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
