At Auschwitz, there was a team of Nazi doctors who conducted experiments, but the two most notorious were Dr. Carl Clauberg and Dr. Josef Mengele. Dr. Clauberg focused his attention on finding ways to sterilize women, by such unorthodox methods as X-rays and injections of various substances into their uteruses. Dr. Mengele experimented on identical twins, hoping to find a secret to cloning what Nazis considered the perfect Aryan.
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]

Nazi society had elements supportive of animal rights and many people were fond of zoos and wildlife.[399] The government took several measures to ensure the protection of animals and the environment. In 1933, the Nazis enacted a stringent animal-protection law that affected what was allowed for medical research.[400] The law was only loosely enforced, and in spite of a ban on vivisection, the Ministry of the Interior readily handed out permits for experiments on animals.[401]
We booked our entry tickets 3 weeks before our arrival in Amsterdam and time choices were already ge...tting limited for our 5 day stay. I had not visited the Anne Frank house since 1977. The experience has changed markedly. The welcome center and interpretive information were very nice. There are short films and interviews with eye witnesses that I have never seen before. It is a must see but recent murders at the synagogue in Pittsburgh impacted my feelings about the visit showing that some things in the world have changed greatly and others not at all. See More
Auschwitz is the generic name given to the cluster of concentration, labour and extermination camps built by the Germans during the Second World War, located outside the town of Oświęcim in Lesser Poland Voivodeship, southern Poland, 65 km (40 mi) west of Kraków. The camps have become a place of pilgrimage for survivors, their families, and all who wish to remember and contemplate the Holocaust. The grounds are a UNESCO World Heritage Site.
In every camp, Allied soldiers encountered appalling scenes. Bergen-Belsen was liberated by British forces on 15 April 1945. It had become exceptionally overcrowded after the arrival of survivors of the death marches. Thousands of unburied bodies lay strewn around the camp, while in the barracks some 60,000 starving and mortally ill people were packed together without food or water. The mortality rate amongst those suffering from typhus was over 60 per cent.
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.

In 1942, after the death of Armaments Minister Fritz Todt, Hitler appointed Albert Speer as his replacement.[274] Wartime rationing of consumer goods led to an increase in personal savings, funds which were in turn lent to the government to support the war effort.[275] By 1944, the war was consuming 75 percent of Germany's gross domestic product, compared to 60 percent in the Soviet Union and 55 percent in Britain.[276] Speer improved production by centralising planning and control, reducing production of consumer goods, and using forced labour and slavery.[277][278] The wartime economy eventually relied heavily upon the large-scale employment of slave labour. Germany imported and enslaved some 12 million people from 20 European countries to work in factories and on farms. Approximately 75 percent were Eastern European.[279] Many were casualties of Allied bombing, as they received poor air raid protection. Poor living conditions led to high rates of sickness, injury, and death, as well as sabotage and criminal activity.[280] The wartime economy also relied upon large-scale robbery, initially through the state seizing the property of Jewish citizens and later by plundering the resources of occupied territories.[281]
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.
