Mengele conducted experiments to change eye color by injecting dyes into the eyes of his subjects. Persons with heterochromatic eyes – meaning the two eyes are of differing coloration – Mengele had executed. The eyes were then removed and shipped off for further studies, usually to researchers in Berlin.
Mengele performed several experiments on dwarfs and children with abnormalities, usually including unnecessary medications and charting of the entire body with x-rays before killing them, dissecting the body, and sending the skeletons, organs, and all of the collected data to Berlin.
Not all of Mengele’s crimes were confined to the laboratory. Eyewitness testimony following the liberation of Auschwitz included other tales of horror. One witness described Mengele killing an infant by tossing it off of the roof of a camp building. Victims who refused to submit to his demands that they submerge themselves in nearly boiling water were summarily shot, to be immediately replaced by another inmate.
Mengele used prisoners to test the efficacy of anti-burn medications by first inflicting phosphorous burns on their bodies. Wounds were inflicted on prisoners and then deliberately infected, in order to test potential battlefield antibiotics. Prisoners who recovered from the torment were then gassed. Some prisoners were denied water until nearly dead of thirst, then given only seawater, under the guise of developing recovery plans for shipwrecked sailors. Death was painful and carefully monitored and Mengele became known as the Angel of Death.
By late 1944, the Russian armies had advanced perilously close to the Auschwitz-Birkenau complex, and Mengele and many of his associates prepared to flee. Some of the Jewish doctors who had assisted him were gassed, others managed to survive by expressing the need to pursue further study. Some escaped in the rising chaos of the collapse of Germany. In January 1945 Mengele moved to another camp in Silesia, taking with him his few surviving records and notes which had escaped the SS attempts to destroy the evidence of what had transpired at Auschwitz.
The Soviet Army arrived at Auschwitz in late January 1945. About three weeks later Mengele was on the move again, fleeing the Gross-Rosen camp where he had arrived after Auschwitz and traveling westward across Germany. Mengele adopted the guise of an officer of the Wehrmacht, (the German military, not yet associated with the atrocities being unveiled by the Russians) and after leaving his notes and other documents with a friend, made for the advancing American Army. He was captured by the Americans in June 1945, after Germany’s surrender.
Mengele took advantage of the immediate post-war confusion and the lack of coordination between the allies to avoid being placed on a suspected war criminals list. Most of the documents which incriminated him in the crimes at Auschwitz-Birkenau had not yet come to light, and he was regarded by the Americans as a simple prisoner of war. Released in 1945 he obtained false identity documents using the name Fritz Hollmann.
Under that name, he wandered across post-war Europe, never staying long in one place and always wary of being identified. By then the stories of his activities in the camps were becoming known. Mengele eventually fled to the Soviet zone, in part because of an attempt on his part to reclaim his personal records of his activities in Auschwitz.
Mengele eventually found work and temporary hiding at an isolated farm near Rosenheim, remaining in hiding there until the spring of 1949. As the international pursuit of Nazi war criminals intensified, Mengele contacted former members of the SS who had established underground escape routes out of Europe, used to reach Argentina. There a large German community was known to harbor former officers and officials of the Third Reich.
Europe was a hotbed of intrigue and distrust between the former allies, and growing numbers of Germans (and others including the Vatican) assisted escaping former Nazis as part of resisting the domination of the Soviet Union on Eastern Europe. Many escape routes went through Italy, and Mengele used one of these, arriving in Genoa sometime in the summer of 1949. By August, he was on a ship to Argentina, traveling under an International Passport issued by the Red Cross as a war refugee, using the alias Helmut Gregor.
In Argentina Mengele found work as a salesman of farm implements and in that role traveled throughout the region, including frequent trips to Paraguay. He achieved access to family funds (his father had accumulated significant wealth) through Swiss banks and in the early 1950s invested in a carpentry company. At first, residing in a Buenos Aires apartment, Mengele later rented a house in Olivos, an affluent suburb, and evidence indicates that he soon resumed practicing medicine, in the form of performing illegal abortions.
By 1954 Mengele had obtained a West German passport with his real name and traveled to Switzerland for a ski vacation. Despite the efforts of West German police and the Israeli secret service, Mengele returned to live openly in Argentina, under his real name, protected from extradition by international law. He invested in a pharmaceutical company, purchased property, and according to evidence uncovered in the 1990s, resumed his experimental research on twins.
