French painter, the son of a miniature painter who did not approve of his son's desire to follow in his occupation. Despite these wishes, Langlois trained with Jacques-Louis David and absorbed his Neoclassical style. He won the Prix de Rome in 1809 and studied in Rome for most of the 1810's. He also exhibited regularly at the Salon beginning in 1805, where he won second prize in 1817 and first prize in 1819. Langlois visited Brussels in 1824 to paint a picture of David. He was admitted to the Académie des Beaux-Arts shortly before his own death. //
