Dr. C. Timothy McKeown is a legal anthropologist whose career has focused exclusively on the development and use of explicit ethnographic methodologies to document the cultural knowledge of communities and use that knowledge to enhance policy development and implementation. He has been intimately involved in the documentation and application of indigenous knowledge to the development of U.S. repatriation policy since 1991. For 18 years he served as a Federal official responsible for drafting regulations implementing Native American Graves Protection and Repatriation Act (NAGPRA), developing databases to document compliance, establishing a grants program, investigating allegations of failure to comply for possible civil penalties, coordinating the activities of a Secretarial advisory committee, and providing training and technical assistance to nearly 1000 museums and Federal agencies and 700 indigenous communities across the U.S. The results of his regulatory drafting have withstood broad public review by all constituencies as well as direct challenges in Federal District and Appellate Courts. He advised or served as part of U.S. delegations negotiating repatriation provisions before the International Institute for the Unification of Private Law (UNIDROIT), Organization of American States, and United Nations Commission on Human Rights. Since 2009, Tim has consulted on repatriation of cultural items with several Indian tribes, the National Association of Tribal Historic Preservation Officers (NATHPO), and served as an expert witness for tribal Plaintiffs in a case before a US Federal District Court. In 2020, the U.S. Secretary of the Interior appointed Tim to the seven-person Native American Graves Protection and Repatriation Review Committee where he was elected to serve as the committee's vice chair. In 2024, NATHPO honored Tim as a Partner in Preservation for his long-standing pro bono service as the association's repatriation advisor.
