about the trial. A man by the name of Koehler, a Hauptscharfuehrer in Buchenwald, was arrested by Dr. Morgen and kept in custody in the Buchenwald concentration camp. This Hauptscharfuehrer seemed to have testified against Koch. Two or three days later this Hauptscharfuehrer Koehler was found dead in his cell. A few hours before he had been quite healthy. He seemed to have taken strong poison. Dr. Morgen contended that Dr. Hoven, together with the guard, Hauptscharfuehrer Sommer, had killed Koehler. Koehler was dissected in the dissecting room in the presence of a scientist from Jena and two of my comrades. The head of the pathology section was also present. Drugs of the alkaloid series were found in the stomach of the dead man. The amount and the specific type was not known. In order to determine the fatal dosage of poisons of this type, the SS court ordered an experiment on four Russian prisoners of war. This is the experiment which I have just described in Block 46. On 20 September 1943, Dr. Haven was arrested on Dr. Morgen's orders and remained in the custody of the SS court until the end of March 1945. I know the date exactly because on that Saturday afternoon Dr. Haven came to Block 50 on his motorcycle, asked me about Dr. Ding-Schuler, who, was not there, and went away again quite depressed. Half an hour later I learned from the hospital, the prisoners' hospital, that Dr. Hoven expected to be arrested himself.
Q. In other words, Hoven was suspected by Morgen of having done away with the witness against Koch, is that right?
A. Yes.
Q. Now, will you explain to the Tribunal about his second poison experiment?
A. In the summer of 1944 — I am not quite sure of the exact date — Dr. Ding, who was already called Schuler, came from Berlin at the time and told me that he had a very unpleasant task to perform. He said it was extremely secret and a few hours later, without my having asked, he told me details about it in his room.
I must point out that at this time there was really nothing at all private or official, that Dr. Schuler would not have told me in order to get my advice. He realized quite clearly that the cause of National Socialism was lost. He was only looking for safety.
He said, "Kogon, can you see any way of getting me out of this affair? I am supposed to test a poison here on Russian prisoners of war. I have to report on it immediately. It is a direct order from Mrugowsky. I don't know how I can get out of it."
He gave me the prescription, the chemical formula of this poison, and I was to put this prescription in an envelope and seal it in his presence. In my haste I was not able to read it. It had some code name. I put the prescription in the envelope and only said to him,
