Mengele was born on 16 March 1911 to Walburga (née Hupfauer) and Karl Mengele in Günzburg, Bavaria, Germany.[4] He was the oldest of three children; his two younger brothers were Karl Jr. and Alois. Their father was founder of the Karl Mengele & Sons company, producers of farm machinery.[5] Josef was successful at school and developed an interest in music, art, and skiing.[6] He completed high school in April 1930 and went on to study philosophy in Munich,[7] where the headquarters of the Nazi Party were located.[8] In 1931, Mengele joined the Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung (Storm Detachment; SA) in 1934.[7][9]
The impact of the Holocaust varied from region to region and from year to year in the 21 countries that were directly affected. Nowhere was the Holocaust more intense and sudden than in Hungary. What took place over several years in Germany occurred over 16 weeks in Hungary. Entering the war as a German ally, Hungary had persecuted its Jews but not permitted the deportation of Hungarian citizens. In 1941 foreign Jewish refugees were deported from Hungary and were shot by Germans in Kam’yanets-Podilskyy, Ukraine. After Germany invaded Hungary on March 19, 1944, the situation changed dramatically. By mid-April the Nazis had confined Jews to ghettos. On May 15, deportations began, and over the next 55 days the Nazis deported more than 437,000 Jews from Hungary to Auschwitz on 147 trains.
But there is a note that drills deeper than commemoration: it goes to the idea of identification. To “identify with” is to become what one is not, to become what one is not is to usurp, to usurp is to own—and who, after all, in the half century since Miep Gies retrieved the scattered pages of the diary, really owns Anne Frank? Who can speak for her? Her father, who, after reading the diary and confessing that he “did not know” her, went on to tell us what he thought she meant? Meyer Levin, who claimed to be her authentic voice—so much so that he dared to equate the dismissal of his work, however ignobly motivated, with Holocaust annihilation? Hellman, Bloomgarden, Kanin, whose interpretations clung to a collective ideology of human interchangeability? (In discounting the significance of the Jewish element, Kanin had asserted that “people have suffered because of being English, French, German, Italian, Ethiopian, Mohammedan, Negro, and so on”—as if this were not all the more reason to comprehend and particularize each history.) And what of Cara Wilson and “the children of the world,” who have reduced the persecution of a people to the trials of adolescence?

Following the invasion of the Soviet Union in June 1941, Einsatzgruppen and, later, militarized battalions of Order Police officials, moved behind German lines to carry out mass-murder operations against Jews, Roma, and Soviet state and Communist Party officials. German SS and police units, supported by units of the Wehrmacht and the Waffen SS, murdered more than a million Jewish men, women, and children, and hundreds of thousands of others.
Antisemitism, the new racist version of the old Jew-hatred, viewed the Jews as not simply a religious group but as members of a 'Semitic race', which strove to dominate its 'Aryan' rivals. Among the leading ideologues of this theory were a French aristocrat, the Comte Joseph de Gobineau, and an Englishman, Houston Stewart Chamberlain. Antisemitism proved a convenient glue for conspiracy theories - since Jews were involved in all sorts of ventures and political movements, they could be accused of manipulating all of them behind the scenes. Thus Jews were held responsible for Communism and capitalism, liberalism, socialism, moral decline, revolutions, wars, plagues and economic crises. As the Jews had once been demonised in medieval Europe, so the new antisemites (including many Christians) found new, secular ways of demonising them.
Life in the camps was a living hell. As described by Judah Pilch in “Years of the Holocaust: The Factual Story,” which appears in The Jewish Catastrophe in Europe, a typical day in the life of a concentration camp inmate began at dawn, when they were roused from their barracks which housed 300-800 inmates each. Their “beds” were bunks of slatted wood two and three tiers high. Frequently three to four prisoners shared each bunk, not permitting space enough for them to stretch out for normal sleep. The inmates were organized into groups to go to the toilets, marched to a distribution center for a breakfast consisting of some bread and a liquid substitute for tea or coffee, and then sent out to work for 10-14 hours in mines, factories, and road or airfield building, often in sub-zero weather or the severe heat of summer. They were subjected to constant physical and emotional harassment and beating. The inmates’ food rations did not permit survival for very long. Those who resisted orders of the guards were shot on the spot. Numerous roll calls were held to assure that no prisoners had escaped. If one did attempt an escape, all of the inmates suffered for it.
Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement.[225] Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally.[226] According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom.[227] The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police.[228] Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem".[229] In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".[230]
A person who is recognized as Righteous for having taken risks to help Jews during the Holocaust is awarded a medal in their name, a certificate of honor, and the privilege of having the name added to those on the Wall of Honor in the Garden of the Righteous at Yad Vashem in Jerusalem (the last is in lieu of a tree planting, which was discontinued for lack of space). The awards are distributed to the rescuers or their next-of-kin during ceremonies in Israel, or in their countries of residence through the offices of Israel's diplomatic representatives. These ceremonies are attended by local government representatives and are given wide media coverage.
Upon arrival at a camp in mates were stripped of their clothes and shaved of all their body hair. Then they were given a shower, disinfected and given a uniform. each step was used to dehumanize prisoners, both physically and emotionally. Prisoners were then given a number. At Auschwitz the number was tattooed on their arm. Those who the Nazis thought were unable to work were token to what they called showers. The Nazis said to these prisoners who were about to meet their deaths it was to freshen up a bit after their long journey. Instead of water Zyklon B, developed to kill rodents, closed in on them. Death Did not usually come quickly but rather slowly. Most of the walls of the death chambers had scratch marks to show how victims tried to dig themselves out. The purpose of these cams were to kill huge amounts of Jews a day. Camps had been in Germany for years. These were the places  were tons of Jews had been murdered. Once at the camps selected people would work the others were gassed. Before being gassed they forced to march to the sound of music. An important camp was Treblinka. It was established for slave labor In 1941, but in 1942 it became a death camp. By may 1943 the population of Warsaw had been transported to Treblinka and other camps. By July 11, 1944 800,000 Jews had been murdered in Treblinkia. Unlike Treblinkia, Chelmno, Sobibor, and Balzac which were made to kill Jews. Maidanek and Auschwitz had a work camp attached. Upon arrival at these two camps a selection was made. 10% of the new arrivals would escape immediate gassing.   
On 6 January 1942, the Soviet Minister of Foreign Affairs, Vyacheslav Molotov, sent out diplomatic notes about German atrocities. The notes were based on reports about bodies surfacing from poorly covered graves in pits and quarries, as well as mass graves found in areas the Red Army had liberated, and on witness reports from German-occupied areas.[335] The following month, Szlama Ber Winer escaped from the Chełmno concentration camp in Poland, and passed detailed information about it to the Oneg Shabbat group in the Warsaw Ghetto. His report, known by his pseudonym as the Grojanowski Report, had reached London by June 1942.[288][336] Also in 1942, Jan Karski sent information to the Allies after being smuggled into the Warsaw Ghetto twice.[337][s] On 27 April 1942, Vyacheslav Molotov sent out another note about atrocities.[335] In late July or early August 1942, Polish leaders learned about the mass killings taking place inside Auschwitz. The Polish Interior Ministry prepared a report, Sprawozdanie 6/42,[340] which said at the end:
In April 1944, two Jewish inmates escaped from Auschwitz and made it safely into Czechoslovakia. One of them, Rudolf Vrba, submitted a detailed report to the Papal Nuncio in Slovakia which was then forwarded to the Vatican, received there in mid-June. Thus far, Pope Pius XII had not issued a public condemnation of Nazi maltreatment and subsequent mass murder of Jews, and he chose to continue his silence.
