Forcing Jews to wash the street

At the time of the Anschluss, Walter Nitsche was 20 years old and a student at the Höhere Staats-Gewerbeschule at Schellinggasse 13 in Vienna's 1st district. He graduated from school in June 1938 and shortly thereafter took up a job as a local construction supervisor at the "Road Administration of the Province of Lower Austria." At the end of November 1938, he was drafted into the Wehrmacht. Walter Nitsche became an American prisoner of war in 1944, from which he was released on June 1, 1946. It is unlikely that Nitsche was a member of the NSDAP or one of its sub-organizations. Research in this regard in archives and private documents was fruitless and nothing is known about this within the family. "Reibpartie", a man (Jew?) is forced to wash the street.
