Dr. Mengele was known by all the prisoners because of his good looks and charm. According to Gerald L. Posner and John Ware, the authors of "Mengele, the Complete Story," many of the children in the Birkenau camp "adored Mengele" and called him "Uncle Pepi." This information came from Vera Alexander, a survivor of Birkenau, who said that Dr. Mengele brought chocolate and the most beautiful clothes for the children, including hair ribbons for the little girls.
"This book confronts the record of Christian hatred and sin revealed in the baleful light of the Holocaust in a morally purifying way. It uncovers profound theological and ethical paradigms in the witness of Righteous Gentiles without glossing over or sentimentalizing the face of evil. Gushee's work is at once intellectually vital and spiritually restorative. Strongly recommended." ― Irving Greenberg, President, CLAL: National Jewish Center for Learning and Leadership
The deportation of Jews to the ghettos culminated in the policy of extermination the Nazis called the "Final Solution to the Jewish Question", discussed by senior Nazi officials at the Wannsee Conference in Berlin in January 1942. As German forces captured territories in the East, all anti-Jewish measures were radicalized. Under the coordination of the SS, with directions from the highest leadership of the Nazi Party, killings were committed within Germany itself, throughout occupied Europe, and across all territories controlled by the Axis powers. Paramilitary death squads called Einsatzgruppen, in cooperation with Wehrmacht police battalions and local collaborators, murdered around 1.3 million Jews in mass shootings between 1941 and 1945. By mid-1942, victims were being deported from the ghettos in sealed freight trains to extermination camps where, if they survived the journey, they were killed in gas chambers. The killing continued until the end of World War II in Europe in May 1945.
Mengele is known as the “Angel of Death,” or sometimes as the “White Angel,” for his coldly cruel demeanor on the ramp. He is associated more closely with this “selection duty” than any other medical officer at Auschwitz, although by most accounts he performed this task no more often than any of his colleagues. The association is partially explained by his postwar notoriety. The pervasive image of Mengele at the ramp in so many survivors' accounts has also to do with the fact that Mengele often appeared “off-duty” in the selection area whenever trainloads of new prisoners arrived at Auschwitz, searching for twins.
It is estimated that by 1942 Einsatzgruppen had killed more than 1 million Soviet troops. These victims were either shot or gassed. Jews were not the only ones killed. People who opposed Hitler were also murdered. 20th century techniques of mass production were applied in the Final Solution. Engineers of the Final Solution used these ways to cheaply and efficiently murder millions of Jews there were many ways the Nazis murdered people. Some ways were crematoriums, electrocution, injections, flame throwers, hand grenades, and gas chambers. Units of the S.S. that were specially trained followed German troops called the first wave. These squads made up the Einsatzgruppen. Nazis genocide was targeted towards Jews mass murder was targeted towards other Non-Aryans.      