Britain's attitude to Jewish refugees from Nazi-controlled areas was strongly influenced by its role as the mandatory power in Palestine, where it had to mediate between Jewish and Arab interests. In December 1941, the Struma, a ship carrying 769 Jewish refugees, left the Romanian port of Constantsa hoping to reach Palestine. Towed into Istanbul harbour when its engines failed, it became the subject of diplomatic discussions between Britain and Turkey. Britain's chief concern was to discourage what it regarded as an undesirable traffic, and it proposed that the ship be returned to Romania. After ten weeks of wrangling the Struma was towed out to sea, its engines still disabled, where it was sunk by a Soviet submarine. There was one survivor.

The ghettos, and the slow death they brought, were only part of the overall plan. In the months following the Wannsee Conference, three specialized killing centers, Belzec, Treblinka and Sobibor, were constructed in southeast Poland, featuring large gas chambers with adjacent crematories or burial pits for the disposal of corpses. After they became operational, the ghettos were bypassed and Jews went directly by train to the new death camps.

This was more than an exaggerated adolescent flourish. She had already intuited what greatness in literature might mean, and she clearly sensed the force of what lay under her hand in the pages of her diary: a conscious literary record of frightened lives in daily peril; an explosive document aimed directly at the future. In her last months, she was assiduously polishing phrases and editing passages with an eye to postwar publication. Het Achterhuis, as she called her manuscript, in Dutch—“the house behind,” often translated as “the secret annex”—was hardly intended to be Anne Frank’s last word; it was conceived as the forerunner work of a professional woman of letters.
The diary is not written in the classic forms of "Dear Diary" or as letters to oneself; Anne calls her diary "Kitty", so almost all of the letters are written to Kitty. Anne used the above-mentioned names for her annex-mates in the first volume, from September 25, 1942 until November 13, 1942, when the first notebook ends.[18] It is believed that these names were taken from characters found in a series of popular Dutch books written by Cissy van Marxveldt.[18]

Of the 430,000 sent to the first death camp at Bełżec in Poland, there were only two survivors. 700,000 were killed at Treblinka in just five months. In July, Himmler ordered that all Jews in key areas of Poland, except for those needed for essential labour, were to be killed by the end of the year. Most were. Despite Allied intelligence receiving detailed reports of the mass murders in Europe, the public reaction in Britain was largely a mixture of apathy and disbelief.
After its defeat in World War I, Germany was humiliated by the Versailles Treaty, which reduced its prewar territory, drastically reduced its armed forces, demanded the recognition of its guilt for the war, and stipulated it pay reparations to the allied powers. With the German Empire destroyed, a new parliamentary government called the Weimar Republic was formed. The republic suffered from economic instability, which grew worse during the worldwide depression after the New York stock market crash in 1929. Massive inflation followed by very high unemployment heightened existing class and political differences and began to undermine the government.
The Nazis then combined their racial theories with the evolutionary theories of Charles Darwin to justify their treatment of the Jews. The Germans, as the strongest and fittest, were destined to rule, while the weak and racially adulterated Jews were doomed to extinction. Hitler began to restrict the Jews with legislation and terror, which entailed burning books written by Jews, removing Jews from their professions and public schools, confiscating their businesses and property and excluding them from public events. The most infamous of the anti-Jewish legislation were the Nuremberg Laws, enacted on September 15, 1935. They formed the legal basis for the Jews' exclusion from German society and the progressively restrictive Jewish policies of the Germans.
While the Righteous Among the Nations went to different lengths to save Jews, Yad Vashem outlines four distinct ways these individuals helped the Jewish community. The first was by hiding Jews in the rescuer's home or on their property and providing food and other necessities to the Jews while in hiding. Secondly, some of the Righteous obtained false papers and false identities for those they saved. The third type of rescuer specified by Yad Vashem were those who helped Jews escape from Nazi occupied territory or to a less dangerous area. Finally, some rescuers saved children after their parents had been taken to concentration camps or killed.
