Josef Mengele (German: [ˈjoːzɛf ˈmɛŋələ] ^ⓘ; 16 March 1911 – 7 February 1979) was a Nazi German Schutzstaffel (SS) officer and physician during World War II at the Russian front and then at Auschwitz during the Holocaust, where he was nicknamed the "Angel of Death" (German: Todesengel). He performed deadly experiments on prisoners at the Auschwitz II-Birkenau concentration camp, where he was a member of the team of doctors who selected victims to be murdered in the gas chambers.

Before the war, Mengele received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943. He was assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His experiments focused primarily on twins, with no regard for the health or safety of the victims. With Red Army troops sweeping through German-occupied Poland, Mengele was transferred 280 kilometres (170 miles) away from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, ten days before the arrival of the Soviet forces at Auschwitz.

After the war, Mengele fled to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, but fled to Paraguay in 1959 and later Brazil in 1960, all while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal, who wanted to bring him to trial. Mengele eluded capture in spite of extradition requests by the West German government and clandestine operations by the Israeli intelligence agency Mossad. He drowned in 1979 after suffering a stroke while swimming off the coast of Bertioga, and was buried under the false name of Wolfgang Gerhard. His remains were disinterred and positively identified by forensic examination in 1985.

Early life

Mengele was born into a Catholic family in Günzburg, Bavaria on 16 March 1911, the eldest of three sons of Walburga (née Hupfauer) and Karl Mengele. His two younger brothers were Karl Jr. and Alois. Their father was the founder of the Karl Mengele & Sons company (later renamed Mengele Agrartechnik), which produced farming machinery. In 1915, the company expanded and switched to producing military equipment such as specialized wagons for military transport and parts for deploying naval mines. Karl joined the Nazi Party in 1933 and the SS in 1935, primarily as a way to advance his career in local politics. He served as a district economic advisor, and was found during denazification proceedings after the Second World War to have not been a committed Nazi.

Mengele was successful at school and developed an interest in music, art, and skiing. In 1924, he joined the Greater German Youth League, a right-wing youth group, and remained a member until 1930, serving as leader of the local chapter from 1927. He completed high school in April 1930 and went on to study medicine at the University of Munich. (Munich is where the headquarters of the Nazi Party was located.) After two semesters, he switched to the University of Bonn, where he took his medical preliminary examination. In 1931, he joined Der Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung ('Storm Detachment'; SA) in 1934. He spent the summer of 1933 studying at the University of Vienna, and earned his PhD in anthropology from the University of Munich in 1935, studying for four years under Theodore Mollison, a physical anthropologist and proponent of the pseudoscience of scientific racism. Mengele's dissertation, titled Rassenmorphologische Untersuchung des vorderen Unterkieferabschnittes bei vier rassischen Gruppen ("Racial morphological study of the anterior segment of the mandible in four racial groups"), attempted to prove that measurements of the lower jaw could be used to make a determination of race.

In January 1937, he joined the Institute for Hereditary Biology and Racial Hygiene in Frankfurt, where he worked for Otmar Freiherr von Verschuer, a German geneticist with a particular interest in researching twins. As Verschuer's assistant, Mengele focused on the genetic factors that result in a cleft lip and palate, or a cleft chin. His thesis on the subject earned him a cum laude doctorate in medicine (MD) from the University of Frankfurt in 1937. In a letter of recommendation, Verschuer praised Mengele's reliability and his ability to verbally present complex material in a clear manner. In 1938, he hired him as a permanent assistant at his institute. As part of his duties, he assessed the racial heritage of applicants for the Aryan certificate, a document required before a person could qualify for government jobs or German citizenship.

On 28 July 1939, Mengele married Irene Schönbein, whom he had met while working as a medical resident in Leipzig. Their only child, a son they named Rolf, was born in 1944.

Military career

Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS) in 1938. He received basic training in 1938 with the Gebirgsjäger (mountain light infantry) and was called up for service in the Wehrmacht (Nazi armed forces) in June 1940, some months after the outbreak of World War II. He soon volunteered for medical service in the Waffen-SS, the combat arm of the SS, where he served with the rank of SS-Untersturmführer (second lieutenant) in a medical reserve battalion until November 1940. He was next assigned to the SS Race and Settlement Main Office in Poznań, where one of his assignments was evaluating candidates for Germanization.

