When answering the question whether the experiments could inflict torture and death on the experimental subjects, one has to distinguish between the experiments which according to the detailed instructions of Dr. Ruff were carried out by Dr. Rascher and Dr. Romberg in the Dachau concentration camp, and the experiments which Rascher carried out either with the knowledge and permission of Himmler, or without his permission on his own responsibility. With regard to the first experiments it has to be said that they caused the experimental subjects some discomfort through high-altitude sickness, but that on no account did they mean torture and death for the experimental subjects. (Evidence of Dr. Ruff in direct examination.) On the other hand the experiments which Rascher conducted on his responsibility have, according to Prosecution Document 1971-A-PS (_Pros. Ex. 49_), apparently to be judged in a different manner. Sievers came in contact with the low-pressure experiments only; in the second half of March 1942. By letter of 21 March 1942 Rudolf Brandt replied to an inquiry of the Reich business manager of the Ahnenerbe of 9 March 1942 concerning Rascher, and informed him that low-pressure experiments were carried out in the Dachau camp: “The Reich Leader SS gave his permission on condition that Dr. Rascher would participate.” (_1581-A-PS, Pros. Ex. 48._) The cause of Sievers’ letter of 9 March 1942 was the statement of Dr. Rascher to the curator Wuest, according to which certain research work which he carried out for the Luftwaffe in Dachau, and of which he could give no details, was to be supported by the administration of the “Ahnenerbe”. (_German Tr. p. 5671._) Following this, Sievers went to Dachau in late March or on 1 April 1942. (_German Tr. p. 5672._) Thus this date was the earliest on which Sievers could possibly have gained knowledge about the carrying out of high-altitude experiments in Dachau. It is important that at this time the experiments had already been under way for over a month. The cunning Rascher took the first visit of Sievers as an opportunity to invite Sievers to have a look at the experiments directed by him, in spite of the fact that Sievers had nothing at all to do with the carrying out of the experiments. Sievers watched two experiments. He took the opportunity to speak to the two persons who were subjected to the experiments on that day. Both told Sievers that they had volunteered for the experiment. A few minutes after the experiment both experimental subjects did not show any after-effects and finished the experiment without suffering any bodily or physical damage. (_German Tr. p. 5741._)
