Devrient as Hitler's voice coach.
According to Devrient's diary, published posthumously in 1975, he was supposed to provide relief after Hitler was diagnosed with impending vocal cord paralysis due to overexertion. For a fee, Devrient accompanied Hitler on his propaganda trips across Germany from April to November 1932. Devrient not only trained Hitler's voice and speaking technique, but also improved his presence as a political speaker in front of large audiences through acting and rhetoric lessons. In order not to undermine Hitler's credibility or even expose him publicly to the ridicule of his opponents, Devrient had to work under the utmost secrecy. Details only became known after his death, when his diary passed into the hands of his son Hans Stieber (born 1917). He left the records to Werner Maser, who finally published them in 1975.
Jens Dobler suspects that this diary and the entire Devrient-Hitler legend could be an invention by Hans Stieber, whom he also believes to be the presumed author of the forged memoirs of his great-grandfather Wilhelm Stieber published in 1978.
Devrient's cooperation with Hitler provided material for several stage plays and films. A first parody was delivered by Bertolt Brecht with the stage play "The Resistible Rise of Arturo Ui" (1941). George Tabori made the instructor into a man in the farce "Mein Kampf" (1987), he turned the instructor into a Jew who becomes his pupil's first victim. In the cinema comedy "My Führer – The Really Truest Truth about Adolf Hitler" (2006), director and writer Dani Levy has the German dictator taught by a Jewish concentration camp prisoner.
Devrient died in Ruhpolding at the age of 82.
