In 1935, Mengele earned a PhD in anthropology from the University of Munich.[7] In January 1937, he joined the Institute for Hereditary Biology and Racial Hygiene in Frankfurt, where he worked for Dr. Otmar Freiherr von Verschuer, a German geneticist with a particular interest in researching twins.[7] As von Verschuer's assistant, Mengele focused on the genetic factors that result in a cleft lip and palate, or a cleft chin.[10] His thesis on the subject earned him a cum laude doctorate in medicine (MD) from the University of Frankfurt in 1938.[11] (Both of his degrees were revoked by the issuing universities in the 1960s.)[12] In a letter of recommendation, von Verschuer praised Mengele's reliability and his ability to verbally present complex material in a clear manner.[13] The American author Robert Jay Lifton notes that Mengele's published works were in keeping with the scientific mainstream of the time, and would probably have been viewed as valid scientific efforts even outside Nazi Germany.[13]
Although many people responded with obstructionism and doubt,  several rescue operations were run throughout Axis-controlled Europe. Some were the work of prominent individuals like Raoul Wallenberg and Carl Lutz who worked largely alone while other operations were far more complex. A network of Catholic bishops and clergymen organized local protests and shelter campaigns throughout much of Europe that are today estimated to have saved 860,000 lives. Danish fishermen clandestinely ferried more than 7,000 Jews into neutral Sweden while the French town of Chambon-sur-Lignon sheltered between 3,000 and 5,000 refugees.
“We had big gaps in our knowledge because most of the documentation about how the genocide was carried out on the ground was captured by the Soviet Red Army and wasn’t available until after the Cold War,” says White. The fall of the Soviet Union led to a feast of wartime bureaucratic records, allowing historians to realize how much leeway Nazi officials were given. It became readily clear that the number of Nazis involved in enacting the Final Solution was much larger than previously believed.
In May 1960, Isser Harel, director of Mossad (the Israeli intelligence agency), personally led the successful effort to capture Adolf Eichmann in Buenos Aires. He was also hoping to track down Mengele, so that he too could be brought to trial in Israel.[84] 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.[85]
Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.
Within a month of his arrival at Auschwitz, an outbreak of noma erupted in the Gypsy camp. Mengele’s solution was to send over 1000 Gypsies to the gas chamber. A similar event occurred in the women’s camp a month later, and the doctor sent more than 600 women with typhus to the same fate. In one of the most horrific exterminations, Mengele and a group of other officers circled a fire pit before about 10 dump trucks filled with children arrived. The trucks backed up to the fire and Mengele and the other officers started throwing the children into the pit. The children screamed as they were burned alive, while others managed to crawl out of the pit. But the officers walked around the pit with sticks and pushed those who managed to get out back into the fire.
Hitler’s understanding of the role of the Jews in the world was not warped. His was, in fact, the traditional Jewish understanding. When the Jews accepted the Torah at Mt. Sinai, they became the chosen people whose role and responsibility was to bring a God-given code of morality to the world. They were to be “the light unto the nations” in the words of prophet Isaiah.
In the early part of 1939, my father, mother and infant brother were living in Paris, as refugees from the pogroms in Romania. They were illegal immigrants, living modestly with the hope of giving themselves and their son a better future than the one they had. But World War II was approaching, and the citizens of France were in danger of falling prey to the Vichy regime that was collaborating with Germany and Hitler. As Jews and illegal residents, my parents were in an extremely precarious situation. They were poor and had no connections or reasonable way of changing their situation. But a gentile, the wife of an Italian diplomat for whom my mother sewed her clothes, understood what the future of my family would be if they stayed in France. In an act of righteousness, mercy and generosity, she offered my parents tickets: first for the train to Marseilles and then, passage onto a ship bound to Bolivia. I was born in Bolivia, where my family’s life was spared the horrors of the Holocaust. I have eternal gratitude to the woman who saved us.
15-year-old Anne looked very critically at the texts written by 13-year-old Anne. She gave to the texts written during the first six months in hiding an especially thorough going-over. There, the differences between the original diary and Anne's rewritten version are the greatest. Since the original diary letters from 1943 have not survived, we do not know anything about them. It is noteworthy that in The Secret Annex, Anne left out her notes about her love for Peter and her vicious remarks about her mother, such as 'my mother is in most things an example to me, but then an example of precisely how I shouldn’t do things.'
Mengele injected chemicals into the eyes of children in an attempt to change their eye color. Unfortunately a strict veil of secrecy over the experiments enabled Mengele to do his work more effectively.The full extent of his gruesome work will never be known because the records he sent to Dr. Von Verschuer at the Kaiser Wilhelm Institute were shipped out in two truckloads and destroyed by the latter.

