|Audio historians have found a sound recording that pre-dates Edison's phonograph. The device, the 'phonautograph,' was invented by Édouard-Léon Scott de Martinville abd patented in 1857, some 20 years before Edison unveiled the phonograph. The device recorded images from sounds, tracing squiggles in black soot coating a surface. Recently, First Sounds, a group of audio historians, was able to play back one of Scott's recordings by scanning the phonautogram image and using computer software to translate the squiggles back into sound waves -- a feat that was not technologically possible when the sounds were first recorded.

In this segment, we'll talk about the 'phonautograph' and take a listen to the recording, a 10 second recording of someone singing the French folksong "Au Clair de la Lune," recorded April 9, 1860. Why are some inventors and inventions almost lost to history?
