Medical collaboration with authoritarian regimes historically has served to facilitate the use of torture as a tool of repression and to justify atrocities with the language of public health. Because scholarship on medicalized killing and biomedicalist rhetoric and ideology is heavily focused on Nazi Germany, this article seeks to expand the discourse to include other periods in which medicalized torture occurred, specifically in Argentina from 1976 to 1983, when the country was ruled by the Proceso de Reorganización Nacional military regime. The extent to which medical personnel embedded themselves within the Proceso regime's killing apparatus has escaped full recognition by both scholars and human rights activists. This article reconstructs the narrative of the Proceso's human rights abuses to argue that health professionals knowingly and often enthusiastically facilitated, oversaw, and participated in every phase of the "disappearance," torture, and mass murder process.
