Executions by the Einsatzgruppen, mobile killing squads,were abandoned for practical reasons. Although approximately 1.5 million Jews had been shot by the winter of 1941, the Nazis felt that the efficiency of this slow and cumbersome method left much to be desired. Moreover, they found it was bad for the sol­diers’ morale. Himmler himself, commander of the SS and as such responsible for the annihilation of the Jews, was persuaded, after having witnessed such an execu­tion, that it badly affected the mental health of those carrying out the execution. The institutionalization of organized murder, founded on a division of labor and carried out in special installations expressly designed for this purpose, distanced the executioner from the victim, an indispensable psychological advantage in an enterprise of annihilation of such a huge scale.
Soon after, a Mossad surveillance team saw a man matching Mengele’s description enter a pharmacy owned by a person who was known to be in touch with him. On July 23, 1962, the Mossad operative Zvi Aharoni (who had identified Eichmann two years earlier) was on a dirt road by the farm where Mengele was believed to be hiding when he encountered a group of men — including one who looked exactly like the fugitive.

Like most “scientists” at work in the concentration camp environment, Mengele enlisted the aid of trained medical professionals among the prisoner population to perform the more grisly, or mundane, tasks and to carry out autopsies upon his dead victims. Much of our early knowledge of Mengele's activities at Auschwitz comes from Dr. Miklos Nyiszli, a prisoner-physician who assisted Mengele under duress. Nyiszli published his experiences, initially in his native Hungarian, in 1946. His work Auschwitz: A Doctor's Eyewitness Account appeared in English in 1960.

Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]

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.
Wounded while on campaign, Mengele returned to Germany in January 1943. He began work at the Kaiser Wilhelm Institute (KWI) for Anthropology, Human Genetics, and Eugenics, directed by his former mentor von Verschuer. In April of 1943, he received a promotion to the rank of SS captain. This promotion shortly preceded Mengele's transfer to Auschwitz, on May 30, 1943.
From this moment on, the Nazi regime adopted hundreds of laws restricting the rights and liberties of the Jewish people. Jews were expelled from the civil service and barred from entering particular professions, stripped of their citizenship, and forbidden from intermarrying or even having a relationship with anyone of “German or German-related blood”.

SS Officer Hosler, under arrest, stands in front of a truck which is loaded with corpses at Belsen concentration camp  © The Final Solution moved into its last stages as Allied forces began to close in on Germany in 1944. The Project Reinhardt camps were razed. A prisoner work-gang called the Blobel Commando began digging up and burning the bodies of those killed by the Einsatzgruppen. Prisoners remaining in Auschwitz and other concentration camps were transported or force-marched to camps within Germany. Hardly fit for such an effort, thousands of prisoners on these death marches succumbed to starvation, exhaustion and cold, or were shot for not keeping up the pace.
At each of the death camps, special squads of Jewish slave laborers called Sonderkommandos were utilized to untangle the victims and remove them from the gas chamber. Next they extracted any gold fillings from teeth and searched body orifices for hidden valuables. The corpses were disposed of by various methods including mass burials, cremation in open fire pits or in specially designed crematory ovens such as those used at Auschwitz. All clothing, money, gold, jewelry, watches, eyeglasses and other valuables were sorted out then shipped back to Germany for re-use. Women's hair was sent to a firm in Bavaria for the manufacture of felt.
Mengele earned his first doctorate in anthropology from the University of Munich in 1935. He did his post-doctoral work at Frankfurt under Dr. Otmar Freiherr von Verschuer, who was a fully indoctrinated Nazi eugenicist. National Socialism always held that individuals were the product of their heredity, and von Verschuer was one of the Nazi-aligned scientists whose work seemed to legitimize that assertion.
Anne’s childhood, by contrast, fell into shadows almost immediately. She was not yet four when the German persecutions of Jews began, and from then until the anguished close of her days she lived as a refugee and a victim. In 1933, the family fled from Germany to Holland, where Frank had commercial connections, and where he established a pectin business. By 1940, the Germans had occupied the Netherlands. In Amsterdam, Jewish children, Anne among them, were thrown out of the public-school system and made to wear the yellow star. At thirteen, on November 19, 1942, already in hiding, Anne Frank could write:
 “I would do it all again.” Edeltrud Posiles uttered these words in 2011 when she was the last surviving Righteous Gentile who had hid Jews in Nazi Austria. When Posiles – then Becher – heard a knock on the door in 1942, she opened it to find her Jewish fiancé and his two brothers on her doorstep. As described at the DailyMail.com, “Hiding Jews was punishable by death. But the feisty 94-year old [said] ‘there was never a moment’s doubt in my mind,’ when asked if she hesitated as she was asked by the brothers for sanctuary.”
On April 30, 1945, surrounded by the Soviet Army in Berlin, Adolf Hitler committed suicide and his Reich soon collapsed. By now, most of Europe's Jews had been killed. Four million had been gassed in the death camps while another two million had been shot dead or died in the ghettos. The victorious Allies; Britain, the United States, and the Soviet Union, then began the daunting task of sorting through the carnage to determine exactly who was responsible. Seven months later, the Nuremberg War Crime Trials began, with 22 surviving top Nazis charged with crimes against humanity.
Racial-Morphological Examinations of the Anterior Portion of the Lower Jaw in Four Racial Groups. This dissertation, completed in 1935 and first published in 1937, earned him a PhD in anthropology from Munich University. In this work Mengele sought to demonstrate that there were structural differences in the lower jaws of individuals from different ethnic groups, and that racial distinctions could be made based on these differences.[7][121]

