Ernst Volckheim (11 April 1898 – 1 September 1962) was one of the founders of armored and mechanized warfare. A German officer in the First and Second World War, Volkheim rose to the rank of a German Lieutenant Colonel, during World War II in the German Army. Little known outside of professional military and historical circles, Volkheim is considered the foremost military academic influence on German tank war proponent, Heinz Guderian, because both Volkheim's teaching as well as his 1924 professional military articles place him as one of the very earliest theorists of armored warfare and the use of German armored formations including independent tank corps.
