Ms. Jastrzebiowska’s husband, Andrzej Jastrzebiowski, 38, is a metal conservator. He spent three months cleaning all the eyeglasses in a vitrine, preserving their distressed state but trying to prevent them from corroding further. “When I saw the eyeglasses in the exhibition, I saw it as one big pile,” he said. But in the lab, he began to examine them one by one. One had a screw replaced by a bent needle; another had a repaired temple. “And then this enormous mass of glasses started becoming people,” Mr. Jastrzebiowski said. This “search for the individual,” he said, helps ensure that the work does not become too routine.

At the bottom of the K.L. hierarchy, even below the criminals, were the Jews. Today, the words “concentration camp” immediately summon up the idea of the Holocaust, the genocide of European Jews by the Nazis; and we tend to think of the camps as the primary sites of that genocide. In fact, as Wachsmann writes, as late as 1942 “Jews made up fewer than five thousand of the eighty thousand KL inmates.” There had been a temporary spike in the Jewish inmate population in November, 1938, after Kristallnacht, when the Nazis rounded up tens of thousands of Jewish men. But, for most of the camps’ first decade, Jewish prisoners had usually been sent there not for their religion, per se, but for specific offenses, such as political dissent or illicit sexual relations with an Aryan. Once there, however, they found themselves subject to special torments, ranging from running a gantlet of truncheons to heavy labor, like rock-breaking. As the chief enemies in the Nazi imagination, Jews were also the natural targets for spontaneous S.S. violence—blows, kicks, attacks by savage dogs.
In 1983, French scholar George Wellers was one of the first to use German data on deportations; he arrived at a figure of 1,471,595 deaths, including 1.35 million Jews and 86,675 Poles.[191] A larger study in the late 1980s by Franciszek Piper, published by Yad Vashem in 1991,[192] used timetables of train arrivals combined with deportation records to calculate that, of the 1.3 million deported to the camp, 1,082,000 died there between 1940 and 1945, a figure (rounded up to 1.1 million) that he regarded as a minimum[193] and that came to be widely accepted.[e]
In September 1933, an important policy document known as the Prussian Memorandum began circulating among lawmakers and jurists of the Third Reich. The Nazi regime was still in its infancy; Hitler had been named chancellor just nine months prior, the result of a power-sharing arrangement with nationalist conservatives who thought they could control the mercurial Austrian. Following the Reichstag Fire in February of that year, Hitler had assumed emergency powers and within weeks usurped the authority of the parliament. By that critical autumn, the Third Reich had begun Nazifying the German legal code. The Prussian Memorandum that passed between Nazi legal hands was an early blueprint for the 1935 Nuremberg Laws, which stripped Jews of their citizenship and criminalized sexual relations between Germans and those thought to have impure blood. It was the foundational text of Nazi legal thinking. Incredibly, the Prussian Memorandum expressly cited the gold standard of racist lawmaking at the time: the United States of America.
A place for assembling and confining political prisoners and enemies of a nation. Concentration camps are particularly associated with the rule of the Nazis in Germany, who used them to confine millions of Jews (see also Jews) as a group to be purged from the German nation. Communists, Gypsies, homosexuals, and other persons considered undesirable according to Nazi principles, or who opposed the government, were also placed in concentration camps and eventually executed in large groups. (See Holocaust.)

Hitler admired the British Empire and its colonial system as living proof of Germanic superiority over 'inferior' races and saw United Kingdom as Germany's natural ally.[59][60] He wrote in Mein Kampf: "For a long time to come there will be only two Powers in Europe with which it may be possible for Germany to conclude an alliance. These Powers are Great Britain and Italy."[60]
Next to physical labor, military drill played an important part, especially for the older men. Still to-day I can hear the command: 'Eyes right! Eyes front!' The drill consisted mainly of marching in large formations and in turns and practising the salute—a quick removal of the cap. Those who did not greet a passing S.S. man with this procedure laid themselves open to severe punishment. A sixty-five-year-old lawyer, who in spite of glasses could see very little, did not salute a passing 'superior officer,' and was struck so that his glasses were broken. His excuse that he was extremely nearsighted was answered with curses.
In May 14, 1940, the Netherlands surrendered to Germany after the bombing of Rotterdam, having being invaded just five days earlier. The following month, Anne turned 10. The restrictions and persecution the Franks had faced in Germany were brought to their new home. Otto transferred control of his businesses to trusted colleagues to make the business appear Aryan-owned and to avoid having to register it with the German authorities. The family had to register as Jews with the German authorities in January 1942 and all Dutch Jews were ordered to Amsterdam.
As far as we could see, there was no possibility in camp for any religious services. Sundays are workdays for the inmates. Among the Jewish prisoners the rabbis were treated especially badly. Officially the fight against religious affiliations is not admitted, but as a matter of fact National Socialism is no less antireligious than Bolshevism, with the only difference that it has not yet developed quite so far in the amalgamation of political and religious ideologies.
Adolf Hitler, the leader of Nazi Germany, wrote a book called Mein Kampf ("My Struggle"). The book said that all of Germany's problems happened because Jews were making plans to hurt the country. He also said that Jewish and communist politicians planned the Armistice of 1918 that ended World War I, and allowed Germany to agree to pay huge amounts of money and goods (reparations).
During the Holocaust, concentration camp prisoners received tattoos only at one location, Auschwitz. Incoming prisoners were assigned a camp serial number which was sewn to their prison uniforms. Only those prisoners selected for work were issued serial numbers; those prisoners sent directly to the gas chambers were not registered and received no tattoos.
Hitler denounced the Old Testament as "Satan's Bible" and utilising components of the New Testament he attempted to prove that Jesus was both an Aryan and an antisemite by citing passages such as John 8:44 where he noted that Jesus is yelling at "the Jews", as well as saying to them "your father is the devil" and the Cleansing of the Temple, which describes Jesus' whipping of the "Children of the Devil".[209] Hitler claimed that the New Testament included distortions by Paul the Apostle, who Hitler described as a "mass-murderer turned saint".[209] In their propaganda, the Nazis utilised the writings of Martin Luther, the Protestant Reformer. They publicly displayed an original edition of Luther's On the Jews and their Lies during the annual Nuremberg rallies.[210][211] The Nazis endorsed the pro-Nazi Protestant German Christians organization.
Many of the prisoners died in the concentration camps due to deliberate maltreatment, disease, starvation, and overwork, or they were executed as unfit for labor. Prisoners were transported in inhumane conditions by rail freight cars, in which many died before reaching their final destination. The prisoners were confined in the boxcars for days or even weeks, with little or no food or water. Many died of dehydration in the intense heat of summer or froze to death in winter. Concentration camps also existed in Germany itself, and while they were not specifically designed for systematic extermination, many of their inmates perished because of harsh conditions or they were executed.
