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.
There was "practically no resistance" in the ghettos in Poland by the end of 1942, according to Peter Longerich.[305] Raul Hilberg accounted for this by evoking the history of Jewish persecution: as had been the case before, appealing to their oppressors and complying with orders might avoid inflaming the situation until the onslaught abated.[306] Henri Michel argued that resistance consisted not only of physical opposition but of any activity that gave the Jews humanity in inhumane conditions, while Yehuda Bauer defined resistance as actions that in any way opposed the German directives, laws, or conduct.[307] Hilberg cautioned against overstating the extent of Jewish resistance, arguing that turning isolated incidents into resistance elevates the slaughter of innocent people into some kind of battle, diminishes the heroism of those who took active measures to resist, and deflects questions about the survival strategies and leadership of the Jewish community.[308] Timothy Snyder noted that it was only during the three months after the deportations of July–September 1942 that agreement on the need for armed resistance was reached.[309]
The murder industry began in the Chelmno camp, built in December 1941. Work was carried out in special trucks, where the victims were asphyxiated by exhaust fumes, a method that had been tried before on those whose lives were deemed useless (the “Euthanasia Pro­gram”). From September 1939, about 100,000 “Aryan” Germans were assassinated in this manner, in what was named “Operation T4.” Two years later, the personnel responsible for the “euthanasia” program were called upon to apply their expertise to murdering Jews. In the single camp of Chelmno, 150,000 human beings were gassed to death, most of them brought to the camp from annexed territories, the Warthegau district of western Poland and the Lodz Ghetto.
Below are figures for the number of Jews murdered in each country that came under German domination. They are estimates, as are all figures relating to Holocaust victims. The numbers given here for Czechoslovakia, Hungary and Romania are based on their territorial borders before the 1938 Munich agreement. The total number of six million Jews murdered during the Holocaust, which emerged from the Nuremberg trials, is also an estimate. Numbers have ranged between five and seven million killed.
"He grabbed my arm and turned me around," said Freund, now 82. "I was skinny, already. Thank God I didn't have a pimple on my body, because a pimple was all you needed to be sent to the crematorium." (The gas chambers at Auschwitz were located in the crematorium buildings, so that the bodies could be burned immediately after the victims were gassed.)

Despite having provided Mengele with legal documents using his real name in 1956 (which had enabled him to formalize his permanent residency in Argentina), West Germany was now offering a reward for his capture. Continuing newspaper coverage of Mengele's wartime activities, with accompanying photographs, led him to relocate once again in 1960. Former pilot Hans-Ulrich Rudel put him in touch with the Nazi supporter Wolfgang Gerhard, who helped Mengele to cross the border into Brazil.[78][86] He stayed with Gerhard on his farm near São Paulo until more permanent accommodation could be found, with Hungarian expatriates Geza and Gitta Stammer. With the help of an investment from Mengele, the couple bought a farm in Nova Europa, which Mengele was given the job of managing for them. The three bought a coffee and cattle farm in Serra Negra in 1962, with Mengele owning a half interest.[87] Gerhard had initially told the Stammers that Mengele's name was "Peter Hochbichler", but they discovered his true identity in 1963. Gerhard persuaded the couple not to report Mengele's location to the authorities, by convincing them that they themselves could be implicated for harboring the fugitive.[88] In February 1961, West Germany widened its extradition request to include Brazil, having been tipped off to the possibility that Mengele had relocated there.[89]
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.

There is no postwar institution specializing in either World War II or the Holocaust that has collected systematic data about the righteous or about Christian-Jewish relations during the war years. Postwar historiography has given scant attention to this subject, except for biographies of heroes like Raoul Wallenberg in Budapest. Individual episodes are recorded in numerous published memoirs or hidden within the histories of the Jewish communities under German occupation. Others are found in some survivor testimonies, oral histories, and depositions.

