“Rose”
The signature which you see on this photostatic copy is, in effect, my signature. This letter shows that I also informed Mrugowsky about the Copenhagen vaccine, which I did not remember up to this point.
Q. And you asked him to test the vaccine in Buchenwald didn’t you?
A. The question of whether this vaccine can be tested in Buchenwald is dealt with here.
Q. Do you see the name “Ding” written at the bottom of the letter?
A. Yes, it is at the bottom of the page.
Q. And it appears that the testimony of Kogon was very precise, wasn’t it, because Ding got a copy of this letter, didn’t he?
A. Yes. Ding’s utterances do not only refer to my memorandum but also to the correspondence between Mrugowsky and myself. Apparently it was then transferred to the Reichsarzt SS.
Q. Is the date on this letter 2 December 1943 or 12 February 1943—and I direct your attention to the receipt stamp on the letter which is 21 February 1944?
A. The difference between the two dates can be explained by the fact that a considerable time had elapsed between the sending of my letter and when this letter finally reached Ding. During this time the competent agency dealt with the matter of the approval and execution of the experiments on human beings.
