About Margaret McEntee
Margaret C. McEntee SR. SC., also known by her confirmation name Marita James, is an American Catholic religious sister and educator who is known as being the inspiration for the character of Sister James in the Pulitzer Prize and Tony Award-winning play Doubt: A Parable by John Patrick Shanley. The 2008 film adaptation is dedicated to her. Later in her career it became acceptable for nuns to use their baptismal name, so she reverted to using the name Sister Margaret. While the character Sister James is based on McEntee, the characters Father Flynn and Sister Aloysius, along with the story of abuse within the school where she taught, are entirely fictional and created by Shanley for dramatic purposes.