The survey of her manuscripts compared an unabridged transcription of Anne Frank's original notebooks with the entries she expanded and clarified on loose paper in a rewritten form and the final edit as it was prepared for the English translation. The investigation revealed that all of the entries in the published version were accurate transcriptions of manuscript entries in Anne Frank's handwriting, and that they represented approximately a third of the material collected for the initial publication. The magnitude of edits to the text is comparable to other historical diaries such as those of Katherine Mansfield, Anaïs Nin and Leo Tolstoy in that the authors revised their diaries after the initial draft, and the material was posthumously edited into a publishable manuscript by their respective executors, only to be superseded in later decades by unexpurgated editions prepared by scholars.[57]
At the three Reinhard camps the victims were killed by the exhaust fumes of stationary diesel engines.[279] Gold fillings were pulled from the corpses before burial, but the women's hair was cut before death. At Treblinka, to calm the victims, the arrival platform was made to look like a train station, complete with fake clock.[300] Majdanek used Zyklon-B gas in its gas chambers.[301] In contrast to Auschwitz, the three Reinhard camps were quite small.[302] Most of the victims at these camps were buried in pits at first. Sobibór and Bełżec began exhuming and burning bodies in late 1942, to hide the evidence, as did Treblinka in March 1943. The bodies were burned in open fireplaces and the remaining bones crushed into powder.[303]
First, I want to say that I absolutely believe that this book should still be included in school curriculum. The only thing 'new' about it is that pages and passages were added. Nothing was taken out and the translation was not changed. Reports that the book is so different that it's nothing like the original are false. Reports that the story is different are false.
Germany invaded Norway and Denmark on 9 April 1940, during Operation Weserübung. Denmark was overrun so quickly that there was no time for an organized resistance to form. Consequently, the Danish government stayed in power and the Germans found it easier to work through it. Because of this, few measures were taken against the Danish Jews before 1942.[157] By June 1940 Norway was completely occupied.[158] In late 1940, the country's 1,800 Jews were banned from certain occupations, and in 1941 all Jews had to register their property with the government.[159] On 26 November 1942, 532 Jews were taken by police officers, at four o'clock in the morning, to Oslo harbour, where they boarded a German ship. From Germany they were sent by freight train to Auschwitz. According to Dan Stone, only nine survived the war.[160]

Mengele became interested in using twins for medical research through his mentor, Verschuer. Verschuer himself was famous for experimenting with identical and fraternal twins in order to trace the genetic origins of various diseases. During the 1930s, twin research was seen as an ideal tool in weighing the factors of human heredity and environment. Mengele and his mentor had performed a number of legitimate research protocols using twins as test subjects throughout the 1930s. Now, at Auschwitz, with full license to maim or kill his subjects, Mengele performed a broad range of agonizing and often lethal experiments with Jewish and Roma (Gypsy) twins, most of them children.
In his 1983 book, Popular Opinion and Political Dissent in the Third Reich, Ian Kershaw examined the Alltagsgeschichte (history of everyday life) in Bavaria during the Nazi period. The most common viewpoint of Bavarians was indifference towards what was happening to the Jews, he wrote. Most Bavarians were vaguely aware of the genocide, but they were vastly more concerned about the war.[472] Kershaw argued that "the road to Auschwitz was built by hate, but paved with indifference".[473] His assessment faced criticism from historians Otto Dov Kulka and Michael Kater. Kater maintained that Kershaw had downplayed the extent of popular antisemitism. Although most of the "spontaneous" antisemitic actions of Nazi Germany had been staged, Kater argued that these had involved substantial numbers of Germans, and therefore it was wrong to view the extreme antisemitism of the Nazis as coming solely from above.[474] Kulka argued that "passive complicity" would be a better term than "indifference".[475] Focusing on the views of Germans opposed to the Nazi regime, the German historian Christof Dipper, in his essay "Der Deutsche Widerstand und die Juden" (1983), argued that the majority of the anti-Nazi national-conservatives were antisemitic. No one in the German resistance supported the Holocaust, but Dipper wrote that the national conservatives did not intend to restore civil rights to the Jews after the planned overthrow of Hitler.[474]
With the invasion of the Soviet Union on June 22 1941, the Nazis launched a crusade against 'Judaeo-Bolshevism', the supposed Jewish-Communist conspiracy. Behind the front lines, four police battalions called Einsatzgruppen (operations groups) moved from town to town in the newly occupied Soviet territories, rounding up Jewish men and suspected Soviet collaborators and shooting them. In subsequent sweeps, making heavy use of local volunteers, the Einsatzgruppen targeted Jewish women and children as well. In total, the Einsaztgruppen murdered some two million people, almost all Jews.
