William Wintershall (died July 1679), also Wintersall or Wintersell, was a noted seventeenth-century English actor.
According to James Wright's Historia Histrionica (1699), Wintershall's career began in the final years of the period of English Renaissance theatre; he was likely a young member of Queen Henrietta's Men at the Salisbury Court Theatre in the 1637–42 years.
During the theatre closure, 1642–60, Wintershall was one of the English actors who performed in Europe, mainly in The Hague and Paris, in the middle 1640s.
[3] In 1659 Wintershall and a Henry Eaton paid a bond for a court appearance by Anthony Turner, who was in legal trouble for violating the prohibition against acting.
Wintershall's stage career experienced a resurgence with the Restoration; he was one of the thirteen actors who were the original "sharers" (partners) in the King's Company under the management of Thomas Killigrew.
