"Sound Pioneers: The Forgotten Journey from Phonautograph to Phonograph

The video explores the history of sound recording, starting with Edouard-Leon Scott de Martinville's invention of the Phonautograph in 1857, which could record but not play back sound. Despite its obscurity, Ed's work laid the groundwork for future innovations. Thomas Edison later invented the phonograph in 1877, which allowed sound playback, earning him fame. In 2008, scientists used advanced technology to play back Ed's recordings, revealing them as the earliest known human voice recordings, predating Edison's work by 17 years.
