Georg Bachmayer (August 12, 1913 – May 8, 1945) was an SS-Hauptsturmführer (captain) and member of the SS-Totenkopfverbände who served as the Schutzhaftlagerführer, with responsibility for prisoners while they were inside the Mauthausen concentration camp, he also oversaw granite production in the quarry.
In this position he also inspected the satellite camps and supervised the construction of the Ebensee camp. He was considered a brutal sadist : "Bachmayer was clearly a sadist. His speciality was to set two mastiff-like bloodhounds (one in 1944 "Lord") on inmates, which would literally tear them to death. This was known in camp jargon as ‘dying from the dog’s kiss’. The real cause of death from a medical point of view was usually general sepsis, if the inmate didn’t die immediately of heart failure. Of the thousands of inmates that Bachmayer himself killed or tortured, just two cases are mentioned here. One day the evening roll call in block 20 didn’t tally and one inmate was missing. In block 20 the unfortunate victims of Action K were housed under special security measures [...] where they were left to die of hunger.
When the missing inmate was noticed, all the other inmates in the entire camp were first required to fall in and remain standing in the roll call area. At the same time a search was initiated and the missing inmate was ultimately found in one of the normal inmate blocks where he had hidden in the hope of avoiding starvation. When Bachmayer received the report that the inmate had been found, he was standing by chance next to the undersigned. He began to tremble with gleeful excitement and said half to himself ‘I’ll batter this one to death myself’, which he then proceeded to do."
