South African-born sculptor who moved to England in 1956. In 1957–60 he studied under Anthony Caro at St Martin's School of Art and subsequently worked as assistant to Henry Moore. He took part in the *‘New Generation’ sculpture exhibition at the Whitechapel Gallery in 1965. As with other artists in the exhibition his work was brightly coloured, large, and abstract, but it was more organic in form than that of his contemporaries and he expressed a preference for wood as a material over fibreglass and iron, which he regarded as ‘cold and impersonal’. In 1965 he went to the United States to teach at Bennington College, Vermont, and spent most of his subsequent life there. In the late 1970s he evolved an innovative method of bronze sculpture, pouring the molten metal directly and freely into sand.
