“One of the things that I always say is you leave room for the next generation of technology to do things that you can’t fathom,” Freund said. “Look, I’m doing things that my teachers never thought of. I don’t have the chutzpah to think that I know all the answers, and maybe in another generation the technology will improve, people will have better ideas, you know?”

The deportees were forced into rail cars, most of which were windowless, unheated cattle cars, and squeezed in so tightly that most were forced to stand. The doors were then sealed shut from the outside. Neither drinking water nor sanitary facilities were available. Each car held more than 120 people, and many froze or suffocated to death or succumbed to disease during the trip to the camps. The dead were not removed from the cars during the journey because the Nazi bureaucracy insisted that each body entering a car be accounted for at the destination.
The German skill in adapting the 20th century techniques of mass production was applied in engineering the “Final Solution.” In 1941, the engineers of the “Final Solution” utilized these same principles to cheaply and efficiently murder millions of Jews and other “undesirables.” The plants established to carry out this mass murder were the death camps.
An Israeli historian Dina Porat claimed that the Final Solution, i.e.: "the systematic overall physical extermination of Jewish communities one after the other – began in Lithuania" during the massive German chase after the Red Army across the Baltic states in Reichskommissariat Ostland.[53] The subject of the Holocaust in Lithuania has been analysed by Konrad Kweit from USHMM who wrote: "Lithuanian Jews were among the first victims of the Holocaust [beyond the eastern borders of occupied Poland]. The Germans carried out the mass executions [...] signaling the beginning of the 'Final Solution'."[54] About 80,000 Jews were killed in Lithuania by October (including in formerly Polish Wilno) and about 175,000 by the end of 1941 according to official reports.[53]

The deportation of Jews to the ghettos culminated in the policy of extermination the Nazis called the "Final Solution to the Jewish Question", discussed by senior Nazi officials at the Wannsee Conference in Berlin in January 1942. As German forces captured territories in the East, all anti-Jewish measures were radicalized. Under the coordination of the SS, with directions from the highest leadership of the Nazi Party, killings were committed within Germany itself, throughout occupied Europe, and across all territories controlled by the Axis powers. Paramilitary death squads called Einsatzgruppen, in cooperation with Wehrmacht police battalions and local collaborators, murdered around 1.3 million Jews in mass shootings between 1941 and 1945. By mid-1942, victims were being deported from the ghettos in sealed freight trains to extermination camps where, if they survived the journey, they were killed in gas chambers. The killing continued until the end of World War II in Europe in May 1945.
For the German rulers, the ghetto was a temporary measure, a holding pen for the Jewish population until a policy on its fate could be established and implemented. For the Jews, ghetto life was the situation under which they thought they would be forced to live until the end of the war. They aimed to make life bearable, even under the most trying circumstances. When the Nazis prohibited schools, they opened clandestine schools. When the Nazis banned religious life, it persisted in hiding. The Jews used humour as a means of defiance, so too song. They resorted to arms only late in the Nazi assault.
Spurred on by Joseph Goebbels, Nazis used the death of vom Rath as an excuse to conduct the first State-run pogrom against Jews. Ninety Jews were killed, 500 synagogues were burned and most Jewish shops had their windows smashed. The first mass arrest of Jews also occurred as over 25,000 men were hauled off to concentration camps. As a kind of cynical joke, the Nazis then fined the Jews 1 Billion Reichsmarks for the destruction which the Nazis themselves had caused during Kristallnacht.
His “obsession,” as he afterward called it—partly in mockery of the opposition his later views evoked—had its beginning in those repeated scenes of piled-up bodies as he investigated camp after camp. From then on, he could be said to carry the mark of Abel. He dedicated himself to helping the survivors get to Mandate Palestine, a goal that Britain had made illegal. In 1946, he reported from Tel Aviv on the uprising against British rule, and during the next two years he produced a pair of films on the struggles of the survivors to reach Palestine. In 1950, he published “In Search,” an examination of the effects of the European cataclysm on his experience and sensibility as an American Jew. (Thomas Mann acclaimed the book as “a human document of high order, written by a witness of our fantastic epoch whose gaze remained both clear and steady.”) Levin’s intensifying focus on the Jewish condition in the twentieth century grew more and more heated, and when his wife, the novelist Tereska Torres, handed him the French edition of the diary (it had previously appeared only in Dutch) he felt he had found what he had thirsted after: a voice crying up from the ground, an authentic witness to the German onslaught.
