The American Art collection includes works spanning major North American art historical movements of the late 19th and early to mid-20th century by important innovators such as Thomas Eakins. Paintings by members of the Ashcan School—including John Sloane—and examples by leading impressionists, such as Childe Hassam are also represented. The collection contains the works of modernists such as Oscar Bluemner, Stanton MacDonald-Wright and Rockwell Kent and masters of Regionalism, including Grant Wood. Works on paper by master Mexican artists, including David Alfaro Siqueiros and Rufino Tamayo comprise an important aspect of the American Art collection.
