The Theresienstadt ghetto was established by the Nazis in an 18th century fortress in Czechoslovakia on November 24, 1941. More than 150,000 Jews passed through the ghetto during its four-year existence, which was used as a holding area for eventual murder in Auschwitz. By 1943, rumors began circulating in the international community that the Nazis were exterminating Jews in gas chambers, and that the conditions of the ghettos did not permit survival. The Nazis rebuilt parts of this ghetto to serve as a “showpiece” for propaganda purposes. Flower gardens were planted in the ghetto. Shops, schools, and a cafe were built. When an investigating commission of the International Red Cross came to visit, they did not see a typical ghetto. In July 1944 the Nazis made a documentary propaganda film about life in this ghetto. After the movie was completed, most of the Jewish “actors” were shipped to their death at Auschwitz.

After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews.[143] The ghettos were formed and closed off from the outside world at different times and for different reasons.[196][197] For example, the Łódź ghetto was closed in April 1940,[143] to force the Jews inside to give up money and valuables;[198] the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto),[199] but this did not happen until November 1940;[143] and the Kraków ghetto was not established until March 1941.[200] The Warsaw Ghetto contained 380,000 people[143] and was the largest ghetto in Poland; the Łódź Ghetto was the second largest,[201] holding between 160,000[202] to 223,000.[203] Because of the long drawn-out process of establishing ghettos, it is unlikely that they were originally considered part of a systematic attempt to eliminate Jews completely.[204]

Auschwitz, perhaps the most notorious and lethal of the concentration camps, was actually three camps in one: a prison camp (Auschwitz I), an extermination camp (Auschwitz II–Birkenau), and a slave labour camp (Auschwitz III–Buna-Monowitz). Upon arrival, Jewish prisoners faced what was called a Selektion. A German doctor presided over the selection of pregnant women, young children, the elderly, handicapped, sick, and infirm for immediate death in the gas chambers. As necessary, the Germans selected able-bodied prisoners for forced labour in the factories adjacent to Auschwitz, where one German company, IG Farben, invested 700 million Reichsmarks in 1942 alone to take advantage of forced labour, a capital investment. The conglomerate presumed that slave labour would be a permanent part of the German economy. Deprived of adequate food, shelter, clothing, and medical care, these prisoners were literally worked to death. Periodically, they would face another Selektion. The Nazis would transfer those unable to work to the gas chambers of Birkenau.
The biblical term shoah (Hebrew: שׁוֹאָה), meaning "destruction", became the standard Hebrew term for the murder of the European Jews, first used in a pamphlet in 1940, Sho'at Yehudei Polin ("Sho'ah of Polish Jews"), published by the United Aid Committee for the Jews in Poland.[11] On 3 October 1941 the cover of the magazine The American Hebrew used the phrase "before the Holocaust", apparently to refer to the situation in France,[12] and in May 1943 The New York Times, discussing the Bermuda Conference, referred to the "hundreds of thousands of European Jews still surviving the Nazi Holocaust".[13] In 1968 the Library of Congress created a new category, "Holocaust, Jewish (1939–1945)".[14] The term was popularized in the United States by the NBC mini-series Holocaust (1978), about a fictional family of German Jews,[15] and in November 1978 the President's Commission on the Holocaust was established.[16] As non-Jewish groups began to include themselves as Holocaust victims too, many Jews chose to use the terms Shoah or Churban instead.[12][g] The Nazis used the phrase "Final Solution to the Jewish Question" (German: die Endlösung der Judenfrage).[18]
Browning describes the creation of the extermination camps, which were responsible for the largest number of deaths in the Final Solution, as bringing together three separate developments within the Third Reich: the concentration camps which had been established in Germany since 1933; an expansion of the gassing technology of the Nazi euthanasia programme to provide killing mechanism of greater efficiency and psychological detachment; and the creation of "factories of death" to be fed endless streams of victims by mass uprooting and deportation that utilized the experience and personnel from earlier population resettlement programmes—especially the HSSPF and Adolf Eichmann's RSHA for "Jewish affairs and evacuations".[115]
Wonderful book, the like of which I haven't seen elsewhere. So many wonderful passages, insights into life such as you rarely find anywhere. Anne's ruminations captured here were for herself, from the heart. Writing this helped so much in making her life tolerable during this very difficult period in her life. Toward the end, I found it difficult to plow to the end, knowing that she tragically did not survive. However, she was unaware that their arrest was imminent, so the unfortunate ending is not implicit in Anne's writing. She just may as well have survived and gone on to have the wonderful life and career she very much deserved. I have read a lot about WW II, but this book succeeded in doing what all the other readings did not for me -- it made me feel that I was living through it myself.

