Robert Zingg and Wendell Bennett were graduate students at the University of Chicago when they led an anthropological expedition to study the Tarahumara in Chihuahua, Mexico for nine months in 1930-1931. The expedition was one of the first modern studies of remote Mexican Indians, and the work published from their studies is one of the few on a culture of Northern Mexico. The collection consists of approximately 400 items ranging from basic clothing and housewares to objects used for dances and ceremonies. It is one of the earliest, most comprehensive, and largest Tarahumara collections in the United States. Some of these items can be seen in the Mexican area on the 3rd floor.
