Renewed Hunt for Mengele in 1985
The Disappearance of Josef MengeleThe Renewed Hunt for Mengele in 1985 turned survivor testimony, scattered documentary clues, and years of frustrated pursuit into a coordinated international search. The campaign exposed the contrast between the expanding public demand for accountability and the private networks that had helped Josef Mengele remain hidden. It also ended the long-running uncertainty over where investigators should look: evidence gathered in Germany led them to Brazil, and ultimately to the grave where he had been buried under another name.
The Pursuit Before 1985
The renewed effort followed decades in which legal action repeatedly met delay, jurisdictional obstacles, and political obstruction. Hermann Langbein, a survivor of Dachau and Auschwitz and co-founder of the International Auschwitz Committee, began investigating Josef Mengele after noticing his divorce announcement. He assembled evidence and pressed West German authorities to act. Although the federal justice minister deferred the case to a regional court and most judges declined to proceed, a prosecutor in Freiburg im Breisgau issued an arrest warrant on 25 February 1959, charging multiple cases of premeditated murder and attempted murder. Langbein also argued that the West German government should seek extradition from Argentina, where he believed Josef Mengele lived.
The pursuit acquired international urgency after the capture of Adolf Eichmann. On 20 June 1960, a warrant was issued for Josef Mengele, while journalists and investigators converged on Buenos Aires. The warrant did not promptly bring him to trial: the account describes Lothar Hermann as wrongly accused of being the Auschwitz doctor. Meanwhile, the West German government faced pressure to demonstrate that it was not shielding Nazi criminals. Josef Mengele’s flight to Paraguay and his Paraguayan citizenship complicated efforts to reach him. In 1962, West Germany requested his extradition, but President Stroessner refused to cooperate; a later offer of aid in exchange for his delivery did not change Paraguay’s position.
Investigators had reasons to suspect that he had moved on. In 1964, West German officials publicly described him as a Paraguayan citizen living near the tri-border area and traveling to Brazil. Yet their search remained constrained: the authorities sent no agents or spies, and their intelligence services included former Nazis. Paraguay’s government insisted on protecting its citizens and rejected West German interference. Even the revocation of Josef Mengele’s Paraguayan citizenship in 1979 did not settle the question of his whereabouts. The old arrest warrant, the uncertain trail, and the history of official reluctance formed the backdrop to the 1985 campaign.
Survivors Make the Case Public
The immediate impetus came from survivors who gathered at Auschwitz on 27 January 1985, the fortieth anniversary of the camp’s liberation. Among them were people who had been subjected to Josef Mengele’s experiments, including twins and people with dwarfism or disabilities. They appealed publicly for governments to find him and bring him to justice. Their testimony made the search more than a matter of locating a fugitive: it placed the consequences of his crimes before an international audience.
On 4 February, a mock trial was held at Yad Vashem in Jerusalem. The tribunal included the chief prosecutor from the Jerusalem trial of Adolf Eichmann, Simon Wiesenthal, and the chief US military counsel from the Nuremberg war crimes trial. Over three days, former prisoners described the medical experiments and abuse they had endured. Their accounts included experiments involving twins and newborns, presented without the distance or abstraction of Josef Mengele’s own postwar rationalizations. The testimony gave renewed force to the demand for his arrest and helped prompt the US attorney general to call for a review of the complete file before the mock trial had even concluded.
The proceedings also challenged Josef Mengele’s claims about his work. At Auschwitz, he had overseen painful examinations of twins and the collection of human organs for transmission to the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics. Miklós Nyiszli’s account described his sustained attention to research and to the dossiers he kept on the twins, even late in the war. Years later, when his son Rolf asked what he had done at Auschwitz, Josef Mengele defended his actions as military and scientific duty, presenting selection and murder as impersonal necessities. The survivors’ testimony, by contrast, restored the individual victims and the violence obscured by that defense to the center of public attention.
An International Search Takes Shape
Two days after the mock trial opened, on 8 February, Israel announced that it would resume the hunt and offered a reward of one million dollars. The Simon Wiesenthal Center and the Washington Times each added a million dollars, while West Germany offered one million marks. The book gives the total value of the rewards as $3.4 million. The scale of the bounty signaled a new level of cooperation: American, Israeli, and West German authorities began sharing information and coordinating their efforts.
The US investigation drew on the Office of Special Investigations, established by the Carter administration to pursue Nazi criminals in the United States, and on the resources of the CIA, the National Security Agency, and the Department of Defense. The case also received intense attention from journalists and adventurers, who traveled to Günzburg and South America. That publicity helped amplify the demand for justice, but it also circulated speculation about Josef Mengele’s location. He was still widely believed to be alive, yet the public search was, without the investigators’ knowledge, already pursuing a dead man.
The German Network and the Trail to Brazil
A decisive break came from within Josef Mengele’s circle. In autumn 1984, Hans Sedlmeier told an acquaintance during a holiday dinner in the Black Forest that he had never stopped sending money to Josef Mengele. The information reached the police, who obtained authority to search his home. On 10 May 1985, a German prosecutor alerted American and Israeli partners that a search was pending. This time, Günzburg police did not warn the person under investigation.
At the end of May, police searched Sedlmeier’s villa and seized an address book, coded telephone numbers, and photocopied correspondence involving Josef Mengele, Wolfram Bossert, and the Stammer family. A letter from Wolfram Bossert reported Josef Mengele’s death. Sedlmeier refused to cooperate and was placed under house arrest while investigators worked through the coded contacts. The address book led them to Brazil. São Paulo police watched the Bossert and Stammer families around the clock for four days, without finding Josef Mengele.
On 5 June, police raided the Bosserts’ home. They found belongings and recent photographs that confirmed the family’s connection to Josef Mengele. Wolfram Bossert then told them that Josef Mengele was dead and buried in a cemetery in Embu under the name Wolfgang Gerhard. Gitta Stammer recognized the man in a photograph but identified him as Peter Hochbichler, the Swiss manager of the family’s farms, whom Wolfgang Gerhard had introduced to them. She denied knowing Josef Mengele. Her husband, Geza Stammer, was away on a cruise in Asia and was not questioned at that time.
Discovery and Significance
The news of the discovery reached the press before the investigation had run its course. On 6 June, reporters and cameras gathered at the cemetery in Embu das Artes as police exhumed the grave associated with Wolfgang Gerhard. The remains gave physical form to what the international hunt had not yet known: the elusive fugitive was no longer alive. The public search had been driven by the belief that he might still be found in Paraguay, Uruguay, or elsewhere in South America; the German correspondence and the Brazilian grave instead revealed how his concealment depended on continued personal support and an assumed identity.
The 1985 campaign therefore achieved two things at once. Survivor testimony renewed the moral and political pressure to prosecute Josef Mengele, while patient investigative work uncovered the networks that had sustained his escape. The mock trial could not itself bring him before a court, and the international manhunt could not arrest a man already dead. But the search traced the connections between his family’s circle, Sedlmeier’s financial assistance, and his refuge in Brazil, turning decades of rumor into evidence and bringing the fugitive story to a close.
