I was imprisoned at Auschwitz between 24 or 26 June 1942 and 4 July 1944. My prison number was 654. Initially, I worked at the Unterkunftskammer [clothing storeroom], and then I spent three months at the so-called Kommandentur Reiniger as a patient. Finally, on 9 May 1944, I started to work at the German armament plant (Deutsche Ausrüstungswerke, DAW). From among the defendants, I remember the following persons: Kurt Müller, a Blockführer at the main camp in the rank of SS-Unterscharführer. He was violent toward prisoners; he shoved them and beat them, as if in fun. I know Artur Breitwieser from his stint at the Unterkunftskammer [accommodation chamber]. Most recently, he served in the rank of Unterscharführer. He was a martinet, who watched prisoners closely and denounced them. I witnessed as he beat prisoners on their faces. SS-Obersturmführer Josten was often on duty at the gate when working kommandos [work details] marched to labor. Typically, he assisted the then Schutzhaftlagerführer [camp leader] Aumeier. He harassed prisoners in the process and beat them and kicked them if they were marching in uneven rows. He did the same if someone held their cap improperly or was guilty of some similar misdemeanor. I know SS-Hauptscharführer Nebbe as a clerk [?] for the staff company of the headquarters, from the time I spent working at the headquarters as an orderly. He supervised our work. He would brush his hand across the floor under cupboards to check if dust had been wiped off properly and he beat prisoners on their faces for the slightest negligence. As an orderly, I also cleaned the room where, among others, Schumacher lived. At that time, he was serving in the rank of Rottenführer, later he was promoted at Auschwitz to the rank of Unterscharführer. When he saw that I was hungry, he threw me some bread, as if I was a dog. When he was unhappy with my work, he called me names. Later, he worked at the food store room, where he beat prisoners who were busy loading bread.
The report was read out. At this point the interview and the report were concluded.
