As for the list of crew members of the Auschwitz garrison that has been read out to me, I can only testify regarding war criminals: a) Sturmbahnführer Karl Heinz Joachim Theuber vel Teuber; b) Hauptsturmführer Hans Aumeier; c) Hauptsturmführer, who is listed as Untersturmführer Max Grabner; d) Hauptscharführer Wilhelm Gerhard Gehrin; e), Obersturmbahnführer Artur Liebehenschl. I encountered the above during my stay in Auschwitz from January 1940 to 1944. Then I was transferred to the camp in Świętochłowice, where I stayed in the years 1944–45 and where I met the accused Gehring. Regarding the above I can state as follows:
1. Karl Teuber I know personally. He was my boss at the dental clinic in Auschwitz in 1942–43. As a boss, he behaved well with his prisoner subordinates. He was demanding, but he never hurt anyone. As far as possible, he was interested in the fate of the prisoners and how he could help them.
2. Hans Aumeier I know as a Lagerführer [head of the camp] in Auschwitz. He was a sadist
and terrorized the prisoners. He tormented the prisoners awfully, whom, regardless of their sex, he beat in horrific ways at every occasion. He participated in all the gassings and executions. He acted eagerly and with a smile on his face. During executions, he killed the prisoners with his revolver. His favorite “game” was to shut the prisoners in the bunker in the block 11, where they would suffocate from the lack of air. During the roll calls in the winter, he kept the prisoners for three to four hours. Because of this, many prisoners lost their lives.
3. Max Grabner I know personally as head of the political department at the Auschwitz camp. He personally took part in all the executions. During prisoner interrogations he used bestial methods, told the SS men to beat the prisoners inhumanely to the point where the prisoner would be so wrecked that he couldn’t stand on his feet and it often occurred that after such an interrogation he would be carried out dead.
4. Wilhelm Gehring I know personally as a Lagerführer in the Świętochłowice camp in 1944–45.
He behaved violently towards the prisoners for any reason whatsoever or even no reason. He beat and kicked the prisoners. His favorite form of “entertainment” was to put prisoners between electric wires, where the victim had to stay for two days and two nights without food. He took part in executions, beating and torturing the prisoners immediately before putting them on the gallows. He fulfilled his duties so lovingly that he was among the last to evacuate the camp to Mauthausen, and on the way he saw to it that many of the prisoners lost their lives.
5. Artur Lebehentschel I know personally as the commandant of the Auschwitz camp. After taking up this post, he issued a ban on beating and punishing prisoners without his knowledge. While he was the commandant of the camp, there were no executions or any gassing. He forbade the hitherto custom of prisoners having to doff their caps to the SS men. He sent all the prisoners who were informers of the political department to other camps, which cleared the atmosphere. During his time, various conditions in the camp changed and there was far less tension.
This is my testimony which I signed after it was read out.
