Gerhard von Scharnhorst, Prussian general and politician, Prussian Minister of War (died 1813)

Gerhard Johann David von Scharnhorst was a Hanoverian-born general in Prussian service from 1801. As the first Chief of the Prussian General Staff, he was noted for his military theories, his reforms of the Prussian army, and his leadership during the Napoleonic Wars. Scharnhorst limited the use of corporal punishments, established promotion for merit, abolished the enrollment of foreigners, began the organization of a reserve army, and organized and simplified the military administration.

The Prussian Ministry of War was the highest state authority of the Royal Prussian Army and was responsible for the central administration of the army of the Kingdom of Prussia and, later, the Imperial German Army. The ministry existed from 1808 through the establishment of the German Empire and was dissolved in 1919, being succeeded by the Ministry of the Reichswehr.