Usage Note: Holocaust has a secure place in the language when it refers to the massive destruction of humans by other humans. In our 1987 survey 99 percent of the Usage Panel accepted the use of holocaust in the phrase nuclear holocaust. Sixty percent accepted the sentence As many as two million people may have died in the holocaust that followed the Khmer Rouge takeover in Cambodia. But because of its associations with genocide, people may object to extended applications of holocaust. The percentage of the Panel's acceptance drops sharply when people use the word to refer to death brought about by natural causes. In our 1999 survey 47 percent approved the sentence In East Africa five years of drought have brought about a holocaust in which millions have died. Just 16 percent approved The press gives little coverage to the holocaust of malaria that goes on, year after year, in tropical countries, where there is no mention of widespread mortality. The Panel has little enthusiasm for more figurative usages of holocaust. In 1999, only 7 percent accepted Numerous small investors lost their stakes in the holocaust that followed the precipitous drop in stocks. This suggests that these extended uses of the word may be viewed as overblown or in poor taste.
In 1944, Josiah DuBois, Jr. wrote a memorandum to then-Secretary of the Treasury Henry Morgenthau, Jr. entitled “Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews”, which condemned the bureaucratic interference of U.S. State Department policies in obstructing the evacuation of Holocaust Refugees from Romania and Occupied France. The Report would spur the Roosevelt administration to create the War Refugee Board later that year.

Nolte's views were widely denounced. The debate between the "specifists" and "universalists" was acrimonious; the former feared debasement of the Holocaust and the latter considered it immoral to hold the Holocaust as beyond compare.[478] In her book Denying the Holocaust (1993), Deborah Lipstadt viewed Nolte's position as a form of Holocaust denial, or at least "the same triumph of ideology over truth".[479] Addressing Nolte's argument, Eberhard Jäckel wrote in Die Zeit in September 1986 that "never before had a state, with the authority of its leader, decided and announced that a specific group of humans, including the elderly, women, children and infants, would be killed as quickly as possible, then carried out this resolution using every possible means of state power".[h] Despite the criticism of Nolte, Dan Stone wrote in 2010 that the Historikerstreit put "the question of comparison" on the agenda.[480] He argued that the idea of the Holocaust as unique has been overtaken by attempts to place it within the context of early-20th-century Stalinism, ethnic cleansing, and the Nazis' intentions for post-war "demographic reordering", particularly the Generalplan Ost, the plan to kill tens of millions of Slavs to create living space for Germans.[481] The specifist position continued nevertheless to inform the views of many specialists. Richard J. Evans argued in 2015:

Hitler quickly moved to cement his power by suspending many civil liberties and allowing imprisonment without trial. By March, the first Nazi concentration camp was established at Dachau, not to imprison Jews but to hold political dissidents. Further laws targeted Jews, restricting the jobs they could hold and revoking their German citizenship. Anti-Semitic sentiment increased as the Jewish population was blamed for many of Germany's recent and historical problems.

The rioting was triggered by the assassination of Ernst vom Rath, a German diplomat in Paris, by a Polish Jewish teenager, Herschel Grynszpan, on November 7th. Grynszpan did not attempt to escape and claimed that the assassination was motivated by the persecution of the Jewish people. Despite being attended to by Hitler’s personal physician, vom Rath died two days later.
Dr. Josef Mengele, nicknamed The Angel Of Death, and the other Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.
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".[118] Rabbi Marvin Hier of the Simon Wiesenthal Center was glad to see the diary fall into Jewish hands. "At a time when Ahmadinejad's Iran regularly denies the Holocaust and anti-Semitism and hatred of Jews is back in vogue, this acquisition is especially significant", he said.[119] In 2011, 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 $245,000 USD.[120]
