Robert Morris was a preeminent American Conceptual artist regarded as one of the early proponents of Minimalism. In one of his best-known series, Morris hung sculpted pieces of dense felt on the wall, the resulting drooping shape, acted as a challenge to painting while offering a new format for sculpture. Born on February 9, 1931 in Kansas City, MO, he studied sculpture at Hunter College in New York and graduated in 1963. One of his works from this era, Steam (1967), consisted of a cloud of steam continuously rising from a large block of rocks, and is regarded as an early example of Land Art. Also an accomplished writer and theorist, he wrote a seminal essay outlining the basis of Minimalism titled Notes on Sculpture, first published in Artforum in 1966.
