Sievers had not the power or the opportunity of preventing Rascher’s criminal experiments or of bringing them to a standstill. It is true that at the Easter conference in 1942 he tried to move Himmler to discontinue all experiments in the concentration camps, or at least to bring about the suppression of the research of Rascher and Professor Dr. Hirt, which were not in harmony with the character of the Ahnenerbe. Both his suggestions were refuted by Himmler’s declaration that “all that” was no concern of Sievers and that he (Himmler) bore the sole responsibility. (German Tr. p. 5714.)
In spite of Himmler’s declaration, Sievers endeavored to halt further low-pressure experiments, when the low-pressure chamber had been removed from Dachau at the beginning of June 1942.
Already on 27 November 1942, the chief of the personal staff of the Reich Leader SS, SS General Wolff, had applied to Field Marshal Milch in order to make possible Rascher’s further experiments in Dachau. In the closing sentence of this letter the loan of the low-pressure chamber is once again requested. (NO-269, Pros. Ex. 78 (Pros. Ex. 118 in the Milch Case).)
That General Wolff by Himmler’s orders laid great stress on making further experiments possible is seen from the fact that a copy of the letter went also to SS Oberfuehrer Dr. Wuest, who was office chief of the Ahnenerbe. Thereby the special importance of the affair was to be shown also to the Ahnenerbe, on which the obligation rested to procure the requisite apparatus in accordance with figure three of Himmler’s order of 7 July 1942 (NO-422, Pros. Ex. 33) and repeated later under figure five of Himmler’s order of 13 December 1942 (1612-PS, Pros. Ex. 79).
When the Luftwaffe did not make the low-pressure chamber available again, Sievers was commissioned to buy a special portable low-pressure chamber for the SS. (German Tr. p. 5800.) And then Sievers did something unheard of and rang up Dr. Romberg of the German Experimental Station for Aviation. Romberg was very much surprised at this telephone call. (German Tr. pp. 6839-40.)
Through his communication that he had been commissioned by Himmler to procure a low-pressure chamber for Rascher, who at that time was still a member of the Luftwaffe, he aroused the attention of the Luftwaffe. For Dr. Romberg communicated this news to his superior Dr. Ruff, who, on his side, informed Dr. Becker-Freyseng of the Medical Inspectorate of the Luftwaffe. (German Tr. pp. 6607-08, 7878; Becker-Freyseng 24, Becker-Freyseng Ex. 11.) This was what Sievers counted upon. The consent of the Luftwaffe would have been necessary for the purpose of sanctioning the requisite priority grade for a low-pressure chamber. The Luftwaffe denied this necessity and thus the low-pressure chamber under consideration for Rascher was not procured.
When Himmler in the year 1943—probably at Rascher’s urging—ordered Sievers again to procure a low-pressure chamber, Sievers was able once more to prevent one from being procured. This time he pointed out that the research management of the Luftwaffe did not consider it necessary to continue with altitude experiments. Sievers advanced this statement at random, profiting by the fact that Rascher, though probably known to the Medical Inspectorate of the Luftwaffe, was not known to the research management of the Luftwaffe. (German Tr. p. 5801.)
Summary
Criminal action on the part of Sievers cannot be proved in connection with the low-pressure experiments. The carrying out of the experiments was neither ordered nor arranged for by him. He did not come into contact with the experiments until they had been in progress for over a month. What Sievers saw, heard, and read about the experiments could not in any way give him the knowledge that inadmissible experiments were being made. Sievers had no knowledge of Rascher’s criminal experiments while the experiments were in progress, because Rascher kept these experiments completely secret. Sievers’ activity was of a completely subordinate nature. Apart from that, however, Sievers helped to prevent Rascher (whom Sievers could not bear, for he was a pompous fellow and a protégé of Himmler) from being put again in a position to carry on further low-pressure experiments.
There is no criminal guilt then on the part of Sievers, as far as Sievers’ contact with the low-pressure experiments is concerned.
