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draft, and the material was posthumously edited into a publishable manuscript by their respective executors, only to be superseded in later decades by unexpurgated editions prepared by scholars.[57]

After the war, Mengele escaped internment and went underground, serving for four years as a farm stableman near Rosenheim in Bavaria. Then he reportedly escaped, via Genoa, Italy, to South America in 1949. He married (for a second time) under his own name in Uruguay in 1958 and, as “José Mengele,” received citizenship in Paraguay in 1959. In 1961 he apparently moved to Brazil, reportedly becoming friends with an old-time Nazi, Wolfgang Gerhard, and living in a succession of houses owned by a Hungarian couple. In 1985 a team of Brazilian, West German, and American forensic experts determined that Mengele had taken Gerhard’s identity, died in 1979 of a stroke while swimming, and was buried under Gerhard’s name. Dental records later confirmed the forensic conclusion.
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.
Life within Nazi concentration camps was horrible. Prisoners were forced to do hard physical labor and given little food. Prisoners slept three or more to a crowded wooden bunk; bedding was unheard of. Torture within the concentration camps was common and deaths were frequent. At a number of concentration camps, Nazi doctors conducted medical experiments on prisoners against their will.
His “obsession,” as he afterward called it—partly in mockery of the opposition his later views evoked—had its beginning in those repeated scenes of piled-up bodies as he investigated camp after camp. From then on, he could be said to carry the mark of Abel. He dedicated himself to helping the survivors get to Mandate Palestine, a goal that Britain had made illegal. In 1946, he reported from Tel Aviv on the uprising against British rule, and during the next two years he produced a pair of films on the struggles of the survivors to reach Palestine. In 1950, he published “In Search,” an examination of the effects of the European cataclysm on his experience and sensibility as an American Jew. (Thomas Mann acclaimed the book as “a human document of high order, written by a witness of our fantastic epoch whose gaze remained both clear and steady.”) Levin’s intensifying focus on the Jewish condition in the twentieth century grew more and more heated, and when his wife, the novelist Tereska Torres, handed him the French edition of the diary (it had previously appeared only in Dutch) he felt he had found what he had thirsted after: a voice crying up from the ground, an authentic witness to the German onslaught.
We were faced with the question: what about the women and children? – I have decided on a solution to this problem. I did not consider myself justified to exterminate the men only – in other words, to kill them or have them killed while allowing the avengers, in the form of their children, to grow up in the midst of our sons and grandsons. The difficult decision had to be made to have this people disappear from the earth.

The Nazi killing site at Ponar is today known to scholars as one of the first examples of the “Holocaust by bullets”—the mass shootings that claimed the lives of upwards of two million Jews across Eastern Europe. Unlike the infamous gas chambers at places like Auschwitz, these murders were carried out at close range, with rifles and machine guns. Significantly, the killings at Ponar marked the transition to the Final Solution, the Nazi policy under which Jews would no longer be imprisoned in labor camps or expelled from Europe but exterminated.
After the June 1941 German invasion of the Soviet Union, SS and police units (acting as mobile killing units) began massive killing operations aimed at entire Jewish communities. By autumn 1941, the SS and police introduced mobile gas vans. These paneled trucks had exhaust pipes reconfigured to pump poisonous carbon monoxide gas into sealed spaces, killing those locked within. They were designed to complement ongoing shooting operations.

Himmler ordered the closure of ghettos in Poland in mid-July 1942; most inhabitants were sent to extermination camps. Those Jews needed for war production would be confined in concentration camps.[220] The deportations from the Warsaw Ghetto began on 22 July; over the almost two months of the Aktion, until 12 September, the population was reduced from 350,000 to 65,000. Those deported were transported in freight trains to the Treblinka extermination camp.[221] Similar deportations happened in other ghettos, with many ghettos totally emptied.[222] The first ghetto uprisings occurred in mid-1942 in small community ghettos.[223] Although there were armed resistance attempts in both the larger and smaller ghettos in 1943, in every case they failed against the overwhelming German military force, and the remaining Jews were either killed or deported to the death camps.[224]
The Nazis brought their own strain of radical ruthlessness to these ideas. They glorified war and saw the uncompromising struggle for survival between nations and races as the engine of human progress. They rejected morality as a Jewish idea, which had corrupted and weakened the German people. They maintained that a great nation such as Germany had the right and duty to build an empire based on the subjugation of 'inferior races'. They looked eastwards to Poland and Russia (where, as it happened, the great majority of European Jews lived) for the territorial expansion of their 'living space' (Lebensraum).

