Robert Motherwell was an American artist of the Abstractionist and Expressionist era. Though younger than others, he was a contemporary nevertheless of artists like Jackson Pollock and Willem de Kooning. Motherwell’s distinctive style was identified by saturated hues and bold brushstrokes. Later in his career, he transitioned towards making prints. He was perhaps most well-known for his large-scale abstract paintings. Most prominently, he was known for his commission of the East Building in the National Gallery of Art, which opened in 1978.
