The murderous events in the occupied Soviet Union had – as envisaged in a directive by Alfred Rosenberg's Reich Ministry for the Occupied Eastern Territories – provided the German leadership with experiences on how to arrive at a "solution to the overall problem" ("für die Loesung des Gesamt-Problems richtungsweisend") that could be applied elsewhere. On July 31, 1941, Goering signed a document that charged Heydrich with "making all necessary preparations with regard to organizational, practical and material aspects for an overall solution ("Gesamtloesung") of the Jewish question in the German sphere of influence in Europe" and to draw up a plan "for the implementation of the intended final solution ("Endloesung") of the Jewish question." By the time of the Wannsee Conference held on January 20, 1942, the term Final Solution had become a common phrase among German government and party officials. Now reduced in its actual meaning to mass murder, its geographical scope expanded beyond German-dominated Europe: the protocol of the conference listed 11 million Jews in different countries to be engulfed in the "Final Solution of the European Jewish question," including England and neutrals like Sweden and Switzerland. The culmination of the Final Solution in mass deportations from various parts of Europe to the killing centers and death camps in Eastern Europe resulted, like earlier stages of the process, not from one single top-level decision, but from a complex mix of factors, with the Berlin center reacting as much as it was actively shaping events.
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.)

On 19 October 1943, five days after the prisoner revolt in Sobibór, Operation Reinhard was terminated by Odilo Globocnik on behalf of Himmler. The camps responsible for the killing of nearly 2,700,000 Jews were soon closed. Bełżec, Sobibór, and Treblinka were dismantled and ploughed over before spring.[94] The operation was followed by the single largest German massacre of Jews in the entire war carried out on 3 November 1943; with approximately 43,000 prisoners shot one-by-one simultaneously in three nearby locations by the Reserve Police Battalion 101 hand-in-hand with the Trawniki men from Ukraine.[95] Auschwitz alone had enough capacity to fulfill the Nazis' remaining extermination needs.[79]
First published under the title Het Achterhuis. Dagboekbrieven 14 Juni 1942 – 1 Augustus 1944 (The Annex: Diary Notes 14 June 1942 – 1 August 1944) by Contact Publishing in Amsterdam in 1947, the diary received widespread critical and popular attention on the appearance of its English language translation Anne Frank: The Diary of a Young Girl by Doubleday & Company (United States) and Vallentine Mitchell (United Kingdom) in 1952. Its popularity inspired the 1955 play The Diary of Anne Frank by the screenwriters Frances Goodrich and Albert Hackett, which they adapted for the screen for the 1959 movie version. The book is included in several lists of the top books of the 20th century.[1][2][3][4][5][6]
Overnight on November 9-10, 1938, the Nazis incited a pogrom against Jews in Austria and Germany called Kristallnacht (Night of Broken Glass, or literally translated from German, "Crystal Night"). This included the pillaging and burning of synagogues, the breaking of windows of Jewish-owned businesses and the looting of those stores. In the morning, broken glass littered the ground. Many Jews were physically attacked or harassed, and approximately 30,000 were arrested and sent to concentration camps.
The Soviet Army reached Auschwitz on January 27, 1945. By that time, an estimated 1,500,000 Jews, along with 500,000 Polish prisoners, Soviet POWs and Gypsies, had perished there. As the Western Allies pushed into Germany in the spring of 1945, they liberated Buchenwald, Bergen-Belsen, and Dachau. Now the full horror of the twelve-year Nazi regime became apparent as British and American soldiers, including Supreme Commander Dwight D. Eisenhower, viewed piles of emaciated corpses and listened to vivid accounts given by survivors.
The most notorious physician was Josef Mengele, an SS officer who became the Auschwitz camp doctor on 30 May 1943.[54] Interested in genetics[54] and keen to experiment on twins, he would pick out subjects from the new arrivals during "selection" on the ramp, shouting "Zwillinge heraus!" (twins step forward!).[55] They would be measured, killed, and dissected. One of Mengele's assistants said in 1946 that he was told to send organs of interest to the directors of the "Anthropological Institute in Berlin-Dahlem". This is thought to refer to Mengele's academic supervisor, Otmar Freiherr von Verschuer , director from October 1942 of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics in Berlin-Dahlem.[56][55][i] Mengele's experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change their eye color by injecting chemicals into children's eyes, and amputations and other surgeries.[59]