At the end of 1940, Menegele was assigned to the engineering battalion of the 5th SS Panzer Division Wiking, first as an assistant medical officer and as primary medical officer from October 1941. His unit was sent to the Ulm area for training in April 1941 and were eventually sent to an area southeast of Lublin to await the commencement of Operation Barbarossa, the German invasion of the Soviet Union. The unit crossed into Ukraine on 30 June. On 2 July, the commander of the division's Westland Regiment was killed by a sniper. In response, members of the Wiking Division killed several thousand Jews. This was the beginning of a pogrom by the Wiking Division that continued into Zolochiv and nearby areas until 4 July. German historian Kai Struve estimates the total number of Jewish civilians killed by the Wiking Division in their first week of action during Barbarossa was 4,280 to 6,950 people.

Mengele was awarded the Iron Cross 2nd Class on 14 July for bravery. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with Von Verschuer, who had become director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.

Auschwitz

Selection of Hungarian Jews on the ramp at Birkenau, May/June 1944

In 1942, Auschwitz II-Birkenau, originally intended to house slave laborers, began to be used instead as a combined labour camp and extermination camp. Prisoners were transported there by rail from all over Nazi-controlled Europe, arriving in daily convoys. By July 1942, SS doctors were conducting selections where incoming Jews were segregated, and those considered able to work were admitted into the camp while those deemed unfit for labor were immediately murdered in the gas chambers. Those selected to be killed, about three-quarters of the total, included almost all children, women with small children, pregnant women, all the elderly, and all of those who appeared (in a brief and superficial inspection by an SS doctor) to be not completely fit and healthy.

In early 1943, Von Verschuer encouraged Mengele to apply for a transfer to the concentration camp service. Mengele's application was accepted and he was posted to Auschwitz, where he was appointed by SS-Standortarzt Eduard Wirths, chief medical officer at Auschwitz, to the position of chief physician of the Zigeunerfamilienlager (Romani family camp) at Auschwitz II-Birkenau. The SS doctors did not administer treatment to the Auschwitz inmates but supervised the activities of inmate doctors who had been forced to work in the camp medical service. As part of his duties, Mengele made weekly visits to the hospital barracks and ordered any prisoners who had not recovered after two weeks in bed to be sent to the gas chambers.

Mengele's work also involved carrying out selections, visiting the selection ramp even when he was not on duty in the hope of finding subjects for his experiments, with a particular interest in locating sets of twins. In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling. He was one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-based pesticide that was used for the mass killings in the Birkenau gas chambers. He served in this capacity at the gas chambers located in crematoria IV and V.

When an outbreak of noma—a gangrenous bacterial disease of the mouth and face—struck the Romani camp in 1943, Mengele initiated a study to determine the cause of the disease and develop a treatment. He enlisted the assistance of prisoner Berthold Epstein, a Jewish pediatrician and professor at Prague University. The patients were isolated in separate barracks. The treatment involved administering vitamins and antibiotics to afflicted children, who saw significant improvement. However, once he was satisfied that it was effective, he discontinued treatment, and the children immediately fell ill again. Several afflicted children were killed so that their preserved heads and organs could be sent to the SS Medical Academy in Graz and other facilities for study. This research was still ongoing when the Romani camp was liquidated and its remaining occupants murdered in 1944.

When a typhus epidemic began in the women's camp, Mengele cleared one block of six hundred Jewish women and sent them to be killed in the gas chambers. The building was then cleaned and disinfected and the occupants of a neighboring block were bathed, de–loused, and given new clothing before being moved into the clean block. This process was repeated until all of the barracks were disinfected. Similar procedures were used for later epidemics of scarlet fever and other diseases, with infected prisoners being murdered in the gas chambers. For these actions, Mengele was awarded the War Merit Cross (Second Class with swords) and was promoted in 1944 to First Physician of the Birkenau subcamp.

Human experimentation

Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for medical experimentation. His medical experiments showed no consideration for the victims' health, safety, or physical and emotional suffering. He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarves, and people with physical abnormalities.

