In 1934, he replaced Wolfgang Gaede as director of the physics department at the Technische Hochschule Karlsruhe (today, the Universität Karlsruhe); Gaede had been forced out by the National Socialist regime as “politically unreliable” after he accepted the Duddell Medal of the London Physical Society in 1933.
[1][2] Bühl was a physics advisor to the Nationalsozialistischer Deutscher Dozentenbund (NSDDB, National Socialist German University Lecturers League).
During the period in which Deutsche Physik was gaining prominence, a foremost concern of the great majority of scientists was to maintain autonomy against political encroachment.
This was, in part, due to political organizations, such as the NSDDB, whose district leaders had a decisive role in the acceptance of an Habilitationsschrift, which was a prerequisite to attaining the rank of Privatdozent necessary to becoming a university lecturer.
Alfons Bühl, a supporter of Deutsche Physik, invited Harald Volkmann, Bruno Thüring, Wilhelm Müller, Rudolf Tomaschek, and Ludwig Wesch.
