Henry N. Michael papers, 1938-2004 (inclusive)

Extent:
6.0 cubic feet (4 records storage cartons of papers, 1 records storage carton of index cards and 1 records storage carton of visual materials)
Abstract:
Henry N. Michael was an anthropologist and geographer whose research on growth rings in ancient bristlecone pine trees allowed him to develop Carbon 14 calibration, or “correcting scale.” This scale helped to resolve problems in radiocarbon dating in archaeology. Dr. Michael also published a number of works translated from Russian on various aspects of Arctic archaeology and ethnography, along with folklore of Arctic people. Holdings include research and field notes on his trips to the White Mountains in California to collect bristlecone pine samples, testing of wood samples at the Penn Museum Radiocarbon Lab, and notes and drafts of publications and translations.

MASCA- Stuart Fleming Records, 1975-2009 (inclusive)

Extent:
20.0 linear foot
Abstract:
MASCA, or the Museum Applied Science Center for Archaeology, was established in 1961 by a grant from the National Science Foundation. MASCA was modeled after the Research Laboratory for Archaeology and the History of Art in Oxford. From the time of its inception in 1961, MASCA, along with the Radiocarbon Laboratory, made a number of contributions to radiocarbon dating and other dating and materials analysis techniques including thermoluminescence, xeroradiography, Proton Induced X-ray Emission (PIXE) analysis of metals, analysis of faunal and plant remains and other projects either within the museum or remotely at archaeological sites. MASCA was disassembled in 2009.
