オットー・シュトラッサー
Multiple authors and eyewitnesses, such as Konrad Heiden and Nazi "apostate" Otto Strasser, report that not only did Stempfle correct the galley proofs of "Mein Kampf", but that he indeed copy-edited certain passages. Historian and Hitler biographer Alan Bullock likewise discusses this. (See the German version of this Wikipedia entry for more details.)
