Nicolas-Philippe Ledru, known as Comus, was a French physicist, prestidigitator and illusionist of the late 18th century. He had two sons, Jacques Philippe Ledru (1754–1832), a member of the French National Academy of Medicine and a mayor of Fontenay-aux-Roses, and Jacques Auguste Ledru, an inspector of pawn-shops. The latter was the father of Alexandre Auguste Ledru-Rollin, a lawyer and a French politician.
