The entry of the U.S. into the War is also crucial to the time-frame proposed by Christian Gerlach, who argued in his 1997 thesis,[122] that the Final Solution decision was announced on 12 December 1941, when Hitler addressed a meeting of the Nazi Party (the Reichsleiter) and of regional party leaders (the Gauleiter).[123][a] The day after Hitler's speech, on 13 December 1941 Joseph Goebbels wrote in his diary:[125]

Like most “scientists” at work in the concentration camp environment, Mengele enlisted the aid of trained medical professionals among the prisoner population to perform the more grisly, or mundane, tasks and to carry out autopsies upon his dead victims. Much of our early knowledge of Mengele's activities at Auschwitz comes from Dr. Miklos Nyiszli, a prisoner-physician who assisted Mengele under duress. Nyiszli published his experiences, initially in his native Hungarian, in 1946. His work Auschwitz: A Doctor's Eyewitness Account appeared in English in 1960.
If only Anne Frank's diary was the figment of someone's imagination. If it meant that this spirited, intelligent and articulate girl hadn't died along with so many others in Belsen concentration camp, and that the holocaust had never happened, that would be a wonderful thing, but it did happen, and that makes the reading of this diary even more heartbreaking.
In the early part of 1939, my father, mother and infant brother were living in Paris, as refugees from the pogroms in Romania. They were illegal immigrants, living modestly with the hope of giving themselves and their son a better future than the one they had. But World War II was approaching, and the citizens of France were in danger of falling prey to the Vichy regime that was collaborating with Germany and Hitler. As Jews and illegal residents, my parents were in an extremely precarious situation. They were poor and had no connections or reasonable way of changing their situation. But a gentile, the wife of an Italian diplomat for whom my mother sewed her clothes, understood what the future of my family would be if they stayed in France. In an act of righteousness, mercy and generosity, she offered my parents tickets: first for the train to Marseilles and then, passage onto a ship bound to Bolivia. I was born in Bolivia, where my family’s life was spared the horrors of the Holocaust. I have eternal gratitude to the woman who saved us.
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.
Browning believes that the "Final Solution as it is now understood—the systematic attempt to murder every last Jew within the German grasp"[5] took shape during a five-week period, from 18 September to 25 October 1941. During this time: the sites of the first extermination camps were selected, different methods of killing were tested, Jewish emigration from the Third Reich was forbidden, and 11 transports departed for Łódź as a temporary holding station. During this period, Browning writes, "The vision of the Final Solution had crystallised in the minds of the Nazi leadership, and was being turned into reality."[5] This period was the peak of Nazi victories against the Soviet Army on the Eastern Front, and, according to Browning, the stunning series of German victories led to both an expectation that the war would soon be won, and the planning of the final destruction of the "Jewish-Bolshevik enemy".[114]
Himmler ordered the closure of ghettos in Poland in mid-July 1942; most inhabitants were sent to extermination camps. Those Jews needed for war production would be confined in concentration camps.[220] The deportations from the Warsaw Ghetto began on 22 July; over the almost two months of the Aktion, until 12 September, the population was reduced from 350,000 to 65,000. Those deported were transported in freight trains to the Treblinka extermination camp.[221] Similar deportations happened in other ghettos, with many ghettos totally emptied.[222] The first ghetto uprisings occurred in mid-1942 in small community ghettos.[223] Although there were armed resistance attempts in both the larger and smaller ghettos in 1943, in every case they failed against the overwhelming German military force, and the remaining Jews were either killed or deported to the death camps.[224]
The nature and timing of the decisions that led to the Final Solution is an intensely researched and debated aspect of the Holocaust. The program evolved during the first 25 months of war leading to the attempt at "murdering every last Jew in the German grasp".[5] Most historians agree, wrote Christopher Browning, that the Final Solution cannot be attributed to a single decision made at one particular point in time.[5] "It is generally accepted the decision-making process was prolonged and incremental."[6] In 1940, following the Fall of France, Adolf Eichmann devised the Madagascar Plan to move Europe's Jewish population to the French colony, but the plan was abandoned for logistical reasons, mainly a naval blockade.[7] There were also preliminary plans to deport Jews to Palestine and Siberia.[8] In 1941, wrote Raul Hilberg, in the first phase of the mass murder of Jews, the mobile killing units began to pursue their victims across occupied eastern territories; in the second phase, stretching across all of German-occupied Europe, the Jewish victims were sent on death trains to centralized extermination camps built for the purpose of systematic implementation of the Final Solution.[9]
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.
