(b Saint-Ouen, 5 Dec. 1911; d Orléans, 1 Aug. 1993). French painter, lithographer, and designer of tapestries and stained glass, a pupil of Bissière. During the 1930s his work was influenced by Cubism and Surrealism, but after staying at a Trappist monastery in 1943 he became deeply committed to religion and turned to expressing spiritual meaning through abstract art. Characteristically his paintings feature rich colours within a loose linear grid, creating an effect reminiscent of stained glass (a medium in which he did some of his best work).
