Leon Scott
From Wikipedia, the free encyclopedia
Edouard-Leon Scott de Martinville (1817 – April 26, 1879) was a French printer, librarian, and bookseller who lived in Paris. He invented the earliest known sound recording device, the phonautograph, in 1857. The phonautograph used a horn to collect sound, attached to a diaphragm which vibrated a stiff bristle which inscribed an image on a lamp black coated, hand-cranked cylinder. Scott built several devices with the help of Rudolph Koenig, a local musical instrument maker. Unlike Edison's similar 1877 invention, the phonograph, the phonautograph only created visual images of the sound and did not have the ability to play back its recordings. Scott's device was used for scientific investigations of sound waves.
