“The experiments which are to be performed on prisoners are to be carried out in four rooms of an already existing medical barrack. Only slight changes in the construction of the building are required, in particular the installation of the hood which can be produced with very little material. In accordance with attached plan of the construction management at Natzweiler, I request that necessary orders be issued to same to carry out the reconstruction. All the expenses arising out of our activity at Natzweiler will be covered by this office * * *.” (NO-978, Pros. Ex. 480.)
In a memorandum on 3 November 1942 to the defendant Rudolf Brandt, Sievers complained about certain difficulties which had arisen in Natzweiler because of the lack of cooperation from the camp officials. Sievers was particularly outraged by the fact that the camp officials were asking that the experimental prisoners be paid for. He said that:
“When I think of our military research work conducted at the concentration camp Dachau, I must praise and call special attention to the generous and understanding way in which our work was furthered there and to the cooperation we were given. Payment of [for] prisoners was never discussed. It seems as if at Natzweiler they are trying to make as much money as possible out of this matter. We are not conducting these experiments, as a matter of fact, for the sake of some fixed scientific idea, but to be of practical help to the armed forces and beyond that to the German people in a possible emergency.” (NO-098, Pros. Ex. 263.)
Brandt was requested to give his help in a comradely fashion in setting up the necessary conditions at Natzweiler. The defendant Rudolf Brandt replied to this memorandum on 3 December 1942, and told Sievers that he had had occasion to speak to Pohl concerning these difficulties, and that he had reported that they would be remedied. (NO-092, Pros. Ex 180.)
The witness Holl gave in his testimony an accurate and detailed description of the manner in which the Lost gas experiments were carried out. The execution of the experiments was supervised by Hirt in the experimental station Ahnenerbe in the Natzweiler concentration camp. In the middle of October 1942 the preparation for these experiments was finished and the actual experimentation began sometime in October or November, after the experimental subjects were given the same food as the SS guards for approximately 14 days. The first series of experiments was carried out by Hirt on 30 experimental subjects with a liquid gas substance. (Tr. p. 1051.) In spite of the fact that Hirt, before selecting these experimental subjects, had promised them that he would intervene with Himmler in order that they should be released as a reward if they would volunteer for the experiments, none of the experimental subjects of all the experiments carried out by Hirt volunteered. Political prisoners, Russians, Poles, Czechs, and also some German nationals were among the experimental subjects used. (Tr. p. 1052.)
The first series of experiments was carried out by Hirt and an officer of the Luftwaffe in the following manner: One drop of the liquid was applied to the lower arm of the experimental subject. Approximately 10 hours later burns began to appear and spread over the whole body in every place where drops of the fluid contacted the skin. Some of the experimental subjects became partially blind. The victims of these experiments suffered terrible pain. Photographic pictures of the burns were taken daily. After the fifth or sixth day of the experiment, the first fatality occurred. The corpse of the victim was dissected and the autopsy showed that the greater parts of the lungs and other organs had been destroyed. On the following day, that is, on the seventh day of the experiment, another seven of the experimental subjects died. The remaining 22 were sent to another concentration camp after approximately 2 months when they had recovered sufficiently and became fit for transport. (Tr. pp. 1052-3.) Other experiments on concentration camp inmates of the Natzweiler concentration camp were carried out in the gas chamber approximately 500 meters distant from the camp. The experimental subjects had to enter this gas chamber two by two. They had to smash small ampules which contained the liquid. This liquid evaporated and the experimental subject then had to inhale the resulting vapor. Usually the experimental subjects became unconscious and were returned to the Ahnenerbe station for further observation of the results of the experiments. (Tr. pp. 1053-4.) These results were approximately the same as those observed in the first series. The breathing organs of the experimental subjects were likewise destroyed. Their lungs had been eaten away by the gas. About 150 concentration camp inmates were experimented upon in this manner. (Tr. pp. 1034-5.) Approximately the same percentage as in the first series died as a result of this type of experimentation. (Tr. p. 1056.)
Other Lost gas experiments were carried out by means of injection. These experiments were carried out in a special room adjoining the crematorium. The victims of these experiments died without exception. (Tr. p. 1056.) Another type of experiment was carried out on the experimental subjects, who had to take the liquid orally. As Holl was transferred before Christmas 1943 to an outside camp, he was not able to give information on the results of this type of experiment. (Tr. p. 1056.) He, however, returned once a month to the Natzweiler concentration camp and was therefore able to observe that the Lost gas experiments continued until autumn 1944, when the Natzweiler concentration camp was liberated by the Allies. (Tr. pp. 1057-8.)
From Holl’s testimony it is proved that approximately 220 inmates of Russian, Polish, Czech, and German nationalities were experimented upon with gas by Hirt and his collaborators. About 50 of them died. None of the experimental subjects volunteered. (Tr. pp. 1052, 1057.)
On 7 April 1943, when the Lost experiments were well under way (supra), Himmler ordered an intensification of Lost research. At about this time the progress of Hirt’s Lost research was threatened by the transfer of Hirt’s assistant, Wimmer, a medical officer of the Luftwaffe. Since personnel matters fell within the scope of Sievers’ duties, he wrote to Rudolf Brandt protesting the proposed transfer of Wimmer and stating that if Wimmer left the Institute for Military Scientific Research, the Lost experiments would have to end. Sievers then outlined the proper procedure for securing the future services of Wimmer at the Ahnenerbe Institute. (NO-193, Pros. Ex. 264.)
Again, on 3 November 1943, Sievers, in order to further the Lost experiments and assure their continuation, made a certificate which enabled two of Hirt’s research assistants to obtain increased food rations. Sievers stated that the research activities in which these persons were engaged with Department H (Hirt), Strasbourg, of the Institute for Military Scientific Research of the Ahnenerbe involved health-damaging poisons which had caused injuries to their health.
