Peterson, who is researching the long history of the Rivesaltes camp, also told me that the camp remained more or less in operation from 1939 through 1967 and then after 1985. Prisoners and refugees after the war included POWs, collaborators, Algerians and, in the 1980s, migrants waiting to be expelled from the country. The French government did little in the meantime to improve facilities from their wartime conditions.
On August 4, 1944, the Gestapo (German Secret State Police) discovered the hiding place. It has been long thought that the authorities acted after being tipped off by an anonymous Dutch caller. But a more recent theory is that the German SD discovered the hiding place by chance, while investigating reports that illegal work and fraud with ration coupons were occurring at the house.

According to the famous philosopher and political theorist, Hannah Arendt, the allure of Nazism as a totalitarian ideology (with its attendant mobilisation of the German population) resided within the construct of helping that society deal with the cognitive dissonance resultant from the tragic interruption of the First World War and the economic and material suffering consequent to the Depression and brought to order the revolutionary unrest occurring all around them. Instead of the plurality that existed in democratic or parliamentary states, Nazism as a totalitarian system promulgated "clear" solutions to the historical problems faced by Germany, levied support by de-legitimizing the former government of Weimar and provided a politico-biological pathway to a better future, one free from the uncertainty of the past. It was the atomised and disaffected masses that Hitler and the party elite pointed in a particular direction and using clever propaganda to make them into ideological adherents, exploited in bringing Nazism to life.[275]
German doctors performed a variety of experiments on prisoners at Auschwitz. SS doctors tested the efficacy of X-rays as a sterilization device by administering large doses to female prisoners. Carl Clauberg injected chemicals into women's uteruses in an effort to glue them shut. Prisoners were infected with spotted fever for vaccination research and exposed to toxic substances to study the effects.[125] In one experiment Bayer, then part of IG Farben, paid RM 150 each for 150 female inmates from Auschwitz (the camp had asked for RM 200 per woman), who were transferred to a Bayer facility to test an anesthetic. A Bayer employee wrote to Rudolf Höss: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price." The Bayer research was led at Auschwitz by Helmuth Vetter of Bayer/IG Farben, who was also an Auschwitz physician and SS captain, and by Auschwitz physicians Friedrich Entress and Eduard Wirths.[126]

Estimates of the total German war dead range from 5.5 to 6.9 million persons.[149] A study by German historian Rüdiger Overmans puts the number of German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders.[150] Richard Overy estimated in 2014 that about 353,000 civilians were killed in Allied air raids.[151] Other civilian deaths include 300,000 Germans (including Jews) who were victims of Nazi political, racial, and religious persecution[152] and 200,000 who were murdered in the Nazi euthanasia program.[153] Political courts called Sondergerichte sentenced some 12,000 members of the German resistance to death, and civil courts sentenced an additional 40,000 Germans.[154] Mass rapes of German women also took place.[155]

These people had a blue stamp in their registration cards, meaning that they were exempt from deportation. They were Jews who had British or American citizenship. The Nazis saw these Jews as ‘exchange Jews’, and they would attempt to exchange each one of them for five to 10 Germans; especially military prisoners of war. In fact, few exchanges ever occurred.
Things continued to get worse. The Germans began to require all Jewish people to wear yellow stars on their clothing. Some Jews were rounded up and taken to concentration camps. Then one day the order came that Margot would have to go to a labor camp. Otto was not going to let that happen. He and Edith had been preparing a place for the family to hide. The girls were told to pack up what they could. They had to wear all their clothes in layers because a suitcase would look too suspicious. Then they went to their hiding place.

The most pressing economic matter the Nazis initially faced was the 30 percent national unemployment rate.[251] Economist Dr. Hjalmar Schacht, President of the Reichsbank and Minister of Economics, created a scheme for deficit financing in May 1933. Capital projects were paid for with the issuance of promissory notes called Mefo bills. When the notes were presented for payment, the Reichsbank printed money. Hitler and his economic team expected that the upcoming territorial expansion would provide the means of repaying the soaring national debt.[252] Schacht's administration achieved a rapid decline in the unemployment rate, the largest of any country during the Great Depression.[251] Economic recovery was uneven, with reduced hours of work and erratic availability of necessities, leading to disenchantment with the regime as early as 1934.[253]

After the war, the Allies occupied Germany, outlawed the Nazi Party and worked to purge its influence from every aspect of German life. The party’s swastika flag quickly became a symbol of evil in modern postwar culture. Although Hitler killed himself before he could be brought to justice, a number of Nazi officials were convicted of war crimes in the Nuremberg trials, which took place in Nuremberg, Germany, from 1945 to 1949.

Memory is not something that is acquired once and stays on forever. The moment that the last eyewitnesses and survivors pass away, we have to work together to build on that which remains: the testimonies of those former prisoners and the authentic artifacts connected with Auschwitz. Each item can have its own enormous meaning and should find its place in the collection of the Auschwitz Memorial. Here, it will be preserved, studied, and displayed. Its place is here. 
By 1940, the CCI came under the control of the Verwaltung und Wirtschaftshauptamt Hauptamt (VuWHA; Administration and Business office) which was set up under Oswald Pohl.[25] Then in 1942, the CCI became Amt D (Office D) of the consolidated main office known as the SS-Wirtschafts-Verwaltungshauptamt (SS Economic and Administrative Department; WVHA) under Pohl.[25] In 1942, the SS built a network of extermination camps to systematically kill millions of prisoners by gassing. The extermination camps (Vernichtungslager) and death camps (Todeslager) were camps whose primary function was genocide. The Nazis themselves distinguished the concentration camps from the extermination camps.[26][27] The British intelligence service had information about the concentration camps, and in 1942 Jan Karski delivered a thorough eyewitness account to the government.
