There can be no doubt that these volunteers, estimated by Neff to number about 10, are identical with the 10 “official experimental subjects” or “exhibition patients” mentioned already by the witness Vieweg, and it is noteworthy that Dr. Ruff, too, in his testimony always spoke of 10 or 12, or at the most 15 persons from the very beginning (of course he did not count them himself), who were regularly called in for the high-altitude experiments, and whom he saw himself when he was once present to observe and check the experiments in Dachau. This number Dr. Ruff had mentioned at a time when Neff’s and Vieweg’s testimony was not yet available. He therefore could not have anticipated that these witnesses would confirm his figures as correct. To be sure, the witness Neff testified in another place (_German Tr. p. 666_) that the first 10 experimental subjects were not volunteers. But this statement is obviously in direct contradiction to his other testimony which, in the last analysis implied—and could not be interpreted otherwise—that the so-called “10 official experimental subjects” were those prisoners who had voluntarily offered themselves, who were given all possible privileges in return, who were promised rewards for their service by Rascher as well as by Himmler, and who were repeatedly reassured that nothing would happen to them during the experiments. This whole presentation would be incomprehensible if one were to assume that these 10 persons were involuntary subjects as well, that they were simply ordered to take part in the experiments, forced to participate, for them all this would not have been necessary at all, since at that time nobody in a concentration camp would have thought of troubling himself about these people, if they had been forced against their will to take part in the experiments. In a concentration camp, according to the opinion of Himmler and his men, 1,000 people were of no consequence. Therefore, if efforts were made to obtain these inmates for the experiments, and to get them willingly, if even a Himmler found kind words to say to them and promised them rewards, then as we know today, this can only be explained by the assumption that even in concentration camps, for some reason, it was desirable to obtain voluntary subjects for the experiments and to induce them to go through the experiments voluntarily. This assumption is not refuted by the contrary assertion of Neff (_German Tr. p. 666_). For 1½ days, during his examination on 17 and 18 December 1947, Neff did not know that these first 10 experimental subjects had not been volunteers. For 1½ days he did not dare to make such an assertion here in the witness box, and only during the cross-examination did he finally go so far as to make this assertion, thereby completely overthrowing his previous statements.
