Yentl

Yentl is a play by Leah Napolin and Isaac Bashevis Singer. Based on Singer's short story "Yentl the Yeshiva Boy," it centers on a young girl who defies tradition by discussing and debating Jewish law and theology with her rabbi father. When he dies, she cuts her hair, dresses as a man, and sets out to find a yeshiva where she can continue to study Talmud and live secretly as a male named Anshel. 

When her study partner Avigdor discovers the truth, Yentl's assertions that she is "neither one sex nor the other" and has "the soul of a man in the body of a woman" suggest the character is undergoing a gender identity crisis, especially when she opts to remain living as Anshel for the rest of her life.

As early as 1968, Barbra Streisand had expressed interest in a film adaptation of Singer's short story. Using the Napolin/Singer play as her source material, she wrote a detailed forty-two page treatment, the first to conceive of the movie version as a musical. The resulting 1983 production veered dramatically from the original short story and play by allowing Yentl to reveal her true feelings for Avigdor and having her return to her female self and sail for the United States at the end.
