Revocation of Josef Mengele’s University Degree

The revocation of Josef Mengele’s university degrees was a rare formal repudiation of his professional standing: in early 1964, the universities of Frankfurt and Munich withdrew his doctorates in medicine and anthropology because of his crimes at Auschwitz concentration camp and his violation of the Hippocratic Oath. For Mengele, the loss was devastating not because it unsettled his account of what he had done, but because it discredited the scientific identity through which he had long understood and defended himself.

The Academic Identity Under Challenge

Mengele had made his work at Auschwitz concentration camp part of a self-image as a physician serving German medicine and protecting a racially defined community. In his own reasoning, the selection of prisoners and the elimination of those he deemed unfit belonged to a medical and national duty. That account converted violence into professional purpose: he represented himself as a guardian of racial health rather than as an agent responsible for the deaths and suffering inflicted on prisoners.

The record presented alongside that self-image makes the contradiction concrete. Miklós Nyiszli, a Jewish doctor forced to assist Mengele, described experiments on twins and people with dwarfism, including procedures carried out for comparative research that ended in their deaths. Organs were sent to the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics in Berlin. Nyiszli also recalled Mengele returning to the research room and carefully reviewing the twins’ files late in the war. The care devoted to documentation and research stood beside the coercion and fatal outcomes on which that work depended.

The Revocation in 1964

Early in 1964, while living in exile, Mengele learned of the universities’ decision in a letter from Martha Mengele. The withdrawal of both doctorates—medicine and anthropology—struck at qualifications he regarded as the crowning proof of his professional achievement. He saw himself as a surgeon and a promising researcher, and experienced their removal as a bureaucratic insult that rendered years of effort worthless. The universities, by contrast, connected his professional credentials to the conduct those credentials had not excused: murder at Auschwitz concentration camp and the breach of medical duty represented by the Hippocratic Oath.

His response turned the punishment into another occasion for self-exoneration. He burned Martha Mengele’s letter, left the plantation, and went into the jungle with his dogs. There he continued to defend the biological and racial assumptions that had shaped his work, blaming the Germany that had once encouraged such thinking for now repudiating him. He insisted to himself that a society organized around race and heredity had made his actions intelligible and that he had carried out a state mission. The degrees had been withdrawn; the moral conclusion he drew from that decision remained unchanged.

A Defense That Persisted

Mengele’s later explanations show how little the revocation altered his account of Auschwitz. When confronted by Rolf, he described selection as a way to preserve those capable of work and treated the deaths of others as an unavoidable consequence of war and camp policy. He shifted responsibility to orders and the system, denied personal wrongdoing, and presented his role as service to German science. He also dehumanized Jewish victims and rejected compassion as a meaningful obligation toward them. These were not admissions prompted by the loss of his credentials, but repetitions of the reasoning that had made his conduct appear, to himself, legitimate.

That defense belonged to a wider postwar landscape of denial and political nostalgia. In Buenos Aires, the Dürer men’s club looked toward a future Germany while rejecting the democracy imposed by the Allies; its members believed Nazism had not been repudiated and that accounts of crimes in the camps were widely disbelieved. Mengele’s effort to frame his actions as part of a socially sanctioned biological project echoed that setting. The revocation therefore challenged not only his private pride in his degrees but also the claim that professional science could be separated from the racial ideology and state violence it served.

Professional Sanction and Criminal Pursuit

The loss of the degrees was distinct from the criminal case against Mengele. On 25 February 1959, a prosecutor in Freiburg im Breisgau, where Mengele had last been registered in Germany, issued an arrest warrant on multiple counts of premeditated murder and attempted murder. After the capture of Adolf Eichmann, the hunt for Nazi war criminals drew renewed attention; a warrant for Mengele’s arrest was issued on 20 June in the ensuing period. These proceedings belonged to the pursuit of criminal accountability, while the universities’ action addressed his academic standing.

West German efforts to locate Mengele were hampered by limited resources and procedural delays, and Paraguayan authorities resisted cooperation while asserting the protection of their citizen. Against that uncertain pursuit, the universities’ decision was a clear institutional judgment about the incompatibility between Mengele’s crimes and the honors he had held. It did not, in the evidence presented here, amount to his capture or trial. Its significance lies instead in the direct reversal of a source of pride: the degrees through which he had claimed scientific legitimacy were formally withdrawn, even as he continued to insist that the underlying ideology and work had been justified.
