Gerstein Report

The Gerstein Report was written in 1945 by Kurt Gerstein, Obersturmführer of the SS-TV, who served as Head of Technical Disinfection Services of the SS during the Second World War and in that capacity supplied a pesticide, based on hydrogen cyanide, Zyklon B, from Degesch (Deutsche Gesellschaft für Schädlingsbekämpfung) to Rudolf Höss in Auschwitz and conducted the negotiations with the owners.^[1]

On 18 August 1942, along with Rolf Günther and Wilhelm Pfannenstiel, Gerstein witnessed the gassing of some 3,000 Jews in the extermination camp of Belzec in occupied Poland. The report features his eyewitness testimony and was used as evidence at the Nuremberg Trials.^[2]: 112

When Gerstein surrendered to the French Commandant in the occupied town of Reutlingen on 22 April 1945, he was sent to the town of Rottweil, where he was placed under "honourable captivity" and was given accommodation in the Hotel Mohren. There, he composed his report first in French and then in German.^{[2]: 211–212}