Twin research was of particular interest to Mengele. One twin could serve as subject with the other as the control. Most of the twins he studied were children between the ages of two and sixteen; historian Nikolaus Wachsmann estimates Mengele may have studied as many as a thousand sets of twins. Some were actually siblings who passed themselves off as twins to avoid being killed. Miklós Nyiszli and others suggested that twin studies may also have been pursued to uncover strategies for 'racially desirable' Germans to produce more twins. A grant was later provided by the Deutsche Forschungsgemeinschaft ('German Research Foundation'), at the request of Von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau. Nyiszli, who was forced to work on Mengele's behalf due to his pathologist background, prepared specimens and performed autopsies for this laboratory.

Mengele's research subjects were better fed and housed than the other prisoners, and temporarily spared from the gas chambers. His research subjects lived in their own barracks, where they were provided with a marginally better quality of food and somewhat improved living conditions than the other areas of the camp. When visiting his young subjects, he introduced himself as "Uncle Mengele" and offered them sweets. A former Auschwitz inmate doctor said of Mengele:

He was capable of being so kind to the children, to have them become fond of him, to bring them sugar, to think of small details in their daily lives, and to do things we would genuinely admire ... And then, next to that, ... the crematoria smoke, and these children, tomorrow or in a half-hour, he is going to send them there. Well, that is where the anomaly lay.

In his twin experiments, Mengele generally ordered the twins to undertake weekly physical examinations. Nyiszli recalled one occasion where Mengele killed 14 twins in a single night, first by injecting evipan to induce sleep, and then injecting their hearts with chloroform.

Jewish children kept alive in Auschwitz for use in Mengele's research. They were liberated in January 1945.

Other experiments included forcing inmates to undergo unnecessary drug and X-ray treatments. Survivors were typically sent to the gas chambers within weeks. Their skeletons were sent to Berlin for further analysis.

In his 1986 book, Lifton described Mengele as sadistic, lacking empathy, and extremely antisemitic, believing the Jews should be eliminated as an inferior and dangerous race. He also believed that he was responsible for an unknown number of deaths via other experiments, lethal injections, beatings, and shootings.

Eye studies

Mengele carried out eye research and experiments at Auschwitz. Prisoners and inmate physicians testified that Mengele ordered inmate physicians to drop chemicals in the eyes of subjects. Although there has been speculation that Mengele was attempting to "Aryanize" prisoner eyes by making them blue with dyes or other chemicals, this idea has been rejected by historian David G. Marwell. He argues that this is not supported by evidence, and that Mengele would not be interested in a "cosmetic change" with "no genetic meaning". According to Marwell, Mengele was most likely administering adrenaline drops into the eyes of subjects while researching the condition heterochromia (color differences of the iris) as part of his collaboration with biologist and eugenicist Karin Magnussen, who carried out Reich-funded research on eye color at the Kaiser Wilhelm Institute for Anthropology in Berlin. Magnussen was testing whether "pharmacologically effective substances" or hormones such as adrenaline could alter pigmentation of the eyes of rabbits, as well as studying the anatomy of the eye and the genetics underlying heterochromia.

Mengele's collaboration with Magnussen also included compiling genealogical records and documenting eye characteristics of prisoners. He sent eyes removed from Auschwitz prisoners to her lab in Berlin for histological study. After the war, Magnussen stated she believed that the specimens were from prisoners who had died of natural causes. The inmate pathologist Nyiszli said that some of the samples were from the bodies of people who had been killed by lethal injection.

Marwell suggests that the side effects associated with adrenaline administration may have contributed to widespread confusion about these experiments:

If adrenaline was, in fact, the substance that Mengele introduced into children’s eyes, it is instructive to understand its side effects: rise in blood pressure, disturbance in heart rhythm, feeling of weakness, faintness, perspiration, shaking, and pallor. These symptoms would have been frightening, and not only for a small child, and it is understandable why twin survivors recall these experiments with such horror and dread. And it is also understandable why the motivation behind them has been so misunderstood.

Myths and rejected anecdotes

Some rumors regarding Mengele have been rejected or challenged by historians, including the claim that Mengele sewed two twins together to create conjoined twins. Agnieszka Kita, a historian at the Auschwitz-Birkenau State Museum, has described this as a myth. Historian David G. Marwell has rejected other rumors about Mengele, including the suggestion that he surgically "connected the urinary tract of a 7-year-old girl to her own colon", or that he attempted to "make boys into girls and girls into boys" using "cross transfusions", or that he attempted to change people's eye color.

