Reich Leader:
The Chief of the Technical Office in the SS Administrative Main Office, SS Gruppenfuehrer Schwab, contacted me in September of this year with the request to furnish him with two doctors, who as medical experts were to witness experiments with N-substance, which he was carrying out at the time by order of the Fuehrer. This was above all a matter of the clarification of the question whether N-substance was to be considered for chemical warfare or not.
For this purpose I have furnished my leading pathologist, SS Hauptsturmfuehrer University Teacher Dr. Sachs, as well as the doctor working on the Ahnenerbe, SS Hauptsturmfuehrer University Teacher Dr. Ploetner.
In accordance with the experiments carried out on 25 September 1944, the necessity has now arisen to carry out several experiments on human beings for the final clarification of the physiological effect of N-substance on and through the human skin. Five prisoners are necessary for the execution of these experiments. It is highly improbable that the experiments will cause any permanent damage.
In accordance with your order of 15 May 1944, Reich Leader, I have obtained the opinion of SS Gruppenfuehrer Professor Gebhardt, SS Gruppenfuehrer Gluecks, and SS Oberfuehrer Panzinger. They read as follows:
1. SS Gruppenfuehrer Professor Dr. Gebhardt
“I am certainly in agreement with suggestion, and request that the directions for the supervision of the experiments be issued directly by the Reich Physician SS and Police.”
2. SS Gruppenfuehrer Gluecks
“I have received your letter of 7 November 1944 with regard to the procurement of five prisoners for the experiments which are to be carried out with N-substance.
“For this purpose I have had five prisoners in the Sachsenhausen concentration camp who have been condemned to death placed in readiness, on whom these experiments can be carried out.”
