Walter Weizel "Ruprecht-Karls-Universität Heidelberg". He received his doctorate in physical chemistry at Heidelberg, under Max Trautz. He switched form chemistry to physics to work on the quantum mechanics of molecules as a fellow of the "Notgemeinschaft der Deutschen Wissenschaft" (NG; Emergency Association of German Science) at the "Universität Rostock". He completed his Habilitation in 1929. After Habilitation, Weizel worked briefly at "Badische Anilin- und Sodafabrik" (BASF, Baden Aniline and Soda Factory) at Ludwigshafen. Then, during 1931, he had a Rockefeller fellowship to the University of Chicago. From late in 1931, Weizel was an "ordentlicher Professor" (ordinarius professor) of theoretical physics at the
