Who really invented the record player? Here’s an investigation from Your Sound Matters:
The roots of the beloved modern record player or turntable go right back to the origins of recorded sound. It was a French inventor, Édouard-Léon Scott de Martinville, who first realized the process of recording sound back in 1857. His ‘phonautograph’ system was inspired by anatomical drawings of the human ear. It used a horn to collect sound, which was then passed through an elastic membrane attached to a stylus. This rudimentary device would record sound waves by etching them onto sheets of paper. However, it could only visualize sound waves and could not play them back.
