Carl Wilhelm Hahn (8 June 1898 – 18 February 1982) was a German journalist, historian, archivist and head of the Schleswig-Holstein federal state’s so called Sippenamt (a state agency overseeing the archiving and analysis of family records, Sippe being a Nazi term for extended families) during the Nazi regime. As an active Anti-Semite, member of the NSDAP and the Sturmabteilung, he was of considerable importance for the implementation of the Nazi racist policy in Schleswig-Holstein and beyond. After the end of World War II, he quickly managed to gain a foothold again and to cover up his commitment to Nazi racial policy. As early as 1951 he was seconded to the press office of the state chancellery in Kiel, and from 1957 he worked again in the state archive of Schleswig-Holstein in Schleswig. Reaching his retirement age in 1963, he was recognized as a respected figure in local media.[1][2]