After moving to Paraguay, using the name Jose Mengele, the now remarried Mengele (his first wife had remained in Europe and divorced him) remained out in the open. During the Nuremberg Trials, his name and activities had been a common topic of testimony by accused Nazis and surviving prisoners, prompting legal action by the West Germans to extradite him to Europe to face a military tribunal. When Argentina was presented with extradition papers they rejected them out of hand, since Mengele was not a resident at the time the papers were prepared.
Mengele had lived well in Argentina, with family money (thanks to his father’s investments in Argentine industry) at his disposal. He was well-received by Argentine society, including being an occasional guest of Argentine President Juan Peron. When Peron was ousted in the mid-1950s Mengele’s influence began to wane, and the Nazi hunters closing in on him led him to flee to Paraguay, near the Argentine border.
Likely the event which was the greatest stimulus for his relocation was the seizure of fellow Nazi Adolf Eichmann, captured by the Israeli’s off of the streets of Buenos Aires and rushed out of the country before legal obstacles could be imposed. Mengele then reconsidered living openly and went underground.
Mengele adopted different aliases and identities over the next several years, moving often between Paraguay and Brazil, with frequent sojourns into Uruguay and Argentina. While residing undercover in the largely German community of Colonias Unidas on the Brazil-Paraguay border, Mengele made repeated trips to the Brazilian farm town of Candido Godoi.
The Brazilian town sheltered another large community of German refugees. Under the guise of working as a veterinarian, Mengele examined and treated cattle herds for various ailments. He also returned to attending pregnant women and began to inform the residents that he was capable of artificially inseminating cattle and humans, producing male twins as a result.
In subsequent interviews with those who remembered Mengele’s frequent visits, he was described as appearing to be an old-fashioned country doctor. He visited the patients, rather than the other way around. He treated livestock, family pets, and performed dental services, in addition to medical examinations and treatments, for the residents. Frequently his only compensation was an invitation to dinner.
The Boys From Brazil is a 1978 film which describes a fictional Nazi conspiracy in South America. The film presents unusual male children who bare physical resemblances to a youthful Adolf Hitler, and although there are several different Boys the similarities between them and Hitler – and each other – are unnerving. In the film, a total of 94 boys, all of whom are clones of Adolf Hitler, are produced.
The children are then sent to various locations around the world to be raised in a manner similar to Hitler’s childhood, in the hope that one will grow into a living replica. The project is masterminded by a fictionalized Josef Mengele operating out of Paraguay.
Beginning in 1963 and continuing into the 21st century a small town in Brazil experienced birth rates of twins of about one in five pregnancies, vastly exceeding the normal rate. The overwhelming majority of these births have been blue-eyed, with blond hair. An unusually large number have been boys. The town is Candido Godoi, which welcomed the disguised Mengele in the 1960s. Residents of the town have discussed the circumstances of Mengele’s visits. Many recalled that Mengele openly discussed artificial insemination of women to increase the odds of successful pregnancy.
In 1969 Mengele, still living under various identities and assumed names, purchased half interest in a farm in Brazil near Sao Paulo. In the early 1970s, he acquired the identity and papers of Wolfgang Gerhard and took up residence in a small house in the Eldorado section of Sao Paulo.
His son Rolf visited him there in 1977 and later reported his father to have no regrets over his career and his activities, other than the loss of much of his work. Mengele still feared pursuit by both the West Germans and the Israelis, although subsequent to his death it became known that the Israelis suspended attempts to capture the fugitive in 1962.
By the mid-70s Mengele’s health was in decline and he suffered from high blood pressure, leading to at least one stroke while in residence in Eldorado. In 1977 he visited friends in the Brazilian resort town of Bertioga.
While swimming in February 1979, Mengele suffered a stroke which caused immediate paralysis, leading to his death by drowning. Still using the identity of Wolfgang Gerhard, he was buried under that name.
Privately funded efforts such as those conducted by Simon Wiesenthal continued to search for the fugitive and supposed “sightings” of the living Mengele were reported all over the world. A reward of $100,000 for Mengele’s capture was offered in 1982, and the Israeli’s staged a mock trial of the Nazi doctor in 1985, which made his crimes again international news. In 1985, after research by the United States, Israeli, and West German experts and the help of uncounted private investigators, Mengele’s burial place, and false identity were revealed. Not until 1992 would DNA testing confirm the identity of Auschwitz’s Angel of Death.
Josef Mengele eluded pursuit for 34 years. To read of his unspeakable crimes, for which he never showed regret or remorse, is to realize the depths of depravity to which one man can sink. As one of history’s ironies, Mengele’s skeletal remains are in the possession of the medical school of the University of Sao Paulo, where they are used for medical training. They are deemed particularly useful in matching skeletal remains to the existing medical record for a given individual in forensic science courses.
