I was interned at the Auschwitz camp between 4 April 1941 and the end of October 1944. Over this entire period, I was at the Auschwitz I camp.
I met suspect Kurt Müller in 1941, alternatively in 1942; he was discharging the duties of Blockführer and later even of Arbeitsdienstführer [work service leader]. Already at that time, I knew the suspect by name. They said he was a reverend. In 1942 and at the beginning of 1943, I lived at block 5, and then at block 24. Over that period, the suspect discharged the function of the Blockführer at, among others, the blocks I was staying at. He had a calm disposition and I did not even hear him abusing prisoners verbally. Once, in 1942, as I was on my way back from the Arbeitskommando [work detail], I noticed suspect Müller, who was returning with a rifle from the so-called Kiesgrube (a gravel pit). Since an execution took place at that time, I suspect that Müller actively participated in it. I did not witness the execution, this is merely my suspicion.
Beyond that, I cannot say anything negative about Müller. As the Arbeitsdienstführer, he treated prisoners humanely.
In 1944, I came across suspect Herbert Ludwig, who at that time was a Blockführer. I already knew his name then. Personally, I did not see him torture or beat prisoners, nor did I hear him abuse them verbally.
I had no direct contact with suspect Ludwig and I heard nothing negative about him.
