American painter William Stanley Haseltine was an important figure in the modernist movement. His work is associated with the Hudson River School, the Düsseldorf school of painting, and Luminism. He died in his early fifties, so it is hard to say where his greatest influence came from. However, it is safe to say that his influence on American art is far from limited to either one of these movements. 

Although he became an expatriate in 1865, Haseltine retained close ties with his native land. During his last thirty years, he exhibited his work at several prominent venues, including the Pennsylvania Academy of Fine Arts, National Academy of Design, and Brooklyn Art Association. His works can be found in the Metropolitan Museum of Art, New York, the Fine Arts Museums of San Francisco, the Corcoran Gallery of the United States, the Boston Museum of Art, and the Mariners' Museum in Newport News, Virginia.
