This is not the limit of the horrors of Auschwitz I. It was also the site of disturbing medical experimentation on Jewish and Roma prisoners, including castration, sterilisation and testing how they were affected by contagious diseases. The infamous “Angel of Death”, SS captain Dr Josef Mengele, was one of the physicians practising here. His particular interest was experimenting on twins.

The pictures only came to light 25 years ago and, despite them showing moments from around 45 years before that, they completely captured the entire experience as it had been in my mind all that time. I was dumbfounded and devastated, having had no idea they existed, and I have spent literally hundreds of hours scouring them, trying to find my father and brother. The pictures have reassured me that I was not imagining it all, as I sometimes thought I might have done.

The rise of Nazism in Germany during the 1930s—and the conviction that Hitler could be defeated only by military force—prompted Einstein rethink his strict pacifist views. Increasing numbers of Jewish refugees were fleeing Germany, bringing with them horrific tales of Nazi persecution; Einstein, who was also Jewish, left for the United States in 1932.
The metaphor of war encouraged the inhumanity of the S.S. officers, which they called toughness; licensed physical violence against prisoners; and accounted for the military discipline that made everyday life in the K.L. unbearable. Particularly hated was the roll call, or Appell, which forced inmates to wake before dawn and stand outside, in all weather, to be counted and recounted. The process could go on for hours, Wachsmann writes, during which the S.S. guards were constantly on the move, punishing “infractions such as poor posture and dirty shoes.”
The prisoners' days began at 4:30 am for the men (an hour later in winter), and earlier for the women, when the block supervisor sounded a gong and started beating inmates with sticks to encourage them to wash and use the latrines quickly.[106] Sanitary arrangements were atrocious, with few latrines and a lack of clean water. Each washhouse had to service thousands of prisoners. In sectors BIa and BIb in Auschwitz II-Birkenau, two buildings containing latrines and washrooms were installed in 1943. These contained troughs for washing and 90 faucets; the toilet facilities were "sewage channels" covered by concrete with 58 holes for seating. There were three barracks with washing facilities or toilets to serve 16 residential barracks in BIIa, and six washrooms/latrines for 32 barracks in BIIb, BIIc, BIId, and BIIe.[107] Primo Levi described a 1944 Auschwitz III washroom:
On our arrival at Auschwitz they chased us off the cattle wagon, which stopped right in front of the gate with the sign Arbeit Macht Frei (Work Makes You Free). I thought I was entering a labour camp, but little did I know. They asked me my profession, and I said painter as I’d picked up the advice en route to say something practical and useful. If I’d said I’d just finished high school they’d have sent me straight to the gas chambers.

Aware that as witnesses to the killings they would eventually be killed themselves, the Sonderkommandos of Birkenau Kommando III staged an uprising on 7 October 1944, following an announcement that some of them would be selected to be "transferred to another camp"—a common Nazi ruse for the murder of prisoners.[229][230] They attacked the SS guards with stones, axes, and makeshift hand grenades, which they also used to damage Crematorium IV and set it on fire. As the SS set up machine guns to attack the prisoners in Crematorium IV, the Sonderkommandos in Crematorium II also revolted, some of them managing to escape the compound.[230][231] The rebellion was suppressed by nightfall.[232]
Although the Nazis won the greatest share of the popular vote in the two Reichstag general elections of 1932, they did not have a majority. Hitler therefore led a short-lived coalition government formed with the German National People's Party.[14] Under pressure from politicians, industrialists, and the business community, President Paul von Hindenburg appointed Hitler as Chancellor of Germany on 30 January 1933. This event is known as the Machtergreifung ("seizure of power").[15]

The release took almost twelve hours, during which we had to stand in line waiting in the open air, without food. Part of the release ceremonies was the address of an S.S. man. He called our attention to the fact that we were forbidden to tell anything that we had seen in the camp. Although we all had to fill in a form of this nature, I cannot recognize an obligation in this respect, not only because it was forced, but also because it was imposed by a party that habitually does not keep its promises.

In early 1942, at the Wannsee Conference near Berlin, the Nazi Party decided on the last phase of what it called the “Final Solution” of the “Jewish problem” and spelled out plans for the systematic murder of all European Jews. In 1942 and 1943, Jews in the western occupied countries including France and Belgium were deported by the thousands to the death camps mushrooming across Europe. In Poland, huge death camps such as Auschwitz began operating with ruthless efficiency. The murder of Jews in German-occupied lands stopped only in last months of the war, as the German armies were retreating toward Berlin. By the time Hitler committed suicide in April 1945, some 6 million Jews had died.
At some point during her induction, Lasker-Wallfisch mentioned she played the cello. “That is fantastic,” the inmate processing her said. “You will be saved.” The Birkenau women’s orchestra, responsible for keeping prisoners in step as they marched to work assignments, needed a cellist. “It was a complete coincidence,” Lasker-Wallfisch said, shaking her head. “The whole thing was complete insanity from beginning to end.”
When the Nazis seized power in 1933, roughly 67 percent of the population of Germany was Protestant, 33 percent was Roman Catholic, while Jews made up less than 1 percent.[405][406] According to 1939 census, 54 percent considered themselves Protestant, 40 percent Roman Catholic, 3.5 percent Gottgläubig (God-believing; a Nazi religious movement) and 1.5 percent nonreligious.[407]
Created by the Government of Poland in 1947 at the request of survivors, the Auschwitz-Birkenau State Museum comprises almost 472 acres (191 hectares) and was declared a World Heritage Site by UNESCO in 1979. The Memorial today consists of Collections, Archives, a research, education, conservation and publishing center. Millions of people have visited the complex to learn its crucial significance, honor survivors and victims, and carry forward the memory of Auschwitz and the Holocaust.

