(b London, 17 Sept. 1926; d New York, 2 Jan. 1990).
British art critic and curator, active for much of his career in the USA. In the 1950s he worked at the Institute of Contemporary Arts, London (he was deputy director, 1957–9), and he was prominent in the Independent Group, the cradle of British Pop art (Alloway himself coined this term). He was also a strong supporter of American Abstract Expressionism, and in 1961 he emigrated to the USA, settling in New York, where he became a curator at the Guggenheim Museum and art critic for The Nation. His books include American Pop Art (1974) and Topics in American Art since 1945 (1975). He was married to the British-born painter Sylvia Sleigh (1916–2010) (see feminist art), who settled with him in the USA.
