The Nazis’ persecution of Jews began in April 1933 with the “Law for Restoration of the Professional Civil Service” that deemed “politically unreliable” employees unfit to serve. This later developed into both state and federal laws that excluded Jews and other non-Aryans from certain professions, organizations, academic institutions, and areas of social life and the arts, including performing on stage or on screen. The Nuremberg Laws, legally prohibiting social and personal contact between Jews and non-Jews, were a particularly important part of this process.
Professional and other organisations also passed anti-Jewish measures ahead of laws requiring them to do so, a process known as [cumulative radicalisation].
[cumulative radicalisation: a term coined by the German historian Hans Mommsen to describe how German businesses, professional organisations and even localities exceeded the directives of the Nazi regime in excluding Jews from German society.]
