Steer, Philip Wilson, 1860-1942, English landscape painter. Steer worked largely in the tradition of French impressionist painting and was considered the greatest English landscape painter of his day. He brought to his subjects a considerable understanding of pattern, color, space, and especially light effects. Examples of his work are Chepstow Castle, Music Room (Tate Gall., London) and a self-portrait (Uffizi). The Tate Gallery owns many of his works.
