Browning describes the creation of the extermination camps, which were responsible for the largest number of deaths in the Final Solution, as bringing together three separate developments within the Third Reich: the concentration camps which had been established in Germany since 1933; an expansion of the gassing technology of the Nazi euthanasia programme to provide killing mechanism of greater efficiency and psychological detachment; and the creation of "factories of death" to be fed endless streams of victims by mass uprooting and deportation that utilized the experience and personnel from earlier population resettlement programmes—especially the HSSPF and Adolf Eichmann's RSHA for "Jewish affairs and evacuations".[115]
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.)
I confess to feeling slightly voyeuristic while reading this. It was constantly in the back of my mind that this was no ordinary novel, or even a true-to-life account. This was someone’s diary. Every page written in confidence, each word revealing the thoughts closest to the heart of this young girl. As a journal-keeper myself, I sometimes find myself wondering, “What if someone else were to read this?” which causes me to wonder how much to filter my words. But then, isn’t the purpose of a diary ...more

At the same time, the Germans set about liquidating the ghettos in occupied Poland. July 22, 1942, when the deportation of Jews from Warsaw to the death camp in Treblinka began, is regarded as a symbolic date. A decided majority of the Polish Jews were killed in a little over half a year, after which the SS began liquidating the Aktion Reinhard camps. However, the last great death camp—Auschwitz—remained in existence until the beginning of 1945. It was mainly Jews from Western and Southern Europe, from the liquidated labor camps, and the ghettos in Sosnowiec and Łódź, who died in the gas chambers there.
Olga Lengyel, a prisoner at the Birkenau camp, wrote in her book entitled "Five Chimneys" that she had heard about Dr. Mengele from the other inmates before she saw him. Lengyel wrote that she had heard that Dr. Mengele was "good-looking" but she was surprised by how "really handsome" he was. Lengyel wrote, regarding Dr. Mengele: "Though he was making decisions that meant extermination, he was as pleasantly smug as any man could be."
In 1933, Jews in Germany numbered around 525,000, or only 1 percent of the total German population. During the next six years, Nazis undertook an “Aryanization” of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients. Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).
More than 140 years after Louis Braille invented the Braille reading system, Seiichi Miyake came up with a different system based on touch that allows visually impaired people to navigate public spaces. Today, tactile paving is used by major cities and transportation services around the world. Miyake was so influential that he's the subject of the Google Doodle for March 18, the 52nd anniversary of tactile paving's debut.
The conference at Wannsee gave impetus to the so-called second sweep of the Holocaust by the bullet in the east. Between April and July 1942 in Volhynia, 30,000 Jews were murdered in death pits with the help of dozens of newly formed Ukrainian Schutzmannschaft.[67] Owing to good relations with the Ukrainian Hilfsverwaltung,[68] these auxiliary battalions were deployed by the SS also in Russia Center, Russia South, and in Byelorussia; each with about 500 soldiers divided into three companies.[69] They participated in the extermination of 150,000 Volhynian Jews alone, or 98 percent of the Jewish inhabitants of the entire region.[70] In July 1942 the Completion of the Final Solution in the General Government territory which included Distrikt Galizien, was ordered personally by Himmler. He set the initial deadline for 31 December 1942.[71]
Upon arrival at a camp in mates were stripped of their clothes and shaved of all their body hair. Then they were given a shower, disinfected and given a uniform. each step was used to dehumanize prisoners, both physically and emotionally. Prisoners were then given a number. At Auschwitz the number was tattooed on their arm. Those who the Nazis thought were unable to work were token to what they called showers. The Nazis said to these prisoners who were about to meet their deaths it was to freshen up a bit after their long journey. Instead of water Zyklon B, developed to kill rodents, closed in on them. Death Did not usually come quickly but rather slowly. Most of the walls of the death chambers had scratch marks to show how victims tried to dig themselves out. The purpose of these cams were to kill huge amounts of Jews a day. Camps had been in Germany for years. These were the places  were tons of Jews had been murdered. Once at the camps selected people would work the others were gassed. Before being gassed they forced to march to the sound of music. An important camp was Treblinka. It was established for slave labor In 1941, but in 1942 it became a death camp. By may 1943 the population of Warsaw had been transported to Treblinka and other camps. By July 11, 1944 800,000 Jews had been murdered in Treblinkia. Unlike Treblinkia, Chelmno, Sobibor, and Balzac which were made to kill Jews. Maidanek and Auschwitz had a work camp attached. Upon arrival at these two camps a selection was made. 10% of the new arrivals would escape immediate gassing.   

