Painter, collagist, printmaker and teacher, born in Sheffield. From 1943-48 he was an apprentice signwriter, which he said taught him more than subsequent teaching. After attending evening classes he won a scholarship to the Royal College of Art, 1948-1952, then with an Abbey Major Scholarship worked in Italy, 1952-53, where he was influenced by the Italian Realists, notably Renato Guttuso. Sheffield and Italy featured in his first one-man show at Beaux Arts Gallery in 1953, and it was in the 1950s that he became a notable member of the Kitchen Sink School. With other Kitchen Sink Painters he exhibited at the Venice Biennale in 1956, in the following year appearing in the Looking at People Show at South London Art Gallery and Pushkin Museum, Moscow. In the same year he was awarded a gold medal for painting at the Moscow Youth Festival and he was also a John Moores Liverpool Exhibition prizewinner. Taught for several years at St Martin’s School of Art, Maidstone College of Art and Royal Academy Schools, being head of printmaking at Norwich School of Art, 1983-91. From the 1960s Greaves’ work lost its Kitchen Sink grittiness, becoming more poetic, linear and allusive. Graves Art Gallery in Sheffield and Leicester Museum and Art Gallery held retrospectives in 1980. Later Solo Shows included Chappel Galleries, Chappel, 2001; Wingfield Arts, Wingfield, 2002; and Paintings & Drawings 1952-2002, at James Hyman Fine Art, and New Prints at the School House Gallery, Wighton, both 2003. His work is held by many public collections in Britain and abroad, including Arts Council, British Museum, Contemporary Art Society, Tate Gallery, Johannesburg Public Gallery in South Africa, Philadelphia Museum of Art in America.
