The further possibility of perhaps using German civilians for the experiments was completely out of question because at this time it was not possible to find young men in the age groups necessary in this case among the German civilian population, because all of them had either been conscripted for military service or for labor service. Professor Schroeder, therefore, had no choice but to follow the suggestion of considering Dachau concentration camp for his experimental station.
Professor Schroeder was not informed at all about conditions in a concentration camp. He thought the circumstances in such a camp were no different from those prevailing in a military camp, and only the names Dachau and Oranienburg were known to him as concentration camps. In this connection, it may be pointed out that the SS surrounded events in the concentration camps with an almost impenetrable veil of secrecy. Schroeder never listened to foreign radio stations. In the circles of his medical officers such events were never discussed. I may point out here that an express opponent of National Socialism, no less than the former Prussian Minister of the Interior, Severing, testified as a witness in the IMT trial that he had had no knowledge of the events in the concentration camps, and he had different sources of information at his disposal from Professor Schroeder. If Professor Schroeder had had any idea of what happened in concentration camps while he was away from Germany, then in view of his ideology as a faithful Christian, he would have refused such contact with concentration camps arising out of ordering these experiments. The decisive point in Schroeder’s favor is that the experiments were not to be carried out under the supervision and command of the SS camp leadership but completely separate, under the special leadership of a Luftwaffe medical officer and recognized specialist. As a further consideration, Professor Schroeder had to take into account that a useful result could be achieved in these experiments only if they could be carried out without interruption or hindrance. Because of the then prevalent almost daily air raids over the whole of Germany, no guarantee for an uninterrupted execution of these experiments could be given in any spot in Germany. However, it was known that air raids on concentration camps did not take place. Moreover, the charge cannot be brought against Professor Schroeder that he chose a concentration camp because he then had available defenseless tools who perforce had to subject themselves to the experiments. The very opposite is true. It was clear to Professor Schroeder that if he wanted to be successful he could carry out these experiments only with voluntary experimental subjects, for the director of the experiments was dependent on the willing cooperation of the experimental subjects, since in no other way could usable clinical data be achieved. Every involuntary experimental subject would have had the power to drop out of the experiment prematurely by feigning indisposition or pain, and, in this way, would have caused the director of the experiment to terminate it prematurely.
For the further evaluation of Professor Schroeder’s conduct, his conversation with the Reich Physician SS Grawitz must be considered especially. Professor Schroeder expressed the opinion to Grawitz that he could only work with healthy and voluntary experimental persons, whose age corresponded to that of the pilots under his command, and he made the further condition that the experimental persons should have the same physiological and racial requisites as the members of the German Wehrmacht in question. On direct examination, Professor Schroeder testified under oath that in this connection he talked to Grawitz about dishonorably discharged former members of the German Wehrmacht who, he knew, had been transferred to concentration camps because of the seriousness of their offenses.
Professor Schroeder could not assume, nor was any report on the part of Grawitz or the SS leadership made to him, that the SS leadership did not accept this suggestion and that instead of former members of the German Wehrmacht, gypsies had been decided upon for experimental purposes. Professor Schroeder, from his point of view, could rely on Grawitz to make arrangements according to his suggestions; he had no reason to expect that the SS would decide upon experimental subjects, against his well-founded wish, who, racially and physiologically did not have the prerequisites demanded by Professor Schroeder.
Because of the extremely heavy official duties caused for Professor Schroeder in his capacity as chief medical officer by the imminent collapse of German military resistance, this affair was only a small segment of his official duties and it must be admitted that he could not concern himself further with this affair.
A further consideration which Professor Schroeder had to bear in mind was whether such experiments were dangerous and possibly damaging to the health of the experimental subjects. Professor Schroeder had thoroughly studied this question and contemplated all possible aspects of the problem. Professor Schroeder also knew that sea-water is used by doctors for drinking cures and that the criterion of harmfulness depends on the doses. If there was medical supervision then there would be no danger to health. Therefore, the prosecution’s charge that he failed to take the possible hazards sufficiently into account is not justified.
Nothing shows the high degree of responsibility which characterized Professor Schroeder more than the instructions which the medical inspector issued to the man carrying out the experiments.
Professor Schroeder was convinced that the experiments held no danger to the experimental subjects and he expressed this opinion to Reich Physician SS Grawitz. Such danger was excluded particularly if and when the quantity of sea-water to be taken was regulated in accordance with the best medical experiences, and when it was definitely ordered that the experiments should be stopped at a certain time; and, furthermore, if the selection of the man in charge of the experiments guaranteed, on the basis of professional and ethical standards, that the experiments would be carried out in a humane manner, taking into account all medical and clinical considerations.
Therefore, it is fully justified if Professor Schroeder claims that he, from his position as a physician and a leading medical officer, considered all possible situations and attempted to avert all possible sources of danger as far as humanly possible. His direction to the man in charge to discontinue the experiments as soon as the experimental subject refused to take in further water, and if dangerous injury to the body were recognizable, must be mentioned in Schroeder’s favor. The person carrying out the experiments was furnished with all necessary assistants and a number of special co-workers from medical circles as well as all machinery to carry out his work in an orderly fashion.
The contention that both the planning and preparation of the experiments by Schroeder can stand any examination, that that planning was with full moral responsibility and with a true feeling of duty and humanity was reaffirmed, too, before this Tribunal by Professor Dr. Vollhardt, as well as by the American expert, Professor Ivy. It is simply unthinkable that instructions to one conducting experiments could be more correct from a medical point of view than those which Professor Schroeder worked out.
