Sent by the Baden State Library Karlsruhe to the Karlsruhe General State Archive in a letter dated 29 April 1941. According to this letter, the documents came from the library of the Jewish doctor Dr. Wilhelm Rosenberg in Pforzheim (19.07.1870-09.12.1960), most of which had been taken over by the State Library. Dr. Rosenberg was deported to Gurs on 22.10.1940, survived and returned to Pforzheim in 1951. It was not possible to find out who the heirs of Wilhelm Rosenberg are who are entitled to restitution.
