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
Clayton Aniline Company new vat dyes complex (buildings 188, 189 and 190). The completion of the vat dyes project was held up by the outbreak of war in 1939. In 1940, a new Ministry of Supply factory (building 300) was constructed adjacent to the site for the manufacture of explosives additive Centralite I. The company also gained an important contract to manufacture monomethylaniline used as an antiknock agent in high octane aviation fuel. In 1941, a new aniline plant was built with an output of around 100 tons per week. On 5 October 1942, a near catastrophe befell the site when an ethylation