After Auschwitz

Along with several other Auschwitz doctors, Mengele transferred to Gross-Rosen concentration camp in Lower Silesia on 17 January 1945, taking with him two boxes of specimens and the records of his experiments at Auschwitz. Most of the camp medical records had already been destroyed by the SS by the time the Red Army liberated Auschwitz on 27 January. Mengele fled Gross-Rosen on 18 February, a week before the Soviets arrived there, and traveled westward to Žatec in Czechoslovakia, disguised as a Wehrmacht officer. There he temporarily entrusted his incriminating documents to a nurse with whom he had struck up a relationship. He and his unit then hurried west to avoid being captured by the Soviets, but were taken prisoners of war by the Americans in June 1945. Although Mengele was initially registered under his own name, he was not identified as being on the major war criminal list due to the disorganization of the Allies regarding the distribution of wanted lists, and the fact that he did not have the usual SS blood group tattoo. He was released at the end of July and obtained false papers under the name "Fritz Ulmann", documents he later altered to read "Fritz Hollmann".

After several months on the run, including a trip back to the Soviet-occupied area to recover his Auschwitz records, Mengele found work near Rosenheim as a farmhand. He eventually escaped from Germany on 17 April 1949, convinced that his capture would mean a trial and death sentence. Assisted by a network of former SS members, he used the ratline to travel to Genoa, where he obtained a passport from the International Committee of the Red Cross under the alias "Helmut Gregor", and sailed to Argentina in July 1949. His wife refused to accompany him, and they divorced by proxy in Düsseldorf in 1954.

In South America

Mengele worked as a carpenter in Buenos Aires, Argentina, while lodging in a boarding house in the suburb of Vicente López. After a few weeks, he moved to the house of a Nazi sympathizer in the neighborhood of Florida Este. He next worked as a salesman for his family's farm equipment company, Karl Mengele & Sons, and in 1951 he began making frequent trips to Paraguay as a regional sales representative. He moved into an apartment in central Buenos Aires in 1953, used family funds to buy a part interest in a carpentry concern, and then rented a house in the suburb of Olivos in 1954. Files released by the Argentine government in 1992 indicate that Mengele may have practiced medicine without a license while living in Buenos Aires, including performing abortions.

After obtaining a copy of his birth certificate through the West German embassy in 1956, Mengele was issued an Argentine foreign residence permit under his real name. He used this document to obtain a West German passport using his real name and embarked on a trip to Europe. He met with his son Rolf (who was told Mengele was his "Uncle Fritz") and his widowed sister-in-law Martha, for a ski holiday in Switzerland; he also spent a week in his home town of Günzburg. When he returned to Argentina in September 1956, Mengele began living under his real name. Martha and her son Karl Heinz followed about a month later, and the three began living together. Josef and Martha were married in 1958 while on holiday in Uruguay, and they bought a house in Buenos Aires. Mengele's business interests now included part ownership of Fadro Farm, a pharmaceutical company. Along with several other doctors, he was questioned in 1958 on suspicion of practicing medicine without a license when a teenage girl died after an abortion, but he was released without charge. Aware that the publicity could lead to his Nazi background and wartime activities being discovered, he took an extended business trip to Paraguay and was granted citizenship there in 1959 under the name "José Mengele". He returned to Buenos Aires several times to settle his business affairs and visit his family. Martha and Karl lived in a boarding house in the city until December 1960, when they returned to West Germany.

Mengele's name was mentioned several times during the Nuremberg trials in the mid-1940s, but the Allied forces believed that he was probably already dead. Irene Mengele and the family in Günzburg also claimed that he had died. Working in West Germany, Nazi hunters Simon Wiesenthal and Hermann Langbein collected information from witnesses about Mengele's wartime activities. In a search of the public records, Langbein discovered Mengele's divorce papers, which listed an address in Buenos Aires. He and Wiesenthal pressured the West German authorities into starting extradition proceedings, and an arrest warrant was drawn up on 5 June 1959. Argentina initially refused the extradition request because the fugitive was no longer living at the address given on the documents; by the time extradition was approved on 30 June, Mengele had already fled to Paraguay and was living on a farm in Hohenau, near the Argentine border. Mengele reportedly worked as a veterinary surgeon under the alias of 'Francisco Fischer' while living in Hohenau, before leaving Paraguay for Brazil sometime in 1964. After a request from Paraguayan Attorney General Clotildo Jimenez, the Supreme Court of Paraguay annulled Mengele's citizenship in August 1979.

