Samuel Lewis Francis (born 1923) was an American painter and printmaker. He studied botany, medicine and psychology at the University of California, Berkeley.
The artist traveled widely during his career, and he was closely aligned with the Tachisme movement while living abroad in Paris during the 1950s. During the final three decades of his career, his style of large scale bright Abstract expressionism was also closely associated with Color field painting.
He was a founding trustee of Los Angeles’s Museum of Contemporary Art, and his paintings can be found in the collections of the Metropolitan Museum of Art, the Kunstmuseum Basel, and the Centre Georges Pompidou in Paris, among others.
