American painter and lithographer of a Minimal tendency, concerned with shape and anonymous, single-colour surfaces. Born in North Tonawanda, New York. Studied at Cleveland Institute of Art 1956-59 and Yale University 1959-63. He was a student of the Hard-Edge painter Al Held. He has taught since 1963 at the School of Visual Arts, New York, and elsewhere. First one-man exhibition at the Thibaut Gallery, New York, 1964. Influenced by Stella's shaped canvases, made some paintings in 1964-65 with geometric, asymmetrical shapes and shallow mouldings or other relief elements; subsequently flat cut-out forms, sometimes with a regular curve forming the lower edge. Began c.1967 to use lines to suggest subtle distortion or bending of the picture plane; also an interaction between 'real' and 'warped' squares and circles etc. Has tended to work since 1969 with serial imagery. 1971 Solo museum exhibition at the Solomon R. Guggenheim Museum, New York. 1972 Participated in "documenta" 5 (1977), "documenta" 6 (1977) and "documenta" 7 (1982) in Kassel, West Germany; 1979 participated in 1979 Biennale Exhibition at the Whitney Museum of American Art, New York; again in 1983 & 1985; 1982 Retrospective of paintings at the Stedelijk Museum, Amsterdam. 1993 Received Skowhegan Medal for Painting.
