Édouard-Léon Scott de Martinville ([e.dwaʁ.le.ɔ̃ skɔt də maʁ.tɛ̃.vil]; 25 April 1817 – 26 April 1879) was a French printer, bookseller and inventor. He invented the earliest known sound recording device, the phonautograph , which was patented in France on 25 March 1857.
Later, researchers discovered that a misinterpretation of a reference frequency had led to the playback speed being doubled. Once corrected, it became apparent that the recording was likely of a man, probably of the inventor Édouard-Léon Scott de Martinville himself, singing the French folk song "Au clair de la lune" at a slow pace.

Earlier recordings, made in 1857, 1854, and 1853, also contain Scott de Martinville's voice but are unintelligible because of their low quality, brevity and irregularity of speed. [26] Only one of these recordings, 1857 cornet scale recording, was restored and made intelligible.
As of 2023, the oldest recording on the list is Edouard-Leon Scott de Martinville's Phonautograms which date back to the 1850s. [113] The most recent is the Chamber Music Northwest's rendition of Ellen Taaffe Zwilich's Concerto for Clarinet and Chamber Ensemble from 2012. [114] Selections vary widely in duration.
