British sculptor, painter, and printmaker, born in London. He studied at St Martin's School of Art and was one of the young sculptors featured in the 1965 New Generation exhibition. His best-known works are large colourful steel sculptures, which, like those of Anthony Caro, rest on the floor. Swing Low (1964, Tate), which combines an angled box-like structure in yellow with a blue curvilinear shape something between a ribbon and a spring, which both supports and divides it, is typical. Later sculptures were based on the form of the mandala, which he discovered in the psychoanalytic writings of Carl Gustav Jung.
