1916–1968
An archaeologist and anthropologist with a deep interest in California’s Indigenous past, he wrote clearly about fieldwork, local history, and the material traces people leave behind. His books and reports still reflect a practical, curious mind shaped by years of research and teaching.

by Adan E. (Adan Eduardo) Treganza, Agnes Bierman
Born in Salt Lake City on December 27, 1916, Adán Eduardo Treganza became an American anthropologist and archaeologist best known for his work on California archaeology and Native history. Memorial notices published after his death describe a career centered on field research, teaching, and public lectures, especially on California Indians and archaeology.
He was closely associated with San Francisco State College, where he served as chair of the anthropology department until illness forced his resignation shortly before his death in 1968. His name remained closely tied to the university through the Adan E. Treganza Anthropology Museum, a sign of the lasting impression he made on the school’s anthropology program.
As an author, Treganza wrote and contributed to works such as The Topanga Culture: Final Report on Excavations, 1948, Fort Ross: A Study in Historical Archaeology, and other archaeological surveys and salvage reports. His writing grows out of hands-on investigation, making it especially appealing to listeners interested in Western history, archaeology, and the stories hidden in landscapes and artifacts.
