Funk was clearly distressed during the proceedings and cried during presentation of evidence such as the murders carried out in the Nazi concentration camps, and needed sleeping pills at night. Hjalmar Schacht relates that he, Funk and von Papen formed a close intimate circle at Nuremberg. He felt Funk was unable to comprehend the serious nature of the duties which he had undertaken. Schacht believed that there were many matters of which Funk had no knowledge whatsoever and that he gave a poor performance in the witness-box. However Albert Speer gave a different version of events. He said that when he first came into contact with Funk at Nuremberg "he looked extremely worn and downcast." But "Funk reasoned skillfully and in a way that stirred my pity" in the witness box.
