A. Since this letter prevented me from doing anything, I calmly asked him what idea he had of these experiments, what he wanted to do, what he wanted to achieve. He said that Dr. Fahrenkamp would help him and that he would have electrocardiograms for heart failure from the most various reasons and would compare them with electrocardiograms in the case of death at high altitudes with the change in severe altitude sickness and with later recovery. In addition, in the hospital in Munich he had taken electrocardiograms in cases of heart failure. In Dachau, he said, he had also registered electrocardiograms when there were executions by shooting. If he really had evaluated all this material together with a heart specialist, then it would, of course, have been quite valuable. * * * * * Q. Now, did you do anything, and what did you do in order to stop Rascher’s experiments and did you incur any danger and, if so, what? A. What I did against Himmler’s orders and against my signed promise to keep secrecy, the fact that I reported the incidents to my boss who passed the information on—all this was dangerous. One probably understands enough about conditions under Himmler to realize that. The witness Neff has described my attitude to Rascher’s experiments. He confirmed that I intervened in one case when he was present. Perhaps he knows nothing about my other objections. In general, the discussions between Rascher and myself did not take place in the presence of the prisoners. The low-pressure chamber was removed from Dachau earlier than intended at our instigation. Against Rascher’s and Himmler’s wishes, it was never returned to Dachau. The extent of the accusations made by the SS in this direction is shown by the document. These efforts begin with Wolff’s telegram to Milch on 12 May, which is answered in the negative in Milch’s letter of 20 May. (_343-A-PS, Pros. Ex. 62._) In answer to further efforts from Himmler, Milch ordered that the chamber was to remain 2 months longer in Dachau. (_NO-261, Pros. Ex. 63._) At this time, we had already removed the chamber. On 5 June, Rascher again writes to Himmler about the low-pressure chamber. Document NO-284, Prosecution Exhibit 64, is the answer to this letter of 5 June. The letter itself is, unfortunately, not available. This letter, no doubt, says that the chamber was removed from Dachau in May, while the prosecution alleges that the experiments continued until August. Then there is a certain pause in Rascher’s and Himmler’s efforts, because Rascher is busy with the cold experiments. When the film is shown in Berlin in the Air Ministry, Rascher does not forget to tell Milch again of his wishes in regard to the low-pressure chamber. But hardly has the first phase of the cold experiments—the series with Holzloehner—been finished, when he writes to Himmler again on 9 October. (_1610-PS, Pros. Ex. 73._) He asks Himmler to get him the low-pressure chamber so that he
