Minton was a leading exponent of Neo-Romanticism and an influential figure as a teacher at Camberwell School of Art (1943–7), the Central School of Arts and Crafts (1947–8), and the Royal College of Art (1948–56). He was extremely energetic, travelling widely and producing a large body of work as a painter (of portraits, landscapes, and figure compositions), book illustrator, and designer. After about 1950, however, his work went increasingly out of fashion. He made an effort to keep up with the times with subjects such as the Death of James Dean (1957, Tate, London), but stylistically he changed little. He committed suicide with an overdose of drugs.
