Robert Rauschenberg (born Milton Ernst Rauschenberg; October 22, 1925 – May 12, 2008) was an American artist who came to prominence in the 1950s transition from Abstract Expressionism to Pop Art. He is perhaps most famous for his "Combines" of the 1950s, in which non-traditional materials and objects were employed in innovative combinations. In 1966, with Billy Klüver, Rauschenberg launched Experiments in Art and Technology (E.A.T.) a non-profit organization established to promote collaborations between artists and engineers.