Three defendants were acquitted. However, many of the Nazis who perpetrated the Holocaust were never tried or punished, including Hitler who had committed suicide. Since then, the international community has continued and improved accountability through forums such as the International Criminal Court, and the International Criminal Tribunal for Rwanda.
Beginning with the British air raids on Cologne in May of 1942, the Allies launched a strategic bombing campaign that would target cities and industrial plants across the Reich for the next three years. In the summer of 1942, Germany and its allies focused on the Soviet Union unsuccessfully. The Soviet Union gained the dominant role, which it would maintain for the rest of the war.
Romania implemented anti-Jewish measures in May and June 1940 as part of its efforts towards an alliance with Germany. Jews were forced from government service, pogroms were carried out, and by March 1941 all Jews had lost their jobs and had their property confiscated.[169] After Romania joined the invasion of the Soviet Union in June 1941, at least 13,266 Jews were killed in the Iași pogrom,[170] and Romanian troops carried out massacres in Romanian-controlled territory, including the Odessa massacre of 20,000 Jews in Odessa in late 1941. Romania also set up concentration camps under its control in Transnistria, where 154,000–170,000 Jews were deported from 1941 to 1943.[169]
This was more than an exaggerated adolescent flourish. She had already intuited what greatness in literature might mean, and she clearly sensed the force of what lay under her hand in the pages of her diary: a conscious literary record of frightened lives in daily peril; an explosive document aimed directly at the future. In her last months, she was assiduously polishing phrases and editing passages with an eye to postwar publication. Het Achterhuis, as she called her manuscript, in Dutch—“the house behind,” often translated as “the secret annex”—was hardly intended to be Anne Frank’s last word; it was conceived as the forerunner work of a professional woman of letters.
Title bestowed by Yad Vashem (the Israeli Holocaust remembrance authority) on certain gentiles who rescued Jews in opposition to Nazi efforts to annihilate them. The distinction is granted according to stringent criteria requiring conclusive evidence. Depending on the nature and extent of help, special kinds of recognition are bestowed upon Christians who saved Jews. To qualify for any one of the distinctions, Christian actions had to involve “extending help in saving a life; endangering one’s own life; absence of reward, monetary and otherwise; and similar considerations which make the rescuers’ deeds stand out above and beyond what can be termed ordinary help.” In part ambiguous, the criteria leave no doubt that those who saved Jews primarily because of payment do not fit the definition of righteous Christians.
Mengele then moved to experimentation. His work revolved around genetic engineering to eradicate inferior genes from the human population to create a German super-race. He believed that twins held these mysteries, and about 1500 pairs of them were brought to Mengele through the selection process. The twins were provided more comfort than the other prisoners and given extra food rations to keep them healthy. As soon as a pair of twins arrived at Auschwitz, they were tattooed and Mengele would ask them questions about their history. Every morning, they reported for roll call, where they ate a small breakfast. Mengele would then come to talk to them, give them candy, and even play games with some of them. Some of the younger children even called him “Uncle Mengele.” Life wasn’t so bad for twins at the barracks, until it came time for the experiments.
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.
Broadly speaking, the extermination of Jews was carried out in two major operations. With the onset of Operation Barbarossa, launched from occupied Poland in June 1941, mobile killing units of the SS and Orpo were dispatched to Soviet controlled territories of eastern Poland and further into the Soviet republics for the express purpose of killing all Jews, both Polish and Soviet. During the massive chase after the fleeing Red Army, Himmler himself visited Białystok in the beginning of July 1941, and requested that, "as a matter of principle, any Jew" behind the German-Soviet frontier "was to be regarded as a partisan". His new orders gave the SS and police leaders full authority for the mass murder behind the front-lines. By August 1941, all Jewish men, women, and children were shot.[21] In the second phase of annihilation, the Jewish inhabitants of central, western, and south-eastern Europe were transported by Holocaust trains to camps with newly-built gassing facilities. Raul Hilberg wrote: "In essence, the killers of the occupied USSR moved to the victims, whereas outside this arena, the victims were brought to the killers. The two operations constitute an evolution not only chronologically, but also in complexity."[9] Massacres of about one million Jews occurred before plans for the Final Solution were fully implemented in 1942, but it was only with the decision to annihilate the entire Jewish population that extermination camps such as Auschwitz II Birkenau and Treblinka were fitted with permanent gas chambers to kill large numbers of Jews in a relatively short period of time.[22][23]
Meanwhile, Zvi Aharoni, one of the Mossad agents who had been involved in the Eichmann capture, was placed in charge of a team of agents tasked with tracking down Mengele and bringing him to trial in Israel. Their inquiries in Paraguay revealed no clues to his whereabouts, and they were unable to intercept any correspondence between Mengele and his wife Martha, who was then living in Italy. Agents that were following Rudel's movements also failed to produce any leads.[90] Aharoni and his team followed Gerhard to a rural area near São Paulo, where they identified a European man whom they believed to be Mengele.[91] This potential breakthrough was reported to Harel, but the logistics of staging a capture, the budgetary constraints of the search operation, and the priority of focusing on Israel's deteriorating relationship with Egypt led the Mossad chief to call off the hunt for Mengele in 1962.[92]

