He had a wide variety of other research interests. Among these was a fascination with heterochromia, a condition in which the irises of an individual's eyes differ in coloration. Throughout his stay in Auschwitz, Mengele collected the eyes of his murdered victims, in part to furnish “research material” to colleague Karin Magnussen, a KWI researcher of eye pigmentation. He himself also conducted several experiments in an attempt to unlock the secret of artificially changing eye color. He also zealously documented in camp inmates the progression of the disease Noma, a type of gangrene which destroys the mucous membrane of the mouth and other tissues.
The Mossad was still a young agency, short of resources and manpower. Moreover, as Aharoni later put it in testimony for the Mossad’s history department, “When Isser began dealing with something, he dealt only with that.” In addition, the agency had been blindsided, knowing nothing about the German scientists and the missiles they were building for Israel’s biggest enemy. Harel mobilized the entire agency to deal with it.

An ardent Nazi, In 1943 Josef Mengele was appointed by Heinrich Himmler to be chief doctor at Birkenau, the supplementary extermination camp at Auschwitz, where he and his staff selected incoming Jews for labor or extermination and where he supervised medical experiments on inmates to discover means of increasing fertility (to increase the German “race”).
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.

It is impossible to determine what Krueger's exact responsibility was in connection with 'Bloody Sunday' [massacre of 12 October 1941]. It is clear that a massacre of such proportions under German civil administration was virtually unprecedented.
There was "practically no resistance" in the ghettos in Poland by the end of 1942, according to Peter Longerich.[305] Raul Hilberg accounted for this by evoking the history of Jewish persecution: as had been the case before, appealing to their oppressors and complying with orders might avoid inflaming the situation until the onslaught abated.[306] Henri Michel argued that resistance consisted not only of physical opposition but of any activity that gave the Jews humanity in inhumane conditions, while Yehuda Bauer defined resistance as actions that in any way opposed the German directives, laws, or conduct.[307] Hilberg cautioned against overstating the extent of Jewish resistance, arguing that turning isolated incidents into resistance elevates the slaughter of innocent people into some kind of battle, diminishes the heroism of those who took active measures to resist, and deflects questions about the survival strategies and leadership of the Jewish community.[308] Timothy Snyder noted that it was only during the three months after the deportations of July–September 1942 that agreement on the need for armed resistance was reached.[309]

Meanwhile, Hitler continued his conquest of Europe, invading Belgium, Holland, Luxembourg and France, placing ever-increasing numbers of Jews under Nazi control. The Nazis then began carefully tallying up the actual figures and also required Jews to register all of their assets. But the overall question remained as to what to do with the millions of Jews now under Nazi control - referred to by the Nazis themselves as the Judenfrage (Jewish question).
At Auschwitz-Birkenau, new arrivals were told to carefully hang their clothing on numbered hooks in the undressing room and were instructed to remember the numbers for later. They were given a piece of soap and taken into the adjacent gas chamber disguised as a large shower room. In place of carbon monoxide, pellets of the commercial pesticide Zyklon-B (prussic acid) were poured into openings located above the chamber upon the cynical SS command - Na, gib ihnen shon zu fressen (All right, give 'em something to chew on). The gas pellets fell into hollow shafts made of perforated sheet metal and vaporized upon contact with air, giving off lethal cyanide fumes inside the chamber which oozed out at floor level then rose up toward the ceiling. Children died first since they were closer to the floor. Pandemonium usually erupted as the bitter almond-like odor of the gas spread upwards with adults climbing on top of each other forming a tangled heap of dead bodies all the way up to the ceiling.
He acted instantly. He sent Otto Frank a copy of “In Search” and in effect offered his services as an unofficial agent to secure British and American publication, asserting his distance from any financial gain; his interest, he said, was purely “one of sympathy.” He saw in the diary the possibility of “a very touching play or film,” and asked Frank’s permission to explore the idea. Frank at first avoided reading Levin’s book, saturated as it was in passions and commitments so foreign to his own susceptibilities. He was not unfamiliar with Levin’s preoccupations; he had seen and liked one of his films. He encouraged Levin to go ahead—though a dramatization, he observed, would perforce “be rather different from the real contents” of the diary. Hardly so, Levin protested: no compromise would be needed; all the diarist’s thoughts could be preserved.
Similarly, in Ordinary Men (1992), Christopher Browning examined the deeds of German Reserve Police Battalion 101 of the Ordnungspolizei ("order police"), used to commit massacres and round-ups of Jews, as well as mass deportations to the death camps. The members of the battalion were middle-aged men of working-class background from Hamburg, who were too old for regular military duty. They were given no special training. During the murder of 1,500 Jews from Józefów in Poland, their commander allowed them to opt out of direct participation. Fewer than 12 men out of a battalion of 500 did so. Influenced by the Milgram experiment on obedience, Browning argued that the men killed out of peer pressure, not bloodlust.[471]

