John Armstrong was born in 1893 in Hastings. He studied at St. John’s College, Oxford, 1912-13, and then at St. John’s Wood School of Art 1913-14. During the war he served in the Royal Field Artillery 1914-19, before briefly returning to St. John’s Wood School. He began his professional career as a theatre designer in London, gaining important patrons including Lillian and Samuel Courtauld, who commissioned Armstrong to decorate a room in their Portman Square home. His first solo exhibition was at the Leicester Galleries in 1928. In 1933 he joined Unit One alongside Ben Nicholson, Paul Nash, Edward Burra, Henry Moore, Edward Wadsworth, John Bigge and Barbara Hepworth, with whom he exhibited at the Unit One exhibition. From the early 1930s onwards his work became Surrealist in style – uncanny, romantically dream-like and heavily imbued with symbolism. Armstrong died in 1973. His work is held in numerous international public collections including the Tate, the Imperial War Museum, and the National Galleries of Scotland.
