The Historical Archaeology Sanatorium Project focuses on tuberculosis sanatoria in California during the early twentieth century. This project investigates issues related to disability, stigma, health, identity, and archaeologies of institutions in order to understand social aspects of health and disease. The Weimar Joint Counties Sanatorium was originally a government operated tuberculosis hospital for patients who were unable to pay for treatment elsewhere. The Weimar Joint Sanatorium was jointly operated by up to fifteen counties in California, and it was opened in 1919, transitioned to a general medical center in the 1950s, and closed in 1972. TB sanatoria were long term resident health facilities where patients would live for several months or years. The Weimar Joint Sanatorium was also part of a wider health landscape, and the town of Colfax had at least six privately operated sanatoria. During 2019, I completed oral history research and archival research in the Colfax and Weimar Area. I recorded new oral histories and searched the existing oral history collections at the Colfax Area Historical Society and the Placer County Archives. Through these oral histories, I learned about the daily practices at the sanatoria, experiences of living at or near the sanatoria, and the landscape surrounding these institutions. Archival research included studying board meeting notes, sanatorium magazines, newspaper articles, and photographs. I also consulted libraries and archives in Sacramento to gain a better understanding of the development of public health systems in California at the state and local level.