Efforts by Mossad

In May 1960, Isser Harel, director of the Israeli intelligence agency Mossad, personally led the successful effort to capture Adolf Eichmann in Buenos Aires. He was hoping to track down Mengele so that he too could be brought to trial in Israel. Under interrogation, Eichmann provided the address of a boarding house that had been used as a safe house for Nazi fugitives. Surveillance of the house did not reveal Mengele or any members of his family, and the neighborhood postman claimed that although Mengele had recently been receiving letters there under his real name, he had since relocated without leaving a forwarding address. Harel's inquiries at a machine shop where Mengele had been part owner also failed to generate any leads, so he was forced to abandon the search.

Despite having provided Mengele with legal documents using his real name in 1956 (which had enabled him to formalize his permanent residency in Argentina), West Germany was now offering a reward for his capture. Continuing newspaper coverage of his wartime activities, with accompanying photographs, led Mengele to relocate again in 1960. Former pilot Hans-Ulrich Rudel put him in touch with the Nazi supporter Wolfgang Gerhard, who helped Mengele cross the border into Brazil. He stayed with Gerhard on his farm near São Paulo until a more permanent accommodation could be found, which came about with Hungarian expatriates Géza and Gitta Stammer. The couple bought a farm in Nova Europa with the help of an investment from Mengele, who was given the job of managing for them. The three bought a coffee and cattle farm in Serra Negra in 1962, with Mengele owning a half interest. Gerhard had initially told the Stammers that the fugitive's name was "Peter Hochbichler", but they discovered his true identity in 1963. Gerhard persuaded the couple not to report Mengele's location to the authorities by convincing them that they themselves could be implicated for harboring a fugitive. In February 1961, West Germany widened its extradition request to include Brazil, having been tipped off to the possibility that Mengele had relocated there.

Meanwhile, Zvi Aharoni, one of the Mossad agents who had been involved in the Eichmann capture, was placed in charge of a team of agents tasked with tracking down Mengele and bringing him to trial in Israel. Their inquiries in Paraguay revealed no clues to his whereabouts, and they were unable to intercept any correspondence between Mengele and his wife Martha, who by this time was living in Italy. Agents who were following Rudel's movements also failed to produce any leads. Aharoni and his team followed Gerhard to a rural area near São Paulo, where they identified a European man whom they believed to be Mengele. This potential breakthrough was reported to Harel, but the logistics of staging a capture, the budgetary constraints of the search operation, and the priority of focusing on Israel's deteriorating relationship with Egypt led the Mossad chief to call off the manhunt in 1962.

Later life and death

In 1969, Mengele and the Stammers jointly purchased a farmhouse in Caieiras, with Mengele as half owner. When Wolfgang Gerhard returned to Germany in 1971 to seek medical treatment for his ailing wife and son, he gave his identity card to Mengele. The Stammers' friendship with Mengele deteriorated in late 1974, and when they bought a house in São Paulo, he was not invited to join them. The Stammers later bought a bungalow in the Eldorado neighborhood of Diadema, São Paulo, which they rented out to Mengele. Rolf, who had not seen his father since the ski holiday in 1956, visited him at the bungalow in 1977; he found an "unrepentant Nazi" who claimed he had never personally harmed anyone and only carried out his duties as an officer.

Mengele's health had been steadily deteriorating since 1972. He suffered a stroke in 1976, experienced high blood pressure, and developed an ear infection which affected his balance. On 7 February 1979, while visiting his friends Wolfram and Liselotte Bossert in the coastal resort of Bertioga, Mengele had a stroke while swimming and drowned. His body was buried in Our Lady of the Rosary cemetery in Embu das Artes under the name "Wolfgang Gerhard", whose identification Mengele had been using since 1971. Other aliases used by Mengele in his later life included "Dr. Fausto Rindón" and "S. Josi Alvers Aspiazu".