Ruth Elias and her husband had conceived a child while she was a prisoner in the Theresienstadt camp, and when she arrived at Birkenau on a transport of Czech prisoners in December 1943, she was three months pregnant. Ruth passed several selections for the gas chamber even though she was obviously pregnant; she and her husband were assigned to the Czech "family camp." On July 11, 1944, after a selection made by Dr. Mengele, 3,000 prisoners in the Czech family camp, who were not considered fit to work, were sent to the gas chamber, but Ruth passed the selection even though she was in her eighth month of pregnancy. On July 14, 1944, Ruth was sent to Hamburg, Germany to work in clearing rubble from Allied bombing raids.
He inspired Anne: she planned after the war to publish a book about her time in hiding. She also came up with a title: Het Achterhuis, or The Secret Annex. She started working on this project on 20 May 1944. Anne rewrote a large part of her diary, omitted some texts and added many new ones. She wrote the new texts on separate sheets of paper. She describes the period from 12 June 1942 to 29 March 1944. Anne worked hard: in a those few months, she wrote around 50,000 words, filling more than 215 sheets of paper.
As a temporary measure, while the top leadership considered long-term options, German authorities established ghettos in the Generalgouvernement (that part of German-occupied Poland not directly annexed to Germany, attached to German East Prussia or incorporated into the German-occupied Soviet Union) and in the District Wartheland, commonly called the Warthegau (an area of western Poland directly annexed to the German Reich). From late 1939, German SS and police authorities deported Polish, German, Austrian, and Czech Jews to these ghettos.
Many healthy, young strong Jews were not killed immediately. The Germans' war effort and the “Final Solution” required a great deal of manpower, so the Germans reserved large pools of Jews for slave labor. These people, imprisoned in concentration and labor camps, were forced to work in German munitions and other factories, such as I.G. Farben and Krupps, and wherever the Nazis needed laborers. They were worked from dawn until dark without adequate food and shelter. Thousands perished, literally worked to death by the Germans and their collaborators.

After the Nuremberg war crimes trials finished, the United States spearheaded the effort to end genocide and become a champion for the prevention of crimes against humanity. The U.S. pushed for greater international effort, helping to draft the 1948 Genocide Convention. President Harry Truman addressed Congress urging the Convention’s passage. He stressed the role the United States had to play in “outlawing the world-shocking crime of genocide.”

This was upgraded on 31 July 1941, when Hermann Goering sent an order that Heydrich should make “all necessary preparations with regard to organisational, practical and financial aspects for an overall solution to the Jewish question”. Heydrich was to “submit an overall plan… for the execution of the intended ‘Final Solution’ of the Jewish question”.

What happened next—an avalanche of furies and recriminations lasting years—has lately become the subject of a pair of arresting discussions of the Frank-Levin affair. And if “affair” suggests an event on the scale of the Dreyfus case, that is how Levin saw it: as an unjust stripping away of his rightful position, with implications far beyond his personal predicament. “An Obsession with Anne Frank,” by Lawrence Graver, published by the University of California Press in 1995, is the first study to fashion a coherent narrative out of the welter of claims, counterclaims, letters, cables, petitions, polemics, and rumbling confusions which accompany any examination of the diary’s journey to the stage. “The Stolen Legacy of Anne Frank,” by Ralph Melnick, out just now from Yale, is denser in detail and in sources than its predecessor, and more insistent in tone. Both are accomplished works of scholarship that converge on the facts and diverge in their conclusions. Graver is reticent with his sympathies; Melnick is Levin’s undisguised advocate. Graver finds no villains; Melnick finds Lillian Hellman.
On January 20, 1942, several top officials of the German government met to officially coordinate the military and civilian administrative branches of the Nazi system to organize a system of mass murder of the Jews. This meeting, called the Wannsee Conference, "marked the beinning of the full-scale, comprehensive extermination operation [of the Jews] and laid the foundations for its organization, which started immediately after the conference ended" (Yahil, The Holocaust, p. 318).