At the end of the war, Mengele became a fugitive and fled from Auschwitz on January 17, 1945. He spent the next 34 years in hiding. He assumed a fake identity and worked as a farm hand near his native Günzburg until 1949. He fled to Argentina, where he was able to get by unnoticed. The search for Mengele ended in 1985 when West German police raided the home of a lifelong friend of the monster. They seized several letters from Mengele, and within a week, authorities identified the families that had harbored Mengele in South America. They discovered that Mengele had died in a drowning accident in 1979.
Unlike the death camps of Treblinka, Chelmno, Sobibor, and Belzec, which were built and operated solely to kill Jews, the two death camps of Maidanek and Auschwitz also had a work camp attached. Upon arrival at these two camps, a selection was made at the train station concerning which Jews (about 10 percent of the arrivals) would be permitted to live and escape immediate gassing in the gas chambers. These “lucky” survivors were permitted to live only to the extent that they endured the physical and emotional trauma inflicted upon them. They were given a food ration that permitted them to survive for only three months. As they died from exhaustion, beatings, and starvation, they were replaced with newly arrived victims. Auschwitz was also used as the site for medical experimentation. Many of these experiments had little scientific value but were only exercises to discover how much torture a victim could endure until death. By the end of 1944, an estimated two-and-a-half million Jews had died at Auschwitz. More than a quarter of a million Gypsies also died there.
Many Jews were saved by hiding and also by illegal frontier crossings. Anne Frank‘s family hid in the concealed annex of an Amsterdam office building with the help of a Christian friend, and the family of Emmanuel Ringelblum (the Warsaw ghetto historian) hid in Warsaw in a specially prepared underground bunker camouflaged by a Polish gardener’s greenhouse. Both the Franks and the Ringelblums were caught and perished. About 20,000 Polish Jews, however, did survive hidden in Aryan Warsaw. Likewise, 5,000 Dutch Jews and several thousand German Jews were hidden in the heart of the Nazi empire, in Berlin and Hamburg.
American soldiers stare down at a mass grave in Nordhausen concentration camp  © Originally a concentration camp for Polish political prisoners, Auschwitz was greatly expanded in 1941 with the addition of a much larger camp at nearby Birkenau. In all, Auschwitz-Birkenau and its sub-camps held 400,000 registered prisoners including 205,000 Jews, 137,000 Poles, 21,000 Gypsies, 12,000 Soviet POWs and 25,000 others (including a few British POWs). In this largest and worst of all the Nazi concentration camps, 210,000 prisoners died of starvation and abuse.

