Did you know that humanity's first recording was done by Édouard-Léon Scott de Martinville in 1860 in Paris? Édouard-Léon Scott de Martinville invented sound recording when he thought of a machine that does for the ear what the camera did for the eye. He called it a phonautograph and it inscribed airborne sounds onto paper, over time, to be studied visually. These recordings he called phonautograms. These phonautograms however could not be played back, they were simply inscriptions of the sound captured.
