An emaciated 18-year-old Russian girl looks into the camera lens during the liberation of Dachau concentration camp in 1945. Dachau was the first German concentration camp, opened in 1933. More than 200,000 people were detained between 1933 and 1945, and 31,591 deaths were declared, most from disease, malnutrition and suicide. Unlike Auschwitz, Dachau was not explicitly an extermination camp, but conditions were so horrific that hundreds died every week. #

Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
The term righteous gentile is a reference to the term 'Righteous Among the Nations' that is a honour bestowed by Yad Vashem. Gushee's work is a study of these people, the (very) few in number who risked personal harm to selflessly assist Jews from persecution. This book is full of accounts of such persons, some who succeeded and some who failed. These are extremely challenging, particularly when faced with the question 'what would I do in such a situation?' knowing that what I hope I would do and what I do may not be synonymous. In studying such persons Gushee presents a good overview of the types of people who were in the minority and were righteous Gentiles, including conclusions on the extent religion played a role in their actions.
By now, experimental mobile gas vans were being used by the Einsatzgruppen to kill Jews in Russia. Special trucks had been converted by the SS into portable gas chambers. Jews were locked up in the air-tight rear container while exhaust fumes from the truck's engine were fed in to suffocate them. However, this method was found to be somewhat impractical since the average capacity was less than 50 persons. For the time being, the quickest killing method continued to be mass shootings. And as Hitler's troops advanced deep into the Soviet Union, the pace of Einsatz killings accelerated. Over 33,000 Jews in the Ukraine were shot in the Babi Yar ravine near Kiev during two days in September 1941.
Hitler quickly moved to cement his power by suspending many civil liberties and allowing imprisonment without trial. By March, the first Nazi concentration camp was established at Dachau, not to imprison Jews but to hold political dissidents. Further laws targeted Jews, restricting the jobs they could hold and revoking their German citizenship. Anti-Semitic sentiment increased as the Jewish population was blamed for many of Germany's recent and historical problems.
In 1935, Mengele earned a PhD in anthropology from the University of Munich.[7] In January 1937, he joined the Institute for Hereditary Biology and Racial Hygiene in Frankfurt, where he worked for Dr. Otmar Freiherr von Verschuer, a German geneticist with a particular interest in researching twins.[7] As von Verschuer's assistant, Mengele focused on the genetic factors that result in a cleft lip and palate, or a cleft chin.[10] His thesis on the subject earned him a cum laude doctorate in medicine (MD) from the University of Frankfurt in 1938.[11] (Both of his degrees were revoked by the issuing universities in the 1960s.)[12] In a letter of recommendation, von Verschuer praised Mengele's reliability and his ability to verbally present complex material in a clear manner.[13] The American author Robert Jay Lifton notes that Mengele's published works were in keeping with the scientific mainstream of the time, and would probably have been viewed as valid scientific efforts even outside Nazi Germany.[13]
