American abstract painter, born in Washington, DC. Studied at Wilson Teachers College and 1953-5 at the Catholic University under Kenneth Noland, who became a close friend. Shared a studio with Tom Downing 1956-8. Supported himself for some years mainly by teaching at high schools and elsewhere. Began in 1959 to use all-over speckled dots of colour and had his first one-man exhibition at the Origo Gallery, Washington; then worked from 1961 to 1966 with symmetrical geometric images made up of back-to-back E's or L's etc., using the same basic compositions for series of colour variations. Included in Clement Greenberg's exhibition Post Painterly Abstraction at the Los Angeles County Museum 1964, The Washington Color Painters at the Washington Gallery of Modern Art 1965 and Systemic Painting at the Guggenheim Museum, New York, 1966. From 1967 his work has tended to be less symmetrical, with a more dynamic, rhythmical structure. Lives in Washington.
