The witness Dr. Lutz for example, who was introduced by the office of the public prosecutor and therefore recognized by it as a credible witness, confirmed here on oath, “it was a tacit assumption that the criminals would volunteer”; and he added that he could almost say that, in a way, a favor was being conferred upon the criminals, because “they were given a chance of pardon by participating in the experiments,” and it is significant that this witness deposed further: “subsequently, we were very much surprised when, probably during the later stages of the experiments, as far as I recall now, no further mention was made of it,” namely, of the fact that only volunteers were to be used for the altitude experiments (German Tr. p. 320).
These depositions by the witness Dr. Lutz conform in every respect with the general impression received from all the pertinent descriptions. At first, only the altitude experiments approved by Dr. Ruff regarding the problem of “rescue from high altitudes” were carried out. These experiments were not dangerous as proved by their successful outcome; the inmates volunteered for them. Gradually, however, Rascher misused more and more the presence of the chamber in order to conduct his arbitrary experiments on Himmler’s orders for entirely different problems, namely, to conduct his notorious “difficult experiments” which had numerous fatal results. These were Rascher’s more cruel, painful experiments; naturally, no more volunteers reported for these because word was passed quickly through the camp that the experiments which Rascher himself conducted were dangerous, while the mere presence and cooperation of Dr. Romberg gave assurance to the inmates that his experiments were conscientiously conducted and were not dangerous.
Other witnesses also, not named by Dr. Ruff, have confirmed that the experimental subjects for the Ruff-Romberg high-altitude experiments were voluntary, namely, the witness Dr. Hielscher (German Tr. pp. 6025-26, 6041, 6062). Testimony on similar lines is given by the codefendant Sievers (German Tr. pp. 5471, 5881); and Dr. Hippke (German Tr. p. 793) “Prisoners who might volunteer”; (German Tr. p. 795) “these persons had to volunteer for the experiments.” Also the witness Karl Wolff, (Ruff 21, Ruff Ex. 20) “volunteer concentration camp inmates who were to be given compensatory privileges * * * the inmates, about 10 in number, appeared quite relaxed and, in their turn, willingly entered the low-pressure chamber which had been driven up * * * the inmates reported to Himmler, in my presence, that in this manner they could at least voluntarily * * * give a proof of their genuine good will * * * I never learned through Himmler, nor, as far as I remember, by any other means that later low-pressure chamber experiments * * * took place on a nonvoluntary basis * * * I only knew about voluntarily low-pressure chamber experiments and these were made, without doubt, on a voluntary basis.” Finally, the witness Herbert Wilschewske (Ruff 11, Ruff Ex. 9).
While the previous witness Wolff was only present for 1 day during the experiments, the witness Wilschewske, during the 2 years he spent in the concentration camp, spoke repeatedly to inmates who “had volunteered for the medical experiments”, and who, by reason of his repeated conversations with the prisoners, could give the following as reason for the willingness to volunteer for experiments “they could earn thereby their own liberty and rehabilitation as well as privileges for their family.” The witness Wilschewske is certainly an absolutely reliable witness with regard to his statements. He is a Polish Communist, served 2 years in Dachau concentration camp for this, and was proved to be only a political prisoner.
If one considers all these statements by witnesses, which certify that the experimental subjects in the Dachau high-altitude experiments of Drs. Ruff and Romberg were volunteers, it cannot be doubted that the concordant statements by Dr. Ruff, Dr. Romberg, and Dr. Weltz were absolutely true. They are defendants, it is true; but from all sides testimony is given of their irreproachable professional integrity. Although they are now sitting in the dock, their precise and clear statements deserve far more belief than the changing and contradictory statements of a habitual criminal who has committed downright perjury in this Court, or of a murderer who is actually more deserving of a place in this dock than these defendants are.
The correctness of this conception is confirmed again on the one hand by the fact—already mentioned in another connection—that Dr. Romberg, as has been proved repeatedly, actively intervened and prevented the use of experimental subjects for experiments by Rascher when he could see that nonvoluntary experimental subjects were to be used, and on the other hand, it was known that in the high-altitude experiments which Dr. Ruff had carried out with Dr. Romberg only voluntary experimental subjects could be used, and only with voluntary experimental subjects could the experiments succeed. The whole idea of this type of high-altitude experiment (the Ruff-Romberg method) was based on the theory that the experimental subject, immediately on recovering from the state of unconsciousness—the “high-altitude malady”—reaches up with his arm and pulls down the handle of the parachute, which in practice reduces the speed of the fall, insuring the flier of a smooth landing on the ground. All this necessitated active cooperation on the part of the experimental subject; one was absolutely dependent on his cooperation, otherwise each of these experiments would have been useless right from the start. Naturally, Dr. Ruff knew this, as did Dr. Romberg, and therefore for them the first and most important condition for each experiment of this type was that the experimental subject should be voluntary (see Ruff’s statement in German Tr. pp. 6638-40). There are therefore also important inherent reasons why the statements by Ruff and Romberg are correct.
Actually the high-altitude experiments carried out in Dachau were successful. They were of considerable help in clarifying the problem of “rescue from great heights”, and this was only possible when the experimental subjects themselves cooperated when they took part in the experiments voluntarily and took an interest in them. This was, by the way, also the reason why this type of high-altitude experiment could not be made with animals as experimental subjects, a fact which, for example, Ruff and Romberg pointed out in their summary report of 28 July 1942. (NO-402, Pros. Ex. 66.)
I come, therefore, to the following conclusion: There can be no doubt that the experimental subjects for the Dachau high-altitude experiments were volunteers, at least as far as the experiments authorized by Ruff are concerned. Whether volunteers reported for the special experiments continued by Dr. Rascher or whether the prisoners were forced into the experiments by Dr. Rascher does not need to be examined, because Ruff and Romberg did not participate in those experiments in any way. But even if any doubt as to their being volunteers were possible, it cannot be denied that Ruff and Romberg were firmly convinced that all their experimental subjects actually were volunteers. This was stipulated from the very beginning, and in all the discussions of Dr. Ruff with Hippke, Weltz, and the representative of the SS, Ruff was consequently convinced that only volunteers were actually concerned.
Dr. Ruff’s conviction was strengthened through personal conversation with various prisoners on that day on which he himself went to Dachau to control the execution of the experiments and to ascertain that everything was carried out in a completely orderly manner. And finally in this connection it cannot be overlooked that Dr. Ruff, as he has stated under oath and as is confirmed by numerous affidavits, had never at any other time in his life worked with nonvoluntary experimental subjects. Just because he considered it indispensable for the success of the experiments that the experimental subjects were volunteers, that they themselves cooperate, Dr. Ruff never thought that the Dachau prisoners were not fully and completely in agreement with the experiments.
