British painter, mainly of portraits, but also of landscapes, nudes, and still-lifes. He was born at Belford, Northumberland, the son of a doctor, and studied at the *Slade School, 1926–9. After working in documentary films for the GPO, 1934–7, he returned to full-time painting and in 1937 was one of the founders of the *Euston Road School, which helped to establish a tradition of sober figurative painting of which he was one of the main representatives. In 1939 he joined the Royal Artillery and in 1943–5 he was an *Official War Artist, working in the Near East and then Italy. After the war he taught at Camberwell School of Art, 1945–9, then was professor at the Slade School from 1949 to 1975. He exerted an important influence not only through his teaching there but also through his appointment as chairman of the National Advisory Council on Art Education in 1959. The ‘Coldstream Reports’ of 1960 and 1970 helped to change the structure of art school teaching in Britain, introducing the compulsory study of art history for art students and eventually leading to degree status being awarded to recognized art school courses. Not all art students approved: one poster opposing his proposals bore the words ‘You are old Father William’. Sir Kenneth *Clark had been an early supporter (he gave Coldstream financial assistance in the 1930s), but he came to see his attitude to art as one of ‘dismal rectitude’. Indeed, Coldstream's work as an artist was austere and always based on direct observation.
