The beginnings of Hans Benders career in Bonn, Freiburg and Strasbourg coincided with the rise of National Socialism. After he had habilitated in 1941 with his work “Experimental Visions” at Erich Rothacker in Bonn, he became associate professor for general and clinical psychology at the newly established Reichsuniversität Strassburg due to his psychological and medical double qualification. With the help of so far unknown archive materials from Berlin, Bonn, Colmar, Freiburg, Koblenz, Marbach, München, Nürnberg, Stuttgart and Tübingen this study traces Benders career very closely, until the end of the Reichsuniversität Straßbußburg in November 1944. A CD-ROM with over 70 images of documents, persons and public, a résumé in French, a comprehensive bibliography, several registers and the first edition of Bender’s article in the commemorative publication of 1983 contributed to Rothacker carrying the title “Der Bewusstseins- und Erlebnisbegriff bei Klages und seine Brauchbarkeit für den Aufbau einer Halluzinationstheorie” (Klage’s concept of consciousness and experience and its usefulness for constructing a theory of hallucination) , completes the publication.