Belzec, Sobibor, and Treblinka formed part of what the Nazis called “Operation Reinhard,” whose sole purpose was the systematic massacre of Jews. A labor camp existing in Belzec since 1940 was turned into an extermination camp in the autumn of 1941, becoming operative in March 1942. In the same month, the camp at Sobibor was set up to alleviate the overburdened camp of Belzec. The third, Treblinka, received the Jews from Warsaw and the Radom district.
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.
Chiune Sugihara (1 January 1900 – 31 July 1986) was a Japanese diplomat, serving as Vice Consul for the Japanese Empire in Lithuania. During World War II, he helped several thousand Jews leave the country by issuing transit visas to Jewish refugees so that they could travel to Japan. Most of the Jews who escaped were refugees from German-occupied Poland or residents of Lithuania. Sugihara wrote travel visas that facilitated the escape of more than 6,000 Jewish refugees to Japanese territory, risking his career and his family's life.
Anne’s last diary entry was written on August 1, 1944. Three days later the secret annex was discovered by the Gestapo, which had received a tip from Dutch informers. All of the inhabitants were taken into custody. In September the Frank family arrived at Auschwitz, though Anne and Margot were transferred to Bergen-Belsen the following month. In 1945 Anne as well as her mother and sister died.
Hitler targeted the Jews for a specific reason, which was not just racial. The elimination of the Jews had a unique “status” in Hitler’s master plan. While he certainly killed millions of others (gypsies, communists, homosexuals, etc.) he made exceptions for all these groups. The only group for which no exception was made was the Jews—they all had to die.

The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.
The Final Solution (German: Endlösung) or the Final Solution to the Jewish Question (German: die Endlösung der Judenfrage, pronounced [diː ˈɛntˌløːzʊŋ deːɐ̯ ˈjuːdn̩ˌfʁaːɡə]) was a Nazi plan for the genocide of Jews during World War II. The "Final Solution of the Jewish Question" was the official code name for the murder of all Jews within reach, which was not restricted to the European continent.[1] This policy of deliberate and systematic genocide starting across German-occupied Europe was formulated in procedural and geo-political terms by Nazi leadership in January 1942 at the Wannsee Conference held near Berlin,[2] and culminated in the Holocaust, which saw the killing of 90% of Polish Jews,[3] and two thirds of the Jewish population of Europe.[4]
For the most part, these individuals did not plan to become heroes; the names of the rescuers are largely unrecorded, and their good deeds remain anonymous and unrewarded, except in the emotions of those they saved. They helped by providing hiding places, false papers, food, clothing, money, contact with the outside world, underground escape routes and sometimes even weapons.
And so, at the behest of their Führer, a handful of Nazi bureaucrats conspired to bring about the demise of millions. On January 20, 1942, they attended the Wannsee Conference in Berlin, organized by SS-Obergruppenführer Reinhard Heydrich, who told them, “In the course of the practical execution of the Final Solution, Europe will be combed through from west to east.”
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]
“I’ve offered three possibilities” to the museum, Freund said. The first was to try to partially excavate one section of the tunnel and protect it with climate-controlling plexiglass walls. Alternatively, a re-creation could be built, as had been done with the recently finished facsimile of King Tutankhamun’s tomb, in the Valley of the Kings, in Egypt. The last option, Freund allowed, was a “little futuristic”: Relying on the data from the scans, a 3-D film could be created so visitors could relive the experience of the escape.
SS-Obergruppenführer Reinhard Heydrich, head of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb.[256][257] The meeting had been scheduled for 9 December 1941, and invitations had been sent on 29 November, but it had been postponed.[258]

On July 5, 1942, Anne's older sister Margot received an official summons to report to a Nazi work camp in Germany, and on July 6, Margot and Anne went into hiding with their father Otto and mother Edith. They were joined by Hermann van Pels, Otto's business partner, including his wife Auguste and their teenage son Peter.[12] Their hiding place was in the sealed-off upper rooms of the annex at the back of Otto's company building in Amsterdam.[12][13] Otto Frank started his business, named Opekta, in 1933. He was licensed to manufacture and sell pectin, a substance used to make jam. He stopped running his business while everybody was in hiding. But once he returned, he found his employees running it. The rooms that everyone hid in were concealed behind a movable bookcase in the same building as Opekta. Mrs. van Pels's dentist, Fritz Pfeffer, joined them four months later. In the published version, names were changed: The van Pelses are known as the Van Daans, and Fritz Pfeffer as Albert Dussel. With the assistance of a group of Otto Frank's trusted colleagues, they remained hidden for two years and one month.
Before the the Final Solution the plan the Nazis had was to force the Jews to immigration. In 1940 the nazis planed to ship the Jews to an Island in the Indian ocean called Madagascar. it was not until later they referred to the Final Solution as genocide rather than territorial Final Solution. As the nazis were under cover of the war they developed technology to successfully murder millions of Jews. details were worked out at the Wansee Conference. All Jews in Germanys occupied countries were sent to ghettos as holding areas. Many were sent to camps were they worked under brutal conditions. Many were sent to gas chambers. As the Allies advanced death marches cut down the number of potential survivors. Some of Hitler's objectives were to wage to wars at once one aimed at anyone who objected him the other at the Jews. Hitler's success was credited to planed steps and reaction to those of other world powers. 

