[email protected]. American Scientists, Americanist Archaeology: The Committee on Radioactive Carbon 14 by Keith David Baich A thesis submitted in partial fulfillment of the requirements for the degree of Master of Arts in History Thesis Committee: Richard H. Beyler, Chair Kenneth M. Ames Katrine Barber David A. Johnson Portland State University ©2010 Abstract Willard Libby’s development of carbon-14 dating at the University of Chicago immediately following World War II provided an unprecedented opportunity for the collaboration of archaeologists with a physical chemist. Libby’s need for archaeological samples to test the dating process (1947-1951) meant that he relied upon the Committee on Radioactive Carbon 14, formed by the American Anthropological Association, for datable materials, as well as for assistance in all other archaeologically related aspects of the testing phase. The committee, under the leadership of archaeologist Frederick Johnson, served the mandated function of providing assistance to Libby, but simultaneously endeavored to utilize the new dating method to promote the development of the authority of anthropological professional organizations and further establish Americanist archaeology in a national and global context.
