Friedrich Wilhelm Freiherr von Seydlitz (3 February 1721 – 8 November 1773) was a Prussian officer, lieutenant general, and among the greatest of the Prussian cavalry generals. He commanded one of the first Hussar squadrons of Frederick the Great's army and is credited with the development of the Prussian cavalry to its efficient level of performance in the Seven Years' War. His cavalryman father retired and then died while Seydlitz was still young. Subsequently, he was mentored by Margrave Frederick William of Brandenburg-Schwedt. Seydlitz's superb horsemanship and his recklessness combined to make him a stand-out subaltern, and he emerged as a redoubtable Rittmeister (cavalry captain) in the War of Austrian Succession (1740–1748) during the First and Second Silesian Wars.