Timothy Snyder writes that Longerich "grants the significance of Greiser's murder of Jews by gas at Chełmno in December 1941", but also detects a significant moment of escalation in spring 1942, which includes "the construction of the large death factory at Treblinka for the destruction of the Warsaw Jews, and the addition of a gas chamber to the concentration camp at Auschwitz for the murder of the Jews of Silesia".[117] Longerich suggests that it "was only in the summer of 1942, that mass killing was finally understood as the realization of the Final Solution, rather than as an extensively violent preliminary to some later program of slave labor and deportation to the lands of a conquered USSR". For Longerich, to see mass killing as the Final Solution was an acknowledgement by the Nazi leadership that there would not be a German military victory over the USSR in the near future.[117]
Over the next two years, Anne wrote faithfully in the diary, which she came to consider a friend, addressing many of the entries to “Dear Kitty.” In the journal and later notebooks, Anne recounted the day-to-day life within the annex. The close quarters and sparse supplies led to various arguments among the inhabitants, and the outgoing Anne came to find the conditions stifling. Heightening tensions was the ever-present concern that they would be discovered. However, many entries involve typical adolescent issues—jealousy toward her sister; annoyance with others, especially her mother; and an increasing sexual awareness. Anne wrote candidly about her developing body, and she experienced a brief romance with Peter van Pels. She also discussed her hopes for the future, which included becoming a journalist or a writer. In addition to the diary, Anne penned several short stories and compiled a list of “beautiful sentences” from other works.
Every day, twins were selected for experimentation. He would require that they give blood and sometimes so much was drawn that a twin would faint. Some underwent huge blood transfusions from one twin to the other. In an attempt to change their eye color, he painfully injected chemicals into their eyes, only to result in infection. One night he collected 7 sets of twins with different colored eyes, killed them, dissected them, and then sent the eyes to von Verschuer for analysis. Twins as young as 5 were killed from experiments, then their bodies dissected. For one pair of twins, he attempted to create conjoined twins by sewing their backs together and trying to connect blood vessels and organs. A few days after the extremely painful process, the twins developed gangrene and died. Many twins had their limbs and organs removed without the use of an anesthetic. Other experiments included isolation endurance, reactions to various stimuli, spinal taps without anesthesia, the removal of sexual organs, and incestuous impregnations. Out of the 1500 twins experimented on by Mengele, only around 200 survived the horror.
During the Nazi occupation of the Netherlands, Anne Frank received a blank diary as one of her presents on June 12, 1942, her 13th birthday.[8][9] According to the Anne Frank House, the red, checkered autograph book which Anne used as her diary was actually not a surprise, since she had chosen it the day before with her father when browsing a bookstore near her home.[9] She began to write in it on June 14, 1942, two days later.[10][11]
Throughout the late-1930s, the Nazi government began to forcibly acquire ethnically German territory in Austria and Czechoslovakia that was taken from Germany at the end of the First World War. Although the international community initially allowed Germany to incorporate these territories into the growing German Empire, it became increasingly clear that Hitler’s ambition did not stop at these small territories. When Germany invaded Poland on September 1, 1939, Britain and France responded by declaring war on Germany, beginning the Second World War.

But Soviet forces were hurtling toward Auschwitz, and in November the order went out to conceal all evidences of gassing and to blow up the crematoria. Tens of thousands of inmates, debilitated and already near extinction, were driven out in bitter cold on death marches. Many were shot. In an evacuation that occurred either on October 28th or on November 2nd, Anne and Margot were dispatched to Bergen-Belsen. Margot was the first to succumb. A survivor recalled that she fell dead to the ground from the wooden slab on which she lay, eaten by lice, and that Anne, heartbroken and skeletal, naked under a bit of rag, died a day or two later.

