Browning believes that the "Final Solution as it is now understood—the systematic attempt to murder every last Jew within the German grasp"[5] took shape during a five-week period, from 18 September to 25 October 1941. During this time: the sites of the first extermination camps were selected, different methods of killing were tested, Jewish emigration from the Third Reich was forbidden, and 11 transports departed for Łódź as a temporary holding station. During this period, Browning writes, "The vision of the Final Solution had crystallised in the minds of the Nazi leadership, and was being turned into reality."[5] This period was the peak of Nazi victories against the Soviet Army on the Eastern Front, and, according to Browning, the stunning series of German victories led to both an expectation that the war would soon be won, and the planning of the final destruction of the "Jewish-Bolshevik enemy".[114]

After several months on the run, including a trip back to the Soviet-occupied area to recover his Auschwitz records, Mengele found work near Rosenheim as a farmhand.[62] He eventually escaped from Germany on 17 April 1949,[63][64] convinced that his capture would mean a trial and death sentence. Assisted by a network of former SS members, he used the ratline to travel to Genoa, where he obtained a passport from the International Committee of the Red Cross under the alias "Helmut Gregor", and sailed to Argentina in July 1949.[65] His wife refused to accompany him, and they divorced in 1954.[66]

In 2015, the Anne Frank Fonds made an announcement, as reported in The New York Times, that the 1947 edition of the diary was co-authored by Otto Frank. According to Yves Kugelmann, a member of the board of the foundation, their expert advice was that Otto had created a new work by editing, merging, and trimming entries from the diary and notebooks and reshaping them into a "kind of collage", which had created a new copyright. Agnès Tricoire, a lawyer specializing in intellectual property rights, responded by warning the foundation to "think very carefully about the consequences". She added "If you follow their arguments, it means that they have lied for years about the fact that it was only written by Anne Frank."[53]
Because of this book, we will remember the names, the quirks -- the characters -- of the eight people who inhabited the secret annex and their brave Dutch helpers. We will be able to visualize them long after everyone who witnessed that horrific era is gone. It is because of Anne's diary that she and her family are among the few we will remember -- the ones we feel we know -- among the millions who suffered and died as she did.
In early 1942 the Nazis built killing centres at Treblinka, Sobibor, and Belzec in occupied Poland. The death camps were to be the essential instrument of the “final solution.” The Einsatzgruppen had traveled to kill their victims. With the killing centres, the process was reversed. The victims were taken by train, often in cattle cars, to their killers. The extermination camps became factories producing corpses, effectively and efficiently, at minimal physical and psychological cost to German personnel. Assisted by Ukrainian and Latvian collaborators and prisoners of war, a few Germans could kill tens of thousands of prisoners each month. At Chelmno, the first of the extermination camps, the Nazis used mobile gas vans. Elsewhere they built permanent gas chambers linked to the crematoria where bodies were burned. Carbon monoxide was the gas of choice at most camps. Zyklon-B, an especially lethal killing agent, was employed primarily at Auschwitz and later at Majdanek.
The unstoppable Allied military advance continued and on July 24, 1944, Soviet troops liberated the first camp, Majdanek in eastern Poland, where over 360,000 had died. As the Soviet Army neared Auschwitz, Himmler ordered the complete destruction of the gas chambers. Throughout Hitler's crumbling Reich, the SS now began conducting death marches of surviving concentration camp inmates away from outlying areas, including some 66,000 from Auschwitz. Most of the inmates on these marches either dropped dead from exertion or were shot by the SS when they failed to keep up with the column.
The first killing center set up in occupied Polish lands was the camp at Chełmno on the Ner; Jews brought in from the ghettos in the Wartheland were being killed there from December 1941. Three more camps, somewhat larger, were opened at Bełżec, Sobibor, and Treblinka (in what was known as “Aktion Reinhard”) somewhat later, between March and July 1942.
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]
