According to testimony given at the Nuremberg IMT, approximately 150 Dachau inmates were forced to participate in medical experiments conducted by Dr. Sigmund Rascher for the German Air Force, and about half of them died as a result. The subjects for these experiments were allegedly German "professional criminals" and Soviet POWs who were Communist Commissars, sentenced to be executed on the orders of Adolf Hitler. One Jew, who had been condemned to death for breaking the law against race mixing, was used in these experiments.
What you will see here is the final and utter condemnation of the Nazi party. It justifies every measure the United Nations will take to exterminate that party. What you will see here is such a disgrace to the German people that their names must be erased from the list of civilized nations [...] It is your lot to begin the hard task of restoring the name of the German people [...] But this cannot be done until you have reared a new generation amongst whom it is impossible to find people prepared to commit such crimes; until you have reared a new generation possessing the instinctive good will to prevent a repetition of such horrible cruelties. We will now begin our tour.
Bergen-Belsen [ˈbɛʁɡn̩.bɛlsn̩], or Belsen, was a Nazi concentration camp in what is today Lower Saxony in northern Germany, southwest of the town of Bergen near Celle. Originally established as a prisoner of war camp, in 1943, parts of it became a concentration camp. Initially this was an "exchange camp", where Jewish hostages were held with the intention of exchanging them for German prisoners of war held overseas. The camp was later expanded to accommodate Jews from other concentration camps.
