(b Kheredine, Tunisia, 1 May 1934).
British sculptor. He is probably the most renowned of the generation of avant-garde British sculptors (mainly, like himself, pupils of Caro) who came to prominence at the New Generation exhibition in 1965. His work at this time was characteristically in smooth, man-made materials such as plastic or fibreglass, often brightly coloured, with the cone shape being a favourite motif (And the Birds Began to Sing, 1964, Tate, London). At the end of the decade he began using more rugged materials, including steel and wood. With Bridget Riley he represented Britain at the Venice Biennale of 1968 and his work has been included in many other international exhibitions. He has taught at various art schools in Britain and elsewhere and from 1980 to 1990 he was professor of sculpture at the Royal College of Art. He was president of the Royal Academy, 1999–2004.
