On 15 October 1946, a few hours before his execution, "Nazi No 2", the founder of the Gestapo, Hermann Göring, committed suicide. During his imprisonment at the Nuremberg Prison, Göring had kept a glass vial of cyanide hidden inside a brass .25-calibre cartridge. Initially, Göring's legal counsel, his wife, and his hairdresser were suspected of passing him the poison. An investigation by the allied powers concluded that Göring had hidden the cartridge even before his arrest. Göring left a suicide note:
"Nuremberg, 11 October 1946
To the Commandant
Since my imprisonment, I have always kept the poison capsule on my person. I had three capsules when I was committed to prison in Mondorf. The first one I left in my clothing so that it would be found in the search. The second I left under the coatstand while undressing and took it again when I dressed. I hid this in Mondorf and here in the cell so well that, in spite of the frequent and very thorough searches, it could not be found. During the trial, I kept it in my high riding boots. The third capsule is still in my little toilet case in the round container of skin cream (hidden in the cream). I had two opportunities to take the capsule in Mondorf, had I needed it. No one in charge of the searches was at fault, since it was almost impossible to find the capsule. It would have been purely by chance.
Hermann Göring
PS: Doctor Gilbert told me that the Control Council rejected the change in the manner of execution to death by firing squad".
