During spring and summer 1933, numerous members of Hitler's opposition, the Social Democrats and Communists, were imprisoned at Hohenasperg. Amongst these prisoners was the Governor of Württemberg, Eugen Bolz, who was murdered during Aktion Gitter in Berlin in 1945. At least 101 prisoners died in Hohenasperg under its hard penal system, and 20 of their names have been identified by the Ludwigsburg VVN, an antifascist organization. These names are remembered on a plaque in the Prisoner's Cemetery.Gedenkstätten für die Opfer des Nationalsozialismus. Eine Dokumentation, Bd.I, Bonn 1995, S. 20f.,
