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
Aniline leather Aniline leather Aniline leather is a type of leather dyed exclusively with soluble dyes. The dye colours the leather without producing the uniform surface of a topcoat paint or insoluble pigmented sealant. The resulting product retains the hide's natural surface. Any visible variations on the surface of the undyed leather such as visible pores, scars, or other blemishes will remain visible. For this reason, only high quality leather is suitable for aniline finishing. Originally, the dyes used for this process were synthesized from aniline through chemical reactions. These dyes used to be called 'aniline dyes' or 'tar dyes'. In modern
