The oldest sound recording went unheard for 148 years.

Édouard-Léon Scott de Martinville patented the phonautograph in 1857. It scratched sound waves as a curve onto soot-blackened paper – there was no way to play it back, because it was meant as a picture. In 2008 researchers scanned his recording of 9 April 1860 optically and turned it back into sound.

Useful: Some data waits centuries for the right method of reading it to be invented.
