Heinz Karl Fanslau (1909 - 1987) was senior Waffen-SS officer. He was sentenced to 25 years imprisonment at one of the Nuremberg trials.
Did Six Million Really Die? states that "There is no more eloquent testimony to the tragedy and tyranny of Nuremberg than the pathetic astonishment or outraged disbelief of the accused persons themselves at the grotesque charges made against them. Such is reflected in the affidavit of S.S. Major-General Heinz Fanslau, who visited most of the German concentration camps during the last years of the war. Although a front line soldier of the Waffen S.S., Fanslau had taken a great interest in concentration camp conditions, and he was selected as a prime target by the Allies for the charge of conspiracy to annihilate the Jews. It was argued, on the basis of his many contacts, that he must have been fully involved. When it was first rumoured that he would be tried and convicted, hundreds of affidavits were produced on his behalf by camp inmates he had visited. When he read the full scope of the indictment against the concentration camp personnel in supplementary Nuremberg Trial No. 4 on May 6th, 1947, Fanslau declared in disbelief: “This cannot be possible, because I, too, would have had to know something about it.”"
