HX02 Skin at the service of atrocity: dermatology, human experimentation and ethics in Nazi Germany

Abstract

During the Nazi regime, knowledge relating to the skin was systematically distorted to justify inhumane experimentation. Archival documents, contemporaneous publications and transcripts from the Nuremberg Doctors’ Trial reveal how concepts central to dermatology were repurposed to serve ideological, racial and military objectives. Prisoners at Dachau were subjected to freezing conditions in experiments investigating hypothermia and frostbite. Topical preparations were applied to assess their effects on skin exposed to extreme cold. Reported outcomes include severe necrosis, systemic collapse and death. Expert analysis presented at Nuremberg demonstrated that these experiments lacked defined protocols or reproducible methodology. At Ravensbrück, physicians Karl Gebhardt and Herta Oberheuser conducted wound infection experiments in which prisoners’ limbs were deliberately incised, inoculated with bacteria and contaminated with foreign materials to simulate battlefield wounds and assess sulfonamide therapy. Trial records describe inadequate analgesia, and postoperative neglect. Dermatology also intersected with Nazi racial science. Josef Mengele conducted comparative observation of phenotypic traits, including skin and eye pigmentation, hair colour and texture, in support of Nazi racial hierarchies. He also developed a particular interest in noma (cancrum oris), a gangrenous disease of the face rare in Europe prior to the war. Affected Roma children were killed by injection to permit post mortem pathological examination. Under racial legislation, Jewish physicians were dismissed from academic and hospital posts, excluded from professional societies and later prohibited from treating non-Jewish patients. Of 566 Jewish dermatologists practising in Germany in 1933, less than half were able to emigrate, and only a small number survived within Nazi Germany. Taken together, these cases reveal a consistent pattern in which knowledge of the skin was stripped of its ethical foundations and repurposed for ideological coercion. This history underscores our enduring responsibility to uphold patient welfare and scientific integrity – lessons directly relevant to contemporary medical ethics.
