The Nuremberg Laws, issued on Sept. 15, 1935, was designed to exclude Jews from public life. The Nuremberg Laws stripped German Jews of their citizenship and prohibited marriages and extramarital sex between Jews and Gentiles. These measures set the legal precedent for anti-Jewish legislation that followed. Nazis issued numerous anti-Jewish laws over the next several years. Jews were banned from public parks, fired from civil service jobs, and forced to register their property. Other laws barred Jewish doctors from treating anyone other than Jewish patients, expelled Jewish children from public schools, and placed severe travel restrictions on Jews.
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.
Although the composition of the ground, largely sand, was favorable for ground-penetrating radar, the dense forest surrounding the site interfered enough with the radar signals that they decided to try another tack. Paul Bauman and Alastair McClymont, geophysicists with Advisian WorleyParsons, a transnational engineering company, had more luck with electrical resistivity tomography, or ERT, which was originally developed to explore water tables and potential mining sites. ERT technology sends jolts of electrical current into the earth by way of metal electrodes hooked up to a powerful battery and measures the distinctive levels of resistivity of different types of earth; the result is a detailed map to a depth of more than a hundred feet.
Before World War II, Germany considered mass deportation from Europe of German, and later European, Jewry.[130] Among the areas considered for possible resettlement were British Palestine[131] and French Madagascar.[132] After the war began, German leaders considered deporting Europe's Jews to Siberia.[133][134] Palestine was the only location to which any German relocation plan produced results, via the Haavara Agreement between the Zionist Federation of Germany and the German government.[135] This resulted in the transfer of about 60,000 German Jews and $100 million from Germany to Palestine, but it ended with the outbreak of World War II.[136] In May 1940 Madagascar became the focus of new deportation efforts[132] because it had unfavorable living conditions that would hasten deaths.[137] Several German leaders had discussed the idea in 1938, and Adolf Eichmann's office was ordered to carry out resettlement planning, but no evidence of planning exists until after the fall of France in June 1940.[138] But the inability to defeat Britain prevented the movement of Jews across the seas,[139] and the end of the Madagascar Plan was announced on 10 February 1942.[140]
The forest burst orange with gunfire. “I looked around: Our entire path was filled with people crawling,” Farber has written. “Some jumped up and started running in various directions.” Farber and Dogim cut through the fence and tore off into the woods, with Zeidel and three others in tow. The men ran all night, through rivers, through forests, past villages. After a week, the escapees were deep inside the Rudnitsky Woods. Farber introduced himself to the partisan leader. “Where do you come from?” the man asked.
Nolte's views were widely denounced. The debate between the "specifists" and "universalists" was acrimonious; the former feared debasement of the Holocaust and the latter considered it immoral to hold the Holocaust as beyond compare.[478] In her book Denying the Holocaust (1993), Deborah Lipstadt viewed Nolte's position as a form of Holocaust denial, or at least "the same triumph of ideology over truth".[479] Addressing Nolte's argument, Eberhard Jäckel wrote in Die Zeit in September 1986 that "never before had a state, with the authority of its leader, decided and announced that a specific group of humans, including the elderly, women, children and infants, would be killed as quickly as possible, then carried out this resolution using every possible means of state power".[h] Despite the criticism of Nolte, Dan Stone wrote in 2010 that the Historikerstreit put "the question of comparison" on the agenda.[480] He argued that the idea of the Holocaust as unique has been overtaken by attempts to place it within the context of early-20th-century Stalinism, ethnic cleansing, and the Nazis' intentions for post-war "demographic reordering", particularly the Generalplan Ost, the plan to kill tens of millions of Slavs to create living space for Germans.[481] The specifist position continued nevertheless to inform the views of many specialists. Richard J. Evans argued in 2015:
Who among gentile Poles was most likely to stand up for persecuted Jews? What propelled these rescuers to risk their lives for them? What characteristics, motivations, and circumstances did the rescuers share? Most attempts to answer these questions focus upon standard sociological categories: researchers consider the rescuers’ class, education, political and religious commitments, friendships with Jews, and level of anti-Jewish prejudice. The results of such investigations have not led to clear conclusions. Some studies suggest that economically deprived Christians more readily identified with Jewish suffering. Others conclude that intellectuals were more likely to have been protectors because they had better insight into German aims and were committed to undermining them.
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]
The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators. Holocaust is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were an alien threat to the so-called German racial community.

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]

Most of the book is about the privations and hardship of living hidden away in the "annex". There is very little coverage of the violence of the times or much that is going on in the outside world because they had little knowledge of it since they were hidden. I think this is partly why some schoolchildren report the diary is boring. It does get repetitive at times, which reflects the feelings of those living in hiding. They had to wait and wait in fear, not knowing what the next day would bring.

For the German rulers, the ghetto was a temporary measure, a holding pen for the Jewish population until a policy on its fate could be established and implemented. For the Jews, ghetto life was the situation under which they thought they would be forced to live until the end of the war. They aimed to make life bearable, even under the most trying circumstances. When the Nazis prohibited schools, they opened clandestine schools. When the Nazis banned religious life, it persisted in hiding. The Jews used humour as a means of defiance, so too song. They resorted to arms only late in the Nazi assault.

Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for human experimentation.[2] His medical procedures showed no consideration for the health, safety, or physical and emotional suffering of the victims.[2][3] He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarfs, and people with physical abnormalities.[2] A grant was provided by the Deutsche Forschungsgemeinschaft (German Research Foundation), at the request of von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau.[38] Dr. Miklós Nyiszli, a Hungarian Jewish pathologist who arrived in Auschwitz on 29 May 1944, performed dissections and prepared specimens for shipment in this laboratory.[39] The twin research was in part intended to prove the supremacy of heredity over environment and thus strengthen the Nazi premise of the superiority of the Aryan race.[40] Nyiszli and others reported that the twin studies may also have been motivated by an intention to increase the reproduction rate of the German race by improving the chances of racially desirable people having twins.[41]
