Frederick Childe Hassam (October 17, 1859 – August 27, 1935) was a prominent and prolific American Impressionist painter, noted for his urban and coastal scenes. Along with Mary Cassatt and John Henry Twachtman, Hassam was instrumental in promulgating Impressionism to American collectors, dealers, and the museums. He produced over 3,000 paintings, watercolors, etchings, and lithographs in his career, and was a founding member of The Ten, an influential group of American artists of the early 20th century. His most famous works are the Flag paintings, completed during World War I.