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.

Being a twin, regardless of age, meant survival in 1944. Some 3,000 children (or about 1,500 sets of twins) were selected for the experiments. They were not terrified of him but rather they were often intimidated by some of what he did. They knew of his temper and his passion for his work. Yet, they were also aware of his role in their survival. "Being on Mengele’s list was better than being on no list," said Eva Mozes Kor.

But they were gradually shut out of German society by the Nazis through a never-ending series of laws and decrees, culminating in the Nuremberg Laws of 1935 which deprived them of their German citizenship and forbade intermarriage with non-Jews. They were removed from schools, banned from the professions, excluded from military service, and were even forbidden to share a park bench with a non-Jew.
After only four days of working in Hamburg, Ruth Elias was escorted by an SS man, in a private compartment on a passenger train, to the infirmary at Ravensbrück, the women's concentration camp near Berlin. From there, Ruth and Berta Reich, another prisoner who was nine months pregnant, were soon sent back to Auschwitz on another passenger train. Ruth gave birth to a baby girl at Auschwitz, but Dr. Mengele cruelly ordered her to bind her breasts and not to nurse her child because he wanted to see how long it would take for a baby to die without its mother's milk. Mercifully, a woman dentist named Maca Steinberg, who was a prisoner at Auschwitz, obtained some morphine and gave it to Ruth so that she could inject her baby and end its life, after Ruth told her that Dr. Mengele was due to arrive the next morning to take Ruth and her child to the gas chamber.

Himmler ordered the closure of ghettos in Poland in mid-July 1942; most inhabitants were sent to extermination camps. Those Jews needed for war production would be confined in concentration camps.[220] The deportations from the Warsaw Ghetto began on 22 July; over the almost two months of the Aktion, until 12 September, the population was reduced from 350,000 to 65,000. Those deported were transported in freight trains to the Treblinka extermination camp.[221] Similar deportations happened in other ghettos, with many ghettos totally emptied.[222] The first ghetto uprisings occurred in mid-1942 in small community ghettos.[223] Although there were armed resistance attempts in both the larger and smaller ghettos in 1943, in every case they failed against the overwhelming German military force, and the remaining Jews were either killed or deported to the death camps.[224]
2) Our inner duty: a “Yizkor for the Righteous Gentiles” inserts this heroic chapter into the memory of the Holocaust, as reflected in ceremonies across Israel. Ceremonies are indeed too narrow a tool to hold the spectrum of questions and meanings raised by the Holocaust. And yet their very existence testifies to our need for them, precisely because it is within them that we experience a temporary unity of time, place, and meaning. Through them we find essential meaning for ourselves and for our children in the myriad messages arising from the Holocaust at any given moment. This is why it is so important that in this capsulated message, there will be room also for those people who chose to do good, risking life and limb, within an impossibly evil reality.

Paradoxically, at the same time that Germany tried to rid itself of its Jews via forced emigration, its territorial expansions kept bringing more Jews under its control. Germany annexed Austria in March 1938 and the Sudetenland (now in the Czech Republic) in September 1938. It established control over the Protectorate of Bohemia and Moravia (now in the Czech Republic) in March 1939. When Germany invaded Poland on September 1, 1939, the “Jewish question” became urgent. When the division of Poland between Germany and the Soviet Union was complete, more than two million more Jews had come under German control. For a time, the Nazis considered shipping the Jews to the island of Madagascar, off the southeast coast of Africa, but discarded the plan as impractical; the Nazis had not prevailed in the Battle of Britain, the seas had become a war zone, and the resources required for such a massive deportation were scarce.

