It is incredible that Dr. Ruff was not informed regarding the finding of bubbles in the blood vessels of the brain since such observations in human beings who have died following too rapid atmospheric decompression is a very, very unique event, though bubbles had been observed many times prior to 1942 in the blood vessels of laboratory animals. It is inconceivable that Dr. Ruff, or anyone else in the field of aviation medicine, had not heard of the bubble theory of the cause of joint pains, coughing, blindness, or paralysis, or the symptoms of the pressure drop sickness, which may occur on exposure to high altitude, since this theory was well known in literature and text books of aviation medicine available since 1938. How else would Rascher have had occasion to look for the bubbles? He either learned of the theory during a course in aviation medicine or was told about it by Ruff and Romberg, who knew much more than Rascher about aviation medicine.

It is fantastic that Ruff, Romberg, and Rascher did not have in mind the observations of bubbles in the blood vessels of the murdered prisoners, when, in the final joint report of 28 July 1942, they wrote:

“In spite of the relatively large number of experiments, the actual cause of the severe mental disturbances and bodily failures (paralysis, blindness, etc.) attendant upon post-hypoxemic twilight state remains something of a riddle. It appeared often as though the phenomena of pressure drop sickness had combined with the results of severe oxygen lack”. (NO-402, Pros. Ex. 66.)

It has been the theory for some time that the symptoms associated with decompression or pressure-drop sickness may be due to the formation of gas bubbles (air embolism) in the blood vessels of the brain or in the regions of the joints or in the blood vessels of the lungs. When the bubbles collect in the blood vessels of the brain, they are supposed to cause a physical or mental disturbance or paralysis. When the gas bubbles collect in the region of the joints, they are supposed to cause pain in the region of the joints. When the bubbles collect in the blood vessels in the lungs, they are supposed to cause the chokes or attacks of coughing. That has been a theory that has been held for some 15 or 20 years, and an expert in the field of aviation medicine could not have been unaware of it. (Tr. pp. 9098-9.) Since Rascher had observed bubbles as is described in his report of 11 May 1942, and since Ruff and Romberg had complete knowledge of the deaths, obviously these important findings of Rascher on air embolism did not escape the attention of Ruff and Romberg. It can only be concluded that these findings, which resulted from intentioned deaths, form the basis of the paragraph quoted above from the final report. Because of the nature of the subject matter, and a prior knowledge of the observations in the autopsies in the experiments, the ideas expressed in the paragraph quoted above cannot be separated from those in the Rascher report of 11 May. So testified the expert witness Dr. A. C. Ivy. (Tr. p. 9151.) All of this proves again that the testimony of Ruff and Romberg to the effect they had nothing to do with the so-called “Rascher experiments” is completely false. Even though deaths are not specifically mentioned in the joint report of 28 July, it is clear from Dr. Ivy’s testimony that the findings in the death cases form the basis for a part of that report.

Ruff and Romberg would have the Tribunal believe that the experiments were completed and the chamber removed from Dachau by 20 May 1942. Since Romberg knew of and reported on the deaths to Ruff in April, there clearly was no excuse whatever to leave the chamber in Dachau for even another day. But according to their own story, it stayed until 20 May and Romberg saw two more men killed. They attempted to gloss over their criminal participation in these later murders by saying that the chamber could not be moved without orders from the Luftwaffe Medical Inspector. Be that as it may, such a technical violation of moving the chamber without orders is hardly comparable to the crime of leaving the chamber for further experiments by a man whom they admit they knew to have been a murderer. Indeed, any decent superior who was not himself a party to the crime, as they actually were, would undoubtedly have court-martialed Ruff and Romberg for leaving the chamber there, not to speak of Rascher.

But it is not true that the chamber left Dachau on 20 May 1942 as they perjuriously stated. They seized upon this date from Milch’s letter to Wolff stating that the chamber was needed elsewhere. (343-A-PS, Pros. Ex. 62.) There clearly was an intention to transfer the chamber, but it was not in fact moved and this was undoubtedly due to the joint efforts of Ruff, Romberg, and Rascher. Romberg was anxious to continue his criminal work with Rascher in September 1942 as has been pointed out above. In any event, on 4 June 1942, Milch authorized retention of the chamber in Dachau for two more months. (NO-261, Pros. Ex. 63.) On 25 June this order was passed on to Rascher by Heckenstaller, adjutant to Wolff, reference being made to a letter of 5 June from Rascher. (NO-284, Pros. Ex. 64.) These documents prove beyond doubt that the chamber remained in Dachau until July 1942.

