Dr. Wilhelm Binder (geb. Katzenbeisser)

Wilhelm Katzenbeisser graduated from Stockerau grammar school in 1918. After brief military service in the First World War, he studied to become a teacher at the University of Vienna and joined the Viennese student fraternity Babenberg in 1918. He completed his studies in June 1923 with a teaching degree and a doctorate (Dr. phil.). He worked as a prefect, professor and convict administrator at the Federal Teacher Training College in St. Pölten until 1938. During this time, together with Julius Kallus and Hermann Käfer, he published the "Lehrbuch der Geschichte für Lehrer- und Lehrerinnenbildungsanstalten", which was later banned by the National Socialists.

After the Anschluss, he was dismissed from the teaching profession and spent seven weeks in protective custody. After working as a scribe and assistant teacher, he was drafted into the German Wehrmacht in 1944 and was taken prisoner of war by the Americans, from which he was released in 1945.
