Sound Recorded Before Edison?

In 1878 when Thomas Edison recorded the words "Mary Had a Little Lamb" on a piece of tinfoil, he became considered as the father of recording sound- until now. A few weeks ago another recording was discovered in a Paris archive. The American Audio Historians, the people who discovered the recording, believe it to have been recorded on April 9, 1860, 18 years before Edison prevailed in his attempt to record and play back sound.

Édouard-Léon Scott de Martinville, the little-known Parisian typesetter and tinkerer was the inventor of the phonautograph, and it was he who recorded the first sounds. He recorded 11 seconds of the song 'Au Claire de la Lune' on a machine that was not meant to play the sounds back, but to record them.
