Born in London in 1925, Sandra Blow attended St Martin's School of Art (1942-46) and the Royal Academy Schools (1946-47). She lived in Italy and travelled extensively in Spain and France before settling in London in 1950.
An abstract painter who has also used materials such as polyethylene and willow cane to construct pictures, Blow has been said to be concerned pre-eminently with the problems of pure painting: balance and proportion, tension and scale. She has work in numerous collections including the Tate and the Victoria and Albert Museum, London; the Arts Council of Great Britain and the Museum of Modern Art, New York. Between 1961-1975 she taught at the Royal College of Art and was elected an Associate to the Royal Academy in 1971 and a Royal Academician in 1978.
