On August 17, 1938 the German Reichstag passed a law1 requiring that German Jews be given only names that were listed as 'Jewish' by the directives of the Reich Ministry of the Interior, thus effectively forbidding Jews to take 'Aryan' names. The law also required all living German Jews whose given names were not listed as 'approved' given names to assume an additional given name. The order came into effect on January 1st, 1939.
For females, the required additional given name was Sara. For males, the required name was Israel.
This law was followed by the much more infamous "Police Decree Concerning the Marking of Jews" which established the
law requiring Jews to wear Star of David badges in public.
The Ministry of the Interior's list of approved "Jewish" given names follows below.
