Hans Karl von Winterfeldt (4 April 1707 – 8 September 1757), a Prussian general, served in the War of the Polish Succession, the War of Austrian Succession, Frederick the Great's Silesian wars and the Seven Years' War. One of Frederick's trusted confidantes and advisors, he attracted enmity from other courtiers. Frederick entrusted him with considerable autonomy on the general staff, and Winterfeldt developed the first "modern" program of military intelligence gathering. He negotiated the Convention of Westminster and, for his efforts on Frederick's behalf, received the Order of the Black Eagle and the Order Pour le Mérite. He died from wounds received at Battle of Moys. His name is included on the Equestrian statue of Frederick the Great.
