Stöhr was a Sudeten German who had been active in antisemitic politics before the First World War.
[1] Stöhr was elected member of the Reichstag for Thuringia in May 1924 and retaining his seat until his death.
However, in May 1927 Ernst Graf zu Reventlow split from the DVFP after becoming a strong admirer of Adolf Hitler and Stöhr joined the likes of Christian Mergenthaler and Wilhelm Kube in following Reventlow into the Nazi Party.
[3] He was also a leading figure in the Deutschnationaler Handlungsgehilfen-Verband, a völkisch and antisemitic trade union for white-collar workers, close links with which had been cultivated by Gregor Strasser in the early 1930s.
[4] He was a shop-assistant by profession and thus of the petit-bourgeois stock that made up the bulk of Nazi Party support in the 1920s.
