Gwyneth Evelyn "Gwen" Verdon was an American actress and dancer. She won four Tony Awards for her musical comedy performances, and she served as an uncredited choreographer's assistant and specialty dance coach for theater and film. Verdon was a critically acclaimed performer on Broadway in the 1950s, 1960s, and 1970s, having originated many roles in musicals, including Lola in Damn Yankees, the title character in Sweet Charity, and Roxie Hart in Chicago.

Sweet Charity is a musical with music by Cy Coleman, lyrics by Dorothy Fields and book by Neil Simon. It was directed and choreographed for Broadway by Bob Fosse starring his wife and muse Gwen Verdon alongside John McMartin. It is based on the screenplay for the 1957 Italian film Nights of Cabiria. However, whereas Federico Fellini's black-and-white film concerns the romantic ups-and-downs of an ever-hopeful prostitute, in the musical the central character is a dancer-for-hire at a Times Square dance hall. The musical premiered on Broadway in 1966, where it was nominated for nine Tony Awards, winning the Tony Award for Best Choreography. The production also ran in the West End as well as having revivals and international productions.
