(395231) Leonscott Main-belt Asteroid
Discovered on 25 November 2005 by CSS at Catalina.
Édouard-Léon Scott de Martinville (1817–1879) was a French inventor who in 1857 created the phonautograph, the first device to inscribe airborne sound waves onto paper. Overshadowed by Edison’s phonograph, Scott’s work resurfaced in 2008, when his 1860 “Au clair de la lune” was first played back, revealing the earliest clearly recognizable human voice.Naming citation (WGSBN Bull. 6, #7, 10), IAU / Minor Planet Center, via NASA/JPL
