Post-war period

The Post-war period in the book is not a clean break with Nazi rule but a contested aftermath: perpetrators and institutions evade responsibility even as survivors, investigators, and public media make the crimes harder to suppress. The contrast runs from the denial of mass murder and Mengele’s self-exculpation to survivor testimony and renewed demands for his arrest.

Public Knowledge and Organized Denial

By the 1950s, books, articles, and films were bringing the extermination of European Jews to a wider audience. In 1956, Alain Resnais’s Night and Fog had a profound impact, although the West German government secured its removal from the official selection at the Cannes Film Festival in the name of Franco-German reconciliation. The Diary of Anne Frank was also growing in popularity. Public discussion increasingly named crimes against humanity, the Final Solution, and the murder of six million Jews.

That expanding recognition met deliberate denial. The Dürer men’s club rejected the figure of six million, put the number of Jewish victims at 365,000, and denied mass murder and the use of gas chambers. Willem Sassen and Eberhard Fritsch presented Adolf Eichmann as the man who could overturn what they called a lie and rehabilitate Germany and Nazism. They proposed that he explain the supposed “pseudo-final solution” in a book for Dürer Publishing. Eichmann welcomed the prospect: he was living anonymously in Argentina, doing modest work and tending animals, and saw a book as a chance to defend his reputation and return to public notice. The proposed account thus belonged not to a neutral inquiry into the past but to a campaign to recast it.

Crimes, Careers, and Evasion

The book sets the scale of Nazi violence against the language of professional duty that perpetrators used to justify it. During 1944, Miklós Nyiszli, a Jewish doctor forced to work under Mengele at Auschwitz, later recorded the selections, experiments, and killings he witnessed. His account was published in Hungary in 1946 and in France in 1961. Nyiszli describes Mengele making selections among arriving deportees and pursuing experiments on twins and other prisoners. The work was not separate from institutional science: human remains and specimens were sent to the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics in Berlin, where Otmar von Verschuer was director. The book’s juxtaposition of the research apparatus with the treatment of prisoners exposes the distance between claims of scientific purpose and the reality of coercion and murder.

Mengele’s postwar account to his son Rolf repeats that distance as a defense. He described his work at Auschwitz as military duty in the service of German science, claimed that selection saved lives, and presented the murder of those he deemed unable to work as unavoidable. He also invoked obedience, patriotism, and the idea that he had been only one part of a larger system. Rolf did not accept this explanation, but neither did he openly challenge his father during the conversation; he eventually turned away and stopped listening. The episode shows how an account of duty could be used to deny personal responsibility without erasing the speaker’s own role in the crimes.

The postwar record also includes professional and social reintegration. Early in 1964, Mengele learned by letter from Martha that the universities of Frankfurt and Munich had withdrawn his doctoral degrees in medicine and anthropology because of his crimes at Auschwitz and his violation of the Hippocratic Oath. He treated the loss as an attack on his standing and burned the letter. Elsewhere, the book describes former camp personnel and participants in the T4 programme who escaped prosecution and resumed careers, including senior figures in German research. Mengele knew that many had been reintegrated into family and civil life. That continuity, alongside the revocation of his degrees, makes the period’s reckoning uneven rather than complete.

Family Silence and the Fugitive Life

The Mengele family’s postwar position joined private loyalty to public risk. By 1971, the family business had become a multinational enterprise with more than two thousand employees and a turnover of millions of marks. According to the account, the family feared that the discovery of its close bond with Mengele would damage the company. Hans Sedlmeier testified under oath to an investigating judge that Mengele had no relationship with the family, had never worked for the company, and probably lived in Paraguay; he also claimed not to have seen him since an encounter at Buenos Aires airport more than a decade earlier. The testimony presents concealment as an active choice made in the shadow of a successful business, not simply as silence within a private household.

For Rolf, the family’s silence was bound up with his identity. After the kidnapping of Adolf Eichmann, he discovered from newspapers that the uncle who had entertained him with stories at the Hotel Engel was in fact his father, Mengele, an Auschwitz perpetrator. Raised by his mother, Rolf became a lawyer in Freiburg and separated himself from the Günzburg family circle. He opposed what he saw as the family’s solidarity, greed, and indifference to victims, and aligned himself with the political left and postwar protest. Yet his rejection of the family did not free him from the burden of his father’s name or resolve the conflict over whether to expose him to prosecution.

Eichmann’s capture in 1960 changed the conditions of exile for Nazi fugitives in South America. His abduction and transfer to Israel alarmed other Nazi war criminals, while journalists arrived in Buenos Aires and the search for them became more public. On 20 June, a warrant was issued for Mengele’s arrest. Sassen’s association with Eichmann also collapsed: suspected by his circle of betrayal, he sold recorded interviews to Life and European media before fleeing to Uruguay. The episode links exposure, commercial exploitation of testimony, and the disintegration of a postwar network that had offered its members protection and reassurance.

Testimony, Memory, and Renewed Pursuit

The public culture of remembrance widened further in the late 1970s. The 1978 television miniseries Holocaust brought the extermination of European Jews to millions of viewers, helped make the term “Holocaust” widely used, and encouraged survivors to speak publicly. The book also places this shift alongside the retirement of a generation of Nazi administrators and managers in Germany, the development of memorials in the United States, and Claude Lanzmann’s work on Shoah. The growing visibility of the past did not itself secure justice, but it changed the scale and setting of public demands for it.

On 27 January 1985, the fortieth anniversary of the liberation of Auschwitz, survivors gathered at the camp and called publicly for Mengele’s capture. On 4 February, a three-day mock trial was held at Yad Vashem in Jerusalem, with senior figures associated with the Eichmann trial and the Nuremberg proceedings presiding. Former prisoners, including twins, dwarves, and people with disabilities, testified about Mengele’s experiments and the treatment of families in the camp. Their accounts turned a fugitive’s crimes into a public record before international audiences. The United States attorney general called for a review of the case file, and the Simon Wiesenthal Center, the United States, Israel, and West Germany increased pressure and offered rewards for Mengele’s capture.

The book closes this period’s arc not with a trial of Mengele but with the contrast between intensified pursuit and continued uncertainty. By 1985, a host of competing claims placed him in different countries, while media and popular culture helped enlarge his reputation into a legend. The mock trial and the survivors’ testimony countered that myth with specific testimony; yet the man they sought remained elusive. The Post-war period is therefore defined by an unfinished contest over evidence and responsibility: denial and concealment endure, but they are increasingly confronted by records, public memory, and witnesses demanding judgment.
