born Feb. 9, 1931, Kansas City, Mo., U.S.
U.S. artist.
His first one-man exhibition of paintings was held in San Francisco in 1957. In 1960, while living in New York City, he began producing large, monochromatic geometric sculptures, groups of which he exhibited in specific spatial relationships. His work of this period greatly affected the Minimalist movement, which sought to reduce art to its essence by eliminating personal expression and historical allusion. From the late 1960s, however, Morris moved toward a more spontaneous, if anonymous, expressiveness. He experimented in a wide variety of forms, including the "happening"; "dispersal pieces," in which materials were strewn in apparent randomness on the gallery floor; and environmental projects. His work of the 1970s showed a preoccupation with paradoxes of mental and physical imprisonment.
