The nature and timing of the decisions that led to the Final Solution is an intensely researched and debated aspect of the Holocaust. The program evolved during the first 25 months of war leading to the attempt at "murdering every last Jew in the German grasp".[5] Most historians agree, wrote Christopher Browning, that the Final Solution cannot be attributed to a single decision made at one particular point in time.[5] "It is generally accepted the decision-making process was prolonged and incremental."[6] In 1940, following the Fall of France, Adolf Eichmann devised the Madagascar Plan to move Europe's Jewish population to the French colony, but the plan was abandoned for logistical reasons, mainly a naval blockade.[7] There were also preliminary plans to deport Jews to Palestine and Siberia.[8] In 1941, wrote Raul Hilberg, in the first phase of the mass murder of Jews, the mobile killing units began to pursue their victims across occupied eastern territories; in the second phase, stretching across all of German-occupied Europe, the Jewish victims were sent on death trains to centralized extermination camps built for the purpose of systematic implementation of the Final Solution.[9]
After the Warsaw Ghetto Uprising, the Ghetto was completely destroyed. Of the more than 56,000 Jews captured, about 7,000 were shot, and the remainder were deported to killing centers or concentration camps. This is a view of the remains of the ghetto, which the German SS dynamited to the ground. The Warsaw Ghetto only existed for a few years, and in that time, some 300,000 Polish Jews lost their lives there. #
In the view of Christian Gerlach, Hitler announced his decision to annihilate the Jews on or around 12 December 1941, probably on 12 December during a speech to the Gauleiters, part of the Nazi Party leadership.[259] This was one day after the German declaration of war against the United States, which followed the Japanese attack on Pearl Harbour on 7 December and the United States declaration of war on Japan on 8 December.[260] According to Deborah Dwork and Robert Jan van Pelt, Hitler had trusted American Jews, whom he assumed were all-powerful, to keep their government out of the war in the interests of German Jews. When America declared war, the Jews were blamed.[261] Joseph Goebbels, the Reich Minister of Propaganda, noted of Hitler's speech: "He warned the Jews that if they were to cause another world war, it would lead to their destruction. ... Now the world war has come. The destruction of the Jews must be its necessary consequence."[260][o]

In 1953, the Knesset, Israel's parliament, passed a law creating Yad Vashem as the country's Martyrs' and Heroes' Memorial Authority. Its tasks included commemorating the six million Jews killed by the Nazis and their collaborators during the Holocaust, paying tribute to those Jewish resistance fighters, and honoring those "high-minded Gentiles who risked their lives to save Jews." The title Righteous Among the Nations is taken from Jewish tradition (the literature of the Sages) that describes non-Jews who helped the Jewish people in times of need.

A German in a military uniform shoots at a Jewish woman after a mass execution in Mizocz, Ukraine. In October of 1942, the 1,700 people in the Mizocz ghetto fought with Ukrainian auxiliaries and German policemen who had intended to liquidate the population. About half the residents were able to flee or hide during the confusion before the uprising was finally put down. The captured survivors were taken to a ravine and shot.

The German occupation authorities carried out shooting operations of Jews and others they deemed to be potential enemies of permanent German rule in the east; these operations lasted until the Germans evacuated the Soviet Union in the first half of 1944. The SS and police often did not have sufficient manpower to carry out these operations, so they were assisted whenever necessary by local auxiliaries whom they recruited and by units of the German armed forces. The Germans and their collaborators killed between 1.0 and 1.5 million Jews in shooting operations or in gas vans in the occupied Soviet Union
Amir told me that Zeidel made several pilgrimages back to Ponar. And yet he was never able to locate the passageway that carried him to freedom. What Zeidel didn’t know was that three years before he died, a Lithuanian archaeologist named Vytautas Urbanavicius had quietly excavated what turned out to be the tunnel’s entrance. But after taking a few photographs and a notebook’s worth of measurements, he sealed up the hole with fresh mortar and stone without pressing any farther or prominently marking the area.
The 15 men present at Wannsee included Adolf Eichmann (head of Jewish affairs for the RSHA and the man who organized the deportation of Jews), Heinrich Müller (head of the Gestapo), and other party leaders and department heads.[256] Thirty copies of the minutes were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder.[263] Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony.[264] The conference had several purposes. Discussing plans for a "final solution to the Jewish question" ("Endlösung der Judenfrage"), and a "final solution to the Jewish question in Europe" ("Endlösung der europäischen Judenfrage"),[256] it was intended to share information and responsibility, coordinate efforts and policies ("Parallelisierung der Linienführung"), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German Mischlinge (half-Jews).[265] Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance."[256] He continued:
While the Nazis murdered other national and ethnic groups, such as a number of Soviet prisoners of war, Polish intellectuals, and gypsies, only the Jews were marked for systematic and total annihilation. Jews were singled out for "Special Treatment" (Sonderbehandlung), which meant that Jewish men, women and children were to be methodically killed with poisonous gas. In the exacting records kept at the Auschwitz death camp, the cause of death of Jews who had been gassed was indicated by "SB," the first letters of the two words that form the German term for "Special Treatment."
After this night, the German government supported dozens of laws and decrees that took away Jews property and livelihood. By the end of the year, Jews were prohibited from attending school. One billion reichsmarks of Jewish property was seized as collective punishment against the nation’s Jews for the murder of von Rath. Those able to flee the country did. In the year after Kristallnact, more than 100,000 Jews left Germany as the situation deteriorated.
As Nazi tyranny spread across Europe, the Germans and their collaborators persecuted and murdered millions of other people. Between two and three million Soviet prisoners of war were murdered or died of starvation, disease, neglect, or brutal treatment. The Germans targeted the non-Jewish Polish intelligentsia for killing, and deported millions of Polish and Soviet civilians for forced labor in Germany or in occupied Poland, where these individuals worked and often died under deplorable conditions.
Though much about his wartime activities was known, the German government had not requested his extradition, and even supplied him with documents clearing him of a criminal record. The German ambassador in Buenos Aires is quoted in the Mossad file on Mengele as saying he received orders to treat Mengele as an ordinary citizen since there was no arrest warrant for him. When, finally, a warrant was issued in 1959, Mengele caught word. He went into hiding, first in Paraguay and then in Brazil.

