(b Etrepagny, Eure, 26 Jan. 1861; d Paris, 19 Aug. 1932).
French painter, designer, and writer. Early in his career he moved in circles that included some of the outstanding avant-garde painters of the day, including Bernard, van Gogh, and Toulouse-Lautrec (all four had been pupils of Cormon). With Bernard, he was one of the pioneers of Cloisonnism, but after about 1890 his work was much more traditional, and he became interested in research into the techniques of the Old Masters, notably Rubens, on whom he wrote a book (1924). He was a prolific draughtsman and made tapestry cartoons for the Beauvais and Gobelins factories.