Exhumation

Forensic anthropologists examine Mengele's skull in 1986. The skeleton is stored at the São Paulo Institute for Forensic Medicine in Brazil.

Sightings of Mengele were being reported all over the world in the decades following the war. Wiesenthal claimed to have information that placed Mengele on the Greek island of Kythnos in 1960, in Cairo in 1961, in Spain in 1971, and in Paraguay in 1978, eighteen years after he had left the country. He insisted as late as 1985 that Mengele was still alive—six years after he had died—having previously offered a reward of US$100,000 (equivalent to $300,000 in 2024) in 1982 for the fugitive's capture. Worldwide interest in the case was heightened by a mock trial held in Jerusalem in February 1985, featuring the testimonies of over one hundred victims of Mengele's experiments. Shortly afterwards, the West German, Israeli, and U.S. governments launched a coordinated effort to determine Mengele's whereabouts. The West German and Israeli governments offered rewards for his capture, as did The Washington Times and the Simon Wiesenthal Center.

On 31 May 1985, acting on intelligence received by the West German prosecutor's office, police raided the house of Hans Sedlmeier, a lifelong friend of Mengele and sales manager of the family firm in Günzburg. They found a coded address book and copies of letters sent to and received from Mengele. Among the papers was a letter from Wolfram Bossert notifying Sedlmeier of Mengele's death. German authorities alerted the police in São Paulo, who then contacted the Bosserts. Under interrogation, they revealed the location of Mengele's grave and the remains were exhumed on 6 June 1985. Extensive forensic examination indicated with a high degree of probability that the body was indeed that of Josef Mengele. Rolf Mengele issued a statement on 10 June confirming that the body was his father's and that news of his father's death had been concealed to protect people who had sheltered him.

In 1992, DNA testing confirmed Mengele's identity beyond doubt, but family members refused repeated requests by Brazilian officials to repatriate the remains to Germany. The skeleton is stored at the São Paulo Institute for Forensic Medicine, where it is used as an educational aid during forensic medicine courses at the University of São Paulo's medical school.

Later developments

In 2007, the United States Holocaust Memorial Museum received as a donation the Höcker Album, an album of photographs of Auschwitz staff taken by Karl-Friedrich Höcker. Eight of the photographs include Mengele. In February 2010, a 180-page volume of Mengele's diary was sold by Alexander Autographs at auction for an undisclosed sum to the grandson of a Holocaust survivor. The unidentified previous owner, who acquired the journals in Brazil, was reported to be close to the Mengele family. A Holocaust survivors' organization described the sale as "a cynical act of exploitation aimed at profiting from the writings of one of the most heinous Nazi criminals". Rabbi Marvin Hier of the Simon Wiesenthal Center was glad to see the diary fall into Jewish hands, calling the acquisition significant. In 2011 (centenary of Mengele's birth), a further 31 volumes of Mengele's diaries were sold—again amidst protests—by the same auction house to an undisclosed collector of World War II memorabilia for US$245,000.

Publications

• Rassenmorphologische Untersuchung des vorderen Unterkieferabschnittes bei vier rassischen Gruppen ("Racial morphological study of the anterior segment of the mandible in four racial groups"). This dissertation, completed in 1935 and first published in 1937, earned him a PhD in anthropology from Munich University. In this work Mengele sought to demonstrate that there were structural differences in the lower jaws of individuals from different ethnic groups, and that racial distinctions could be made based on these differences.
• Genealogical Studies in the Cases of Cleft Lip-Jaw-Palate (1938), his medical dissertation, earned him a doctorate in medicine from Frankfurt University. Studying the influence of genetics as a factor in the occurrence of this deformity, Mengele conducted research on families who exhibited these traits in multiple generations. The work also included notes on other abnormalities found in these family lines.
• Hereditary Transmission of Fistulae Auris. This journal article, published in Der Erbarzt ('The Genetic Physician'), focuses on fistula auris (an abnormal fissure on the external ear) as a hereditary trait. Mengele noted that individuals who have this trait also tend to have a dimple on their chin.