The second is the saris, usually translated as “eunuch,” whose despair comes from childlessness. To him the prophet promises “a place and a name,” in Hebrew yad va-shem—a phrase, sometimes rendered “everlasting memorial,” that gives its name to Israel’s Holocaust memorial museum. Don’t worry, Isaiah is saying, you may think that your lack of progeny means that your name won’t live on. But God promises it will live on forever.
Concentration camps were top priority in the conference. ""Nazis would trap Jews in ghettos'' said Himmler. Then they were taken to death camps. Auschwitz mainly. They killed 1 to 3 million people there. '' Under proper guidance in the Final Solution the Jews are to be relocated for appropriate  labor in the east. Able-bodied Jews will be separated according to sex. Then taken in large work columns to work on roads of course many will die of natural causes.'' Himmler said this during the conference.

After the Wannsee Conference in January 1942, the Nazis began the systematic deportation of Jews from all over Europe to six extermination camps established in former Polish territory -- Chelmno , Belzec, Sobibor, Treblinka, Auschwitz-Birkenau, and Majdanek. Extermination camps were killing centers designed to carry out genocide. About three million Jews were gassed in extermination camps.
"Despite decades of Holocaust studies and even mass media attention (e.g., Shindler's List), no full-length treatment of the Righteous Gentiles has appeared in and for Christian ethics. Who were these people? Why did they do what they did? What kind of Christianity was theirs, if any? How do we assess them, from a moral point of view? And what does it all mean for Christian ethics? Finally, with this book the lacuna has been filled, and David Gushess does it so very, very well." ―Larry L. Rasmussen, Union Theological Seminary
By 1943 it was evident to the armed forces leadership that Germany was losing the war.[358] The mass murder continued nevertheless, reaching a "frenetic" pace in 1944.[359] Auschwitz was gassing up to 6,000 Jews a day by spring that year.[360] On 19 March 1944, Hitler ordered the military occupation of Hungary and dispatched Eichmann to Budapest to supervise the deportation of the country's Jews.[361] From 22 March, Jews were required to wear the yellow star; forbidden from owning cars, bicycles, radios or telephones; then forced into ghettos.[362] From 15 May to 9 July, 440,000 Jews were deported from Hungary to Auschwitz-Birkenau, almost all to the gas chambers.[v] A month before the deportations began, Eichmann offered to exchange one million Jews for 10,000 trucks and other goods from the Allies, the so-called "blood for goods" proposal.[365] The Times called it "a new level of fantasy and self-deception".[366]
Along with several other Auschwitz doctors, Mengele transferred to Gross-Rosen concentration camp in Lower Silesia on 17 January 1945, taking with him two boxes of specimens and the records of his experiments at Auschwitz. Most of the camp medical records had already been destroyed by the SS[57][58] by the time the Red Army liberated Auschwitz on 27 January.[59] Mengele fled Gross-Rosen on 18 February, a week before the Soviets arrived there, and traveled westward to Žatec in Czechoslovakia, disguised as a Wehrmacht officer. There he temporarily entrusted his incriminating documents to a nurse with whom he had struck up a relationship.[57] He and his unit then hurried west to avoid being captured by the Soviets, but were taken prisoners of war by the Americans in June 1945. Although Mengele was initially registered under his own name, he was not identified as being on the major war criminal list due to the disorganization of the Allies regarding the distribution of wanted lists, and the fact that he did not have the usual SS blood group tattoo.[60] He was released at the end of July and obtained false papers under the name "Fritz Ullman", documents he later altered to read "Fritz Hollmann".[61]
