Nazi human experimentation in the context of "Victims of Nazi Germany"

The Holocaust (/ˈhɒləkɔːst/ HOL-ə-kawst), known in Hebrew as the Shoah (/ˈʃoʊə/ SHOH-ə; Hebrew: שּׁוֹאָה, romanized: Shoah, IPA: [ʃoˈʔa], lit. 'Catastrophe'), was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. Separate Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups.

The Nazis developed their ideology based on racism and pursuit of "living space", and seized power in early 1933. Meant to force all German Jews to emigrate, regardless of means, the regime passed anti-Jewish laws, encouraged harassment, and orchestrated a nationwide pogrom known as Kristallnacht in November 1938. After Germany's invasion of Poland in September 1939, occupation authorities began to establish ghettos to segregate Jews. Following the June 1941 invasion of the Soviet Union, 1.5 to 2 million Jews were shot by German forces and local collaborators. By early 1942, the Nazis decided to murder all Jews in Europe. Victims were deported to extermination camps where those who had survived the trip were killed with poisonous gas, while others were sent to forced labor camps where many died from starvation, abuse, exhaustion, or being used as test subjects in experiments. Property belonging to murdered Jews was redistributed to the German occupiers and other non-Jews. Although the majority of Holocaust victims died in 1942, the killing continued until the end of the war in 1945.

Josef Mengele (German: [ˈjoːzɛf ˈmɛŋələ] ; 16 March 1911 – 7 February 1979), often dubbed the "Angel of Death" (German: Todesengel), was a Nazi German Schutzstaffel (SS) officer and physician during World War II at the Soviet front and then at Auschwitz during the Holocaust. He conducted research and experiments on prisoners at the Auschwitz II-Birkenau concentration camp, where he was a member of the team of doctors who selected victims to be murdered in the gas chambers.

Before the war, Mengele received doctorates in anthropology and medicine, and he began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943. He was assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. With Red Army troops sweeping through German-occupied Poland, Mengele was transferred 280 kilometres (170 miles) away from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, ten days before the arrival of the Soviet forces at Auschwitz.

During World War II, around 200,000 ethnic Polish children as well as an unknown number of children of other Slavic ethnicities from the Soviet Union were abducted from their homes and forcibly transported to Nazi Germany for purposes of forced labour, medical experimentation, or Germanization. This was among the most notable Nazi crimes against children.

An aim of the project was to acquire and "Germanize" children believed to have Aryan/Nordic traits because Nazi officials believed that they were the descendants of German settlers who had emigrated to Poland or the Soviet Union. Those labelled "racially valuable" (gutrassig) were forcibly assimilated in centres and then forcibly adopted to German families and SS Home Schools.

Unethical human experimentation is human experimentation that violates the principles of medical ethics. Such practices have included denying patients the right to informed consent, using pseudoscientific frameworks such as race science, and torturing people under the guise of research. Around World War II, Imperial Japan and Nazi Germany carried out brutal experiments on prisoners and civilians through groups like Unit 731 or individuals like Josef Mengele; the Nuremberg Code was developed after the war in response to the Nazi experiments. Countries have carried out brutal experiments on marginalized populations. Examples include American abuses during Project MKUltra and the Tuskegee syphilis experiments, and the mistreatment of indigenous populations in Canada and Australia. The Declaration of Helsinki, developed by the World Medical Association, is widely regarded as the cornerstone document on human research ethics.

United States of America v. Karl Brandt, et al., commonly known as the Doctors' Trial, was the first of the twelve "Subsequent Nuremberg trials" for war crimes and crimes against humanity after the end of World War II between 1946 and 1947. The accused were 20 physicians and 3 SS officials charged for their involvement in the Aktion T4 programme and Nazi human experimentation.

The Doctors' Trial was held by United States authorities at the Palace of Justice in Nuremberg in the American occupation zone before US military courts, not before the International Military Tribunal. Seven of the accused were sentenced to death by hanging, five were sentenced to life imprisonment, four were given prison sentences from 10 to 20 years, and seven were acquitted.

Ravensbrück (German: [ˌʁaːvn̩sˈbʁʏk]) was a Nazi Germany concentration camp exclusively for women from 1939 to 1945, located in northern Germany, 90 km (56 mi) north of Berlin at a site near the village of Ravensbrück (part of Fürstenberg/Havel). The camp memorial's estimated figure of 132,000 women who were in the camp during the war includes about 48,500 from Poland, 28,000 from the Soviet Union, almost 24,000 from Germany and Austria, nearly 8,000 from France, almost 2,000 from Belgium, and thousands from other countries including a few from the United Kingdom and the United States. More than 20,000 (15 percent) of the total were Jewish. More than 80 percent were political prisoners. Many prisoners were employed as slave laborers by Siemens & Halske. From 1942 to 1945, the Nazis undertook medical experiments on Ravensbrück prisoners to test the effectiveness of sulfonamides.

In the spring of 1941, the SS established a small adjacent camp for male inmates, who built and managed the camp's gas chambers in January 1945. Of the female prisoners who passed through the Ravensbrück camp, about 50,000 perished. No precise accounting for the number of prisoners murdered in the gas-chamber at Ravensbrück can be given, but a compilation of witness accounts suggests that the number was over 5,000 and the true figure may have been much higher.
