There have always been interesting American artists, and at least two 19th-century painters, Thomas Eakins and Winslow Homer, influenced the course of future art in the United States. During the 1920s and '30s, Edward Hopper and Georgia O'Keeffe emerged as the inspirational new painters of distinctive American traditions. Hopper's work was strongly realist, his still, precise images of desolation and isolated individuals reflecting the social mood of the times. O'Keeffe's art was more abstract, often based on enlarged plants and flowers, and infused with a kind of Surrealism she referred to as ``magical realism''. She may not have been a great painter, but her art was highly influential.