The testimony of Neff not only proves that the experiments continued until July 1942 but also that Romberg was presented with a remarkable opportunity to discontinue the experiments without any trouble whatever. Neff stated that Romberg told him in the latter part of May that the chamber was to be transferred (undoubtedly as a result of Milch’s letter of 20 May which was later countermanded) and, under the impression that Romberg might not be in favor of any continuation of the experiments, he sabotaged the chamber by breaking a glass barometer in order to make sure the chamber would be sent away. Instead of seizing this opportunity for stopping the experiments by removing the damaged chamber, Romberg rushed to Berlin, obtained spare parts, and in a matter of 2 weeks had the chamber functioning again for more murderous experiments. (Tr. pp. 623-4.) The chamber was used for another 3 weeks after it was repaired and five persons were killed on the last day of the experiments. (Tr. p. 624.) Although the defense attacked Neff on cross-examination concerning the sabotage of the chamber (Tr. p. 663), by the time Romberg took the stand they admitted the chamber was damaged but moved the whole incident to the month of May instead of June. (Tr. p. 6905.) This was obviously done on the theory that the Tribunal could be deceived into believing that very few experiments could have been conducted in May since they contend the chamber was moved on 20 May. But the documents and Neff’s testimony clearly established that the chamber was there until July. Moreover, it matters little whether the chamber was damaged in May or June. Romberg in no event took the opportunity to stop the experiments on the ground of unavailable spare parts, although this opportunity would not have been needed if he really wanted to discontinue them. He need have done nothing more complex than to have sent the chamber away or left himself.

Ruff’s and Romberg’s guilt is beyond doubt when we consider that they did not take the opportunity to withdraw after the first death of an experimental subject in April 1942. Romberg admitted his presence at the death of this first subject. (Tr. p. 6924.) He was studying the electrocardiogram at the time of the experiments (NO-476, Pros. Ex. 40), but he would have the Tribunal find that he was an innocent bystander who was privileged to do nothing. This was just another “SS experiment” according to Romberg. But Romberg admitted that he was working the electrocardiogram and was studying the point of light that follows the heart. When he saw that the critical point had been reached, he said he spoke to Rascher (Tr. p. 6927), but to no avail as Rascher continued the experiment until death resulted. This testimony of assumed impotence when a man was slowly killed before his eyes is an insult to one’s intelligence. Romberg was the senior scientist and was fully aware of the fact that the danger zone had been reached as he was thoroughly familiar with the equipment being used. He has outlined for the Tribunal the proximity of the electrocardiogram to the controls of the chamber (Tr. p. 6929), and it is inconceivable that Romberg could not have taken the necessary action to have spared this experimental subject’s life if he had so desired. The inescapable fact is that these deaths were part of the plan and Romberg not only had no desire to interfere but was very much interested in the cause of death through air embolism.

Assuming that Romberg was opposed to this fatal experiment, it is impossible to understand why he did not take the appropriate action to have Rascher prosecuted for this premeditated murder. The fact of the matter is that Romberg merely reported this death to Ruff (Tr. p. 6932), and no appropriate action was taken by Ruff either. Although alleging an objection to this fatality, Romberg admits participation in the autopsy of the unfortunate victim. This autopsy clearly bore out the fact that air embolism was the cause of death. When asked if he participated in this autopsy, Romberg answered, “Yes, I watched one autopsy. That was my duty.” (Tr. p. 6924.) Romberg testified that he saw two other deaths and that air embolism also caused those. (Tr. pp. 6925-6.)

Ruff and Romberg lay great stress on the point that deaths are not mentioned in the joint report of 28 July 1942 of Romberg, Ruff, and Rascher. This, of course, is a very understandable omission, but it in no way proves that they are not responsible for those murders. Indeed, the joint report of 28 July 1942 (NO-402, Pros. Ex. 66) is identical with Rascher’s report of 11 May 1942 (NO-220, Pros. Ex. 61) except for the specific mentioning of the deaths. For example, paragraph 3 of the Rascher report is a summary of part III-1, pages 3 to 18, and part III-2, pages 18 to 19 of the joint final report. Paragraph 4 of Rascher’s report contains results set out in part III-4, pages 21 to 22, of the joint final report. Paragraph 5 of Rascher’s report is identical with part III-3, pages 19 to 21, of the joint final report. Paragraph 6 of the Rascher report where the pervitin experiments are mentioned is alluded to in the pervitin data in the joint final report on page 18. Paragraph 7 of the Rascher report contains the conclusions incorporated in the joint final report and gives details on the gas bubble data which are referred to on pages 16 to 18 of the joint final report, but from which is omitted reference to the autopsy results of the murdered prisoners. These various passages were compared by the witness Ivy and he concluded that they refer to the same subject matter. (Tr. p. 9097.)
