Walther Kadow (1860 – 31 May 1923[1]) was a German school teacher who was murdered by Rudolf Höss and a group of Nazi Party accomplices in May 1923 in the forest near Parchim. Kadow was member of the rightwing German Völkisch Freedom Party, and was suspected of having betrayed German nationalist Albert Leo Schlageter to the French occupation authorities in the Ruhr. Schlageter was executed by the French and was later regarded as a martyr by the Nazis.
