Karl von Spruner (November 15, 1803 - August 24, 1892) or Spruner Karl von Merz or Spruneri was a Stuttgart born cartographer, scientist, and map publisher active in Germany during the middle part of the 19th century. Joining the Bavarian army at the tender age of 11, Spruner dedicated most of his life to military service. Spruner's superiors, recognizing his keen intellect, eventually assigned him to the army's cartographic division. Military education earned him the title of Doctor of Cartography in 1852. In 1855 he attained the rank of Lieutenant-Colonel and, in 1883, General. Cartographically, Spruner is best known for his historical atlases, most of which were published by the Justus Perthes firm. His much admired maps studiously applied historical political geographies to contemporary physical geographies. Spruner also worked with Heinrich Theodore Menke, a well-known German mapmaker, to produce and later revise his many historical maps. In 1886, after 72 years of professional military service, Spruner formally retired. He died seven years later in Munich in on August 24th of 1892.
