Jean Eugène Robert Houdin or Jean Eugène Robert-Houdin (zhäN özhĕn´ rōbĕr´ ōōdăN´), 1805–71, French conjurer and magician. Originally a clockmaker, he was celebrated for his optical illusions and mechanical devices and for his attributing his "magic" to natural instead of supernatural means. Houdin was the first to use electromagnetism for his effects. He wrote an autobiography (1857) and Secrets of Prestidigitation and Magic (1868). Harry Houdini, who named himself for Houdin, wrote The Unmasking of Robert-Houdin (1908).
