Harry Green was born in 1920 in London, England. He was a self-taught artist who began his career as a commercial artist, working for advertising agencies and designing posters for the London Underground. In the 1950s, he turned to painting and became known for his abstract expressionist style. Green's work was heavily influenced by the American Abstract Expressionist movement, and he often used bold colors and gestural brushstrokes in his paintings. He exhibited his work in numerous solo and group shows throughout his career, including at the Royal Academy of Arts in London. Green's work can be found in private collections and museums around the world, including the Tate Gallery in London and the Museum of Modern Art in New York. He continued to paint until his death in 2013 at the age of 93.
