Josef Mengele—Wolfgang Gerhard

The relationship between Josef Mengele and Wolfgang Gerhard was a practical alliance of ideological commitment and concealment. Gerhard arranged Mengele’s move into Brazil, created the cover under which he could live at an isolated farm, and served as his principal connection to the outside world. The arrangement offered refuge, but it also concentrated knowledge of Mengele’s whereabouts in a protector whom investigators could follow.

A Protector in the Escape Network

Gerhard entered Mengele’s life through Uli Rudel, who contacted him after deciding to move the fugitive from Paraguay into Brazil. Gerhard was Rudel’s São Paulo representative for Kameradenwerk, part of a wider network that could provide contacts and assistance to former Nazis. The move therefore depended not only on a personal bond but on links among committed supporters across national borders.

Mengele’s family in Günzburg initially doubted Gerhard’s reliability. He had struggled financially since leaving Austria in 1949, and they questioned whether he might charge heavily or prove untrustworthy. Rudel reassured them that Gerhard would ask for no payment: protecting a fugitive of Mengele’s standing was, for him, an ideological commitment. Gerhard’s Nazi allegiance was not incidental to the arrangement. He published propaganda and antisemitic material, and his household displayed Nazi symbolism, details that help explain why he treated the undertaking as a duty rather than a commercial opportunity.

From São Paulo to the Stammer Farm

Before finding Mengele a place to hide, Gerhard employed him in his confectionery shop when he first arrived in Brazil. He offered encouragement and reassurance, treating him, in the account’s description, almost like a son. That care came with a substantial personal cost: Gerhard put his business and family life behind his efforts to protect Mengele. The relationship thus combined practical assistance with an intense sense of political purpose.

Gerhard then drove Mengele north from Itapecerica in a modest Ford Anglia toward an isolated farm near Nova Europa, roughly 300 kilometres from São Paulo. The destination belonged to Geza and Gitta Stammer, Hungarian emigrants whom Gerhard had met among Central European expatriates. He had assessed them as politically dependable and unlikely to expose the fugitive.

To secure their cooperation, Gerhard presented Mengele as Peter Hochbichler, a Swiss livestock-breeding specialist in his fifties seeking companionship and farm work. The cover story also supplied a financial rationale: Hochbichler had recently inherited money and wanted to invest in land. As Geza was often away on surveying work, the supposed specialist could manage the farm. The Stammers were not wealthy; they agreed to provide food, lodging, and concealment, but not wages. Gerhard’s account made the arrangement appear mutually useful while withholding the central fact of the guest’s identity.

Care, Secrecy, and Routine

At the farm, Gerhard remained the crucial intermediary. Mengele saw no one other than him, and Gerhard brought newspapers, books, laxatives, and occasional classical music records. The flow of these ordinary provisions made the refuge livable while preserving the fugitive’s isolation. Mengele was known within the household as Uncle Peter, an eccentric Swiss man who was not to be photographed or discussed beyond the farm.

Gerhard’s role also involved managing access. Before the Stammers received visitors, Mengele questioned them about who was coming, where the visitors were from, and how long they had been known. Even when reassured, he stayed out of sight. On Saturdays, when the Stammer children’s friends visited, he withdrew as soon as they had greeted the guests. These precautions belonged to the same protective arrangement Gerhard had initiated: the farm offered cover only so long as the people around it observed its rules of silence.

The relationship’s imbalance is evident in the way Gerhard subordinated his own household to the task. His work, wife, and children became secondary during the year of his involvement. For Mengele, who was increasingly anxious about recognition and capture, Gerhard supplied both material support and repeated reassurance. The protection was personal in its daily execution, but it rested on shared ideological commitments and a larger network of willing accomplices.

The Protector Becomes a Trace

Gerhard’s importance also made him a point of vulnerability. By the spring of 1962, Willem Sassen, seeking money, disclosed to Mossad that Mengele had fled to Brazil and identified Gerhard as the fugitive’s protector and sole contact with the outside world. Mossad agents began following Gerhard. One morning, his Ford Anglia travelled into the savannah toward the isolated farm, giving investigators a route to the place where Mengele was hidden.

Zvi Aharoni and two agents went near the farm under the pretext of a picnic. Three men came to meet them; one, wearing a hat and keeping apart from the conversation, appeared to Aharoni to be Mengele. The identification still required photographic confirmation, so the agents did not immediately act. The episode shows the double edge of Gerhard’s role: his reliability had helped keep Mengele hidden, but his movements could lead pursuers toward the refuge.

Significance of the Relationship

Gerhard was more than a driver or caretaker. He arranged employment, transport, a false identity, a host household, and continuing supplies, turning ideological loyalty into a working system of concealment. His relationship with Mengele illustrates how a fugitive’s safety could depend on a succession of intermediaries rather than on any single hiding place. Yet the same dependence produced a trail: once Gerhard was identified and followed, the secrecy surrounding the farm became less secure. The alliance sustained Mengele’s life in hiding while exposing the human connections on which that concealment depended.