SS Officer Hosler, under arrest, stands in front of a truck which is loaded with corpses at Belsen concentration camp  © The Final Solution moved into its last stages as Allied forces began to close in on Germany in 1944. The Project Reinhardt camps were razed. A prisoner work-gang called the Blobel Commando began digging up and burning the bodies of those killed by the Einsatzgruppen. Prisoners remaining in Auschwitz and other concentration camps were transported or force-marched to camps within Germany. Hardly fit for such an effort, thousands of prisoners on these death marches succumbed to starvation, exhaustion and cold, or were shot for not keeping up the pace.
From this moment on, the Nazi regime adopted hundreds of laws restricting the rights and liberties of the Jewish people. Jews were expelled from the civil service and barred from entering particular professions, stripped of their citizenship, and forbidden from intermarrying or even having a relationship with anyone of “German or German-related blood”.
It may be, though, that a new production, even now, and even with cautious additions, will be heard in the play’s original voice. It was always a voice of good will; it meant, as we say, well—and, financially, it certainly did well. But it was Broadway’s style of good will, and that, at least for Meyer Levin, had the scent of ill. For him, and signally for Bloomgarden and Kanin, the most sensitive point—the focus of trouble—lay in the ancient dispute between the particular and the universal. All that was a distraction from the heart of the matter: in a drama about hiding, evil was hidden. And if the play remains essentially as the Hacketts wrote it, the likelihood is that Anne Frank’s real history will hardly prevail over what was experienced, forty years ago, as history transcended, ennobled, rarefied. The first hint is already in the air, puffed by the play’s young lead: It’s funny, it’s hopeful, and she’s a happy person.
 In October 1942, Jan Karski met clandestinely with Jewish leaders at the height of the destruction of Polish Jewry. As a courier for the underground, he delivered their dire message to the Polish government-in-exile in London. “The Jews were abandoned by governments, by church hierarchies, by existing societal structures. But they were not abandoned by all of humanity,” said Karski. “There were thousands upon thousands of people in Europe who risked their life for the Jews. They were priests, nuns, workers, peasants, enlightened ones, simpletons, from all walks of life. They were good people, very simply. We have more good people than probably we think we have in humanity.” Karski was recognized by Yad Vashem as a Righteous Gentile among the Gentiles on June 2, 1982
A victim of Nazi medical experimentation. A victim's arm shows a deep burn from phosphorus at Ravensbrueck, Germany, in November of 1943. The photograph shows the results of a medical experiment dealing with phosphorous that was carried out by doctors at Ravensbrueck. In the experiment, a mixture of phosphorus and rubber was applied to the skin and ignited. After twenty seconds, the fire was extinguished with water. After three days, the burn was treated with Echinacin in liquid form. After two weeks the wound had healed. This photograph, taken by a camp physician, was entered as evidence during the Doctors Trial at Nuremberg. #
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.

Rooted in 19th-century antisemitic discourse on the "Jewish question," "Final Solution" as a Nazi cover term denotes the last stage in the evolution of the Third Reich's anti-Jewish policies from persecution to physical annihilation on a European scale. Currently, Final Solution is used interchangeably with other, broader terms that refer to German extermination policies during World War II, as well as more specifically to describe German intent and the decision-making process leading up to the beginning of systematic mass murder.

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.
3. On 25th December 1943, I was sick with typhus and was picked out at a selection made by doctors Mengele and Tauber along with about 350 other women. I was made to undress and taken by lorry to a gas chamber. There were seven gas chambers at Auschwitz. This particular one was underground and the lorry was able to run down the slope and straight into the chamber.
Often, reading Anne Frank's diary is the way in which young people first learn about the horrors of the Nazi genocide. Just as importantly, young readers understand that these crimes were visited upon a girl much like themselves and their friends -- a girl who was often in conflict with her mother, a girl who kept vowing to be a more patient and forgiving person, a girl who fell in love for the first time. A girl who wanted to be a writer -- and who was one.
