Robert Rauschenberg (October 22, 1925 – May 12, 2008) was an American painter and graphic artist whose early works anticipated the pop art movement. Rauschenberg is well known for his "Combines" of the 1950s, in which non-traditional materials and objects were employed in innovative combinations. Rauschenberg was both a painter and a sculptor and the Combines are a combination of both, but he also worked with photography, printmaking, papermaking, and performance. He was awarded the National Medal of Arts in 1993.
