born May 12, 1936, Malden, Mass., U.S.
U.S. painter.
He moved to New York City after studying history at Princeton University and there began his innovative "black paintings" (195860), incorporating symmetrical series of thin white stripes that replicated the canvas shape when seen against their black backgrounds. As a leading figure of Minimalism , in the mid 1960s he began using polychromy in an influential series marked by intersecting geometric curvilinear shapes and plays of vivid and harmonious colours. In the 1970s he began producing sensuously coloured, mixed-media reliefs featuring more organic shapes. He was given retrospective exhibitions at the Museum of Modern Art in 1970 and 1987.
