Illness was a defining experience for Holocaust victims, yet their medical history is missing. This chapter studies the medical staff, patients, and diseases in the Theresienstadt ghetto. In examining medical care in extremis, it studies how the Central European Jewish doctors succeeded in providing comparably excellent healthcare and good medications for the inmates. However, the medical staff applied triage, separating “important” from “irrelevant,” that is elderly, patients. The chapter examines the mentality, experience, and gendered power mechanisms that characterized the medical staff; the agency of the doctors; and the hierarchies they assigned to patients. Finally, in exploring how the prisoner physicians made sense of Theresienstadt as a part of their medical careers, the chapter shows what kind of historical protagonists doctors are.
