Overview: Correspondence, administrative records, scientific reports, writings, and illustrative material on the expeditions to Peru sponsored by Yale University between 1911 and 1915. The most celebrated discoveries, the finding of Machu Picchu and of Vitcos, the last capital of the Incas, were studied during the expeditions by scientific specialists who were drawn principally from the Yale faculty. The papers include their diaries, manuscripts, and published reports of their work, as well as the writings of Hiram Bingham III, professor of Latin American history at Yale and leader of the expeditions. Among the prominent members of the expeditions were: Isaiah Bowman, Orator F. Cook, George F. Eaton, William G. Erving, H. W. Foote, Herbert E. Gregory, Edmund Heller, and Philip Ainsworth Means. Correspondents included scientists and government officials both in South America and the United States. Among these are: Sir Clements Markham, Alberto A. Giesecke, Edward C. Pickering, Thomas Barbour, Pliny E. Goddard, A. B. Leguia (President of Peru), F. A. Prezet, and Edwardo Higginson.
