Work in aerodynamic research; with Ludwig Prandtl (Universitt̃ Gt̲tingen) on supersonic speeds. Work on wing and turbine blade designs in Dresden, mid-1930s; discovers critical features of steady flow shock waves; builds "Busemann biplane" and presents it at the Volta Conference in Italy in 1935 (other presentations at Conference are discussed); Richard Whitcomb's airplane model. Early work on magneto-hydrodynamics, early 1920s, as well as his work on cylindrical focusing of shock waves and non-steady gas dynamics. Brought to England, 1946-1947; works in U.S. with NASA until 1964. Lifetime professorship at University of Colorado from 1964.