“Awesome as they are, therefore, numbers do not in themselves prescribe the singularity of the Holocaust. But they provide a clue. For the proportion of European Jews killed during the Second World War, with roughly one of every three civilian deaths in Europe being that of a Jew, was undoubtedly greater than that of any other people, because of the Nazis’ policy toward them. Unlike the case with any other group, and unlike the massacres before or since, every single one of the millions of targeted Jews was to be murdered. Eradication was to be total. In principle, no Jew was to escape. In this important respect, the Nazis’ assault upon Jewry differed from the campaigns against other peoples and groups; Gypsies, Jehovah’s Witnesses, homosexuals, Poles, Ukrainians, and so on. Assaults on these people could indeed be murderous; their victims number in the millions, and their ashes mingle with those of the Jews of Auschwitz and many other camps across Europe. But Nazi ideology did not require their total disappearance. In this respect, the fate of the Jews was unique.”

The Holocaust did not happen a day. It grew for 2000 years un till it peaked. Weather Hitler was there or not to take advantage of the moment . Or weather he was there to cause it to peak is debatable. It happened because nobody would stop it. 'The killing stopped in 1944 the anti-Semitism did not''. Anti-Semitism led to the final solution. Which was the Nazis plan to kill all the Jews in Europe. It was carried out by killing squads ,ghettos, and camps. The Final Solution was personal but it was also a project. It was not just the actions of Hitler but a plan carried out by the world. ''Jews are not humans''. Or that's what some of the soldiers said. With a national precipitation it was easy for cruel and mean acts to be committed. Nazis rounded up Jehovah's witnesses and homo sexual and sent them to cams to be gassed. Homo Sexual were forced to wear a pink triangle periling the star of David.

