George Clapp Vaillant was born in Boston, Massachusetts and educated at Noble and Greenough School and Phillips Academy. Vaillant attended Harvard University where he was a lackluster student until he discovered archaeology. Vaillant worked on the cliff-houses in northeastern Arizona and dug at Pecos, New Mexico while an undergraduate. In graduate school, Vaillant worked with George A. Reisner in Egypt. Under the direction of the Carnegie Foundation and Sylvanus Morley, he dug at Chichen Itza in 1926. Following his time in Mexico with Morley, Vaillant was appointed assistant curator at the American Museum of Natural History in New York, in charge of archaeological activities in Mexico. This employment lasted until 1941 when he was appointed Director of the University of Pennsylvania Museum. The George C. Vaillant Administrative records are contained in five archival boxes and consist mostly of correspondence with some administrative records and personal files.
