Peter Longerich argues that the search for a finite date on which the Nazis embarked upon the extermination of the Jews is futile, in his book Holocaust: The Nazi Persecution and Murder of the Jews (2011). Longerich writes: "We should abandon the notion that it is historically meaningful to try to filter the wealth of available historical material and pick out a single decision" that led to the Holocaust.[116][117]
In the summer of 1941, Rudolf Höss, the commandant of Auschwitz, received orders from Heinrich Himmler to begin experimenting with Zyklon B gas. On 3 September 1941, the Auschwitz deputy camp commandant Karl Fritzsch experimented on 600 Russian prisoners of war and 250 Polish inmates by gathering them in the basement of Block 11 and gassing them with Zyklon B.
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.
Under the rule of Adolf Hitler, the persecution and segregation of Jews was implemented in stages. After the Nazi Party achieved power in Germany in 1933, its state-sponsored racism led to anti-Jewish legislation, economic boycotts, and the violence of the Kristallnacht ("Night of Broken Glass") pogroms, all of which aimed to systematically isolate Jews from society and drive them out of the country.

Born on March 16, 1911 in Günzburg, Germany to a prosperous family, Josef Mengele was the eldest of 3 children. In 1935, he earned a PhD in physical anthropology from the University of Munich, and 2 years later he became the assistant of Dr. Otmar von Verschuer, a leading scientific figure known for his research with twins, at the Institute for Hereditary Biology and Racial Hygiene in Frankfurt. That same year, Mengele joined the Nazi Party, and in 1938, joined the SS. In 1940, he was drafted into the military, where he volunteered for medical service in the Waffen-SS. However, his time in the military was cut short after being wounded while on campaign and he was sent back to Germany, where he resumed work with von Verschuer at the Kaiser Wilhelm Institute for Anthropology.
Because of this book, we will remember the names, the quirks -- the characters -- of the eight people who inhabited the secret annex and their brave Dutch helpers. We will be able to visualize them long after everyone who witnessed that horrific era is gone. It is because of Anne's diary that she and her family are among the few we will remember -- the ones we feel we know -- among the millions who suffered and died as she did.
The Netherlands Institute for War Documentation commissioned a forensic study of the manuscripts after the death of Otto Frank in 1980. The material composition of the original notebooks and ink, and the handwriting found within them and the loose version were extensively examined. In 1986, the results were published: The handwriting attributed to Anne Frank was positively matched with contemporary samples of Anne Frank's handwriting, and the paper, ink, and glue found in the diaries and loose papers were consistent with materials available in Amsterdam during the period in which the diary was written.[56]
“With respect of the Jewish Question, the Führer has decided to make a clean sweep. He prophesied to the Jews that if they again brought about a world war, they would live to see their annihilation in it. That wasn’t just a catchword… If the German people have now again sacrificed 160,000 dead on the eastern front, then those responsible for this bloody conflict will have to pay with their lives.”
Timothy D. Snyder (Bloodlands: Europe Between Hitler and Stalin, 2010): "In this book the term Holocaust signifies the final version of the Final Solution, the German policy to eliminate the Jews of Europe by murdering them. Although Hitler certainly wished to remove the Jews from Europe in a Final Solution earlier, the Holocaust on this definition begins in summer 1941, with the shooting of Jewish women and children in the occupied Soviet Union. The term Holocaust is sometimes used in two other ways: to mean all German killing policies during the war, or to mean all oppression of Jews by the Nazi regime. In this book, Holocaust means the murder of the Jews in Europe, as carried out by the Germans by guns and gas between 1941 and 1945."[23]

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.”

