Heinz Guderian

Heinz Wilhelm Guderian (German: [haɪnts ˈvɪlhɛlm ɡuˈdeːʁi.an]; 17 June 1888 – 14 May 1954) was a German army general and military theorist. A pioneer and advocate of what would come to be called the "blitzkrieg" approach, he played a central role in the development of the panzer division concept and tank warfare more broadly.

In 1936, after serving in the military since leaving school, including in World War I, he was promoted to Heer Generalmajor (Major General) and became the Inspector of Motorized Troops. At the beginning of World War II, Guderian led an armoured corps in the Invasion of Poland with the rank of General der Panzertruppe. During the Invasion of France, he commanded the armoured units that attacked through the Ardennes forest and overwhelmed the Allied defenses at the Battle of Sedan. He led the 2nd Panzer Army with the rank of Generaloberst (Colonel General) during Operation Barbarossa, the invasion of the Soviet Union. The campaign ended in failure after the German offensive Operation Typhoon failed to capture Moscow, and after a disagreement with Hitler, Guderian was dismissed.

In early 1943, Adolf Hitler appointed Guderian to the newly created position of Inspector General of Armoured Troops. In this role, he had broad responsibility to rebuild and train new panzer forces but saw limited success due to Germany's worsening war economy. Guderian was appointed Acting Chief of the General Staff of the Army High Command, immediately following the 20 July Plot to assassinate Hitler.