Following the invasion of the Soviet Union in June 1941, Einsatzgruppen and, later, militarized battalions of Order Police officials, moved behind German lines to carry out mass-murder operations against Jews, Roma, and Soviet state and Communist Party officials. German SS and police units, supported by units of the Wehrmacht and the Waffen SS, murdered more than a million Jewish men, women, and children, and hundreds of thousands of others.
Before the the Final Solution the plan the Nazis had was to force the Jews to immigration. In 1940 the nazis planed to ship the Jews to an Island in the Indian ocean called Madagascar. it was not until later they referred to the Final Solution as genocide rather than territorial Final Solution. As the nazis were under cover of the war they developed technology to successfully murder millions of Jews. details were worked out at the Wansee Conference. All Jews in Germanys occupied countries were sent to ghettos as holding areas. Many were sent to camps were they worked under brutal conditions. Many were sent to gas chambers. As the Allies advanced death marches cut down the number of potential survivors. Some of Hitler's objectives were to wage to wars at once one aimed at anyone who objected him the other at the Jews. Hitler's success was credited to planed steps and reaction to those of other world powers. 
“Awesome as they are, therefore, numbers do not in themselves prescribe the singularity of the Holocaust. But they provide a clue. For the proportion of European Jews killed during the Second World War, with roughly one of every three civilian deaths in Europe being that of a Jew, was undoubtedly greater than that of any other people, because of the Nazis’ policy toward them. Unlike the case with any other group, and unlike the massacres before or since, every single one of the millions of targeted Jews was to be murdered. Eradication was to be total. In principle, no Jew was to escape. In this important respect, the Nazis’ assault upon Jewry differed from the campaigns against other peoples and groups; Gypsies, Jehovah’s Witnesses, homosexuals, Poles, Ukrainians, and so on. Assaults on these people could indeed be murderous; their victims number in the millions, and their ashes mingle with those of the Jews of Auschwitz and many other camps across Europe. But Nazi ideology did not require their total disappearance. In this respect, the fate of the Jews was unique.”

4 out of 5 stars to The Diary of a Young Girl, written during the 1940s by Anne Frank. Many are first exposed to this modern-day classic during their middle or high school years, as a way to read a different type of literature from that of an ordinary novel. In this diary, young Anne express her thoughts (both positive and negative) over a two-year period during which her family and friends are in hiding during World War II and the Holocaust. For most of us, this is one of the few ...more
Mengele's research subjects were better fed and housed than the other prisoners, and temporarily spared from execution in the gas chambers.[42] He established a kindergarten for children who were the subjects of his experiments, as well as the preschool children from the Romani camp. The facility provided better food and living conditions than other areas of the camp, and included a children's playground.[43] When visiting his young subjects, he introduced himself as "Uncle Mengele" and offered them sweets,[44] while at the same time being personally responsible for the deaths of an unknown number of victims whom he killed via lethal injection, shootings, beatings, and his deadly experiments.[45] In his 1986 book, Lifton describes Mengele as sadistic, lacking empathy, and extremely antisemitic, believing the Jews should be eliminated entirely as an inferior and dangerous race.[46] Rolf Mengele later claimed that his father had shown no remorse for his wartime activities.[47]