By now, experimental mobile gas vans were being used by the Einsatzgruppen to kill Jews in Russia. Special trucks had been converted by the SS into portable gas chambers. Jews were locked up in the air-tight rear container while exhaust fumes from the truck's engine were fed in to suffocate them. However, this method was found to be somewhat impractical since the average capacity was less than 50 persons. For the time being, the quickest killing method continued to be mass shootings. And as Hitler's troops advanced deep into the Soviet Union, the pace of Einsatz killings accelerated. Over 33,000 Jews in the Ukraine were shot in the Babi Yar ravine near Kiev during two days in September 1941.
Policies differed widely among Germany’s Balkan allies. In Romania it was primarily the Romanians themselves who slaughtered the country’s Jews. Toward the end of the war, however, when the defeat of Germany was all but certain, the Romanian government found more value in living Jews who could be held for ransom or used as leverage with the West. Bulgaria deported Jews from neighbouring Thrace and Macedonia, which it occupied, but government leaders faced stiff opposition to the deportation of native Bulgarian Jews, who were regarded as fellow citizens.

Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS), and later chief of the German police. By July 1933, German concentration camps (Konzentrationslager in German, or KZ) held some 27,000 people in “protective custody.” Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength.
The Diary of a Young Girl, also known as The Diary of Anne Frank, journal by Anne Frank, a Jewish teenager who chronicled her family’s two years (1942–44) in hiding during the German occupation of the Netherlands during World War II. The book was first published in 1947—two years after Anne’s death in a concentration camp—and later became a classic of war literature.
In 2010, the Culpeper County, Virginia school system banned the 50th Anniversary "Definitive Edition" of Anne Frank: The Diary of a Young Girl, due to "complaints about its sexual content and homosexual themes."[49] This version "includes passages previously excluded from the widely read original edition.... Some of the extra passages detail her emerging sexual desires; others include unflattering descriptions of her mother and other people living together."[50] After consideration, it was decided a copy of the newer version would remain in the library and classes would revert to using the older version.
Many German and Austrian Jews now attempted to flee Hitler's Reich. However, most Western countries maintained strict immigration quotas and showed little interest in receiving large numbers of Jewish refugees. This was exemplified by the plight of the St. Louis, a ship crowded with 930 Jews that was turned away by Cuba, the United States and other countries and returned back to Europe, soon to be under Hitler's control.

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]
Historians increasingly view the Holocaust as a pan-European phenomenon, or a series of holocausts impossible to conduct without the help of local collaborators.[47] Over 200,000 people are estimated to have been Holocaust perpetrators;[48] without them, the Germans would not have been able to extend the Holocaust across most of Europe.[49] Some Christian churches tried to defend the Jews by declaring that converted Jews were "part of the flock," according to Saul Friedländer, "but even then only up to a point". Otherwise, Friedländer writes, "[n]ot one social group, not one religious community, not one scholarly institution or professional association in Germany and throughout Europe declared its solidarity with the Jews."[50]
Another survivor of Auschwitz-Birkenau was Regina Bialek, a Polish political prisoner, who was saved from the gas chamber at the last moment by Dr. Josef Mengele. Bialek gave a deposition which was entered into the British Trial of Josef Kramer and Forty-Four Others, also known as The Belsen Trial, which took place in 1945 after the end of World War II. According to Bialek's testimony, the gassing of the Jews at Birkenau did not stop, even on Christmas day.
Often, reading Anne Frank's diary is the way in which young people first learn about the horrors of the Nazi genocide. Just as importantly, young readers understand that these crimes were visited upon a girl much like themselves and their friends -- a girl who was often in conflict with her mother, a girl who kept vowing to be a more patient and forgiving person, a girl who fell in love for the first time. A girl who wanted to be a writer -- and who was one.
'Righteous Gentiles' is the phrase used for those non-Jews who risked their lives to save Jews during the Holocaust. At Yad Vashem Museum in Jerusalem, over 11,000 'Righteous Gentiles' are honored; almost 5,000 are Polish. What follows are profiles and oral histories of ten Polish rescuers of Jews. Their stories reveal what transforms people from indifferent bystanders into heroic saviors

