The photo above was taken while Mengele was home on leave, after spending 5 months at Auschwitz-Birkenau. He is wearing an Iron Cross medal on the pocket of his uniform. Mengele was very proud of his medals; he earned the Iron Cross 2nd Class shortly after he was sent to the Ukraine in June 1941 at the time of the German invasion of the Soviet Union. In January 1942, Mengele joined the prestigious 5th SS Panzer Division, nicknamed the Viking Division. In July 1942, he was awarded the Iron Cross 1st Class after he pulled two wounded soldiers out of a burning tank under enemy fire on the battlefield, and administered medical first aid to them.
Otto Frank later described what it was like when the Nazis entered the annex in which he had been hiding. He said an SS man picked up a portfolio and asked whether there were any jewels in it. When Otto Frank said it only contained papers, the SS man threw the papers (and Anne Frank’s diary) on the floor, walking away with silverware and a candlestick in his briefcase. “If he had taken the diary with him,” Otto Frank recalled, “no one would ever have heard of my daughter.”
The Nazis established ghettos in occupied Poland. Polish and western European Jews were deported to these ghettos. During the German invasion of the Soviet Union in 1941, mobile killing squads (Einsatzgruppen) began killing entire Jewish communities. The methods used, mainly shooting or gas vans, were soon regarded as inefficient and as a psychological burden on the killers.
At Auschwitz, a large new camp was already under construction to be known as Auschwitz II (Birkenau). This would become the future site of four large gas chambers to be used for mass extermination. The idea of using gas chambers originated during the Euthanasia Program, the so-called "mercy killing" of sick and disabled persons in Germany and Austria by Nazi doctors.
The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators. Holocaust is a word of Greek origin meaning “sacrifice by fire.” The Nazis, who came to power in Germany in January 1933, believed that Germans were “racially superior” and that the Jews, deemed “inferior,” were an alien threat to the so-called German racial community.
Systematic examinations of rescuers have actually shown a high degree of heterogeneity among individuals. Rescuers came from divergent social backgrounds, varied widely in terms of political and religious involvements, and displayed different levels of friendship and animosity toward Jews. None of these variables has turned out to be a reliable predictor of the sort of person who was more or less likely to rescue Jews.
Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000. In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans, although the partisan movements did not always welcome them. An estimated 20,000 to 30,000 joined the Soviet partisan movement. One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers. Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[r]
Seven months later, November 1943, the U.S. Congress held hearings concerning the U.S. State Department's total inaction regarding the plight of European Jews. President Franklin Roosevelt responded to the mounting political pressure by creating the War Refugee Board (WRB) in January 1944 to aid neutral countries in the rescue of Jews. The WRB helped save about 200,000 Jews from death camps through the heroic efforts of persons such as Swedish diplomat Raoul Wallenberg working tirelessly in occupied countries.
In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary "euthanasia"; after the war this program was named Aktion T4. It was named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered. T4 was mainly directed at adults, but the "euthanasia" of children was also carried out. Between 1939 and 1941, 80,000 to 100,000 mentally ill adults in institutions were killed, as were 5,000 children and 1,000 Jews, also in institutions. In addition there were specialized killing centres, where the deaths were estimated at 20,000, according to Georg Renno, the deputy director of Schloss Hartheim, one of the "euthanasia" centers, or 400,000, according to Frank Zeireis, the commandant of the Mauthausen concentration camp. Overall, the number of mentally and physically handicapped murdered was about 150,000.