The Majdanek camp served from time to time as a killing site for Jews residing in the Generalgouvernement. In its gas chambers, the SS killed tens of thousands of Jews, primarily forced laborers too weak to work. The SS and police killed at least 152,000 people, mostly Jews, but also a few thousand Roma (Gypsies), in gas vans at the Chelmno killing center about thirty miles northwest of Lodz. In the spring of 1942, Himmler designated Auschwitz II (Auschwitz-Birkenau) as a killing facility. SS authorities murdered approximately one million Jews from various European countries at Auschwitz-Birkenau.

Mengele's name was mentioned several times during the Nuremberg trials in the mid-1940s, but the Allied forces believed that he was probably already dead.[79] Irene Mengele and the family in Günzburg also alleged that he had died.[80] Working in West Germany, Nazi hunters Simon Wiesenthal and Hermann Langbein collected information from witnesses about Mengele's wartime activities. In a search of the public records, Langbein discovered Mengele's divorce papers, which listed an address in Buenos Aires. He and Wiesenthal pressured the West German authorities into starting extradition proceedings, and an arrest warrant was drawn up on 5 June 1959.[81][82] Argentina initially refused the extradition request because the fugitive was no longer living at the address given on the documents; by the time extradition was approved on 30 June, Mengele had already fled to Paraguay and was living on a farm near the Argentine border.[83]
The Nazis attempted to quell increasing reports of the Final Solution by inviting the International Red Cross to visit Theresienstadt, a ghetto in Czechoslovakia containing prominent Jews. A Red Cross delegation toured Theresienstadt in July 1944 observing stores, banks, cafes, and classrooms which had been hastily spruced-up for their benefit. They also witnessed a delightful musical program put on by Jewish children. After the Red Cross departed, most of the ghetto inhabitants, including all of the children, were sent to be gassed and the model village was left to deteriorate.
After the arrest of the eight people in hiding, helpers Miep Gies and Bep Voskuijl found Anne's writings in the Secret Annex. Miep held on to Anne's diaries and papers and kept them in a drawer of her desk. She hoped that she would one day be able to return them to Anne. When she learned that Anne had died in the Bergen-Belsen concentration camp, she gave all the notebooks and papers to Anne's father, Otto Frank.
After the U.S. government refused to permit the passenger’s refuge, the St. Louis left Cuba for Europe. The St. Louis sailed so close to Florida that they could see the lights of Miami. The passengers were able to find refuge in other European countries so they didn’t have to return to Germany. Great Britain took 288, the Netherlands admitted 181; Belgium took 214, and 224 passengers found temporary refuge in France. When  Germany invaded Western Europe, 532 of the original passengers were trapped. Just over half survived the Holocaust.
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.
That the designated guru replied, year after year, to embarrassing and shabby effusions like these may open a new pathway into our generally obscure understanding of the character of Otto Frank. His responses—from Basel, where he had settled with his second wife—were consistently attentive, formal, kindly. When Wilson gave birth, he sent her a musical toy, and he faithfully offered a personal word about her excitements as she supplied them: her baby sons, her dance lessons, her husband’s work on commercials, her freelance writing. But his letters were also political and serious. It is good, he wrote in October, 1970, to take “an active part in trying to abolish injustices and all sorts of grievances, but we cannot follow your views regarding the Black Panthers.” And in December, 1973, “As you can imagine, we were highly shocked about the unexpected attack of the Arabs on Israel on Yom Kippur and are now mourning with all those who lost members of their families.” Presumably he knew something about losing a family. Wilson, insouciantly sliding past these faraway matters, was otherwise preoccupied, “finding our little guys sooo much fun.”
Of all the aspects of Mengele’s character which are of interest, his research on twins is the focus of the C.A.N.D.L.E.S. organization. Beginning in 1944, twins were selected and placed in special barracks. Some of those selected - like Irene and Rene Guttman were already in the camp. Others like Eva and Miriam Mozes were selected on the ramp and placed in the twins barracks. It is believed that Mengele had worked with twins under Verschuer at the University of Frankfurt. Auschwitz offered Mengele unlimited number of specimens where twins could be studied at random. According to Dr. Miklos Nyiszli in Auschwitz: A Doctor's Eyewitness Account, twins provided the perfect experimental specimens. One could serve as a control while the other endured the experiments. It was well known in the camp that when a twin went to the infirmary, (s)he never returned and that the other twin disappeared too (Eva Mozes Kor, Echoes from Auschwitz). Nyiszli describes the shots of phenol which were used to kill the second twin.

