(b Newburgh, NY, 31 May 1923). American painter, sculptor, and printmaker. In the mid-1950s he became recognized as one of the leading exponents of the Hard-Edge style that was one of the reactions against Abstract Expressionism. His paintings are characteristically very clear and simple in conception, sometimes consisting of a number of individual panels placed together, identical in size but each painted a different uniform colour (he started using this formula in 1952).
