Kurt Gerstein

Kurt Gerstein (11 August 1905 – 25 July 1945) was a German SS officer and member of the Institute for Hygiene of the Waffen-SS. He witnessed mass murders in the Nazi extermination camps Belzec and Treblinka. He gave information to the Swedish diplomat Göran von Otter, as well as to members of the Roman Catholic Church with contacts to Pope Pius XII, in an effort to inform the international public about the Holocaust. In 1945, following his surrender, he wrote the Gerstein Report covering his experience of the Holocaust. He died, an alleged suicide, while in French custody.
