Robert Motherwell (1915 � 1991) was an abstract expressionist painter and printmaker. He was one of the youngest of the New York School (a phrase he coined), which also included Jackson Pollock, Mark Rothko, Willem de Kooning and Philip Guston.

Motherwell was born 1915, in Aberdeen, Washington. In 1932 he studied painting briefly at the California School of Fine Arts in San Francisco. He received a B.A. from Stanford University in 1937 and enrolled for graduate work later that year in the Department of Philosophy at Harvard University, Cambridge, Massachusetts. He travelled to Europe in 1938 for a year of study abroad. His first solo show was presented at the Raymond Duncan Gallery in Paris in 1939.

In September of 1940 he settled in New York, where he entered Columbia University to study art history with Meyer Schapiro, who encouraged him to become a painter. In 1941, Motherwell traveled to Mexico with Roberto Matta for six months. After returning to New York, his circle came to include William Baziotes, Willem de Kooning, Hans Hofmann and Jackson Pollock In 1942, Motherwell was included in the exhibition First Papers of Surrealism at the Whitelaw Reid Mansion, New York. In 1944, Motherwell became editor of the Documents of Modern Art series of books, and he contributed frequently to the literature on Modern art from that time.

He preferred using the starkness of black paint as one of the basic elements of his paintings. He was known to frequently employ the technique of diluting his paint with turpentine to create a shadow effect. His long-running series of paintings "Elegies for the Spanish Republic" is generally considered his most significant project. The origin of imagery for the Spanish Elegies is in Motherwell's 1948 black-and-white illustration for a poem by Harold Rosenberg in the avant-garde periodical, Possibilities. After many experiments in these abstract illuminations, the pattern emerged of black vertical and oval shapes against a white backdrop. These forms were reworked over the years until they were painted in monumental scale in the late 1950s, a time of prolific and brilliant activity in Motherwell's career.

A solo exhibition of Motherwell�s work was held at Peggy Guggenheim�s Art of This Century gallery, New York, in 1944. In 1946, he began to associate with Herbert Ferber, Barnett Newman, and Mark Rothko, and spent his first summer in East Hampton, Long Island. This year, Motherwell was given solo exhibitions at the Arts Club of Chicago and the San Francisco Museum of Art, and he participated in Fourteen Americans at the Museum of Modern Art in New York. The artist subsequently taught and lectured throughout the United States, and continued to exhibit extensively in the United States and abroad. A Motherwell exhibition took place at the Kunsthalle Dusseldorf, the Museum des 20. Jahrhunderts, Vienna, and the Mus�e d�Art Moderne de la Ville de Paris in 1976�77. He was given important solo exhibitions at the Royal Academy, London, and the National Gallery of Art, Washington, D.C., in 1978. A retrospective of his works organized by the Albright-Knox Art Gallery, Buffalo, New York, traveled in the United States from 1983 to 1985. From 1971, the artist lived and worked in Greenwich, Connecticut. He died in 1991 in Cape Cod, Massachusetts.
