William Windham, FRS was an English landowner and writer. The son of Ashe Windham and Elizabeth Dobyns, he made an extensive Grand Tour of Europe in his youth, accompanied by his tutor, Benjamin Stillingfleet; the pair left England in 1737. During 1740–1741, Windham and Stillingfleet were members of a circle of British expatriates known as The Common Room. The circle lived in Geneva, and amused themselves with amateur theatricals.
