Josef Mengele—Simon Wiesenthal

The relationship between Josef Mengele and Simon Wiesenthal was not a direct personal contest so much as a pursuit shaped by distance, uncertain information, and competing accounts of the fugitive’s whereabouts. After the trial and execution of Adolf Eichmann, Wiesenthal devoted much of his energy to tracking Mengele. Yet his practical knowledge of the fugitive’s location was limited, and he filled that gap with stories that magnified the danger and reach of the man he wanted the world not to forget. The result was a consequential tension: Wiesenthal helped keep attention on Mengele’s crimes, while his dramatic accounts blurred the boundary between documented pursuit and legend.

The Pursuer and the Fugitive

Wiesenthal’s pursuit arose from a life marked by the destruction of his family and community. His family came from Galicia and was exterminated during the Holocaust; he was its lone survivor. After the war, he began collecting information about Nazi war criminals, first in Linz and then in Vienna, where he established the Jewish Documentation Centre. His work was both investigative and public: he campaigned against allowing West Germany to impose a statute of limitations on fugitives, and he made the continued pursuit of Nazi criminals a matter of international attention.

His public standing rested partly on a compelling account of himself as a determined hunter. After his autobiography, I Hunted Eichmann, appeared, Wiesenthal became an international figure. The book claimed a more decisive role for him in Eichmann’s capture than he had actually played. The book’s version of the pursuit therefore obscured the work of others: Fritz Bauer’s groundwork remained secret, while Mossad’s agents were bound by strict confidentiality. That earlier discrepancy forms an important backdrop to Wiesenthal’s later pursuit of Mengele, in which the public narrative again became larger and more certain than the available information.

Wiesenthal’s Viennese office, with a map of concentration camps on its wall, became an emblem of his work. He received death threats there and was widely seen, especially in America, as a solitary avenger. The book presents him not only as a tireless campaigner but as an exceptionally skilled storyteller and media operator. That ability helped keep the crimes of Auschwitz in public view; it also gave his accounts of Mengele’s escape a reach that the underlying intelligence did not necessarily warrant.

A Pursuit Built on Uncertain Information

Once Eichmann had been tried and executed, Wiesenthal redirected much of his energy toward Mengele. The pursuit unfolded amid a larger international effort. Hermann Langbein gathered evidence and pressed for legal action; a prosecutor in Freiburg im Breisgau issued an arrest warrant in 1959. West German authorities later made public claims about Mengele’s Paraguayan citizenship and presence in the tri-border region, while Mossad director Isser Harel considered a plan to capture him after Eichmann’s abduction. These efforts had different sources, methods, and degrees of access. Wiesenthal’s accounts became especially prominent, but the book emphasizes that his network was failing and that he had little reliable knowledge of where Mengele had gone to ground.

That uncertainty did not lead Wiesenthal to let the subject disappear from public attention. He kept describing Mengele as a fugitive who could not safely be left alone, and he circulated accounts that made him seem capable of slipping through every net. The claims were not merely reports of verified movements: the narrative describes Wiesenthal as embroidering unlikely stories to sustain interest in the hunt. This distinction matters to the relationship. Mengele was a real fugitive whose crimes warranted pursuit; Wiesenthal’s public portrait, however, also turned him into a near-mythic adversary.

The Stories and Their Dramatic Form

In July 1967, Wiesenthal published The Murderers Among Us, dedicating a chapter to Mengele under the title The Man Who Collected Blue Eyes. The chapter used a story about a Mossad agent allegedly murdered in Bariloche. In Wiesenthal’s version, the attractive blonde agent had been sterilised at Auschwitz by Mengele; years later, he recognized her by the tattoo on her arm while they danced and forced her over a precipice on a mountain path. The book presents this episode as an appropriation and elaboration of an existing story, not as established evidence of an encounter.

Wiesenthal’s wider portrait made Mengele a restless international traveler. He claimed to hunt him in Peru, Chile, Brazil, and remote Paraguayan army camps; in this account Mengele had bodyguards, drove a powerful black Mercedes, and frequented the best restaurants in Asunción. Another episode sent Mengele with Martha by yacht toward the Greek island of Kythnos after Gamal Abdel Nasser denied him entry to Egypt. A journalist sent to investigate was told by the manager of the Unique Hotel that a German man and his wife had left the day before on a sailing boat for an unknown destination. Wiesenthal presented the departure as another escape. Taken together, these episodes made the fugitive appear at once visible everywhere and impossible to locate.

The most elaborate escape story concerned an alleged raid by Auschwitz survivors calling themselves the Committee of Twelve. Wiesenthal placed it at the Hotel Tirol in Encarnación on a hot night in March 1964. In his account, the group stormed room twenty-six only to find the bedding still warm; Mengele, warned by telephone, had fled into the jungle in his pyjamas ten minutes earlier. The episode gave the fugitive a near-supernatural instinct for danger. The book’s account identifies it as part of the legend Wiesenthal helped construct, rather than confirming that the raid and escape occurred as described.

The Hidden Location and the Growing Legend

Wiesenthal withheld the location he claimed for Mengele until the end of his 1967 book. He placed him in a military zone between Puerto San Vincente, on the Asunción–São Paulo highway, and Fortress Carlos Antonio López on the Paraná River. The reported refuge was a small white hut in jungle landscaped by German immigrants. According to the account, two roads led to it, both patrolled by soldiers and police; four armed bodyguards with radios and walkie-talkies watched over Mengele, paid for at his own expense. The specificity of this description supplied a dramatic answer to the question of how the fugitive could remain beyond reach, even as the book shows that Wiesenthal’s actual information was scant.

The public mystery had consequences beyond the page. In 1967, while stories of Mengele’s ubiquity circulated, the fugitive was living in hiding in Serra Negra and worrying about reports that the hunt had narrowed to Paraguay. He wondered whether those reports were a diversion, comparing them with the false Kuwait reports that had accompanied Mossad’s planning for Eichmann’s capture. This contrast places Wiesenthal’s public accounts within Mengele’s own anxious experience: even uncertain claims could feed his fear of exposure, without proving that the locations or escapes in those accounts were true.

The legend continued to grow. By 1985, claims placed Mengele in Paraguay, Chile, Bolivia, Uruguay, and even New York; other stories recast him as a drug-trafficking baron or linked him to the proliferation of twins in southern Brazil. The book connects this atmosphere to Wiesenthal’s persistent role in keeping the hunt alive, while distinguishing the circulation of sensational allegations from reliable identification of the fugitive. When Brazilian authorities announced the discovery of remains believed to be Mengele’s, Wiesenthal remained unconvinced. He counted this as the seventh reported death of the war criminal, after earlier claims from the Russian front, Paraguay, Brazil, Bolivia, and Portugal.

Significance of the Relationship

Wiesenthal’s pursuit was driven by a public obligation to remember and expose the crimes of Auschwitz, but his relationship to Mengele also became a contest over who could define the fugitive’s story. The legal investigations and intelligence operations depended on evidence, jurisdiction, and secrecy; Wiesenthal’s public campaign worked through visibility, narrative, and sustained attention. The two modes were not equivalent. The book credits his advocacy and media skill with keeping the hunt in public consciousness, while showing that the stories he amplified could outrun what he knew.

That tension gives the relationship its lasting significance. Wiesenthal made it harder for Mengele’s crimes to recede from public memory, but his image of the fugitive as a globe-spanning escape artist also transformed a poorly located criminal into a figure of legend. The pursuit therefore has two histories at once: an effort to bring a war criminal to justice, and a public narrative whose dramatic escapes repeatedly obscured the limits of the evidence.