The Mossad’s South American station chief cabled the headquarters in Israel: “Zvi saw on Gerhard’s farm a person who in form, height, age and dress looks like Mengele.” It later turned out that he was indeed Mengele. Speaking to me in 1999, Aharoni told me: “We were in an excellent mood. I was certain that in a little while we would be able to bring Mengele to Israel to be tried.”

The deportations ... were the work of a much larger apparatus that had to deal with a host of constraints and requirements. The effort, as we shall see, was deemed necessary to accomplish the Final Solution on a European-wide scale.[p.273] 
After the Wannsee Conference in January 1942, the Nazis began the systematic deportation of Jews from all over Europe to six extermination camps established in former Polish territory -- Chelmno , Belzec, Sobibor, Treblinka, Auschwitz-Birkenau, and Majdanek. Extermination camps were killing centers designed to carry out genocide. About three million Jews were gassed in extermination camps.

In the photo below, Captain Franz Hoessler is standing in front of a load of corpses of prisoners who died from typhus at Bergen-Belsen. He is speaking into a microphone for a documentary film made by the British after the Bergen-Belsen camp was turned over to them by Heinrich Himmler on April 15, 1945. He is wearing his SS uniform, but the insignia of his military rank has been removed. Hoessler was convicted by the British and hanged on December 13, 1945 for war crimes that he had committed at Auschwitz-Birkenau, including his participation in the selection of prisoners to be gassed.
At Auschwitz alone, more than 2 million people were murdered in a process resembling a large-scale industrial operation. A large population of Jewish and non-Jewish inmates worked in the labor camp there; though only Jews were gassed, thousands of others died of starvation or disease. During the summer of 1944, even as the events of D-Day (June 6, 1944) and a Soviet offensive the same month spelled the beginning of the end for Germany in the war, a large proportion of Hungary’s Jewish population was deported to Auschwitz, and as many as 12,000 Jews were killed every day.
But there is a note that drills deeper than commemoration: it goes to the idea of identification. To “identify with” is to become what one is not, to become what one is not is to usurp, to usurp is to own—and who, after all, in the half century since Miep Gies retrieved the scattered pages of the diary, really owns Anne Frank? Who can speak for her? Her father, who, after reading the diary and confessing that he “did not know” her, went on to tell us what he thought she meant? Meyer Levin, who claimed to be her authentic voice—so much so that he dared to equate the dismissal of his work, however ignobly motivated, with Holocaust annihilation? Hellman, Bloomgarden, Kanin, whose interpretations clung to a collective ideology of human interchangeability? (In discounting the significance of the Jewish element, Kanin had asserted that “people have suffered because of being English, French, German, Italian, Ethiopian, Mohammedan, Negro, and so on”—as if this were not all the more reason to comprehend and particularize each history.) And what of Cara Wilson and “the children of the world,” who have reduced the persecution of a people to the trials of adolescence?
In response to a typhus epidemic in the women's camp, Mengele cleared one block of six hundred Jewish women and sent them to their deaths in the gas chambers. The building was then cleaned and disinfected, and the occupants of a neighboring block were bathed, de-loused, and given new clothing before being moved into the clean block. This process was repeated until all of the barracks were disinfected. Similar procedures were used for later epidemics of scarlet fever and other diseases, with infected prisoners being killed in the gas chambers. For these actions, Mengele was awarded the War Merit Cross (Second Class with swords) and was promoted in 1944 to First Physician of the Birkenau subcamp.[37]