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.
When the Nazi’s rose to power they built facilities to hold and, eventually kill, their enemies. When the first concentration camps were built in 1933, this primarily meant political dissidents and opponents of the Nazi government, such as German Communists, Socialists, Social Democrats but would grow to include asocial groups – Gypsies, Jehovah’s Witnesses, the homeless, the mentally ill and homosexuals.  It was not until Kristallnacht that the prisoners became primarily Jewish.
There were setbacks. In March, the diggers discovered they were tunneling in the direction of a burial pit and were forced to reroute the passageway, losing days in the process. Not long afterward, Dogim was on burial pit duty when he unearthed the bodies of his wife, mother and two sisters. Every member of the Burning Brigade lived with the knowledge that some of the corpses he was helping to burn belonged to family members. And yet to see one’s wife lying in the pit was something else entirely, and Dogim was consumed with sadness and fury. “[He] said he had a knife, that he was going to stab and kill the Sturmbannführer,” Farber later recalled. Farber told Dogim that he was thinking selfishly—even if he succeeded, the rest of the prisoners would be killed in retribution.
Germany implemented the persecution of the Jews in stages. Following Adolf Hitler's appointment as German Chancellor in January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933.[5] After the passing of the Enabling Act on 24 March,[6] which gave Hitler plenary powers, the government began isolating Jews from civil society, which included a boycott of Jewish businesses in April 1933 and enacting the Nuremberg Laws in September 1935. On 9–10 November 1938, during Kristallnacht (the "Night of Broken Glass"), Jewish businesses and other buildings were ransacked, smashed or set on fire throughout Germany and Austria, which Germany had annexed in March that year. After Germany invaded Poland in September 1939, triggering World War II, the regime set up ghettos to segregate Jews. Eventually thousands of camps and other detention sites were established across German-occupied Europe.

Friday, August 1, marks the 70th anniversary of Anne Frank's final diary entry. Three days later, she was arrested with her family in the "secret annex" of a house in Amsterdam, Netherlands, where they had hidden for two years. She later died at the Bergen-Belsen concentration camp when she was 15. In her diary, Anne describes a 1942 picture of herself: "This is a photo as I would wish myself to look all the time. Then I would maybe have a chance to come to Hollywood." Click through the gallery to see other pages from her diary:

The worst example was the pogrom in the town of Kielce in Poland on July 4th, 1946. When the 200 surviving Jews returned to their village, the local Poles who were upset to see that any had survived instigated a blood libel—accusing the Jews of the kidnap and ritual murder of Polish child. In the ensuing violence 40 of the Jews, all Holocaust survivors, were murdered by the Polish towns people.
Nevertheless, some acts of rescue seem to have been unplanned, spontaneous extensions of a general habit to help the needy. Indeed, most rescuers do not appear to have thought carefully about their actions or analyzed them; instead, they viewed their assistance to Jews as a natural reaction to human suffering. Some even insisted in postwar interviews that there was nothing special about what they did to save Jewish lives. Only a small fraction of rescuers saw their saving of Jews as extraordinary. A large majority of rescuers described aiding Jews because they were in pain and in need, while just over one-quarter said that they helped because it was a Christian duty. About half saw their actions as a protest against the occupation. For some rescuers, such attitudes required protecting even people they disliked.