Similarly, in Ordinary Men (1992), Christopher Browning examined the deeds of German Reserve Police Battalion 101 of the Ordnungspolizei ("order police"), used to commit massacres and round-ups of Jews, as well as mass deportations to the death camps. The members of the battalion were middle-aged men of working-class background from Hamburg, who were too old for regular military duty. They were given no special training. During the murder of 1,500 Jews from Józefów in Poland, their commander allowed them to opt out of direct participation. Fewer than 12 men out of a battalion of 500 did so. Influenced by the Milgram experiment on obedience, Browning argued that the men killed out of peer pressure, not bloodlust.[471]

In January 1933, after a bitter ten-year political struggle, Adolf Hitler came to power in Germany. During his rise to power, Hitler had repeatedly blamed the Jews for Germany's defeat in World War I and subsequent economic hardships. Hitler also put forward racial theories asserting that Germans with fair skin, blond hair and blue eyes were the supreme form of human, or master race. The Jews, according to Hitler, were the racial opposite, and were actively engaged in an international conspiracy to keep this master race from assuming its rightful position as rulers of the world.

During his time at Auschwitz, Josef Mengele was not the only physician there. It is popularly believed that he was the highest-ranking physician at the camp. This is not the case. That “distinction” belonged to SS captain Dr. Eduard Wirths. Wirths’ position as garrison physician made him responsible in all medical matters for the entire camp complex.
In contemplating a dramatization and pledging no compromise, Levin told Frank he would do it “tenderly and with utmost fidelity.” He was clear about what he meant by fidelity. In his eyes the diary was conscious testimony to Jewish faith and suffering; and it was this, and this nearly alone, that defined for him its psychological, historical, and metaphysical genuineness, and its significance for the world. With these convictions foremost, Levin went in search of a theatrical producer. At the same time, he was unflagging in pressing for publication; but the work was meanwhile slowly gaining independent notice. Janet Flanner, in her “Letter from Paris” in The New Yorker of November 11, 1950, noted the French publication of a book by “a precocious, talented little Frankfurt Jewess”—apparently oblivious of the unpleasant echoes, post-Hitler, of “Jewess.” Sixteen English language publishers on both sides of the Atlantic had already rejected the diary when Levin succeeded in placing it with Valentine Mitchell, a London firm. His negotiations with a Boston house were still incomplete when Doubleday came forward to secure publication rights directly from Frank. Relations between Levin and Frank were, as usual, warm; Frank repeatedly thanked Levin for his efforts to further the fortunes of the diary, and Levin continued under the impression that Frank would support him as the playwright of choice.
Today, I am going to refer quite frankly to a very grave chapter. We can mention it now among ourselves quite openly and yet we shall never talk about it in public. I'm referring to the evacuation of the Jews, the extermination of the Jewish people. Most of you will know what it's like to see 100 corpses side by side or 500 corpses or 1,000 of them. To have coped with this and—except for cases of human weakness—to have remained decent, that has made us tough. This is an unwritten—never to be written—and yet glorious page in our history.[127]
Resistance movements also helped Jews. Sometimes, this aid was intended to help the Jews; often it was rendered in the context of the general anti-Nazi resistance. In Yugoslavia, Serbian partisans attacked a concentration camp near Nish in 1941, freeing a small number of Jews. On April 19, 1943, the Committee for Jewish Defense, aided by Christian railroad workers, attacked a Belgian transport leaving Malines for Auschwitz. Several hundred Jewish deportees escaped with the help of the Belgian resistance.
Cesarani notes that by 1943, as the military position of the German forces deteriorated, the Nazi leadership became more openly explicit about the Final Solution. In March, Goebbels confided to his diary: "On the Jewish question especially, we are in it so deeply that there is no getting out any longer. And that is a good thing. Experience teaches that a movement and a people who have burned their bridges fight with much greater determination and fewer constraints than those that have a chance of retreat."[127]
Many gentile rescuers of Jews appear to have been characterized by six interdependent features: (1) individuality or separateness—an inability to blend well into their social environments; (2) independence or self-reliance—a willingness to act in accordance with personal convictions, regardless of how their actions were viewed by others; (3) an enduring commitment to stand up for the needy that expressed itself in a history of doing good deeds; (4) a tendency to perceive aid to Jews in a matter-of-fact, unassuming way, as neither heroic nor extraordinary; (5) a propensity to save Jews through unplanned and unpremeditated acts, which were performed even impulsively; and (6) a universalistic perception of Jews that defined them not as Jews but as helpless beings, totally dependent on the protection of others.
In the first phase of the experiments, pairs of twins and persons with inherited anomalies were put at the disposal of Dr. Mengele and subjected to all imaginable specialist medical examinations. They were also photographed, plaster casts were made of their jaws and teeth, and they were toe- and fingerprinted. As soon as these examinations were finished, they were killed with lethal injections of phenol to the heart so that the next phase of the experimentation could begin: autopsies and the comparative analysis of their internal organs.

