 The museum's holdings in Native American art include important collections of Arctic Walrus carvings, art of the Tlingit people, and a growing representation from the Mississippi Valley and the American Southwest.The collection of Pre-Columbian works began in the 19th century through the efforts of the Reverend Sheldon Jackson, an 1855 graduate of the Princeton Theological Seminary.He donated a collection of Native American ethnographic objects to the Seminary, which transferred them to the University's E. M. Museum of Geology and Archaeology, then in 1909 to the Guyot Hall Museum, which, after its closure in 2000, gave them to the Art Museum.
