the date last mentioned the chain of military command in the field of hygiene and research was as follows: Himmler - Grawitz - Genzken - Mrugowsky - Ding.
Prior to 1939 Ding had been camp physician at Buchenwald, and as such was subordinate to Genzken. During the early months of the war Genzken served as an army surgeon in the field, Ding being his adjutant. During the fall of 1941 Ding returned to Buchenwald and Genzken to his office at Berlin. During their service in the field Genzken and Ding had become warm personal friends. Ding was attached to the Hygiene Institute of the Waffen SS and was engaged in typhus research for the Institute. Genzken testified that Mrugowsky and the Hygiene Institute were in his chain of command prior to 31 August 1943. He further testified that after the date last mentioned his office had nothing to do with Ding save to provide money for Ding's expenses, there being no other budget from which money was available. Mrugowsky testified that Genzken was his superior officer until 1 September 1943, and knew that the Hygiene Institute was working on the problem of providing an efficient vaccine against typhus. It is admitted that Ding was carrying out medical experiments on concentration camp inmates in order to determine the effect of various typhus vaccines.
It is not contended that such experiments were not carried out. In the course of these experiments two buildings or "blocks" were used. The experiments were conducted in Block 46, and when satisfactory vaccine was decided upon, Block 50 was used for the preparation of vaccines.
During the course of the experiments with vaccines in March 1942, Ding himself contracted typhus. Genzken testified that he was aware of the fact that concentration camp inmates were subjected to experiments, but stated that he was not advised as to the method of experimentation.
It is clear that the experiments necessary to decide upon a satisfactory vaccine preceded by a considerable period the production of the vaccine. Genzken testified that vaccine production began in December 1943, that the production establishment only moved into Block 50 in the middle of August, and that when production actually began "this establishment had already come under the agency of Grawitz and it was not subordinated any more" to him.
Under date of 9 January 1943 the Ding diary contains a lengthy entry stating that by Genzken's order the typhus research station became the "Department of Typhus and Virus Research," that Dr. Ding would be head of this department, and that during his absence defendant Hoven would act in his place.
