However, the route to a professorship was interrupted in 1938-1939 when he began his military experience by serving six months with a specially trained mountain light-infantry regiment. In 1940 he was placed in the reserve medical corps, following which he served three years with a Waffen SS unit. It was during this time period he was wounded and declared medically unfit for combat. Because he had acquitted himself brilliantly in the face of the enemy during the Eastern Campaign, he was promoted to the rank of captain.
Reichsführer-SS Heinrich Himmler visited Auschwitz-Birkenau on July 17 and 18, 1942 and watched the gassing of 449 women and children in Bunker No. 1, according to his biographer Peter Padfield. On July 23, 1942, Himmler ordered the quarantine of the Birkenau camp because of a typhus epidemic, but the gassing of the Jews continued. On December 28, 1942, Himmler issued an order that the death rate "must be reduced at all costs" according to document 2172-PS that was introduced at the Nuremberg IMT. He meant the death rate from typhus; the gassing of the Jews did not stop.
For the first time, camps were created specifically for Jews. Their conditions were far worse than other camps. The implicit intention was that the inmates would die there. Increasing numbers of Jews in Poland were relocated in ghettos. Non-Jewish Poles were also deported from their farms and villages to make room for ‘pure’ ethnic Germans to populate the new territory.

Our many Jewish friends and acquaintances are being taken away in droves. The Gestapo is treating them very roughly and transporting them in cattle cars to Westerbork. . . .The people get almost nothing to eat, much less to drink, as water is available only one hour a day, and there’s only one toilet and sink for several thousand people. Men and women sleep in the same room, and women and children often have their heads shaved. . . . If it’s that bad in Holland, what must it be like in those faraway and uncivilized places where the Germans are sending them? We assume that most of them are being murdered. The English radio says they’re being gassed.
In March 1951, the government of Israel requested $1.5 billion from the Federal Republic of Germany to finance the rehabilitation of 500,000 Jewish survivors, arguing that Germany had stolen $6 billion from the European Jews. Israelis were divided about the idea of taking money from Germany. The Conference on Jewish Material Claims Against Germany (known as the Claims Conference) was opened in New York, and after negotiations, the claim was reduced to $845 million.[463][464]
As Siksnianas led Freund through the woods, he told an astonishing story about a group of prisoners who had reportedly tunneled to freedom and joined partisan fighters hiding out in the forest. But when Freund asked to see exactly how they made it out, he got only shrugs. No one could show him; no one knew. Because a tunnel had never been definitively located and documented, the story had come to take on the contours of a fable, and three-quarters of a century on, it seemed destined to remain a legend without any verifiable evidence to back it up—a crucial piece of the historical record, lost to time.
Yet any projection of Anne Frank as a contemporary figure is an unholy speculation: it tampers with history, with reality, with deadly truth. “When I write,” she confided, “I can shake off all my cares. My sorrow disappears, my spirits are revived!” But she could not shake off her capture and annihilation, and there are no diary entries to register and memorialize the snuffing of her spirit. Anne Frank was discovered, seized, and deported; she and her mother and sister and millions of others were extinguished in a program calculated to assure the cruellest and most demonically inventive human degradation. The atrocities she endured were ruthlessly and purposefully devised, from indexing by tattoo through systematic starvation to factory-efficient murder. She was designated to be erased from the living, to leave no grave, no sign, no physical trace of any kind. Her fault—her crime—was having been born a Jew, and as such she was classified among those who had no right to exist: not as a subject people, not as an inferior breed, not even as usable slaves. The military and civilian apparatus of an entire society was organized to obliterate her as a contaminant, in the way of a noxious and repellent insect. Zyklon B, the lethal fumigant poured into the gas chambers, was, pointedly, a roach poison.
For Kanin, this kind of rumination was “an embarrassing piece of special pleading. . . . The fact that in this play the symbols of persecution and oppression are Jews is incidental, and Anne, in stating the argument so, reduces her magnificent stature.” And so it went throughout. The particularized plight of Jews in hiding was vaporized into what Kanin called “the infinite.” Reality—the diary’s central condition—was “incidental.” The passionately contemplative child, brooding on concrete evil, was made into an emblem of evasion. Her history had a habitation and a name; the infinite was nameless and nowhere.
Concentration camps began to incarcerate ‘habitual criminals’ in addition to political prisoners. Goebbels stepped up anti-Semitic propaganda with a traveling exhibition which cast Jews as the enemy. Nearly half a million people attended. Some guessed worse would come. Winston Churchill criticised British relations with Germany, warning of ‘great evils of racial and religious intolerance’, though many colleagues complained of his ‘harping on’ about Jews.
The economic strains of the Great Depression led some in the German medical establishment to advocate murder (euphemistically called "euthanasia") of the "incurable" mentally and physically disabled as a cost-saving measure to free up funds for the curable.[66] By the time the National Socialist German Workers' Party, or Nazi Party,[j] came to power in 1933, there was already a tendency to seek to save the racially "valuable", while ridding society of the racially "undesirable".[68] The party had originated in 1920[67] as an offshoot of the völkisch movement, and it adopted that movement's antisemitism.[69] Early antisemites in the party included Dietrich Eckart, publisher of the Völkischer Beobachter, the party's newspaper, and Alfred Rosenberg, who wrote antisemitic articles for it in the 1920s. Rosenberg's vision of a secretive Jewish conspiracy ruling the world would influence Hitler's views of Jews by making them the driving force behind communism.[70] The origin and first expression of Hitler's antisemitism remain a matter of debate.[71] Central to his world view was the idea of expansion and lebensraum (living space) for Germany. Open about his hatred of Jews, he subscribed to the common antisemitic stereotypes.[72] From the early 1920s onwards, he compared the Jews to germs and said they should be dealt with in the same way. He viewed Marxism as a Jewish doctrine, said he was fighting against "Jewish Marxism", and believed that Jews had created communism as part of a conspiracy to destroy Germany.[73]
Raphael Lemkin, a holocaust survivor who worked on the Nuremberg Trials, coined the term genocide and spent 4 years pushing for it to be added to international law. As Champetier de Ribes, the French Prosecutor at the Nuremberg Trials explained “This [was] a crime so monstrous, so undreamt of in history throughout the Christian era up to the birth of Hitlerism that the term ‘genocide’ has had to be coined to define it.” Ultimately, in 1948 The United Nations Convention on the Prevention and Punishment of Genocide was adopted, and it entered into force in 1951. The convention defined genocide in legal terms based on Lemkin’s work, and is the basis for genocide prevention efforts today.
Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments,[33] with a particular interest in locating sets of twins.[34] In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling a tune.[35][31] He was also one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-based pesticide that was used for the mass killings in the Birkenau gas chambers. He served in this capacity at the gas chambers located in crematoria IV and V.[36]
