In 1903 after graduation, Moss became an engineer for General Electric's[1] Steam Turbine Department in Lynn, Massachusetts.
[3] In autumn of 1917 William F. Durand, Director of the National Advisory Committee for Aeronautics, received incomplete reports that a French engineer named Auguste Rateau was attempting to develop engines for high altitudes using a turbo-driven air compressor.
[4] Moss built a high-RPM supercharger, driven by engine exhaust flow, and tested it in 1918 at Wright Field in Dayton, Ohio.
Later in 1918 Moss attached his turbo-supercharger to a Liberty V-12 aero engine and tested it near Pikes Peak.
After his retirement from GE in 1938, Moss was awarded the Collier Trophy, presented by the National Aeronautic Association in 1940 for his work on the turbocharger.
