Friedrich Wilhelm von Steuben, Prussian-American general (b. 1730)
Friedrich Wilhelm August Heinrich Ferdinand von Steuben (born Friedrich Wilhelm Ludolf Gerhard Augustin Louis von Steuben; September 17, 1730 – November 28, 1794), also referred to as Baron von Steuben (German: [fɔn ˈʃtɔʏbm̩]), was a Prussian military officer who played a leading role in the American Revolutionary War by reforming the Continental Army into a disciplined and professional fighting force. His contributions marked a significant improvement in the performance of American troops, and he is subsequently regarded as one of the fathers of the United States Army.Born into a military family, Steuben was exposed to war from an early age; at 14 years old, he observed his father directing Prussian engineers in the 1744 siege of Prague. He enlisted in the Prussian Army at age 16 or 17, which was considered the most professional and disciplined in Europe. During his 17 years of military service, Steuben took part in several battles in the Seven Years' War (1756–63), rose to the rank of captain, and became aide-de-camp to Prussian King Frederick the Great, who was renowned for his military prowess and strategy. Steuben's career culminated in his attendance of Frederick's elite school for young military officers, after which he was abruptly discharged from the army in 1763, allegedly by the machinations of a rival.Steuben spent 11 years as court chamberlain to the prince of Hohenzollern-Hechingen, a small German principality. In 1769, the Duchess of Wurttemburg, a niece of Frederick, named him to the chivalric Order of Fidelity, a meritorious award that conferred the title, Freiherr, or "free lord"; in 1771, his service to Hollenzollern-Hechingen earned him the title baron. In 1775, as the American Revolution had begun, Steuben saw a reduction in his salary and sought some form of military work; unable to find employment in peacetime Europe, he joined the American war effort through mutual French contacts with American diplomats, most notably ambassador to France Benjamin Franklin. Due to his military exploits, and his willingness to serve the Americans without compensation, Steuben made a positive impression on both Congress and General George Washington, who appointed him as temporary Inspector General of the Continental Army.

Appalled by the state of American forces, Steuben took the lead in teaching soldiers the essentials of military drills, tactics, and discipline based on Prussian techniques. He wrote Regulations for the Order and Discipline of the Troops of the United States, which remained the army's drill manual for decades, and continues to influence modern U.S. army manuals. Steuben also addressed widespread administrative waste and graft, helping save desperately needed supplies and funds. Impressed by these results, which began bearing fruit on the battlefield, in 1778, Congress, on Washington's recommendation, commissioned Steuben as Inspector General with the rank of Major General. He served the remainder of the war as Washington's chief of staff and one of his most trusted advisors.After the war, Steuben was made a U.S. citizen and granted a large estate in New York in reward for his service. In 1780, he was elected a member of the American Philosophical Society, a learned society that included most of the nation's most prominent founding fathers.
