(b Lyons, 23 Mar. 1809; d Rome, 21 Mar. 1864).
French painter. He was one of the favourite pupils of Ingres and won the Prix de Rome in 1832. In Italy he was influenced by the monumental decorative tradition and after his return to Paris in 1838 he became the leading muralist of his day, painting vast compositions in such churches as St Vincent-de-Paul (1849–53) and St Germain-des-Prés (1856–61). He was a zealous but rather frigid upholder of Ingres's theories. Flandrin was an excellent portraitist and also painted historical and mythological works. He came from a family of artists. His brothers Auguste (1804–43) and Paul (1811–1902) were likewise pupils of Ingres, and concentrated mainly on portraiture and landscape respectively; his son Paul-Hippolyte (1856–1921) painted religious, historical, and genre scenes.
