Traces of sound
The world's first sound recording was not Edison's record of "Mary had a little lamb" in 1877, but an engraving of a French folk song in soot-covered paper made by a Parisian inventor in 1860. It wasn't made to be played back, but with clever technology, sound archivists have recovered the long lost sounds. Read the full story here on the BBC.
