After the so-called “Aryan Paragraph” of the “Law for the Restoration of the Professional Civil Service” of April 7, 1933 came into effect, members of certain professions were required to prove their “purely Aryan descent” in order to continue practicing their professions. The 38 year-old surgeon Dr. Walter Bernhard Kunze of Freiberg in Saxony was among those who had to fill in a form regarding his lineage for the “Aryan certificate.” The form, dated May 15, 1938, contains personal data reaching back to the generation of his grandparents. To the form, the corresponding documents from the civil registry office and the parish office had to be attached. Obtaining the numerous copies from the church and communal offices in the places of birth and residence of the grandparents often entailed a significant bureaucratic burden to the individual. The “Aryan certificate” was an effective tool of National Socialist racial policy by which persons seen as “non-Aryan” could be stigmatized and increasingly marginalized.
