In 1992, DNA testing confirmed Mengele's identity beyond doubt,[114] but family members refused repeated requests by Brazilian officials to repatriate the remains to Germany.[115] 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.[116]
One of the clearest examples of Hitler’s single-minded (and seemingly suicidal) desire to rid the world of the Jews can be seen in the extermination of the Jews of Hungary. Until March of 1944, the Hungarian government had refused to allow the deportation of Hungarian Jews. It March 1944 the Germans occupied Hungary and by mid May ( two weeks before D Day) the mass deportations to Auschwitz. The Nazi leadership worked with particular intensity. The Soviet army was rapidly approaching Hungary and the Germans knew that they were going to lose the war. But there was no way that Hitler could allow such a large Jewish community to survive. He diverted trains that were badly needed to transport more soldiers to the Russian front just to send more Jews to Auschwitz. To him, the greater enemy was the Jew.
In 1947, the seemingly everyday, innocent thoughts of a teen girl were published. But they weren’t so everyday: they were the thoughts of Anne Frank, a 13-year-old in a unique position to make the world understand what it was like to have to hide your entire existence in exchange for a mere chance at surviving the Nazi regime. Her diary has since sold more than 30 million copies and has been translated into 67 languages. If you haven’t read The Diary of a Young Girl in a while (or even if you have), here are 10 things you should know.
In Auschwitz, the murdering of prisoners in gas chambers began even earlier, when 575 sick and disabled prisoners were sent to their deaths at the euthanasia center in Germany at the end of June 1941. At the beginning of September, the SS used Zyklon B gas in the cellars of block 11 to kill about 600 Soviet POWs and another group of patients from the camp hospital. Soviet POWs and Jews brought from Upper Silesia were killed in the gas chamber in crematorium I over the following months. It was probably at the end of March or in April 1942 that the Germans began killing sick prisoners and Jews in a provisional gas chamber in Birkenau (the so-called “little red house”). The tempo of atrocities increased in June and July 1942, with transports of Jews sent to Auschwitz being subjected to systematic “selections” during which SS doctors sentenced people classified as unfit for labor to death.
Polish gentiles who rescued Jews had several obstacles to overcome. The most serious were the German laws against protecting Jews and the corresponding obligation to identify those who violated these laws. On 15 October 1941, the Nazis introduced a widely publicized law making unauthorized Jewish movement outside ghettos a crime punishable by death. The same punishment applied to gentiles who helped Jews escape. Transgressions were promptly followed by executions that were also widely publicized.
As the mass shootings continued in Russia, the Germans began to search for new methods of mass murder. This was driven by a need to have a more efficient method than simply shooting millions of victims. Himmler also feared that the mass shootings were causing psychological problems in the SS. His concerns were shared by his subordinates in the field.[251] In December 1939 and January 1940, another method besides shooting was tried. Experimental gas vans equipped with gas cylinders and a sealed compartment were used to kill the disabled and mentally-ill in occupied Poland.[252] Similar vans, but using the exhaust fumes rather than bottled gas, were introduced to the Chełmno extermination camp in December 1941,[253] and some were used in the occupied Soviet Union, for example in smaller clearing actions in the Minsk ghetto.[254] They also were used for murder in Yugoslavia.[255]

The murder industry began in the Chelmno camp, built in December 1941. Work was carried out in special trucks, where the victims were asphyxiated by exhaust fumes, a method that had been tried before on those whose lives were deemed useless (the “Euthanasia Pro­gram”). From September 1939, about 100,000 “Aryan” Germans were assassinated in this manner, in what was named “Operation T4.” Two years later, the personnel responsible for the “euthanasia” program were called upon to apply their expertise to murdering Jews. In the single camp of Chelmno, 150,000 human beings were gassed to death, most of them brought to the camp from annexed territories, the Warthegau district of western Poland and the Lodz Ghetto.

The infamous 'Gate of Death' at Auschwitz II for the incoming freight trains was built of brick and cement mortar in 1943, and the three-track rail spur was added.[100] Until mid-August, 45,000 Thessaloniki Jews were murdered in a mere six months,[99] including over 30,000 Jews from Sosnowiec (Sosnowitz) and Bendzin Ghettos.[101] The spring of 1944 marked the beginning of the last phase of the Final Solution at Birkenau. The new big ramps and sidings were constructed, and two freight elevators were installed inside Crematoria II and III for moving the bodies faster. The size of the Sonderkommando was nearly quadrupled in preparation for the Special Operation Hungary (Sonderaktion Ungarn). In May 1944, Auschwitz-Birkenau became the site of one of the two largest mass murder operations in modern history, after the Großaktion Warschau deportations of the Warsaw Ghetto inmates to Treblinka in 1942. It is estimated that until July 1944 approximately 320,000 Hungarian Jews were gassed at Birkenau in less than eight weeks.[100] The entire operation was photographed by the SS.[102] In total, between April and November 1944, Auschwitz II received over 585,000 Jews from over a dozen regions as far as Greece, Italy, and France, including 426,000 Jews from Hungary, 67,000 from Łódź, 25,000 from Theresienstadt, and the last 23,000 Jews from the General Government.[103] Auschwitz was liberated by the Red Army on 27 January 1945, when the gassing had already stopped.[104]
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.
Not long after beginning the survey of the site, Freund and his team confirmed the existence of a previously unmarked burial pit. At 80 feet across and 15 feet deep, the scientists calculated that the grave contained the cremated remains of as many as 7,000 people. The researchers also released the preliminary results of their search for the tunnel, along with a series of ERT-generated cross sections that revealed the tunnel’s depth beneath the ground’s surface (15 feet at points) and its dimensions: three feet by three feet at the very widest, not much larger than a human torso. From the entrance inside the bunker to the spot in the forest, now long grown over, where the prisoners emerged measured more than 110 feet. At last, there was definitive proof of a story known until now only in obscure testimonies made by a handful of survivors—a kind of scientific witness that transformed “history into reality,” in the words of Miri Regev, Israel’s minister of culture, who highlighted the importance of documenting physical evidence of Nazi atrocities as a bulwark against “the lies of the Holocaust deniers.”
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.   
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.

The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
After the German invasion of Czechoslovakia in 1939, the Nazis sent many thousands of Czech Jews to ghettos in Poland, Lithuania and Latvia. On 22 June 1941, the German invasion of the Soviet Union brought many more Jews within the German sphere of influence. Some Polish Jews had managed to escape into the Soviet Union during the German invasion of Poland. Now, as the German army rolled into the Soviet Union, they were again trapped.
Anne’s childhood, by contrast, fell into shadows almost immediately. She was not yet four when the German persecutions of Jews began, and from then until the anguished close of her days she lived as a refugee and a victim. In 1933, the family fled from Germany to Holland, where Frank had commercial connections, and where he established a pectin business. By 1940, the Germans had occupied the Netherlands. In Amsterdam, Jewish children, Anne among them, were thrown out of the public-school system and made to wear the yellow star. At thirteen, on November 19, 1942, already in hiding, Anne Frank could write:
Mengele sailed to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, then fled to Paraguay in 1959 and Brazil in 1960, while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal who wanted to bring him to trial. He 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 Brazilian coast, and was buried under a false name. His remains were disinterred and positively identified by forensic examination in 1985.
