List of Famous people named William

Captain William Winde (c.1645–1722) was an English gentleman architect, whose Royalist military career, resulting in fortifications and topographical surveys but lack of preferment, and his later career, following the Glorious Revolution, as designer or simply "conductor" of the works of country houses, has been epitomised by Howard Colvin, who said that "Winde ranks with Hooke, May, Pratt and Talman as one of the principal English country house architects of the late seventeenth century".

William Alanson White was an American neurologist and psychiatrist.

William Marbury was a highly successful American businessman and one of the "Midnight Judges" appointed by United States President John Adams the day before he left office. He was the plaintiff in the landmark 1803 Supreme Court case Marbury v. Madison.