The United States Holocaust Memorial Museum defines the Holocaust as the "systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators",[29] distinguishing between the Holocaust and the targeting of other groups during "the era of the Holocaust".[30] According to Yad Vashem, Israel's Holocaust memorial, most historians regard the start of the "Holocaust era" as January 1933, when Hitler was named Chancellor of Germany.[31] Other victims of the Holocaust era include those viewed as inferior, including for reasons of race or ethnicity (such as the Roma, ethnic Poles, Russians, and the disabled); and those targeted because of their beliefs or behavior (such as Jehovah's Witnesses, communists, and homosexuals).[30] Hitler came to see the Jews as "uniquely dangerous to Germany", according to Peter Hayes, "and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it". The persecution and murder of other groups was much less consistent. For example, he writes, the Nazis regarded the Slavs as "sub-human", but their treatment consisted of "enslavement and gradual attrition", while "some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—[were] allotted a favored place in Hitler's New Order".[20]
The killing grounds at Ponar are today part of a memorial site run by the Vilna Gaon Museum, in Vilnius. There is a granite obelisk inscribed with the date of the Soviet liberation of the region, and clusters of candles smoldering in the small shrines on the edge of the burial pits, in honor of the tens of thousands who perished here. A small museum near the entrance to the site collects photographs and testimonies from the camp. One enters the museum prepared to weep, and leaves insensate: The black-and-white images of tangled human limbs in a ditch, the crumpled corpses of children, the disinterred dead piled in wheelbarrows, waiting to be brought to the pyres—the effect of the material is deeply physical and hard to shake.
We were faced with the question: what about the women and children? – I have decided on a solution to this problem. I did not consider myself justified to exterminate the men only – in other words, to kill them or have them killed while allowing the avengers, in the form of their children, to grow up in the midst of our sons and grandsons. The difficult decision had to be made to have this people disappear from the earth.
The Holocaust by bullets (as opposed to the Holocaust by gas)[82] went on in the territory of occupied Poland in conjunction with the ghetto uprisings, irrespective of death camps' quota. In two weeks of July 1942, the Słonim Ghetto revolt, crushed with the help of Latvian, Lithuanian, and Ukrainian Schutzmannschaft, cost the lives of 8,000–13,000 Jews.[83] The second largest mass shooting (to that particular date) took place in late October 1942 when the insurgency was suppressed in the Pińsk Ghetto; over 26,000 men, women and children were shot with the aid of Belarusian Auxiliary Police before the ghetto's closure.[84] During the suppression of the Warsaw Ghetto Uprising (the largest single revolt by Jews during World War II), 13,000 Jews were killed in action before May 1943.[85] Numerous other uprisings were quelled without impacting the pre-planned Nazi deportations actions.[86]
Jews at this time composed only about one percent of Germany's population of 55 million persons. German Jews were mostly cosmopolitan in nature and proudly considered themselves to be Germans by nationality and Jews only by religion. They had lived in Germany for centuries, fought bravely for the Fatherland in its wars and prospered in numerous professions.

Doubleday, meanwhile, sensing complications ahead, had withdrawn as Frank’s theatrical agent, finding Levin’s presence—injected by Frank—too intrusive, too maverick, too independent and entrepreneurial: fixed, they believed, only on his own interest, which was to stick to his insistence on the superiority of his work over all potential contenders. Frank, too, had begun—kindly, politely, and with tireless assurances of his gratitude to Levin—to move closer to Doubleday’s cooler views, especially as urged by Barbara Zimmerman. She was twenty-four years old, the age Anne would have been, very intelligent and attentive. Adoring letters flowed back and forth between them, Frank addressing her as “little Barbara” and “dearest little one.” On one occasion he gave her an antique gold pin. About Levin, Zimmerman finally concluded that he was “impossible to deal with in any terms, officially, legally, morally, personally”—a “compulsive neurotic . . . destroying both himself and Anne’s play.” (There was, of course, no such entity as “Anne’s play.”)