"... Believe me, I'd like to listen, but it doesn't work, because if I'm quiet and serious, everyone thinks I'm putting on a new act and I have to save myself with a joke, and then I'm not even talking about my own family, who assume I must be ill, stuff me with aspirins and sedatives, feel my neck and forehead to see if I have a temperature, ask about my bowel movements and berate me for being in a bad mood, until I just can't keep it up any more, because when everybody starts hovering over me, I get cross, then sad, and finally end up turning my heart inside out, the bad part on the outside and the good part on the inside, and keep trying to find a way to become what I'd like to be and what I could be if ... if only there were no other people in the world."
The “real contents” had already been altered by Frank himself, and understandably, given the propriety of his own background and of the times. The diary contained, here and there, intimate adolescent musings, talk of how contraceptives work, and explicit anatomical description: “In the upper part, between the outer labia, there’s a fold of skin that, on second thought, looks like a kind of blister. That’s the clitoris. Then come the inner labia . . .” All this Frank edited out. He also omitted passages recording his daughter’s angry resistance to the nervous fussiness of her mother (“the most rotten person in the world”). Undoubtedly he better understood Edith Frank’s protective tremors, and was unwilling to perpetuate a negative portrait. Beyond this, he deleted numerous expressions of religious faith, a direct reference to Yom Kippur, terrified reports of Germans seizing Jews in Amsterdam. It was prudence, prudishness, and perhaps his own deracinated temperament that stimulated many of these tamperings. In 1991, eleven years after Frank’s death, a “definitive edition” of the diary restored everything he had expurgated. But the image of Anne Frank as merry innocent and steadfast idealist—an image the play vividly promoted—was by then ineradicable.
Beginning in late 1941, the Germans began mass transports from the ghettoes in Poland to the concentration camps, starting with those people viewed as the least useful: the sick, old and weak and the very young. The first mass gassings began at the camp of Belzec, near Lublin, on March 17, 1942. Five more mass killing centers were built at camps in occupied Poland, including Chelmno, Sobibor, Treblinka, Majdanek and the largest of all, Auschwitz-Birkenau. From 1942 to 1945, Jews were deported to the camps from all over Europe, including German-controlled territory as well as those countries allied with Germany. The heaviest deportations took place during the summer and fall of 1942, when more than 300,000 people were deported from the Warsaw ghetto alone.
Over the decades that followed, ordinary Germans struggled with the Holocaust’s bitter legacy, as survivors and the families of victims sought restitution of wealth and property confiscated during the Nazi years. Beginning in 1953, the German government made payments to individual Jews and to the Jewish people as a way of acknowledging the German people’s responsibility for the crimes committed in their name.
After 1942, the economic functions of the camps, previously secondary to their penal and terror functions, came to the fore. Forced labor of camp prisoners became commonplace.[182] The guards became much more brutal, and the death rate increased as the guards not only beat and starved prisoners, but killed them more frequently.[186] Vernichtung durch Arbeit ("extermination through labor") was a policy—camp inmates would literally be worked to death, or to physical exhaustion, at which point they would be gassed or shot.[187] The Germans estimated the average prisoner's lifespan in a concentration camp at three months, due to lack of food and clothing, constant epidemics, and frequent punishments for the most minor transgressions.[188] The shifts were long and often involved exposure to dangerous materials.[189]
In nearly every country overrun by the Nazis, the Jews were forced to wear badges marking them as Jews, they were rounded up into ghettos or concentration camps and then gradually transported to the killing centers. The death camps were essentially factories for murdering Jews. The Germans shipped thousands of Jews to them each day. Within a few hours of their arrival, the Jews had been stripped of their possessions and valuables, gassed to death, and their bodies burned in specially designed crematoriums. Approximately 3.5 million Jews were murdered in these death camps.
In the 1960s, Otto Frank recalled his feelings when reading the diary for the first time, "For me, it was a revelation. There, was revealed a completely different Anne to the child that I had lost. I had no idea of the depths of her thoughts and feelings."[23] Michael Berenbaum, former director of the United States Holocaust Memorial Museum, wrote, "Precocious in style and insight, it traces her emotional growth amid adversity. In it, she wrote, 'In spite of everything, I still believe that people are really good at heart.'"[23]
Medical experiments conducted on camp inmates by the SS were another distinctive feature.[51] At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later.[52] Twenty-three senior physicians and other medical personnel were charged at Nuremberg, after the war, with crimes against humanity. They included the head of the German Red Cross, tenured professors, clinic directors, and biomedical researchers.[53] Experiments took place at Auschwitz, Buchenwald, Dachau, Natzweiler-Struthof, Neuengamme, Ravensbrück, Sachsenhausen, and elsewhere. Some dealt with sterilization of men and women, the treatment of war wounds, ways to counteract chemical weapons, research into new vaccines and drugs, and the survival of harsh conditions.[52]

On June 29, the Times of Israel reported on the discovery: “New tech reveals forgotten Holocaust escape tunnel in Lithuania.” News media around the world picked up the story, including the BBC and the New York Times. To Freund, finding the tunnel finally made it possible to fully comprehend the perseverance the escapees had demonstrated. “What people were so captivated by, I think, was that this was a tale of hope,” he told me. “It proved how resilient humans can be.”

Hitler also believed the very presence of Jews in Germany and Nazi-occupied Europe posed a threat to German victory in the war. This was based on his experience during the First World War, when Germany had experienced a meltdown of civilian morale. In 1916, as a young soldier on sick leave in Munich, Hitler had been appalled at the apathy and anti-war sentiment he witnessed among German civilians. At the time, he concluded disloyal Jews had banded together and conspired to undermine the German war effort. And he was convinced they would do it again now if given the chance.

In April 1944, two Jewish inmates escaped from Auschwitz and made it safely into Czechoslovakia. One of them, Rudolf Vrba, submitted a detailed report to the Papal Nuncio in Slovakia which was then forwarded to the Vatican, received there in mid-June. Thus far, Pope Pius XII had not issued a public condemnation of Nazi maltreatment and subsequent mass murder of Jews, and he chose to continue his silence.
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]
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.
Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.

The diary is not written in the classic forms of "Dear Diary" or as letters to oneself; Anne calls her diary "Kitty", so almost all of the letters are written to Kitty. Anne used the above-mentioned names for her annex-mates in the first volume, from September 25, 1942 until November 13, 1942, when the first notebook ends.[18] It is believed that these names were taken from characters found in a series of popular Dutch books written by Cissy van Marxveldt.[18]
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]
