Milton Ernest "Robert" Rauschenberg 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 various combinations. Rauschenberg was both a painter and a sculptor, and the combines are a combination of the two, but he also worked with photography, printmaking, papermaking and performance. [Wikipedia]
