Lengyel described how Dr. Mengele would take all the correct medical precautions while delivering a baby at Auschwitz, yet only a half hour later, he would send the mother and baby to be gassed and burned in the crematorium. Lengyel herself was selected for the gas chamber, but managed to break away from the group of women who had been selected, before the truck arrived to take the prisoners to the crematorium.
While the labour camps at Auschwitz and Majdanek used inmates for slave labour to support the German war effort, the extermination camps at Belzec, Treblinka, and Sobibor had one task alone: killing. At Treblinka a staff of 120, of whom only 30 were SS (the Nazi paramilitary corps), killed some 750,000 to 925,000 Jews during the camp’s 17 months of operation. At Belzec German records detail a staff of 104, including about 20 SS, who killed some 500,000 Jews in less than 10 months. At Sobibor they murdered between 200,000 and 250,000. These camps began operation during the spring and summer of 1942, when the ghettos of German-occupied Poland were filled with Jews. Once they had completed their missions—murder by gassing, or “resettlement in the east,” to use the language of the Wannsee protocols—the Nazis closed the camps. There were six extermination camps, all in German-occupied Poland, among the thousands of concentration and slave-labour camps throughout German-occupied Europe.
Unlike Belzec, Sobibor, Treblinka, and Lublin-Majdanek,[96] which were built in the occupied General Government territory inhabited by the largest concentrations of Jews,[97] the killing centre at Auschwitz subcamp of Birkenau operated in Polish areas annexed by Nazi Germany directly. The new gas chambers at Bunker I were finished around March 1942 when the Final Solution was officially launched at Belzec. Until mid-June 20,000 Silesian Jews were killed there using Zyklon B. In July 1942, Bunker II became operational. In August, another 10,000–13,000 Polish Jews from Silesia perished,[98] along with 16,000 French Jews declared 'stateless',[99] and 7,700 Jews from Slovakia.[98]
Concentration camps were top priority in the conference. ""Nazis would trap Jews in ghettos'' said Himmler. Then they were taken to death camps. Auschwitz mainly. They killed 1 to 3 million people there. '' Under proper guidance in the Final Solution the Jews are to be relocated for appropriate  labor in the east. Able-bodied Jews will be separated according to sex. Then taken in large work columns to work on roads of course many will die of natural causes.'' Himmler said this during the conference.
The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
In early 1943, encouraged by von Verschuer, Mengele applied to transfer to the concentration camp service.[20][30] His application was accepted and he was posted to Auschwitz, where he was appointed by SS-Standortarzt Eduard Wirths, chief medical officer at Auschwitz, to the position of chief physician of the Zigeunerfamilienlager (Romani family camp) at Birkenau,[20][30] a subcamp located on the main Auschwitz complex. The SS doctors did not administer treatment to the Auschwitz inmates, but supervised the activities of inmate doctors who had been forced to work in the camp medical service.[31] As part of his duties, Mengele made weekly visits to the hospital barracks and ordered any prisoners who had not recovered after two weeks in bed to be sent to the gas chambers.[32]

This past fall, I reached out to Hana Amir, Zeidel’s daughter, and we spoke several times over Skype. From her home in Tel Aviv, Amir, who is slight and spectacled, with a gray bob, told me about how she learned of her father’s story. When Amir was young, Zeidel worked as a truck driver, and he was gone for long stretches at a time. At home, he was withholding with his daughter and two sons. “My father was of a generation that didn’t talk about their emotions, didn’t talk about how they felt about what they’d been through,” Amir told me. “This was their coping mechanism: If you’re so busy with moving forward, you can disconnect from your memories.” But there were signs that the past wasn’t done with Zeidel: Amir believes he suffered from recurrent nightmares, and he was fastidious about his personal hygiene—he washed his hands many times a day.
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.
Dogim backed down; the diggers pressed on. On April 9, Farber announced that they’d reached the roots of a tree near the barbed-wire fence that encircled the camp’s perimeter. Three days later, he made a tentative stab with a makeshift probe he’d fashioned out of copper tubing. Gone was the stench of the pits. “We could feel the fresh April air, and it gave us strength,” he later recalled. “We saw with our own eyes that freedom was near.”

At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]
In 1944, Josiah DuBois, Jr. wrote a memorandum to then-Secretary of the Treasury Henry Morgenthau, Jr. entitled “Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews”, which condemned the bureaucratic interference of U.S. State Department policies in obstructing the evacuation of Holocaust Refugees from Romania and Occupied France. The Report would spur the Roosevelt administration to create the War Refugee Board later that year.
Amir told me that Zeidel made several pilgrimages back to Ponar. And yet he was never able to locate the passageway that carried him to freedom. What Zeidel didn’t know was that three years before he died, a Lithuanian archaeologist named Vytautas Urbanavicius had quietly excavated what turned out to be the tunnel’s entrance. But after taking a few photographs and a notebook’s worth of measurements, he sealed up the hole with fresh mortar and stone without pressing any farther or prominently marking the area.
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.

