As a precaution let us also examine the question as to what further activity Sievers developed in connection with the low-pressure experiments. From the document book presented by the prosecution it appears that Sievers passed on letters which came to his office. Sievers is mentioned in some documents. The following separate letters are at hand: In connection with the altitude experiments, the prosecution’s document book contains the following documents in which the Reich Business Manager of the Ahnenerbe is mentioned in one way or another. (_NO-263, Pros. Ex. 47._) Letter from Frau Rascher to the Reich Leadership SS dated 24 February 1942: “Rascher requests SS Obersturmbannfuehrer Schnitzler to acquaint the Reich Leader with the events and to say at the same time that Rascher, as a member of the Ahnenerbe, definitely wishes to participate scientifically in the experiments.” From this it is seen how very keen even Frau Rascher was that her husband should participate in the experiments in Dachau. This was at a time when Sievers had as yet no knowledge at all of the altitude experiments. Letter from the Reich Business Manager of the Ahnenerbe to Dr. Brandt, dated 26 August 1942 (_NO-221, Pros. Ex. 68_). This letter contains a copy of a letter from Rascher which had as its subject a report by Rascher and Romberg to Field Marshal Milch. The second part of the letter contains the report and the assent to the publication of the scientific results. Here the date of the letter must be pointed out, 26 August 1942, which was many weeks after the altitude experiments had come to an end, in May 1942. Dr. Brandt’s reply to Sievers, dated 29 August 1942 (_NO-222, Pros. Ex. 69_): “The letter of the Reich Leader SS, with which he has forwarded the report to Field Marshal Milch, was only signed and sent off a few days ago. Copy of the letter of the Reich Leader SS dated 25 August 1942 is enclosed for your information.” Here it is to be observed that this letter likewise was written long after the conclusion of the altitude experiments and, like the preceding one, contains nothing at all concerning the experiments. It cannot be inferred from the letter dated 29 August 1942 that a copy of the report sent to Field Marshal Milch was also sent to the Ahnenerbe. Brandt sends Sievers a copy of his letter to Dr. Rascher dated 6 September 1942 (_NO-223, Pros. Ex. 71_). It contains the information that Field Marshal Milch will ask Dr. Rascher and Dr. Romberg to meet shortly and report. Letter from Rascher to Himmler, dated 9 October 1942 (_1610-PS, Pros. Ex. 73_). Sievers is mentioned in connection with the unsuccessful report to Milch. It is worth noting that Rascher asks that the low-pressure chamber may still be left at his disposal for further experiments.
