Robert Motherwell (January 24, 1915 – July 16, 1991) American painter, printmaker and editor. He was one of the youngest of the New York School , which also included Jackson Pollock, Mark Rothko, Willem de Kooning, and Philip Guston. Robert Motherwell was one of the major artists of the Abstract Expressionist movement and also the leading spokesman for that generation of artists. His paintings, collages, drawings, and prints are in the collections of major museums throughout the world and he remains the subject of intense art-historical study. His work is characterized by a broad range of imagery, within which there are certain recurrent themes and motifs, such as the monumental Elegies to the Spanish Republic, the intensely brooding Iberia paintings, and the lyrical Opens.