Mengele fled Germany to Argentina in 1948, using false documents given to him by the Red Cross. (According to the Mossad’s file, the organization was aware that it was helping a Nazi criminal escape justice.) In Buenos Aires, he lived at first under an assumed name, but later reverted to his own name. He even had a nameplate on his door: Dr. Josef Mengele.
Otto Frank’s own childhood, in Frankfurt, Germany, was wholly unclouded. A banker’s son, he lived untrammelled until the rise of the Nazi regime, when he was already forty-four. At nineteen, in order to acquire training in business, he went to New York with Nathan Straus, a fellow student and an heir to the Macy’s department-store fortune. During the First World War, Frank was an officer in the German military, and in 1925 he married Edith Holländer, a manufacturer’s daughter. Margot was born in 1926 and Anneliese Marie, called Anne, in 1929. His characteristically secular world view belonged to an era of quiet assimilation, or, more accurately, accommodation (which includes a modicum of deference), when German Jews had become, at least in their own minds, well integrated into German society. From birth, Otto Frank had breathed the free air of the affluent bourgeoisie.

On November 4, 1943, Globocnik wrote to Himmler from Trieste: "I have, on Oct. 19, 1943, completed Action Reinhard, and closed all the camps." He asked for special medals for his men in recognition of their "specially difficult task". Himmler responded warmly to 'Globos' on November 30, 1943, thanking him for carrying out Operation Reinhard. Also in: Holocaust Encyclopedia. ""Final Solution": Overview".

It is not known when Hitler formed the intention of the “final solution of the Jewish question” on the scale of the European continent. The conference in Wannsee on January 20, 1942 considered only the details of the undertaking: the methods for organizing the deportation and ensuring the cooperation of the civilian administration. Overall, the plans called for the murder of 11 million Jews living in Germany, the occupied territory, the states opposed to the Third Reich, and the allied and neutral countries. 
This past fall, I reached out to Hana Amir, Zeidel’s daughter, and we spoke several times over Skype. From her home in Tel Aviv, Amir, who is slight and spectacled, with a gray bob, told me about how she learned of her father’s story. When Amir was young, Zeidel worked as a truck driver, and he was gone for long stretches at a time. At home, he was withholding with his daughter and two sons. “My father was of a generation that didn’t talk about their emotions, didn’t talk about how they felt about what they’d been through,” Amir told me. “This was their coping mechanism: If you’re so busy with moving forward, you can disconnect from your memories.” But there were signs that the past wasn’t done with Zeidel: Amir believes he suffered from recurrent nightmares, and he was fastidious about his personal hygiene—he washed his hands many times a day.

Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]

Anne Frank escaped gassing. One month before liberation, not yet sixteen, she died of typhus fever, an acute infectious disease carried by lice. The precise date of her death has never been determined. She and her sister, Margot, were among three thousand six hundred and fifty-nine women transported by cattle car from Auschwitz to the merciless conditions of Bergen-Belsen, a barren tract of mud. In a cold, wet autumn, they suffered through nights on flooded straw in overcrowded tents, without light, surrounded by latrine ditches, until a violent hailstorm tore away what had passed for shelter. Weakened by brutality, chaos, and hunger, fifty thousand men and women—insufficiently clothed, tormented by lice—succumbed, many to the typhus epidemic.
If a front-page review in the New York Times Book Review can rocket a book to instant sanctity, that is what Meyer Levin, in the spring of 1952, achieved for “Anne Frank: The Diary of a Young Girl.” It was an assignment he had gone after avidly. Barbara Zimmerman (afterward Barbara Epstein, a founder of The New York Review of Books), the diary’s young editor at Doubleday, had earlier recognized its potential as “a minor classic,” and had enlisted Eleanor Roosevelt to supply an introduction. (According to Levin, it was ghostwritten by Zimmerman.) Levin now joined Zimmerman and Doubleday in the project of choosing a producer. Doubleday was to take over as Frank’s official agent, with the stipulation that Levin would have an active hand in the adaptation. “I think that I can honestly say,” Levin wrote Frank, “that I am as well qualified as any other writer for this particular task.” In a cable to Doubleday, Frank appeared to agree: “DESIRE LEVIN AS WRITER OR COLLABORATOR IN ANY TREATMENT TO GUARANTEE IDEA OF BOOK.” The catch, it would develop, lurked in a perilous contingency: Whose idea? Levin’s? Frank’s? The producer’s? The director’s? In any case, Doubleday was already doubtful about Levin’s ambiguous role: What if an interested producer decided on another playwright?
In early 1943, encouraged by von Verschuer, Mengele applied to transfer to the concentration camp service.[20][30] His 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 Birkenau,[20][30] a subcamp located on the main Auschwitz complex. 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.[31] 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.[32]
