"Gerhard Johann David von Scharnhorst (12 November 1755 – 28 June 1813) 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." - (en.wikipedia.org 11.01.2021)
