In June 1945, during investigations by
US Forces into the former gassing facility at Hartheim, the
American investigating officer Charles Dameron broke open a steel safe in which the
Hartheim statistics were found. This was a 39-page brochure produced for the internal purposes of the Nazi "euthanasia" programme (
Aktion T4), and contained monthly statistics of the gassing of mentally and physically handicapped patients (called "disinfection" in the document) carried out in the six killing centres on the territory of the Reich. In 1968 and 1970, an ex-employee of the establishment revealed, as a witness, that he had to compile the material at the end of 1942. The Hartheim statistics included a page on which it was calculated that "disinfecting 70,273 people with a life expectation of 10 years" had saved food in the value of 141,775,573.80
Reichsmarks. These statistics only cover the first extermination phase of the Nazi's euthanasia programme,
Action T4, which was brought to an end by
Hitler's order dated 24 August 1941 after protests by the Roman Catholic Church. In all it is estimated that a total of 30,000 people were murdered at Hartheim. Among those killed were sick and disabled persons as well as prisoners from concentration camps. The killings were carried out by
carbon monoxide poisoning.
14f13 "Special Treatment" Three days after the formal end of Action T4, a lorry arrived at Hartheim with 70 Jewish inmates from
Mauthausen concentration camp, who were then executed. Some of the prisoners at Mauthausen who were no longer capable of working, especially in the quarries, and politically undesirable prisoners were brought to Hartheim to be executed. In the papers these transfers were disguised with terms like "recreation leave". The entries under "sickness" included "German-haters", "communist" or "
Polish fanatic". From 1944 on, the prisoners were no longer selected by T4 doctors; the objective was simply to gain space in the Mauthausen camp quickly. == Execution doctors ==
