And....
The length of time it took doctors to pronounce the men dead once they had been hanged:
Foreign Minister Joachim von Ribbentrop -18 minutes
Field Marshal Wilhelm Keitel - 24 minutes
SS General Ernst Kaltenbrunner - 13 minutes
Minister Afred Rosenberg -10 minutes
Governor General of Poland Hans Frank -10.5 minutes
Minister of the Interior Wilhelm Frick -12 minutes
Anti-semitic newspaperman Julius Streicher - 14 minutes
Slave labour chief Fritz Sauckel - 14 minutes
General Alfred Jodl - 16 minutes
Arthur von Seyss-Inquart, governor of the Netherlands and Austria - no time cited

the apparent delay was the product of a decision to construct three sets of gallows - two for the executions themselves and one spare - and to hang the condemned Nazis one after the other, but on two different gallows. The doctors present did not enter the enclosed areas beneath the traps to pronounce one hanged men dead until the man on the adjacent gallows had also been hung; thus, after Ribbentrop and Keitel had both dangled, they pronounced Ribbentrop dead; then Kaltenbrunner was hung on Ribbentrops gallows while Keitel was still strung up, after which Keitels body was cut down and examined, and so on. This was the cause of the apparent delay in pronouncing death.
In one case, however, the hanged man appears to have died of strangulation and not of a broken neck. Perhaps fittingly, the man in question was Julius Streicher the odious editor of the racist newspaper Der Sturmer, and the only one of the condemned who went to his death still shouting "Heil Hitler".
