Browning’s account of the evolution of the Nazi genocide is the most comprehensive that has yet appeared, and it is no exaggeration to say that the author, who offers here 110 pages of endnotes, has read and absorbed every available document of relevance. Yet one must continue to wonder whether Hitler really waited until August-October 1941 to decide on a policy of genocide. Hitler habitually thought in demographic and social-Darwinist terms, and from 1939 onwards, he was confronted by a new demographic reality”that he now had many millions of Jews under his thumb, far more than the mere five hundred thousand in Nazi Germany in 1933, a figure itself ever-diminishing through emigration. With the conquest of western Poland in mid-1939, over two million Jews came under his rule, while the invasion and conquest of the Soviet Union would add another five million, entirely apart from the many Jews in Nazi satellite states such as Hungary and Romania. It is very difficult to believe that Hitler did not contemplate genocide along with the invasion of the Soviet Union, given the fact that he would soon have the ability to get rid of all of Europe’s Jews in one fell swoop. As Browning carefully notes, as early as February 1941 Hitler remarked to a number of other top Nazis that towards the Jews “he was thinking of many things in a different way, not exactly more friendly.” 

Freund and I walked the path of the tunnel, over the large hummock of earth, out toward the surrounding pines. Not such a long distance on foot, perhaps, but positively heroic when one considered that it had been dug, night after night, by chained men who had spent their daylight hours laboring at their unthinkable task, subsisting on nothing more than gruel.
Title bestowed by Yad Vashem (the Israeli Holocaust remembrance authority) on certain gentiles who rescued Jews in opposition to Nazi efforts to annihilate them. The distinction is granted according to stringent criteria requiring conclusive evidence. Depending on the nature and extent of help, special kinds of recognition are bestowed upon Christians who saved Jews. To qualify for any one of the distinctions, Christian actions had to involve “extending help in saving a life; endangering one’s own life; absence of reward, monetary and otherwise; and similar considerations which make the rescuers’ deeds stand out above and beyond what can be termed ordinary help.” In part ambiguous, the criteria leave no doubt that those who saved Jews primarily because of payment do not fit the definition of righteous Christians.
By the fall of 1948, Mengele had made up his mind to leave Germany and build a life elsewhere. Argentina was the preferred choice of sanctuary. There was a groundswell of Nazi sympathy in Argentina. And his father, Karl Sr., who owned a firm that manufactured agricultural equipment, thought that though his company had no branches in Argentina, he had made several business connections there that Josef might develop.

Browning describes the creation of the extermination camps, which were responsible for the largest number of deaths in the Final Solution, as bringing together three separate developments within the Third Reich: the concentration camps which had been established in Germany since 1933; an expansion of the gassing technology of the Nazi euthanasia programme to provide killing mechanism of greater efficiency and psychological detachment; and the creation of "factories of death" to be fed endless streams of victims by mass uprooting and deportation that utilized the experience and personnel from earlier population resettlement programmes—especially the HSSPF and Adolf Eichmann's RSHA for "Jewish affairs and evacuations".[115]
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 extraordinary aspect of the journey to the death camps was that the Nazis often charged Jews deported from Western Europe train fare as third class passengers under the guise that they were being "resettled in the East." The SS also made new arrivals in the death camps sign picture postcards showing the fictional location "Waldsee" which were sent to relatives back home with the printed greeting: "We are doing very well here. We have work and we are well treated. We await your arrival."
SS-Obergruppenführer Reinhard Heydrich, head of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb.[256][257] The meeting had been scheduled for 9 December 1941, and invitations had been sent on 29 November, but it had been postponed.[258]
Dr Daniel Romero Muñoz, who led the team that identified Mengele’s remains in 1985, saw an opportunity to put them to use. Several months ago, the head of the department of legal medicine at the University of São Paulo’s Medical School obtained permission to use them in his forensic medical courses. Today, his students are now learning their trade studying Mengele’s bones and connecting them to the life story of the man called the “angel of death”.
Historians disagree as to when and how the Nazi leadership decided that the European Jews should be exterminated. The controversy is commonly described as the functionalism versus intentionalism debate which began in the 1960s, and subsided thirty years later. In the 1990s, the attention of mainstream historians moved away from the question of top executive orders triggering the Holocaust, and focused on factors which were overlooked earlier, such as personal initiative and ingenuity of countless functionaries in charge of the killing fields. No written evidence of Hitler ordering the Final Solution has ever been found to serve as a "smoking gun", and therefore, this one particular question remains unanswered.[105]
I think this should stay on school book lists because some kids these days see the Holocaust as something that happened a long time ago that is meaningless now, without realizing that genocides and racial motivated violence still happens every day. I think it seems to them like just another thing they have to learn about along with The Hundred Years War and the Crusades.
To those whose knowledge of the Holocaust consists, essentially, of the fact that Hitler killed the Jews, it often comes as a surprise to learn that, in the first seven and a half years of Nazi rule in Germany, he did no such killing: Jews were not deliberately murdered by the Nazi regime until the invasion of the Soviet Union in June 1941. In Karl Schleunes’ famous phrase, there was a “twisted road to Auschwitz,” with a gradual but by no means direct path to continental genocide. For the first few years of Nazi rule in Germany”Hitler came to power in January 1933 as chancellor and consolidated his rule after the death of President von Hindenburg a year later”Nazi policy aimed “merely” at the removal of Jews from positions of authority, especially in the state sector, with such removal constantly reinforced by the totalitarian regime’s propaganda and its police terrorism.

A memorandum dated July 31, 1941, from Hitler’s top commander Hermann Goering to Reinhard Heydrich, chief of the SD (the security service of the SS), referred to the need for an Endlösung (final solution) to “the Jewish question.” Beginning in September 1941, every person designated as a Jew in German-held territory was marked with a yellow star, making them open targets. Tens of thousands were soon being deported to the Polish ghettoes and German-occupied cities in the USSR.
Mengele injected chemicals into the eyes of children in an attempt to change their eye color. Unfortunately a strict veil of secrecy over the experiments enabled Mengele to do his work more effectively.The full extent of his gruesome work will never be known because the records he sent to Dr. Von Verschuer at the Kaiser Wilhelm Institute were shipped out in two truckloads and destroyed by the latter.
In 1942, Auschwitz II (Birkenau), originally intended to house slave laborers, began to be used instead as a combined labor camp and extermination camp.[23][24] Prisoners were transported there by rail from all over German-occupied Europe, arriving in daily convoys.[25] By July 1942, SS doctors were conducting "selections" where incoming Jews were segregated, and those considered able to work were admitted into the camp while those deemed unfit for labor were immediately killed in the gas chambers.[26] The arrivals that were selected to die, about three-quarters of the total,[a] included almost all children, women with small children, pregnant women, all the elderly, and all of those who appeared (in a brief and superficial inspection by an SS doctor) to be not completely fit and healthy.[28][29]