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]

"... Believe me, I'd like to listen, but it doesn't work, because if I'm quiet and serious, everyone thinks I'm putting on a new act and I have to save myself with a joke, and then I'm not even talking about my own family, who assume I must be ill, stuff me with aspirins and sedatives, feel my neck and forehead to see if I have a temperature, ask about my bowel movements and berate me for being in a bad mood, until I just can't keep it up any more, because when everybody starts hovering over me, I get cross, then sad, and finally end up turning my heart inside out, the bad part on the outside and the good part on the inside, and keep trying to find a way to become what I'd like to be and what I could be if ... if only there were no other people in the world."
There were setbacks. In March, the diggers discovered they were tunneling in the direction of a burial pit and were forced to reroute the passageway, losing days in the process. Not long afterward, Dogim was on burial pit duty when he unearthed the bodies of his wife, mother and two sisters. Every member of the Burning Brigade lived with the knowledge that some of the corpses he was helping to burn belonged to family members. And yet to see one’s wife lying in the pit was something else entirely, and Dogim was consumed with sadness and fury. “[He] said he had a knife, that he was going to stab and kill the Sturmbannführer,” Farber later recalled. Farber told Dogim that he was thinking selfishly—even if he succeeded, the rest of the prisoners would be killed in retribution.

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.
In most ghettos, Nazis ordered the Jews to establish a Judenrat (Jewish council) to administer Nazi demands and to regulate the internal life of the ghetto. The Nazis routinely ordered deportations from the ghettos. In some of the large ghettos, 1,000 people per day were sent by rail to concentration and extermination camps. To get them to cooperate, the Nazis told the Jews they were being transported elsewhere for labor.
Responding with alarm to Hitler’s rise, the Jewish community sought to defend their rights as Germans. For those Jews who felt themselves fully German and who had patriotically fought in World War I, the Nazification of German society was especially painful. Zionist activity intensified. “Wear it with pride,” journalist Robert Weltsch wrote in 1933 of the Jewish identity the Nazis had so stigmatized. Religious philosopher Martin Buber led an effort at Jewish adult education, preparing the community for the long journey ahead. Rabbi Leo Baeck circulated a prayer for Yom Kippur (the Day of Atonement) in 1935 that instructed Jews on how to behave: “We bow down before God; we stand erect before man.” Yet while few, if any, could foresee its eventual outcome, the Jewish condition was increasingly perilous and was expected to worsen.
As of 1 January 2006, Yad Vashem had recognized 21,310 persons as Righteous Gentiles. Poles formed the largest group, with 5,941 having been recognized. Other East Europeans came from Ukraine (2,139), Hungary (671), Lithuania (630), Belarus (564), Slovakia (460), Russia (120), Czech Republic (115), Latvia (100), Moldova (71), Romania (52), and Estonia (3). Yad Vashem cautions, however, that its figures do not represent the actual number of people who rescued Jews in each country. For example, gentiles who saved Jews for financial gain are excluded. Thus many more people rescued Jews than are officially recognized. Because Poles constitute by far the largest group of Righteous Gentiles, they have been the most extensively studied, and most of the following observations are based on data concerning them.
Man blinded by continuous beatings  © The ideas and emotions that lay behind the Holocaust were not new, nor were they uniquely German. The Nazis were the heirs of a centuries-old tradition of Jew-hatred, rooted in religious rivalry and found in all European countries. When the Nazis came to carry out their genocidal programme, they found collaborators in all the countries they dominated, including governments that enjoyed considerable public support. Most people drew the line at mass murder, but relatively few could be found to oppose it actively or to extend help to the Jews.

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.
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]
