University of Pennsylvania Finding Aids

J. Alden Mason, noted archaeological anthropologist and linguist, was born in Orland, Indiana and attended school in Philadelphia attaining his A.B. from the University of Pennsylvania in 1907. He pursued his Ph.D. at the University of California, Berkeley completing his dissertation on the ethnography of the Salinan Indians of California. Mason was influenced by Alfred J. Kroeber while at Berkeley and Edward Sapir of the University of Pennsylvania. The J. Alden Mason curatorial years (1922-1967) produced three archival boxes of correspondence and in-house memos, along with Section reports, research notes and articles and notes for publication. This material, in addition to personal records of Dr. Mason and evidence of his scholarship were arranged into series and placed in chronological order.

Piedras Negras is a Maya site in Guatemala particularly noted for the beautifully sculpted stelae and hieroglyphic inscriptions it has yielded. Between 1931 and 1939 the University of Pennsylvania Museum conducted extensive excavations at this site. John Allen Mason led the first two seasons of work at the site (1931–1932), and Linton Satterthwaite directed the remaining six seasons (1933–1939, excluding 1938). Most of the monuments at the Museum borrowed from Guatemala were returned in 1947; only Stela 14 and one leg from Altar 4 remain on display in the Museum today. The textual records from the excavations of Piedras Negras consist of 11 linear feet of correspondence, financial records, field notes and diaries, catalogs, and reports and publication materials. The arrangement of the records reflects the original order insofar as could be detected, and portions that had been separated over time were re-integrated into this scheme.