Wallenberg was a Swedish diplomat who helped save thousands of Hungarian Jews. Wallenberg provided thousands of Jews with special Swedish passports and also set up a bureaucracy in Budapest designed to protect Jews by using "safe houses" where they could receive food and medical supplies. More than 90,000 Budapest Jews were deported to death camps; Wallenberg's efforts may have saved an equal number. Following the liberation of Budapest, Wallenberg was arrested by the Soviets and was never heard from again.
On November 12, 1938, Field Marshal Hermann Göring convened a meeting of Nazi officials to discuss the damage to the German economy from pogroms. The Jewish community was fined one billion Reichsmarks. Moreover, Jews were made responsible for cleaning up the damage. German Jews, but not foreign Jews, were barred from collecting insurance. In addition, Jews were soon denied entry to theatres, forced to travel in separate compartments on trains, and excluded from German schools. These new restrictions were added to earlier prohibitions, such as those barring Jews from earning university degrees, from owning businesses, or from practicing law or medicine in the service of non-Jews. The Nazis would continue to confiscate Jewish property in a program called “Aryanization.” Göring concluded the November meeting with a note of irony: “I would not like to be a Jew in Germany!”
The sins of the Soviets and the sins of Hellman and her Broadway deputies were, in Levin’s mind, identical. He set out to punish the man who had allowed all this to come to pass: Otto Frank had allied himself with the pundits of erasure; Otto Frank had stood aside when Levin’s play was elbowed out of the way. What recourse remained for a man so affronted and injured? Meyer Levin sued Otto Frank. It was as if, someone observed, a suit were being brought against the father of Joan of Arc. The bulky snarl of courtroom arguments resulted in small satisfaction for Levin: because the structure of the Hacketts’ play was in some ways similar to his, the jury detected plagiarism; yet even this limited triumph foundered on the issue of damages. Levin sent out broadsides, collected signatures, summoned a committee of advocacy, lectured from pulpits, took out ads, rallied rabbis and writers (Norman Mailer among them). He wrote “The Obsession,” his grandly confessional “J’Accuse,” rehearsing, in skirmish after skirmish, his fight for the staging of his own adaptation. In return, furious charges flew at him: he was a red-baiter, a McCarthyite. The term “paranoid” began to circulate. Why rant against the popularization and dilution that was Broadway’s lifeblood? “I certainly have no wish to inflict depression on an audience,” Kanin had argued. “I don’t consider that a legitimate theatrical end.” (So much for “Hamlet” and “King Lear.")
Mengele is known as the “Angel of Death,” or sometimes as the “White Angel,” for his coldly cruel demeanor on the ramp. He is associated more closely with this “selection duty” than any other medical officer at Auschwitz, although by most accounts he performed this task no more often than any of his colleagues. The association is partially explained by his postwar notoriety. The pervasive image of Mengele at the ramp in so many survivors' accounts has also to do with the fact that Mengele often appeared “off-duty” in the selection area whenever trainloads of new prisoners arrived at Auschwitz, searching for twins.
The manuscript, written on loose sheets of paper, was found strewn on the floor of the hiding place by Miep Gies and Bep Voskuijl after the family's arrest,[17] but before their rooms were ransacked by the Dutch police and the Gestapo. They were kept safe, and given to Otto Frank after the war, with the original notes, when Anne's death was confirmed in the spring of 1945.[citation needed]
12 million people were killed by the nazi party, But there was no trace of written order and many questions still remain unanswered. Half a million Gypsies were murdered by the Nazis. Nazis thought Jews to be as low as Jews. They were worked to death or gassed. Nazis murdered 5-6 million Jews two thirds of European Jewry one third of their population. 55 million perished in all 20 million Soviet citizens 5 million Germans and three million non-Jewish poles. 

"He grabbed my arm and turned me around," said Freund, now 82. "I was skinny, already. Thank God I didn't have a pimple on my body, because a pimple was all you needed to be sent to the crematorium." (The gas chambers at Auschwitz were located in the crematorium buildings, so that the bodies could be burned immediately after the victims were gassed.)
The foundation also relies on the fact that another editor, Mirjam Pressler, had revised the text and added 25 percent more material drawn from the diary for a "definitive edition" in 1991, and Pressler was still alive in 2015, thus creating another long-lasting new copyright.[53] The move was seen as an attempt to extend the copyright term. Attard had criticised this action only as a "question of money",[58] and Ertzscheid concurred, stating, "It [the diary] belongs to everyone. And it is up to each to measure its importance."[59]

Auschwitz, perhaps the most notorious and lethal of the concentration camps, was actually three camps in one: a prison camp (Auschwitz I), an extermination camp (Auschwitz II–Birkenau), and a slave labour camp (Auschwitz III–Buna-Monowitz). Upon arrival, Jewish prisoners faced what was called a Selektion. A German doctor presided over the selection of pregnant women, young children, the elderly, handicapped, sick, and infirm for immediate death in the gas chambers. As necessary, the Germans selected able-bodied prisoners for forced labour in the factories adjacent to Auschwitz, where one German company, IG Farben, invested 700 million Reichsmarks in 1942 alone to take advantage of forced labour, a capital investment. The conglomerate presumed that slave labour would be a permanent part of the German economy. Deprived of adequate food, shelter, clothing, and medical care, these prisoners were literally worked to death. Periodically, they would face another Selektion. The Nazis would transfer those unable to work to the gas chambers of Birkenau.
This graphic adaptation is so engaging and effective that it’s easy to imagine it replacing the “Diary” in classrooms and among younger readers. For that reason especially, it seems a mistake not to have included more in the way of critical apparatus to explain the ways the creators diverged from the historical record, especially when they touch most directly on the Holocaust. There is, for example, a naïve, stylized rendering of a concentration camp scene, which makes sense as a representation of Anne’s fantasies — she didn’t know the barbaric specifics of what was going on around her — but risks confusing students, who might not know that Auschwitz wasn’t in fact a big green square surrounded by pleasant-looking buildings with huge canisters reading “GAS” plugged into them.