The Nazis were initially very hostile to Catholics because most Catholics supported the German Centre Party. Catholics opposed the Nazis' promotion of compulsory sterilization of those whom they deemed inferior and the Catholic Church forbade its members to vote for the Nazis. In 1933, extensive Nazi violence occurred against Catholics due to their association with the Centre Party and their opposition to the Nazi regime's sterilization laws.[212] The Nazis demanded that Catholics declare their loyalty to the German state.[213] In their propaganda, the Nazis used elements of Germany's Catholic history, in particular the German Catholic Teutonic Knights and their campaigns in Eastern Europe. The Nazis identified them as "sentinels" in the East against "Slavic chaos", though beyond that symbolism, the influence of the Teutonic Knights on Nazism was limited.[214] Hitler also admitted that the Nazis' night rallies were inspired by the Catholic rituals which he had witnessed during his Catholic upbringing.[215] The Nazis did seek official reconciliation with the Catholic Church and they endorsed the creation of the pro-Nazi Catholic Kreuz und Adler, an organization which advocated a form of national Catholicism that would reconcile the Catholic Church's beliefs with Nazism.[213] On 20 July 1933, a concordat (Reichskonkordat) was signed between Nazi Germany and the Catholic Church, which in exchange for acceptance of the Catholic Church in Germany required German Catholics to be loyal to the German state. The Catholic Church then ended its ban on members supporting the Nazi Party.[213]
At this time only the main camp, later known as Auschwitz I, had been established. Himmler ordered the construction of a second camp for 100,000 inmates on the site of the village of Brzezinka, roughly two miles from the main camp. This second camp, now known as Birkenau or Auschwitz II, was initially intended to be filled with captured Russian POWs who would provide the slave labor to build the SS “utopia” in Upper Silesia. Chemical giant I G Farben expressed an interest in utilizing this labor force, and extensive construction work began in October 1941 under terrible conditions and with massive loss of life. About 10,000 Russian POWs died in this process. The greater part of the apparatus of mass extermination was eventually built in the Birkenau camp and the majority of the victims were murdered here.

In early February, the Polish Red Cross hospital opened in blocks 14, 21, and 22 at Auschwitz I, headed by Dr. Józef Bellert and staffed by 30 volunteer doctors and nurses from Kraków, along with around 90 former inmates. The critically injured patients—estimated at several thousands—were relocated from Birkenau and Monowitz to the main camp. Some orphaned children were adopted by Oświęcim residents, while others were transferred to Kraków, where several were adopted by Polish families, or placed in an orphanage at Harbutowice.[254] The hospital cared for more than 4,500 patients (most of them Jews) from 20 countries, suffering from starvation, alimentary dystrophy, gangrene, necrosis, internal haemorrhaging, and typhoid fever. At least 500 died. Assistance was provided by volunteers from Oświęcim and Brzeszcze, who donated money and food, cleaned hospital rooms, delivered water, washed patients, cooked meals, buried the dead, and transported the sick in horse-drawn carts between locations. Securing enough food for thousands of former prisoners was a constant challenge. The hospital director personally went from village to village to collect milk.[254]
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.
Germany's war in the East was based on Hitler's long-standing view that Jews were the great enemy of the German people and that Lebensraum was needed for Germany's expansion. Hitler focused his attention on Eastern Europe, aiming to conquer Poland and the Soviet Union.[182][183] After the occupation of Poland in 1939, all Jews living in the General Government were confined to ghettos, and those who were physically fit were required to perform compulsory labour.[317] In 1941 Hitler decided to destroy the Polish nation completely; within 15 to 20 years the General Government was to be cleared of ethnic Poles and resettled by German colonists.[318] About 3.8 to 4 million Poles would remain as slaves,[319] part of a slave labour force of 14 million the Nazis intended to create using citizens of conquered nations.[183][320]
The camps were liberated by the Allied forces between 1944 and 1945. The first major camp, Majdanek, was discovered by the advancing Soviets on July 23, 1944. Auschwitz was liberated, also by the Soviets, on January 27, 1945; Buchenwald by the Americans on April 11; Bergen-Belsen by the British on April 15; Dachau by the Americans on April 29; Ravensbrück by the Soviets on the same day; Mauthausen by the Americans on May 5; and Theresienstadt by the Soviets on May 8.[42] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Nazis in 1943. Colonel William W. Quinn of the U.S. 7th Army said of Dachau: "There our troops found sights, sounds, and stenches horrible beyond belief, cruelties so enormous as to be incomprehensible to the normal mind."[43][44]