The Germans required each ghetto to be run by a Judenrat, or Jewish council.[205] Councils were responsible for a ghetto's day-to-day operations, including distributing food, water, heat, medical care, and shelter. The Germans also required councils to confiscate property, organize forced labor, and, finally, facilitate deportations to extermination camps.[206] The councils' basic strategy was one of trying to minimize losses, by cooperating with German authorities, bribing officials, and petitioning for better conditions or clemency.[207]
But for all that this book has been set up as a work of Christian ethics and in that I think the book fails there is next to no specifically Christian ethical content. Why should one risk the lives of oneself and one's family for a stranger? Is the fact that so many didn't amount, as Eliezer Berkovits put it to "the moral bankruptcy of Christian civilization and the spiritual bankruptcy of Christian religion"? On these points Gushee is silent. And so, this book does not offer an account of the moral obligation the disciple of Christ owe to the persecuted Jew in particular or the persecuted stranger in general. It does however ask a very important question, and that alone makes this a book worth taking seriously.

The ghettos, and the slow death they brought, were only part of the overall plan. In the months following the Wannsee Conference, three specialized killing centers, Belzec, Treblinka and Sobibor, were constructed in southeast Poland, featuring large gas chambers with adjacent crematories or burial pits for the disposal of corpses. After they became operational, the ghettos were bypassed and Jews went directly by train to the new death camps.
Back in Germany, years of pent-up hatred toward the Jews was finally let loose on the night that marks the actual beginning of the Holocaust. The Night of Broken Glass (Kristallnacht) occurred on November 9/10 after 17-year-old Herschel Grynszpan shot and killed Ernst vom Rath, a German embassy official in Paris, in retaliation for the harsh treatment his Jewish parents had received from Nazis.
From 1933 onward, anti-Jewish propaganda had flooded Germany. Under the skillful direction of Joseph Goebbels, his Nazi Propaganda Ministry churned out a ceaseless stream of leaflets, posters, newspaper articles, cartoons, newsreels, slides, movies, speeches, records, exhibits and radio pronouncements. As a result, the accusations, denunciations and opinions which Hitler first expressed in his book, Mein Kampf, had become institutionalized, accepted as time-tested beliefs by all Nazis, taught as fact to impressionable youths, and drilled into the minds of eager-to-please SS recruits.
According to the Quad City Times, Yanina Cywinska was a 10-year-old student at the Kirov Ballet in Leningrad (now St. Petersburg) when her Polish Catholic parents suddenly called her home to Warsaw. Cywinska's parents, a physician and an artist, worked to assist Jews imprisoned in the Warsaw ghetto during the Nazi occupation of Poland until they themselves were placed in a Warsaw detention center. Once the family boarded trains for Auschwitz, Yanina would never see her parents or brother again.
According to the copyright laws in the European Union, as a general rule, rights of authors end seventy years after their death. Hence, the copyright of the diary expired on 1 January 2016. In the Netherlands, for the original publication of 1947 (containing parts of both versions of Anne Frank's writing), as well as a version published in 1986 (containing both versions completely), copyright initially would have expired not 50 years after the death of Anne Frank (1996), but 50 years after publication, as a result of a provision specific for posthumously published works (1997 and 2036, respectively).

The Final Solution was a plan of Adolf Hitler's to kill all the Jews in Europe. Hitler's Anti- Semitic ideas were so strong that he released hatred by mass murder. Before Hitler decided to become dictator the Final Solution was already in his head. In a couple of books written by Gerald Fleming Hitler says '' Once I  am really in power my first task will be the genocide of the Jews .'' He achieved his goal by killing six million Jews. Hitler began  the final solution in every European Nation he was  control of. The Jews were sent to concentration/death camps.
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.[2][3]
