German soldiers question Jews after the Warsaw Ghetto Uprising in 1943. In October 1940, the Germans began to concentrate Poland's population of over 3 million Jews into overcrowded ghettos. In the largest of these, the Warsaw Ghetto, thousands of Jews died due to rampant disease and starvation, even before the Nazis began their massive deportations from the ghetto to the Treblinka extermination camp. The Warsaw Ghetto Uprising -- the first urban mass rebellion against the Nazi occupation of Europe -- took place from April 19 until May 16 1943, and began after German troops and police entered the ghetto to deport its surviving inhabitants. It ended when the poorly-armed and supplied resistance was crushed by German troops. #
After the September 1939 German invasion of Poland (the beginning of World War II), anti-Jewish policy escalated to the imprisonment and eventual murder of European Jewry. The Nazis first established ghettos (enclosed areas designed to isolate and control the Jews) in the Generalgouvernement (a territory in central and eastern Poland overseen by a German civilian government) and the Warthegau (an area of western Poland annexed to Germany). Polish and western European Jews were deported to these ghettos where they lived in overcrowded and unsanitary conditions with inadequate food.

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]
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.

German-occupied Denmark rescued most of its own Jews by spiriting them to Sweden by sea in October 1943. This was possible partly because the German presence in Denmark was relatively small. Moreover, while anti-Semitism in the general population of many other countries led to collaboration with the Germans, Jews were an integrated part of Danish culture. Under these unique circumstances, Danish humanitarianism flourished.

After the war, Mengele escaped internment and went underground, serving for four years as a farm stableman near Rosenheim in Bavaria. Then he reportedly escaped, via Genoa, Italy, to South America in 1949. He married (for a second time) under his own name in Uruguay in 1958 and, as “José Mengele,” received citizenship in Paraguay in 1959. In 1961 he apparently moved to Brazil, reportedly becoming friends with an old-time Nazi, Wolfgang Gerhard, and living in a succession of houses owned by a Hungarian couple. In 1985 a team of Brazilian, West German, and American forensic experts determined that Mengele had taken Gerhard’s identity, died in 1979 of a stroke while swimming, and was buried under Gerhard’s name. Dental records later confirmed the forensic conclusion.

Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million.[400] Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories.[401][402] Of Poland's 3.3 million Jews, about 90 percent were killed.[369] Many more died in the ghettos of Poland before they could be deported.[403] The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews.[394] At Auschwitz-Birkenau the Jewish death toll was 1.1 million;[286][404] Treblinka 870,000–925,000;[405] Bełżec 434,000–600,000;[406][287] Chełmno 152,000–320,000;[407][288] Sobibór 170,000–250,000;[408][291] and Majdanek 79,000.[289]
No doubt exists that Mengele was a very active commandant of the Auschwitz camp after he arrived there in 1943. Most doctors who have testified and prisoners who have testified have indicated he was ubiquitous, and, indeed, stories do exist of his selection activities and of his medical involvement. The Frankfurt Court which indicted him charged him with "hideous crimes" committed alone or with others "willfully and with bloodlust". Included in the crimes against humanity were selections, lethal injections, shootings, beatings and other forms of deliberate killing. He was religiously involved in all aspects, but particularly in the twins experiments, according to members of C.A.N.D.L.E.S., twins who survived the experiments.
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.
In the autumn of 1941, SS chief Heinrich Himmler assigned German General Odilo Globocnik (SS and police leader for the Lublin District) with the implementation of a plan to systematically murder the Jews of the Generalgouvernement. The code name Operation Reinhard was eventually given to this plan, named after Heydrich (who was assassinated by Czech partisans in May 1942). As part of Operation Reinhard, Nazi leaders established three killing centers in Poland—Belzec, Sobibor, and Treblinka—with the sole purpose of the mass murder of Jews.
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.

