For the rest, Weltz’ name does not appear in any connection in any of the numerous documents relating to the problem of freezing experiments submitted by the prosecution. On the contrary, these documents show clearly who from the Luftwaffe was actually ordered to carry out these experiments and who carried them out in Dachau. The fact that Professor Weltz was not even requested to participate in the planning of the freezing experiments, appears clearly from Document NO-283, Prosecution Exhibit 82, already discussed, and above all without objection. * * * * * That Professor Weltz refused to participate in the experiments after he learned about them was firmly established on the other hand by the evidence submitted by the defense which in turn is supported by the documents submitted by the prosecution. Document 1610-PS, Prosecution Exhibit 73, submitted by the prosecution appears to have special weight as evidence in this connection. It is Rascher’s letter to Himmler of 9 October 1942. In this letter Rascher asks Himmler to see to it that the apparatus necessary for chemical analysis be put at his disposal by laboratories not working to full capacity. He points to the fact that the Weltz Institute does not make apparatus available to him, as it was allegedly used there for freezing experiments with shaved cats, and the institute needed these apparatus for its own use. Moreover, the affidavit of the witness Dr. v. Werz (_Weltz 4, Weltz Ex. 11_) according to which Professor Weltz refused to furnish apparatus for freezing experiments at Dachau, further proves this disapproval on the part of Professor Weltz of the freezing experiments carried out at Dachau. Moreover, it appears also from NO-3674, Prosecution Exhibit 549. Here, an attempt is made to procure the apparatus (colorimeter) which was not delivered by Weltz from somewhere else. From 1609-PS, Prosecution Exhibit 92, it becomes apparent to what danger Professor Weltz exposed himself by his attitude against Rascher. It is a letter of the Reich Leader SS of 24 October 1942 to Rascher. In it Himmler acknowledges the receipt of Rascher’s letter, dated 9 October 1942, (_1610-PS, Pros. Ex. 73_) mentioned above in which Rascher complains about Professor Weltz’ attitude. In reply to this complaint Himmler writes: “People who today still disapprove of human experiments and would rather have German soldiers die of the consequences of freezing I consider to be guilty of treason and high treason, and I shall have no compunction to report the names of these gentlemen to the authorities concerned. You are authorized by me to inform the offices concerned of this of my opinion.”
