Heidemann, Henke, and Oldenhage were summoned by the Wiesbaden police, to whom they had submitted some parts of Hitler’s diaries for authentication; the police informed them that at least 6 of the 9 documents in their possession were fakes due to the typewriter used (produced only in 1956) and the whitening agent found in the paper: Blankophor, produced by Bayer only after the Second World War; but the journalists at Stern did not even suspect that the diaries could be fakes: they thought it was an error in the examination of the material.