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]
It was reported around the world that in February 2014, 265 copies of the Frank diary and other material related to the Holocaust were found to be vandalized in 31 public libraries in Tokyo, Japan.[40][41] The Simon Wiesenthal Center expressed "its shock and deep concern"[42] and, in response, Chief Cabinet Secretary Yoshihide Suga called the vandalism "shameful." Israel donated 300 copies of Anne Frank's diary to replace the vandalized copies.[43] An anonymous donor under the name of 'Chiune Sugihara' donated two boxes of books pertaining to the Holocaust to the Tokyo central library.[44] After media attention had subsided, police arrested an unemployed man in March.[45] In June, prosecutors decided not to indict the suspect after he was found to be mentally incompetent.[46] Tokyo librarians have reported that Nazi-related books such as the diary and Man's Search for Meaning attract people with mental disorder and are subject to occasional vandalism.[47][better source needed]
Another survivor of Auschwitz-Birkenau was Regina Bialek, a Polish political prisoner, who was saved from the gas chamber at the last moment by Dr. Josef Mengele. Bialek gave a deposition which was entered into the British Trial of Josef Kramer and Forty-Four Others, also known as The Belsen Trial, which took place in 1945 after the end of World War II. According to Bialek's testimony, the gassing of the Jews at Birkenau did not stop, even on Christmas day.

Albert Goering loathed all of Nazism's inhumanity and at the risk of his career, fortune and life, used his name and connections to save hundreds of Jews and and political dissidents during the Second World War. After the war Albert Goering - savior of victims of the tyranny his brother helped create - was imprisoned for several years for his name alone. But his story is almost unknown: he was shoved into obscurity by the enormity of his brother's crimes.
By mid-1944 those Jewish communities within easy reach of the Nazi regime had been largely exterminated,[367] in proportions ranging from about 25 percent in France[368] to more than 90 percent in Poland.[369] On 5 May Himmler claimed in a speech that "the Jewish question has in general been solved in Germany and in the countries occupied by Germany".[370] As the Soviet armed forces advanced, the camps in eastern Poland were closed down, with surviving inmates shipped to camps closer to Germany.[371] Efforts were made to conceal evidence of what had happened. The gas chambers were dismantled, the crematoria dynamited, and the mass graves dug up and the corpses cremated.[372] Local commanders continued to kill Jews, and to shuttle them from camp to camp by forced "death marches".[373] Already sick after months or years of violence and starvation, some were marched to train stations and transported for days at a time without food or shelter in open freight cars, then forced to march again at the other end to the new camp. Others were marched the entire distance to the new camp. Those who lagged behind or fell were shot. Around 250,000 Jews died during these marches.[374]
Anxious to limit immigration to the United States and to maintain good relations with the Vichy government, the State Department actively discouraged diplomats from helping refugees. However, Bingham cooperated in issuing visas and helping refugees escape France. Hiram Bingham gave about 2,000 visas, most of them to well-known personalities, speaking English, including Max Ernst, André Breton, Hannah Arendt, Marc Chagall, Lion Feuchtwanger and Nobel prize winner Otto Meyerhof.
After obtaining a copy of his birth certificate through the West German embassy in 1956, Mengele was issued with an Argentine foreign residence permit under his real name. He used this document to obtain a West German passport, also using his real name, and embarked on a trip to Europe.[71][72] He met up with his son Rolf (who was told Mengele was his "Uncle Fritz")[73] and his widowed sister-in-law Martha, for a ski holiday in Switzerland; he also spent a week in his home town of Günzburg.[74][75] When he returned to Argentina in September 1956, Mengele began living under his real name. Martha and her son Karl Heinz followed about a month later, and the three began living together. Josef and Martha were married in 1958 while on holiday in Uruguay, and they bought a house in Buenos Aires.[71][76] Mengele's business interests now included part ownership of Fadro Farm, a pharmaceutical company.[74] Along with several other doctors, Mengele was questioned in 1958 on suspicion of practicing medicine without a license when a teenage girl died after an abortion, but he was released without charge. Aware that the publicity would lead to his Nazi background and wartime activities being discovered, he took an extended business trip to Paraguay and was granted citizenship there in 1959 under the name "José Mengele".[77] He returned to Buenos Aires several times to settle his business affairs and visit his family. Martha and Karl lived in a boarding house in the city until December 1960, when they returned to Germany.[78]
