He studied at Columbia University and the Art Students League. He had his first one-man exhibition in 1957. In 1959 he began writing reviews for Art News and Arts Magazine . In 196062 he made the transition from painting to sculpture and became a leading exponent of Minimalism . Much of his work consists of simple cubes or other geometric units that stand on the floor or are cantilevered from the wall, often in stacks or horizontal progressions. His materials included painted steel, Plexiglas, iron, wood, and concrete. In the 1970s he began to fill the land around his studio in Marfa, Texas, with large-scale sculptures; this area is now a museum.
