Gottfried Guderley studied from 1928 to 1934 and submitted a PhD thesis at Technical University of Dresden, where he had collaborated with Constantin Weber (1885-1976). Guderley obtained in 1943 his habilitation thesis from the Braunschweig Technical University, where he had collaborated with Hermann Schlichting (1907-1982). He was at the Luftfahrt-Forschungsanstalt of Braunschweig from 1938 to 1945 and in 1946 emigrated to the USA, where he continued works at Dayton OH. In 1955 he received the Thurman H. Bane Award from the Institution of Aeronautical Sciences. This award is annually presented to persons with outstanding achievements in aeronautical developments. Guderley received the award for "his outstanding contributions to the development of transonic aerodynamics essential to the engineering design of supersonic aircraft". Guderley was from 1961 to 1974 a Senior Scientist of the Aerospace Research Laboratories in Dayton, OH.

During Guderley's stay in Braunschweig, he collaborated with Adolf Busemann (1901-1986), the father of supersonic flight. There he developed the method of characteristics for both plane and axis-symmetrical flow configurations. His approach was simpler and more general than others by then available. He took particular interest in the problem of flow around sharp corners, and his approach was finally verified to be in agreement with observations. Guderley's similarity law for transonic flows was derived in 1945 but published only later due to the chaotic conditions in Germany. Guderley continued research in transonic gas dynamics in the USA and presented a standard book in 1957.
