Viola Spolin (November 7, 1906 — November 22, 1994) was a theatre academic, educator and acting coach.

 Her book "Improvisation for the Theater", which published these techniques, includes her philosophy and her teaching and coaching methods, and is considered the "bible of improvisational theater".
 Spolin's contributions were seminal to the improvisational theater movement in the U.S.
 She is considered to be the mother of Improvisational theater.
