I was brought to the Auschwitz camp as a prisoner in March 1942. At the end of that year, I was assigned to an SS division’s storehouse, where I worked as a clerk. The deputy of the storehouse director was Artur Breitwieser. At first, he had the rank of SS-Rottenführer, but in 1944 he was promoted to SS-Unterscharführer. I heard that he was a Polish citizen from Łódź, and that he had a Master’s degree in Law. He spoke Polish very well and he would speak German only if he was not able to communicate with a prisoner in Polish. I never saw him beat the prisoners or abuse them physically in any other way. However, he zealously performed his duties and reported any offence committed by prisoners to the storehouse director, who would punish them personally.
I did not see Breitwieser do anything good for the prisoners. At the beginning of 1944, as a result of his wrongdoings, Breitwieser and the whole storehouse personnel were transferred to a different location, and I lost contact with him.
