“It has been established that the need exists, to test the efficiency of, and resistance of the human body to, the typhus serum extracted from egg yolks. Since tests on animals are not of sufficient value, tests on human beings must be carried out.” This entry preceded by only a few days the actual commencement of the experiments on concentration camp inmates to determine the efficiency of the egg-yolk vaccine. It seems certain that the foregoing entry in the Ding diary was written or rewritten at some date later than that which it bears, but the entry may be accepted as evidence of probative value to the fact that it was agreed by some persons in authority that experiments with vaccine prepared from egg yolks be made on concentration camp inmates at Buchenwald. The next entry in the diary bears date 2 January 1942, and reads as follows: “The concentration camp Buchenwald is chosen for testing the typhus serums. SS Hauptsturmfuehrer Ding is charged with these tests.” Handloser testified that many conferences concerning typhus vaccine took place and that he was interested in the testing of chicken-egg vaccine “on a sufficient number of persons in a certain vicinity, that is, within an area where typhus had already occurred or there was imminent danger existing.” He also testified that during the summer of 1941 he met Mrugowsky, who was recommended to him by Schreiber, Handloser’s subordinate. He also testified that he discussed the matter of the chicken-egg vaccines with Gildemeister and Conti. Handloser testified that he was present at many conferences, both at the front and in rear echelons, where such matters were discussed. Mrugowsky, in a letter dated 5 May 1942, reported to Eyer (who was a subordinate of Handloser) of the Typhus and Vaccine Institute of the High Command at Cracow [Krakow], describing the results of the first series of experiments carried out in Buchenwald. The experiments covered both the Weigl and egg-yolk vaccines. This report called attention to the fact that two experimental subjects had died. An entry in the Ding diary dated 8 February 1943 states that Dr. Eyer and Dr. Schmidt, a hygienist on the staff of the Medical Inspectorate, visited the Typhus and Virus Institute at Buchenwald. Schmidt, a subordinate of Handloser from 1942 until August 1944, stated that he and Eyer had visited Buchenwald. He testified that his visit was concerned only with yellow fever vaccine tests which were being carried out at that station. This statement by the witness is not convincing. From the Ding diary it appears that infected lice were received by Ding prior to 30 November 1942. If this is correct, these lice could have come only from an institute under control of the army over which Handloser had jurisdiction.
