American, 1915–1991. Robert Motherwell belonged to the eminent artists’ group of Abstract Expressionism. The American artist was recognized for his use of bold, black shapes featuring against fields of color. He was also an established writer, theorist and advocate of the New York School. His interests, other than art, extended to poetry and philosophy. His psychoanalytical works bridged the pre and post-war avant-garde in Europe, which could be a result of Motherwell’s friendships with European Surrealists and intellectuals.
