Eichmann received various levels of cooperation from each of the various occupied governments. But in countries such as Holland, Belgium, Albania, Denmark, Finland and Bulgaria, some Jews were saved from their deaths by the action of the sympathetic populace and government officials. Denmark’s government and populace were exemplary in their heroism in saving Jews. In other countries such as Poland, Greece, France, and Yugoslavia, the deportation of Jews to the death camps was facilitated by the cooperation of the government.

The second is the saris, usually translated as “eunuch,” whose despair comes from childlessness. To him the prophet promises “a place and a name,” in Hebrew yad va-shem—a phrase, sometimes rendered “everlasting memorial,” that gives its name to Israel’s Holocaust memorial museum. Don’t worry, Isaiah is saying, you may think that your lack of progeny means that your name won’t live on. But God promises it will live on forever.

Which made him all the more intrigued to hear, two years ago, about a new research project led by Jon Seligman, of the Israel Antiquities Authority, at the site of Vilnius’s Great Synagogue, a once towering Renaissance-Baroque structure dating to the 1630s. The synagogue, which had also housed a vast library, kosher meat stalls and a communal well, had at one time been the crown jewel of the city, itself a center of Jewish life in Eastern Europe—the “Jerusalem of the North.” By one estimate, at the turn of the 20th century Vilnius was home to some 200,000 people, half of them Jewish. But the synagogue was damaged after Hitler’s army captured the city in June 1941 and herded the Jewish population into a pair of walled ghettos, whom it then sent, in successive waves, to Ponar. After the war the Soviets razed the synagogue entirely; today an elementary school stands in its place.

This is not about people acting out a crime of passion. This is planned and rationalized violence — a cultural brainwashing. The rationalization is always that the victims are not truly human, not worthy of the same protections of the law. It’s interesting that the Nazis are often linked to Christianity, especially the Catholic Church. But it is precisely the teachings of the Church that stand in the way of such dehumanization. This is something that Mengele himself knew, as he was raised in a Catholic family. In fact, in his post-WWII journal, Mengele specifically wrote, “We had to liberate Germanic history from Roman and Catholic influences.”
Peter Longerich argues that the search for a finite date on which the Nazis embarked upon the extermination of the Jews is futile, in his book Holocaust: The Nazi Persecution and Murder of the Jews (2011). Longerich writes: "We should abandon the notion that it is historically meaningful to try to filter the wealth of available historical material and pick out a single decision" that led to the Holocaust.[116][117]

When exactly Hitler settled on straightforward murder as a means of removal has been harder to pinpoint. As Yale historian Timothy Snyder writes, “It cannot be stressed enough that the Nazis did not know how to eradicate the Jews when they began the war against the Soviet Union [in the summer of 1941]… They could not be confident that SS men would shoot women and children in large numbers.” But as Operation Barbarossa, the name for the Nazi invasion of the U.S.S.R, proved during the mass shootings of June 1941 and the massacres at Kiev in September, the Order Police and Einsatzgrüppen were more than willing to commit mass murders. This meant Hitler could take the solution to the Jewish problem to its “furthest extremes,” in the words of Philipp Bouhler, the senior Nazi official responsible for the euthanasia program that killed more than 70,000 handicapped German people.
They set off at 11 p.m., in groups of ten. The first group emerged from the tunnel without incident. Zeidel recalled slithering on his stomach toward the edge of the camp. He scarcely dared to exhale; his heart slammed against his chest wall. Later, Farber would speculate that it was the snap of a twig that alerted their captors to the escape. Dogim attributed it to a blur of movement spotted by the guards.

Mengele became interested in using twins for medical research through his mentor, Verschuer. Verschuer himself was famous for experimenting with identical and fraternal twins in order to trace the genetic origins of various diseases. During the 1930s, twin research was seen as an ideal tool in weighing the factors of human heredity and environment. Mengele and his mentor had performed a number of legitimate research protocols using twins as test subjects throughout the 1930s. Now, at Auschwitz, with full license to maim or kill his subjects, Mengele performed a broad range of agonizing and often lethal experiments with Jewish and Roma (Gypsy) twins, most of them children.

The match was perfect. The video image of the photograph was imposed precisely over the video image of the skull. It was a face wrapped over a skull, subject over object, an image of life over an image of death. While the images helped to push the probability calculation further in the direction of a definitive identification, they did more than that, for it was the appearance of a previously unseen image that produced the potential for conviction.

These three extermination factories — with Belzec responsible for about 600,000 victims, Sobibor 200,000, Treblinka 900,000 — shared certain features. Like Auschwitz at a later stage, they were equipped with railroad terminals that the trains entered in reverse. The victims were ordered to undress and then led through a corridor to the gas chambers; the gas was composed of carbon monoxide produced by diesel motors. At first, the corpses were buried in mass graves, later they were burnt in crematoria. The similarity to the “euthanasia” program was evident here too. In August 1941, the camps inspector was SS Sturmbannfiihrer Christian Wirth who, like dozens of other specialists of “Operation T4,” was placed under Odilo Globocnik, the commander of the SS for the region of Lublin.

When an outbreak of noma (a gangrenous bacterial disease of the mouth and face) struck the Romani camp in 1943, Mengele initiated a study to determine the cause of the disease and develop a treatment. He enlisted the assistance of prisoner Dr. Berthold Epstein, a Jewish pediatrician and professor at Prague University. The patients were isolated in a separate barracks and several afflicted children were killed so that their preserved heads and organs could be sent to the SS Medical Academy in Graz and other facilities for study. This research was still ongoing when the Romani camp was liquidated and its remaining occupants killed in 1944.[2]
