Walter Kreiser

Walter Kreiser (10 February 1898 – 1958) was a German aircraft designer and journalist best known for publishing an article in the magazine Die Weltbühne (‘The World Stage’) in 1929 which exposed the secret creation of a German Air Force in violation of the Treaty of Versailles. Its publication resulted in him being convicted in 1931 of espionage in the Weltbühne Trial.  He and future (1935) Nobel Peace Prize winner Carl von Ossietzky received 18 months in prison.
