I was imprisoned in the Auschwitz concentration camp from January 1941 to the autumn of 1942 – I was later transferred to the Mauthausen camp, and then to Gusen, where I stayed until 5 May 1945.
Aumeier and Grabner are the only names of the SS men from the Auschwitz camp crew that I recall. I never learned other names, or I no longer remember them. If I were to see all captured criminals from Auschwitz and other subcamps, I could possibly recognize them and say something about them in my testimony.
As for Aumeier, I witnessed him beating prisoners with a riding crop that he always carried around. I saw him attending and observing executions in block 11 with his subordinate Palitzsch. I cannot tell whether he personally shot people, because I never saw it, but I did see Palitzsch shoot. In 1942, Aumeier searched me and found a wooden box in which I carried large needles and buttons. He told me that this was sabotage, destroyed the box, and hit me in the face.
When I got to Auschwitz in 1941, SS men beat me up on Grabner’s orders, breaking three of my ribs and knocking out all of my teeth. Grabner was head of the Political Department, and I learned from fellow prisoners who had contact with him in this capacity that he tortured people during interrogations.
The report was read out.
