Ludwig Hahn

As a senior officer of the ''Sicherheitspolizei'' (Security Police) and ''Sicherheitsdienst'' (Security Service) in occupied-Poland, Hahn was directly involved in the liquidation of the Warsaw Ghetto (July–September 1942) and the brutal suppression of both the Warsaw Ghetto Uprising (April–May 1943) and the Warsaw Uprising (August–October 1944).
During postwar investigations against him, Hahn was imprisoned from July 1960 to July 1961 and December 1965 to December 1967. Between 1972 and 1975, Hahn was the subject of two separate war crimes prosecutions in Hamburg, West Germany; both related to atrocities that occurred during his service with the SS in Warsaw. He was ultimately convicted and imprisoned from 1975 to 1983. Provided by Wikipedia
