HANS GEBELEIN (1907-1985) was a German mathematician and physicist, specializing in hydrodynamics and aerodynamics. Working with the Luftfahrtforschungsanstalt Hermann Göring during the war, he was recruited afterwords into aircraft development for the British RAF and the U.S. Army. OTTO WILLI GAIL (1896-1956) studied electronics and physics, and then turned his knowledge into a career writing technical books and reporting on science in newspapers and radio broadcasts. He was acquainted with Austrian rocketry pioneer MAX VALIER (1895-1930) as well as Hermann Oberth. His utopian novels reflected his technical knowledge, and were highly detailed.