Always delicately respectful of Frank’s dignity and rights—and always mindful of the older man’s earlier travail—Levin had promised that he would step aside if a more prominent playwright, someone “world famous,” should appear. Stubbornly and confidently, he went on toiling over his own version. As a novelist, he was under suspicion of being unable to write drama. (In after years, when he had grown deeply bitter, he listed, in retaliation, “Sartre, Gorky, Galsworthy, Steinbeck, Wilder!”) Though there are many extant drafts of Levin’s play, no definitive script is available; both publication and performance were proscribed by Frank’s attorneys. A script staged without authorization by the Israel Soldiers’ Theatre in 1966 sometimes passes from hand to hand, and reads well: moving, theatrical, actable, professional. This later work was not, however, the script submitted in the summer of 1952 to Cheryl Crawford, one of a number of Broadway producers who rushed in with bids in the wake of the diary’s acclaim. Crawford, an eminent co-founder of the Actors Studio, initially encouraged Levin, offering him first consideration and, if his script was not entirely satisfactory, the aid of a more experienced collaborator. Then—virtually overnight—she rejected his draft outright. Levin was bewildered and infuriated, and from then on he became an intractable and indefatigable warrior on behalf of his play—and on behalf, he contended, of the diary’s true meaning. In his Times review he had summed it up stirringly as the voice of “six million vanished Jewish souls.”

So who was Kitty? Scholars are divided. Some believe “Kitty” refers to Anne’s prewar friend, Käthe "Kitty" Egyedi. Others disagree, believing that Anne borrowed the name from her favorite book series, Joop ter Heul, in which the title character’s best friend was named Kitty. Egyedi, who survived the Theresienstadt concentration camp, later said that she did not believe the letters were meant for her.
Approximately a half million Gypsies (a dark-skinned, Caucasian ethnic group targeted by the Nazis) were murdered out of approximately 1.6 million who were living in Europe. The Gypsies in Germany and the occupied territories of the German War machine were subjected to many of the same persecutions as the Jews: restrictive, discriminatory laws, isolation and internment, and mass executions at their camp sites, in labor camps and death camps.
Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]
Finland was pressured in 1942 to hand over its 150–200 non-Finnish Jews to Germany. After opposition from the government and public, eight non-Finnish Jews were deported in late 1942; only one survived the war.[173] Japan had little antisemitism in its society and did not persecute Jews in most of the territories it controlled. Jews in Shanghai were confined, but despite German pressure they were not killed.[174]

At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]

“Instead of immigration there is now a further possible solution to which the Fuhrer has already signified his consent. Namely deportation to the East. Although this should be regarded merely as an interim measure, it will provide us with the practical experience which will be especially valuable in connection with the future final solution. In the course of the practical implementation of the final solution Europe will be combed from West to East.”
Mengele is known as the “Angel of Death,” or sometimes as the “White Angel,” for his coldly cruel demeanor on the ramp. He is associated more closely with this “selection duty” than any other medical officer at Auschwitz, although by most accounts he performed this task no more often than any of his colleagues. The association is partially explained by his postwar notoriety. The pervasive image of Mengele at the ramp in so many survivors' accounts has also to do with the fact that Mengele often appeared “off-duty” in the selection area whenever trainloads of new prisoners arrived at Auschwitz, searching for twins.
But how he would enact such a plan wasn’t always clear. For a brief period, the Führer and other Nazi leaders toyed with the idea of mass deportation as a method of creating a Europe without Jews (Madagascar and the Arctic Circle were two suggested relocation sites). Deportation still would’ve resulted in thousands of deaths, though perhaps in less direct ways.
It is not clear which of the four gas chambers at Birkenau that Litwinska was referring to. The Krema IV and Krema V gas chambers were on the ground floor and had "small windows high up near the roof" where the gas pellets were thrown in by the SS men. But neither of these two gas chambers had a "gas chamber chute" for dumping the victims into the gas chamber from "tipper-type lorries," which Americans would call dump trucks.

I followed Freund up a short slope and past a trench where prisoners had been lined up and shot. It was now a barely perceptible dip in the loam. ­Freund stepped gingerly around it. In the distance, a train whistle howled, followed by the huff of a train, shuddering over tracks that had carried prisoners to their deaths decades earlier. Freund waited for it to pass. He recalled that he’d spent nearly a month researching the site—but “a few days,” he said, “is plenty of time to think about how many people died here, the amount of blood spilled.”