Otto Frank grew up with a social need to please his environment and not to offend it; that was the condition of entering the mainstream, a bargain German Jews negotiated with themselves. It was more dignified, and safer, to praise than to blame. Far better, then, in facing the larger postwar world that the diary had opened to him, to speak of goodness rather than destruction: so much of that larger world had participated in the urge to rage. (The diary notes how Dutch anti-Semitism, “to our great sorrow and dismay,” was increasing even as the Jews were being hauled away.) After the liberation of the camps, the heaps of emaciated corpses were accusation enough. Postwar sensibility hastened to migrate elsewhere, away from the cruel and the culpable. It was a tone and a mood that affected the diary’s reception; it was a mood and a tone that, with cautious yet crucial excisions, the diary itself could be made to support. And so the diarist’s dread came to be described as hope, her terror as courage, her prayers of despair as inspiring. And since the diary was now defined as a Holocaust document, the perception of the cataclysm itself was being subtly accommodated to expressions like “man’s inhumanity to man,” diluting and befogging specific historical events and their motives. “We must not flog the past,” Frank insisted in 1969. His concrete response to the past was the establishment, in 1957, of the Anne Frank Foundation and its offshoot the International Youth Center, situated in the Amsterdam house where the diary was composed, to foster “as many contacts as possible between young people of different nationalities, races and religions”—a civilized and tenderhearted goal that nevertheless washed away into do-gooder abstraction the explicit urge to rage that had devoured his daughter.
Word History: Totality of destruction has been central to the meaning of holocaust since it first appeared in Middle English in the 1300s, used in reference to the biblical sacrifice in which a male animal was wholly burnt on the altar in worship of God. Holocaust comes from Greek holokauston, "that which is completely burnt," which was a translation of Hebrew 'ōlâ (literally "that which goes up," that is, in smoke). In this sense of "burnt sacrifice," holocaust is still used in some versions of the Bible. In the 1600s, the meaning of holocaust broadened to "something totally consumed by fire," and the word eventually was applied to fires of extreme destructiveness. In the 1900s, holocaust took on a variety of figurative meanings, summarizing the effects of war, rioting, storms, epidemic diseases, and even economic failures. Most of these usages arose after World War II, but it is unclear whether they permitted or resulted from the use of holocaust in reference to the mass murder of European Jews and others by the Nazis. This application of the word occurred as early as 1942, but the phrase the Holocaust did not become established until the late 1950s. Here it parallels and may have been influenced by another Hebrew word, šô'â, "catastrophe" (in English, Shoah). In the Bible šô'â has a range of meanings including "personal ruin or devastation" and "a wasteland or desert." Šô'â was first used to refer to the Nazi slaughter of Jews in 1939, but the phrase haš-šô'â, "the catastrophe," became established only after World War II. Holocaust has also been used to translate ḥurbān, "destruction," another Hebrew word used as a name for the genocide of Jews by the Nazis.
Mengele's eye experiments included attempts to change the eye color by injecting chemicals into the eyes of living subjects, and he killed people with heterochromatic eyes so that the eyes could be removed and sent to Berlin for study.[53] His experiments on dwarfs and people with physical abnormalities included taking physical measurements, drawing blood, extracting healthy teeth, and treatment with unnecessary drugs and X-rays.[3] Many of his victims were dispatched to the gas chambers after about two weeks, and their skeletons sent to Berlin for further analysis.[54] Mengele sought out pregnant women, on whom he would perform experiments before sending them to the gas chambers.[55] Witness Vera Alexander described how he sewed two Romani twins together, back to back, in a crude attempt to create conjoined twins;[50] both children died of gangrene after several days of suffering.[56]
