The recent discovery of a phonautogram by Édouard-Léon Scott de Martinville may be the earliest recording of sound in the world, predating that of Thomas Edison by almost 20 years.
Scott is in many ways an unlikely hero of recorded sound. Born in Paris in 1817, he was a man of letters, not a scientist, who worked in the printing trade and as a librarian. He published a book on the history of shorthand, and evidently viewed sound recording as an extension of stenography. In a self-published memoir in 1878, he railed against Edison for "appropriating" his methods and misconstruing the purpose of recording technology. The goal, Scott argued, was not sound reproduction, but "writing speech, which is what the word phonograph means."
