“After having thoroughly examined all typescripts from Erna Petra Hitler I conclude that those documents are authentic. For the simple reason that the typewriter that had been used or the highest possible age of the typewriter that had been used is not in conflict with the dating.”
Paraphrase of a quote of Bernhard Haas taken from the ZDF History documentation about Hitler’s family.
