American abstract painter and sculptor, born in Asheville, North Carolina. Served in the US Air Force 1942-6. Studied at Black Mountain College, North Carolina, under Albers, Bolotowsky and Zadkine 1946-8 and at Zadkine's sculpture studio in Paris 1948-9. First one-man exhibition at the Galerie Creuze, Paris, 1949. Afterwards settled in Washington, DC, where he taught at the Institute of Contemporary Art and the Catholic University. Became very friendly with Morris Louis, and visited New York with him in 1953, when both were greatly impressed by Helen Frankenthaler's technique of staining acrylic paint into unsized canvas. Began in 1958 to paint centralised images of concentric rings of colour, at first with fuzzy, painted-out edges as well as crisply defined contours, then with a precise target-type structure and dynamic interactions of colour. Lived from 1961-3 in New York, then was appointed artist-teacher at Bennington College and moved to South Shaftsbury, Vermont. Painted series of pictures with regular schematic compositions (chevrons 1962-4, diamonds 1964-7, horizontal bands 1967-70, etc.) and different combinations of colour. Has also made a number of sculptures in wood and metal since 1968, and some paintings since 1975 on canvases of irregular shapes. Lives at South Shaftsbury.
