1910–1911. This topic is once again, after 100 years, a very active research area.
Askenasy was Jewish and was forced to leave the faculty in 1933. He was followed
in 1933 by Friedrich August Henglein [7].
Other interesting facts from this Karlsruhe period should be noted: Staudinger
studied insecticides between 1910–1916 with Leopold Ruzicka, and Paul Immerwahr
financially supported this study [8]. After 1916, Staudinger developed synthetic
pepper substitutes in Zurich together with Paul Immerwahr. Paul Immerwahr was
the brother of Clara Immerwahr, who was Fritz Haber’s wife [9]. In 1915, Clara
Immerwahr committed suicide in Berlin after a large poison gas attack on France by
Germany in WWI because Haber was integrally involved in the technical development of poison gas warfare. This led to a major conflict in the friendship between
Staudinger and Haber. It should further be noted that Kurt Hans Meyer, with whom
Staudinger later had a substantial scientific dispute, was indirectly connected to
Karlsruhe because Meyer worked under Haber from 1917 on poison gas warfare in
Berlin.
