The Samuel George Ellsworth photograph collection contains nearly 2,000 photographs that Dr. Ellsworth collected through his research on Utah History. It contains a wide array of scenes ranging from artistic conceptions of prehistoric Utah, to modern day Utah, and from images of the founding of the LDS Church, to Utah's multiple ethnic and religious groups. Also included in the collection are numerous geographical and geological photos, maps of Utah and the United States, and early Native Americans in Utah (including photos taken by Jack Hillers during John Wesley Powell's expedition). A number of the images relate to the economic and technological developments in urban and rural Utah including mining, business, railroads, communications, and education. Finally, there are some of Ellsworth's personal photographs of his extended family in the collection.