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]
Prior to his arrival at Auschwitz, he had published three articles, one of which was his dissertation in the Anthropological Institute at the University of Munich and which was entitled "Racial-Morphological Examination of the Anterior Portion of the Lower Jaw in Four Racial Groups". His medical dissertation, published in 1938, was entitled "Genealogical Studies in the Cases of Cleft Lip-Jaw-Palate". This was a predecessor to his work on genetic abnormalities and indirectly on twins which was to take place at Auschwitz. The third article - entitled "Hereditary Transmission of Fistulae Auris" was published in conjunction with research done on the Lenz-Vershuer principle of "irregular, dominant hereditary process". It appeared in 1928 that Mengele was destined for the academia.
Double-sided ramps were built inside the pits. One crew hauled stretchers filled with corpses up the ramp, and another crew pushed the bodies onto the pyre. In a week, the Burning Brigade might dispose of 3,500 bodies or more. Later, the guards forced prisoners to sift through the ashes with strainers, looking for bone fragments, which would then be pounded down into powder.
About two-thirds of the overall number of victims of the Final Solution were killed before February 1943,[87] which included the main phase of the extermination programme in the West launched by Eichmann on 11 June 1942 from Berlin.[88] The Holocaust trains run by the Deutsche Reichsbahn and several other national railway systems delivered condemned Jewish captives from as far as Belgium, Bulgaria, France, Greece, Hungary, Italy, Moravia, Netherlands, Romania, Slovakia, and even Scandinavia.[89][90] The cremation of exhumed corpses to destroy any evidence left behind began in early spring and continued throughout summer.[91] The nearly completed clandestine programme of murdering all deportees was explicitly addressed by Heinrich Himmler in his Posen speeches made to the leadership of the Nazi Party on 4 October and during the Posen Conference of 6 October 1943 in occupied Poland. Himmler explained why the Nazi leadership found it necessary to kill Jewish women and children along with the Jewish men. The assembled functionaries were told that the Nazi state policy was "the extermination of the Jewish people" as such.[92]
On 15 September 1935, the Reichstag passed the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor, known as the Nuremberg Laws. The former said that only those of "German or kindred blood" could be citizens. Anyone with three or more Jewish grandparents was classified as a Jew.[107] The second law said: "Marriages between Jews and subjects of the state of German or related blood are forbidden." Sexual relationships between them were also criminalized; Jews were not allowed to employ German women under the age of 45 in their homes.[108] The laws referred to Jews but applied equally to the Roma and black Germans.[107]
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.
David Cesarani emphasises the improvised, haphazard nature of Nazi policies in response to changing war time conditions in his overview, Final Solution: The Fate Of The European Jews 1933–49 (2016). "Cesarani provides telling examples", wrote Mark Roseman, "of a lack of coherence and planning for the future in Jewish policy, even when we would most expect it. The classic instance is the invasion of Poland in 1939, when not even the most elementary consideration had been given to what should happen to Poland's Jews either in the shorter or longer term. Given that Poland was home to the largest Jewish population in the world, and that, in a couple of years, it would house the extermination camps, this is remarkable."[118]

Another Polish courier, Jan Karski, reached the west in November 1942, carrying messages from Jewish leaders in Poland. He had himself witnessed the conditions in the Warsaw ghetto and in what he believed to be the Belzec death camp, and was eager to inform the world. Karski saw the British foreign secretary, Anthony Eden, and US President Roosevelt, but they seemed to be more interested in military intelligence than in atrocity stories. Partly as a result of Karski's mission, however, the Allies agreed to a joint declaration, read to the British Parliament on 17 December, which acknowledged Nazi war crimes and threatened punishment for the perpetrators. Subsequently millions of leaflets were dropped in the course of bombing raids on German cities to inform Germans of the facts, but these had little or no effect.
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.
The Wannsee Conference, a meeting between the SS (the elite guard of the Nazi state) and German government agencies, opens in Berlin. They discuss and coordinate the implementation of the "Final Solution," which is already under way. At Wannsee, the SS estimates that the "Final Solution" will involve 11 million European Jews, including those from non-occupied countries such as Ireland, Sweden, Turkey, and Great Britain. Between the fall of 1941 and the fall of 1944, the German railways transport millions of people to their deaths in killing centers in occupied Poland.

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] 
It is estimated that by 1942 Einsatzgruppen had killed more than 1 million Soviet troops. These victims were either shot or gassed. Jews were not the only ones killed. People who opposed Hitler were also murdered. 20th century techniques of mass production were applied in the Final Solution. Engineers of the Final Solution used these ways to cheaply and efficiently murder millions of Jews there were many ways the Nazis murdered people. Some ways were crematoriums, electrocution, injections, flame throwers, hand grenades, and gas chambers. Units of the S.S. that were specially trained followed German troops called the first wave. These squads made up the Einsatzgruppen. Nazis genocide was targeted towards Jews mass murder was targeted towards other Non-Aryans.      

Anne Frank's extraordinary diary, written in the Amsterdam attic where she and her family hid from the Nazis for two years, has become a world classic and a timeless testament to the human spirit. Now, in a new edition enriched by many passages originally withheld by her father, we meet an Anne more real, more human, and more vital than ever. Here she is first and foremost ...more
Meanwhile, sightings of Josef Mengele were being reported all over the world. Wiesenthal claimed to have information that placed Mengele on the Greek island of Kythnos in 1960,[103] in Cairo in 1961,[104] in Spain in 1971,[105] and in Paraguay in 1978, eighteen years after he had left the country.[106] He insisted as late as 1985 that Mengele was still alive—six years after he had died—having previously offered a reward of US$100,000 in 1982 for the fugitive's capture.[107] Worldwide interest in the case was heightened by a mock trial held in Jerusalem in February 1985, featuring the testimonies of over one hundred victims of Mengele's experiments. Shortly afterwards, the West German, Israeli, and U.S. governments launched a coordinated effort to determine Mengele's whereabouts. The West German and Israeli governments offered rewards for his capture, as did The Washington Times and the Simon Wiesenthal Center.[108]
