Due to social and official discrimination, though, most of their stories have gone untold. But in the case of one of the military’s founding heroes, homosexuality was always part of the story.

Baron Friedrich von Steuben, a Prussian military man hired by George Washington to whip the Continental Army into shape during the darkest days of the Revolutionary War, is known for his bravery and the discipline and grit he brought to the American troops. Historians also think he was homosexual—and served as an openly gay man in the military at a time when sex between men was punished as a crime.