The twins, Bernard and Simon Zajdner, born Dec. 28, 1929, were deported with their sister, Micheline, on May 20, 1944.They were victims of Josef Mengele's inhuman "medical experiments." Eva Mozes and her identical twin, Miriam, were survivors of the deadly genetic experiments conducted by Josef Mengele. Their parents, grandparents, two older sisters, uncles, aunts and cousins were killed in the Holocaust. After the liberation of the camp, Eva and Miriam were the first two twins in the famous film taken by the Soviets - often shown in footage about the horrors of Holocaust.
Once the Nazis took over Budapest in 1944 and began deporting Jews to the death camps, Lutz negotiated a special deal with the Hungarian government and the Nazis: he had permission to issue protective letters to 8,000 Hungarian Jews for emigration to Palestine. Lutz then deliberately misinterpreted his permission for 8,000 as applying to families rather than individuals, and proceeded to issue tens of thousands of additional protective letters, all of them bearing a number between one and 8,000. He also set up some 76 safe houses around Budapest, declaring them annexes of the Swiss legation. Among the safe houses was the now well-known "Glass House" (Üvegház) at Vadász Street 29. About 3,000 Jews found refuge at the Glass House and in a neighboring building.
As the unsuspecting people were herded off the train and ordered into separate lines, SS officers shouted in German, "Zwillinge!" (Twins!). Parents were forced to make a quick decision. Unsure of their situation, already being separated from family members when forced to form lines, seeing barbed wire, smelling an unfamiliar stench -- was it good or bad to be a twin?

Their decency exposed them to the dangers of discovery and denunciation. If caught, they faced torture, deportation to concentration camps, or execution. Their behavior was atypical even in their own communities, where the attitude of the majority was characterized by inertia, indifference, and open complicity in the persecution and mass murder of Europe’s Jews.
The Diary of Anne Frank is the first, and sometimes only, exposure many people have to the history of the Holocaust. Meticulously handwritten during her two years in hiding, Anne's diary remains one of the most widely read works of nonfiction in the world. Anne has become a symbol for the lost promise of the more than one million Jewish children who died in the Holocaust.
On 31 May 1985, acting on intelligence received by the West German prosecutor's office, police raided the house of Hans Sedlmeier, a lifelong friend of Mengele and sales manager of the family firm in Günzburg.[109] They found a coded address book and copies of letters sent to and received from Mengele. Among the papers was a letter from Wolfram Bossert notifying Sedlmeier of Mengele's death.[110] German authorities alerted the police in São Paulo, who then contacted the Bosserts. Under interrogation, they revealed the location of Mengele's grave,[111] and the remains were exhumed on 6 June 1985. Extensive forensic examination indicated with a high degree of probability that the body was indeed that of Josef Mengele.[112] Rolf Mengele issued a statement on 10 June confirming that the body was his father's, and he admitted that the news of his father's death had been concealed in order to protect the people who had sheltered him for many years.[113]

After several months on the run, including a trip back to the Soviet-occupied area to recover his Auschwitz records, Mengele found work near Rosenheim as a farmhand.[62] He eventually escaped from Germany on 17 April 1949,[63][64] convinced that his capture would mean a trial and death sentence. Assisted by a network of former SS members, he used the ratline to travel to Genoa, where he obtained a passport from the International Committee of the Red Cross under the alias "Helmut Gregor", and sailed to Argentina in July 1949.[65] His wife refused to accompany him, and they divorced in 1954.[66]
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.

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.”
In order to make way for these new prisoners, the SS took many thousands of Jews from the ghettos of Kovno, Riga, Minsk, Łódź, Lvov and Lublin to be murdered by the Einsatzgruppen. Even though the SS claimed to be the hardened ‘Master Race’, quite a few of them found it ‘difficult’ to murder women and children. In addition, the shooting process used by the Einsatzgruppen was expensive.

Many rescuers exhibited a longstanding commitment to help the needy. This commitment was reflected in their habitual engagement in a range of charitable activities. For example, beggars and vagabonds who reached Jan Rybak’s village had routinely been directed to him. Similarly, when neighbors were overburdened with chores, Rybak would step in to help.

From the earliest years of the Nazi regime, German authorities persecuted homosexuals and others whose behavior did not match prescribed social norms. German police officials targeted thousands of political opponents (including Communists, Socialists, and trade unionists) and religious dissidents (such as Jehovah's Witnesses). Many of these individuals died as a result of incarceration and maltreatment.
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.
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]