Cesarani notes that by 1943, as the military position of the German forces deteriorated, the Nazi leadership became more openly explicit about the Final Solution. In March, Goebbels confided to his diary: "On the Jewish question especially, we are in it so deeply that there is no getting out any longer. And that is a good thing. Experience teaches that a movement and a people who have burned their bridges fight with much greater determination and fewer constraints than those that have a chance of retreat."[127]
When Hitler and his Nazis built the Warsaw Ghetto and herded 500,000 Polish Jews behind its walls to await liquidation, many Polish gentiles turned their backs or applauded. Not Irena Sendler. An unfamiliar name to most people, but this remarkable woman defied the Nazis and saved 2,500 Jewish children by smuggling them out of the Warsaw Ghetto. As a health worker, she sneaked the children out between 1942 and 1943 to safe hiding places and found non-Jewish families to adopt them.
The Nazis brought their own strain of radical ruthlessness to these ideas. They glorified war and saw the uncompromising struggle for survival between nations and races as the engine of human progress. They rejected morality as a Jewish idea, which had corrupted and weakened the German people. They maintained that a great nation such as Germany had the right and duty to build an empire based on the subjugation of 'inferior races'. They looked eastwards to Poland and Russia (where, as it happened, the great majority of European Jews lived) for the territorial expansion of their 'living space' (Lebensraum).
The Chelmno killing center begins operation. The Nazis later establish five other such camps: Belzec, Sobibor, Treblinka, Auschwitz-Birkenau (part of the Auschwitz complex), and Majdanek. Victims at Chelmno are killed in gas vans (hermetically sealed trucks with engine exhaust diverted to the interior compartments). The Belzec, Sobibor, and Treblinka camps use carbon monoxide gas generated by stationary engines attached to gas chambers. Auschwitz-Birkenau, the largest of the killing centers, has four large gas chambers using Zyklon B (crystalline hydrogen cyanide) as the killing agent. The gas chambers at Majdanek use both carbon monoxide and Zyklon B. Millions of Jews are killed in the gas chambers in the killing centers as part of the "Final Solution."
In the eyes of the world, we’re doomed, but if after all this suffering, there are still Jews left, the Jewish people will be held up as an example. Who knows, maybe our religion will teach the world and all the people in it about goodness, and that’s the reason, the only reason, we have to suffer. . . . God has never deserted our people. Through the ages Jews have had to suffer, but through the ages they’ve gone on living, and the centuries of suffering have only made them stronger.
There has been much conjecture about the identity or inspiration of Kitty, who in Anne's revised manuscript is the sole recipient of her letters. In 1996, the critic Sietse van der Hoek wrote that the name referred to Kitty Egyedi, a prewar friend of Anne's. Van der Hoek may have been informed by the publication A Tribute to Anne Frank (1970), prepared by the Anne Frank Foundation, which assumed a factual basis for the character in its preface by the then-chairman of the Foundation, Henri van Praag, and accentuated this with the inclusion of a group photograph that singles out Anne, Sanne Ledermann, Hanneli Goslar, and Kitty Egyedi. Anne does not mention Kitty Egyedi in any of her writings (in fact, the only other girl mentioned in her diary from the often reproduced photo, other than Goslar and Ledermann, is Mary Bos, whose drawings Anne dreamed about in 1944) and the only comparable example of Anne's writing unposted letters to a real friend are two farewell letters to Jacqueline van Maarsen, from September 1942.[20]
The twins were then tattooed and given a number from a special sequence. They were then taken to the twins' barracks where they were required to fill out a form. The form asked for a brief history and basic measurements such as age and height. Many of the twins were too young to fill the form out by themselves so the Zwillingsvater (twin's father) helped them. (This inmate was assigned to the job of taking care of the male twins.)

Twins were subjected to weekly examinations and measurements of their physical attributes by Mengele or one of his assistants.[49] The experiments he performed on twins included unnecessary amputation of limbs, intentionally infecting one twin with typhus or some other disease, and transfusing the blood of one twin into the other. Many of the victims died while undergoing these procedures,[50] and those who survived the experiments were sometimes killed and their bodies dissected once Mengele had no further use for them.[51] Nyiszli recalled one occasion on which Mengele personally killed fourteen twins in one night by injecting their hearts with chloroform.[31] If one twin died from disease, he would kill the other twin to allow comparative post-mortem reports to be produced for research purposes.[52]