In his monograph, The Origins Of The Final Solution: The Evolution of Nazi Jewish Policy, September 1939 – March 1942, Christopher Browning argues that Nazi policy toward the Jews was radicalized twice: in September 1939, when the invasion of Poland implied policies of mass expulsion and massive loss of Jewish lives; and in spring 1941, when preparation for Operation Barbarossa involved the planning of mass execution, mass expulsion, and starvation – to dwarf what had happened in Jewish Poland.[113]
“Instead of immigration there is now a further possible solution to which the Fuhrer has already signified his consent. Namely deportation to the East. Although this should be regarded merely as an interim measure, it will provide us with the practical experience which will be especially valuable in connection with the future final solution. In the course of the practical implementation of the final solution Europe will be combed from West to East.”
The forest burst orange with gunfire. “I looked around: Our entire path was filled with people crawling,” Farber has written. “Some jumped up and started running in various directions.” Farber and Dogim cut through the fence and tore off into the woods, with Zeidel and three others in tow. The men ran all night, through rivers, through forests, past villages. After a week, the escapees were deep inside the Rudnitsky Woods. Farber introduced himself to the partisan leader. “Where do you come from?” the man asked.
In September 1939, the German army occupied the western half of Poland. German police soon forced tens of thousands of Polish Jews from their homes and into ghettoes, giving their confiscated properties to ethnic Germans (non-Jews outside Germany who identified as German), Germans from the Reich or Polish gentiles. Surrounded by high walls and barbed wire, the Jewish ghettoes in Poland functioned like captive city-states, governed by Jewish Councils. In addition to widespread unemployment, poverty and hunger, overpopulation made the ghettoes breeding grounds for disease such as typhus.
In 2015, the Anne Frank Fonds made an announcement, as reported in The New York Times, that the 1947 edition of the diary was co-authored by Otto Frank. According to Yves Kugelmann, a member of the board of the foundation, their expert advice was that Otto had created a new work by editing, merging, and trimming entries from the diary and notebooks and reshaping them into a "kind of collage", which had created a new copyright. Agnès Tricoire, a lawyer specializing in intellectual property rights, responded by warning the foundation to "think very carefully about the consequences". She added "If you follow their arguments, it means that they have lied for years about the fact that it was only written by Anne Frank."[53]
While these massacres were happening, the Nazis elsewhere were laying plans for an overall 'solution to the Jewish question'. Death camp operations began in December 1941 at Semlin in Serbia and Chelmno in Poland, where people were killed by exhaust fumes in specially modified vans, which were then driven to nearby sites where the bodies were plundered and burnt. 250,000 Jews were killed this way at Chelmno and 15,000 at Semlin.

The conference at Wannsee gave impetus to the so-called second sweep of the Holocaust by the bullet in the east. Between April and July 1942 in Volhynia, 30,000 Jews were murdered in death pits with the help of dozens of newly formed Ukrainian Schutzmannschaft.[67] Owing to good relations with the Ukrainian Hilfsverwaltung,[68] these auxiliary battalions were deployed by the SS also in Russia Center, Russia South, and in Byelorussia; each with about 500 soldiers divided into three companies.[69] They participated in the extermination of 150,000 Volhynian Jews alone, or 98 percent of the Jewish inhabitants of the entire region.[70] In July 1942 the Completion of the Final Solution in the General Government territory which included Distrikt Galizien, was ordered personally by Himmler. He set the initial deadline for 31 December 1942.[71]
Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments,[33] with a particular interest in locating sets of twins.[34] 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 a tune.[35][31] He was also 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.[36]
