Already the programme of the publication series Deutsche Musikbücherei showed a strictly anti-modernist, German-national orientation.

After the war I was often active in the national struggles for a new Germany. In 1919 I was co-founder of the Citizens' Bloc and later co-founder and district leader of the Resident Army. I was also a founding member of the local branch of the German Officers' Association. In 1920/21, together with Prof. Dr. Wiedenbauer, I founded the local group of the Deutschnationale Volkspartei, of which I was a member of the board until 1933. The foundation of the NSDAP here in 1922 by Mr. Reiter was supported by me in word and deed. At the same time I became chairman of the in Regensburg. In the decisive battles before 1933 I presented the Gauleiter of that time my printing house for the printing of the Gauamtliche Kampfzeitung Schaffendes Volk. I supported this struggle to the utmost by giving out the largest loans, which severely strained my own means, so that at the end of 1932 - beginning of 1933 I myself came into a very difficult situation by the straining of my bank loans and the loans of my suppliers. In this difficult situation the Fuhrer himself intervened at that time by providing assistance through Rudolf Hess and through an envoy of Hitler's Chancellery, Mr. Stark.
