In July Hitler told Lammers, Bormann, and Dr Leonardo Conti (recently appointed Reich Health Leader and State Secretary for Health in the Reich Ministry of the Interior) that he favoured mercy-killing for seriously ill mental patients. Better use of hospitals, doctors, and nursing staff could be made in war, he stated. Conti was commissioned to investigate the feasibility of such a programme.164 By then, war was looming. Hitler’s own comments showed that he continued to see a ‘euthanasia programme’ in the context of war. By that time, too, Hitler had probably received the evaluation commissioned around the start of the year by Brack from Dr Joseph Mayer, Professor of Moral Theology at the University of Paderborn. Hitler had been uneasy about likely reaction of the Churches in the event of the introduction of a ‘euthanasia programme’. He imagined both the Catholic and Protestant Churches would outrightly oppose it. Mayer, who in 1927 had published a tract in favour of the legal sterilization of the mentally sick, was now asked to assess the attitude of the Catholic Church. He sided with the right of the state to take the lives of the mentally ill. Though this was against orthodox Catholic teaching, Mayer left the impression that unequivocal opposition from the Churches was not to be expected. This was the conclusion which Hitler apparently drew, following further discreet inquiry.165 The biggest internal obstacle to such a programme appeared to be surmountable. The programme could go ahead.
The organization, set up to deal with the ‘euthanasia’ of children, was to hand. Brack had heard indirectly of Hitler’s instructions to Conti at the July meeting.166 Spotting his chance, but needing to act without delay, if control were not to be lost to Conti and the Reich Ministry of the Interior, he had Hefelmann draw up a short statistical memorandum on the asylums and took it to Bouhler. The head of the Führer Chancellery had little difficulty in persuading Hitler to extend the authorization he had earlier granted to himself and Brandt to deal with the children’s ‘euthanasia’. It was in August 1939 that Hitler told Bouhler that he wanted the strictest secrecy maintained, and ‘a completely unbureaucratic solution of this problem’. The Reich Ministry of the Interior should be kept out of it as far as possible.167
Shortly after this, a sizeable number of doctors were summoned to a meeting in the Reich Chancellery to seek their views on such a programme. They were overwhelmingly in favour and ready to cooperate. They suggested that around 60,000 patients might be ‘eligible’.168 The number involved meant there was a serious problem about maintaining secrecy. Once more, camouflaged organizations were needed. Three were set up to distribute questionnaires to the asylums (the Reich Association of Asylums), handle personnel and finance matters (Community Foundation for the Care of Asylums), and organize transport (Community Patients’ Transport). They were based, under Brack’s direction, in an unpretentious villa in Berlin-Charlottenburg, Tiergartenstraße 4, from which the entire ‘euthanasia action’ drew its code-name ‘T4’. Apart from Bouhler, Brandt, and Brack the organization comprised 114 persons.169
Plainly, the construction of such an organization and the implementation of its gruesome task needed more than simply the verbal authorization that had sufficed for the children’s ‘euthanasia’ up to then. This is what prompted Hitler’s almost casual written authorization some weeks later, backdated (as we noted) to I September. This formless empowering, and the way the Führer Chancellery had been able, without the ministries of state even being informed, to expropriate control over a programme calculated to bring the deaths of tens of thousands in an action lacking any basis in law, is the clearest indication of how far internal structures of government had been deformed and superseded by executive agencies devoted to implementing what they saw as the will of the Führer. The cloak-and-dagger secrecy — some leading figures, including Brack, even worked with false names — highlighted the illegality of what was taking place.170 The regime had taken the step into outright criminality.
The medical staff of the asylums selected their own patients for inclusion in the ‘euthanasia action’. They, too, were ‘working towards the Führer’, whether or not this was their overt motivation. Patients included had their names marked with a red cross. Those to be spared had a blue ‘minus’ sign against their names.171 The killing, mostly by carbon monoxide gas administered by doctors under no compulsion to participate, was carried out in selected asylums, the most notorious of which were Grafeneck, Hadamar, Bernburg, Brandenburg, Hartheim, and Sonnenstein.172
