Born in London, he began in 1933 as a trainee in the family laundry business. In 1937-38 he studied at Westminster School of Art, and 1938-40 at the Slade School of Fine Art in London and Oxford. In the Second World War he was a conscientious objector, first working on land drainage in Oxfordshire, then looking after monkeys being studied by the zoologist Solly Zuckerman.
He settled in Zennor, Cornwall in 1945, and in 1946 was co-founder of the Crypt Group. He taught at Bath Academy of Art, Corsham, 1951-56. He was a member of the London Group of artists, and of the Penwith Society of Arts. He died at Penzance, Cornwall. His auction record is £115,250 for his painting "The Indias", set at Sotheby's on 3 November 2010.
Some of his most remarkable works are constructions which he titled IMOOS (Images Moving Out Onto Space). Using a parabolic mirror, he would hang contrasting pairs of painted shapes, which rotated freely. Their reversed reflections enlarged, appearing to move in opposite directions.
He works are also in the collections of the Arts Council, the National Galleries of Scotland, the National Museum & Gallery of Wales, Kelvingrove Art Gallery & Museum, Glasgow, Southampton City Art Gallery, York City Art Gallery, the Ferens Art Gallery, Hull, the Government Art Collection, the Towner Gallery, Eastbourne, Bristol City Museum and Art Gallery, the Usher Gallery, Rugby Art Gallery and Museum, Birmingham Museum & Art Gallery, Abbot Hall Art Gallery, Kendal, the Whitworth Art Gallery and Leeds City Art Gallery.
