"Wolfgang Kreher Johannes "John" Graudenz (12 November 1884 – 22 December 1942) was a German journalist, press photographer, industrial representative and resistance fighter. Graudenz was most notable for being an important member of the Berlin-based anti-fascist resistance group that would later be named by the Gestapo as the Red Orchestra and was responsible for the technical aspect of the production of leaflets and pamphlets that the group produced." - (en.wikipedia.org 11.08.2021)
