The German view of the Roma as hereditary criminals and "asocials" was reflected in their classification in the concentration camps, where they were usually counted among the asocials and given black triangles to wear.[420] According to Niewyk and Nicosia, at least 130,000 died out of nearly one million in German-occupied Europe.[415] The United States Holocaust Memorial Museum calculates at least 220,000.[421] Ian Hancock, who specializes in Romani history and culture, argues for between 500,000 and 1,500,000.[422] The treatment of the Roma was not consistent across German-occupied territories. Those in France and the Low Countries were subject to restrictions on movement and some confinement to collection camps, while those in Central and Eastern Europe were sent to concentration camps and murdered by soldiers and execution squads.[423] Before being sent to the camps, the Roma were herded into ghettos, including several hundred into the Warsaw Ghetto.[219] Further east, teams of Einsatzgruppen tracked down Romani encampments and murdered the inhabitants on the spot, leaving no records of the victims.[423] After the Germans occupied Hungary, 1,000 Roma were deported to Auschwitz.[424][x]

In the autumn of 1941, SS chief Heinrich Himmler assigned German General Odilo Globocnik (SS and police leader for the Lublin District) with the implementation of a plan to systematically murder the Jews of the Generalgouvernement. The code name Operation Reinhard was eventually given to this plan, named after Heydrich (who was assassinated by Czech partisans in May 1942). As part of Operation Reinhard, Nazi leaders established three killing centers in Poland—Belzec, Sobibor, and Treblinka—with the sole purpose of the mass murder of Jews.
Mengele worked as a carpenter in Buenos Aires, Argentina, while lodging in a boarding house in the suburb of Vicente López.[67] After a few weeks he moved to the house of a Nazi sympathizer in the more affluent 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 regional sales representative.[68] He moved into an apartment in central Buenos Aires in 1953, he used family funds to buy a part interest in a carpentry concern, and he then rented a house in the suburb of Olivos in 1954.[69] 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.[70]
The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II in Nuremberg, Germany, to prosecute prominent members of the political, military, and economic leadership of Nazi Germany. The first of these trials was the 1945–1946 trial of the major war criminals before the International Military Tribunal (IMT).[456] This tribunal tried 22 political and military leaders of the Third Reich,[457] except for Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before.[456]
According to U.S. Holocaust Memorial Museum full statistics for the tragic fate of children who died during the Holocaust will never be known. Some estimates range as high as 1.5 million murdered children. This figure includes more than 1.2 million Jewish children, tens of thousands of Gypsy children and thousands of institutionalized handicapped children who were murdered under Nazi rule in Germany and occupied Europe.

Mengele's health had been steadily deteriorating since 1972. He suffered a stroke in 1976,[99] and he also had high blood pressure and an ear infection that affected his balance. On 7 February 1979, while visiting his friends Wolfram and Liselotte Bossert in the coastal resort of Bertioga, he suffered another stroke while swimming and drowned.[100] Mengele was buried in Embu das Artes under the name "Wolfgang Gerhard", whose identification he had been using since 1971.[101]
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]
Hitler also believed the very presence of Jews in Germany and Nazi-occupied Europe posed a threat to German victory in the war. This was based on his experience during the First World War, when Germany had experienced a meltdown of civilian morale. In 1916, as a young soldier on sick leave in Munich, Hitler had been appalled at the apathy and anti-war sentiment he witnessed among German civilians. At the time, he concluded disloyal Jews had banded together and conspired to undermine the German war effort. And he was convinced they would do it again now if given the chance.
In the aftermath of the Holocaust, many of the survivors found shelter in displaced persons  camps administered by the Allied powers. Between 1948 and 1951, almost 700,000 Jews emigrated to Israel, including 136,000 Jewish displaced persons from Europe. Other Jewish displaced persons emigrated to the United States and other nations. The last camp for Jewish displaced persons closed in 1957.
Josef Mengele had hoped to use the “research” he had garnered in Auschwitz in order to produce his Habilitation, a second, post-doctoral, dissertation required for admission to a university faculty as a professor in German-speaking lands. Instead, in January 1945, as the Soviet Army advanced through western Poland, Mengele fled Auschwitz. He spent the next few weeks at the Gross-Rosen concentration camp, until its evacuation. He then made his way west to evade capture by Soviet forces.
In response to this new “resettlement” policy, the first death camps were designed. Chelmno was the site of the first gassing of Jews, which occurred on December 8, 1941. The Nazi war machine had limited resources, including slave labor, much of it Jewish. Even so, the Nazis made a decision that the annihilation of the Jews of Europe was a more important achievement than the value of their labor. Similarly, the Nazis made a decision not to let the need for transport for the war effort interfere with the need for trucks and rail cars to carry the Jews to concentration camps and death centers. It was Adolf Eichmann who masterminded the logistics of the deportation of Jews. (1)
The main event of the upcoming holiday of Purim is the reading of the Megillah, which tells the story of how brave Esther and pious Mordecai saved Persian Jewry from the genocidal schemes of the wicked Haman. In the Ashkenazi tradition, the public reading of the scroll is followed by reciting a poem whose unknown author lived no later than the 11th century. The concluding lines are usually sung to an up-beat tune:
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.
On March 28, 1944, a radio broadcast from the Dutch government-in-exile in London urged the Dutch people to keep diaries, letters, and other items that would document life under German occupation. Prompted by this announcement, Anne began to edit her diary, hoping to publish it after the war under the title "The Secret Annex." From May 20 until her arrest on August 4, 1944, she transferred nearly two-thirds of her diary from her original notebooks to loose pages, making various revisions in the process.
On July 5, 1942, Anne's older sister Margot received an official summons to report to a Nazi work camp in Germany, and on July 6, Margot and Anne went into hiding with their father Otto and mother Edith. They were joined by Hermann van Pels, Otto's business partner, including his wife Auguste and their teenage son Peter.[12] Their hiding place was in the sealed-off upper rooms of the annex at the back of Otto's company building in Amsterdam.[12][13] Otto Frank started his business, named Opekta, in 1933. He was licensed to manufacture and sell pectin, a substance used to make jam. He stopped running his business while everybody was in hiding. But once he returned, he found his employees running it. The rooms that everyone hid in were concealed behind a movable bookcase in the same building as Opekta. Mrs. van Pels's dentist, Fritz Pfeffer, joined them four months later. In the published version, names were changed: The van Pelses are known as the Van Daans, and Fritz Pfeffer as Albert Dussel. With the assistance of a group of Otto Frank's trusted colleagues, they remained hidden for two years and one month.

Mengele then moved to experimentation. His work revolved around genetic engineering to eradicate inferior genes from the human population to create a German super-race. He believed that twins held these mysteries, and about 1500 pairs of them were brought to Mengele through the selection process. The twins were provided more comfort than the other prisoners and given extra food rations to keep them healthy. As soon as a pair of twins arrived at Auschwitz, they were tattooed and Mengele would ask them questions about their history. Every morning, they reported for roll call, where they ate a small breakfast. Mengele would then come to talk to them, give them candy, and even play games with some of them. Some of the younger children even called him “Uncle Mengele.” Life wasn’t so bad for twins at the barracks, until it came time for the experiments.
Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS; protection squadron) in 1938. He received basic training in 1938 with the Gebirgsjäger (light infantry mountain troop) 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-Rasse- und Siedlungshauptamt (SS Race and Settlement Main Office) in Poznań, evaluating candidates for Germanization.[18][19]