Ultimately, one must surely conclude that the unparalleled enormities carried out by the Nazis took place because the First World War destroyed Germany’s traditional elite structure, permitting, in the context of the Depression, the rise of an extremist movement at the absolute fringes of political life which would never otherwise have come to power. Almost precisely the same thing occurred, for the same reasons, in Russia with the Bolshevik revolution and the rise of Stalin to supreme power just over a decade later. In the English-speaking world, fortunately, the legacy of internalized liberalism, enhanced by the fact that its nations were victorious in the First World War and their institutions left intact, kept the traditional governing structures viable and gave radical fringe groups no opportunity to gather political power. Arguably, too, the deep wound of 1914-1918, which caused so many horrors in Europe, was not fully healed until the fall of Communism in 1990, if even then.

Mengele injected chemicals into the eyes of children in an attempt to change their eye color. Unfortunately a strict veil of secrecy over the experiments enabled Mengele to do his work more effectively.The full extent of his gruesome work will never be known because the records he sent to Dr. Von Verschuer at the Kaiser Wilhelm Institute were shipped out in two truckloads and destroyed by the latter.
The logistics of the mass murder turned Germany into what Michael Berenbaum called a "genocidal state".[34] Eberhard Jäckel wrote in 1986 that it was the first time a state had thrown its power behind the idea that an entire people should be wiped out.[h] Anyone with three or four Jewish grandparents was to be exterminated,[36] and complex rules were devised to deal with Mischlinge ("mixed breeds": half and quarter Jews).[37] Bureaucrats identified who was a Jew, confiscated property, and scheduled trains to deport them. Companies fired Jews and later used them as slave labor. Universities dismissed Jewish faculty and students. German pharmaceutical companies tested drugs on camp prisoners; other companies built the crematoria.[34] As prisoners entered the death camps, they were ordered to surrender all personal property, which was catalogued and tagged before being sent to Germany for reuse or recycling.[38] Through a concealed account, the German National Bank helped launder valuables stolen from the victims.[39]
It is estimated that by 1942 Einsatzgruppen had killed more than 1 million Soviet troops. These victims were either shot or gassed. Jews were not the only ones killed. People who opposed Hitler were also murdered. 20th century techniques of mass production were applied in the Final Solution. Engineers of the Final Solution used these ways to cheaply and efficiently murder millions of Jews there were many ways the Nazis murdered people. Some ways were crematoriums, electrocution, injections, flame throwers, hand grenades, and gas chambers. Units of the S.S. that were specially trained followed German troops called the first wave. These squads made up the Einsatzgruppen. Nazis genocide was targeted towards Jews mass murder was targeted towards other Non-Aryans.      
The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger.[242] The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals.[243] By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people.[244] The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev,[245] where 33,771 Jews were killed in a single operation on 29–30 September 1941.[246][n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings.[248] Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot.[249] By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.[250]

These mass murders took place in small cottages situated outside the Birkenau camp in the woods…All the SS physicians on duty in the camp took turns to participate in the gassing, which were called Sonderaction, “special action”....When the transport with the people who were destined to be gassed arrived as the railway ramp, the SS officer selected, from among the new arrivals, persons fit to work, while the rest - old people, all children, women with children in their arms and other persons not deemed fit to work- were loaded on to lorries and driven to the gas-chamber.
He inspired Anne: she planned after the war to publish a book about her time in hiding. She also came up with a title: Het Achterhuis, or The Secret Annex. She started working on this project on 20 May 1944. Anne rewrote a large part of her diary, omitted some texts and added many new ones. She wrote the new texts on separate sheets of paper. She describes the period from 12 June 1942 to 29 March 1944. Anne worked hard: in a those few months, she wrote around 50,000 words, filling more than 215 sheets of paper.

Jews would be “utilised for work in the East… [The] sexes [will be] separated. Jews capable of work will be moved into these areas as they build roads, during which a large proportion will no doubt drop out through natural reduction. The remnant that eventually remains will require suitable treatment…The evacuated Jews will first be taken, group by group, to so-called transit ghettos, in order to be transported further east from there.”
“Who has made us Jews different from all other people? Who has allowed us to suffer so terribly up until now? It is God who has made us as we are, but it will be God, too, who will raise us up again. Who knows? It might even be our religion from which the world and all peoples learn good, and for that reason and only that reason do we suffer. We can never become just Netherlanders, or just English or representatives of any country for that matter. We will always remain Jews, but we want to, too.” – April 11, 1944
While the Nazis murdered other national and ethnic groups, such as a number of Soviet prisoners of war, Polish intellectuals, and gypsies, only the Jews were marked for systematic and total annihilation. Jews were singled out for "Special Treatment" (Sonderbehandlung), which meant that Jewish men, women and children were to be methodically killed with poisonous gas. In the exacting records kept at the Auschwitz death camp, the cause of death of Jews who had been gassed was indicated by "SB," the first letters of the two words that form the German term for "Special Treatment."
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]