The Chelmno killing center begins operation. The Nazis later establish five other such camps: Belzec, Sobibor, Treblinka, Auschwitz-Birkenau (part of the Auschwitz complex), and Majdanek. Victims at Chelmno are killed in gas vans (hermetically sealed trucks with engine exhaust diverted to the interior compartments). The Belzec, Sobibor, and Treblinka camps use carbon monoxide gas generated by stationary engines attached to gas chambers. Auschwitz-Birkenau, the largest of the killing centers, has four large gas chambers using Zyklon B (crystalline hydrogen cyanide) as the killing agent. The gas chambers at Majdanek use both carbon monoxide and Zyklon B. Millions of Jews are killed in the gas chambers in the killing centers as part of the "Final Solution."
Life in the ghetto was abominable, and thousands died. There was no medicine. The food ration allowed was a quarter of that available for the Germans, barely enough to allow survival. The water supply was contaminated in many ghettos. Epidemics of tuberculosis, typhoid, and lice were common. Bodies of new victims piled up in the streets faster than they could be carted away. In the Warsaw ghetto, more than 70,000 died of exposure, disease, and starvation during the first two winters. Almost all of those who survived the Warsaw ghetto were either killed when the ghetto was razed in 1943 or died in the death camps.
Timothy Snyder writes that Longerich "grants the significance of Greiser's murder of Jews by gas at Chełmno in December 1941", but also detects a significant moment of escalation in spring 1942, which includes "the construction of the large death factory at Treblinka for the destruction of the Warsaw Jews, and the addition of a gas chamber to the concentration camp at Auschwitz for the murder of the Jews of Silesia".[117] Longerich suggests that it "was only in the summer of 1942, that mass killing was finally understood as the realization of the Final Solution, rather than as an extensively violent preliminary to some later program of slave labor and deportation to the lands of a conquered USSR". For Longerich, to see mass killing as the Final Solution was an acknowledgement by the Nazi leadership that there would not be a German military victory over the USSR in the near future.[117]
The "Final Solution" The origin of the "Final Solution," the Nazi plan to exterminate the Jewish people, remains uncertain. What is clear is that the genocide of the Jews was the culmination of a decade of Nazi policy, under the rule of Adolf Hitler. The "Final Solution" was implemented in stages. After the Nazi party rise to power, state-enforced racism resulted in anti-Jewish legislation, boycotts, "Aryanization," and finally the "Night of Broken Glass" pogrom, all of which aimed to remove the Jews from German society. After the beginning of World War II, anti-Jewish policy evolved into a comprehensive plan to concentrate and eventually annihilate European Jewry.
Approximately 30 physicians served at Auschwitz while Mengele was assigned to the camp. As a required part feature of their “rounds,” medical staff performed “selections” of prisoners on the ramp. These selections determined who from among the mass of humanity arriving at Auschwitz would be retained for work and who would perish immediately in the gas chambers.

The deportations ... were the work of a much larger apparatus that had to deal with a host of constraints and requirements. The effort, as we shall see, was deemed necessary to accomplish the Final Solution on a European-wide scale.[p.273] 
On June 6, 1944, also known as D-Day, more than 150,000 Allied soldiers landed in France. In December the Germans started an unsuccessful counterattack in Belgium and northern France, known as the Battle of the Bulge. Continuing to gain momentum, the Soviets began an offensive in January 1945, liberating western Poland and then forcing Hungary to surrender.
Anne Frank poses in 1941 in this photo made available by Anne Frank House in Amsterdam, Netherlands. In August of 1944, Anne, her family and others who were hiding from the occupying German Security forces, were all captured and shipped off to a series of prisons and concentration camps. Anne died from typhus at age 15 in Bergen-Belsen concentration camp, but her posthumously published diary has made her a symbol of all Jews killed in World War II. #
But this week the Israeli courts waded into the process of selecting who to include on the list of righteous gentiles at the Yad Vashem Holocaust memorial in Jerusalem amid a campaign to add two Germans - one of them a convicted war criminal who was at the centre of a recent Hollywood film - and to strike off a Ukrainian who Jewish survivors say has no place among heroes.

The Germans required each ghetto to be run by a Judenrat, or Jewish council.[205] Councils were responsible for a ghetto's day-to-day operations, including distributing food, water, heat, medical care, and shelter. The Germans also required councils to confiscate property, organize forced labor, and, finally, facilitate deportations to extermination camps.[206] The councils' basic strategy was one of trying to minimize losses, by cooperating with German authorities, bribing officials, and petitioning for better conditions or clemency.[207]
A major tool of the Nazis' propaganda assault was the weekly Nazi newspaper Der Stürmer (The Attacker). At the bottom of the front page of each issue, in bold letters, the paper proclaimed, "The Jews are our misfortune!" Der Stürmer also regularly featured cartoons of Jews in which they were caricatured as hooked-nosed and ape­like. The influence of the newspaper was far-reaching: by 1938 about a half million copies were distributed weekly.
Same edition as the one I have read from my local library. This appears to be as fine an edition as you can get, and I have done a fair amount of research on that. This, the "definitive edition" has a lot of material that did not appear in the original one that was edited by Anne's father after the war. It also is on superior paper, with very readable type, and the photos are clearly rendered, compared to the other editions I have had in hand.

In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross 2nd Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with von Verschuer, who was now director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.[20][21][22]
