech may be reproduced audibly in his own tones long after he himself has turned to dust. The possibility is simply startling."
"Speech," the publication continued, "has become, as it were, immortal."
Edison stumbled on the phonograph—one of his great inventions—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.”
