David Auburn’s award winning play follows Catherine, a young woman who turned the focus of her life to caring for her brilliant, but mentally deteriorating, father until his death. When one of her father’s ex-students finds a groundbreaking mathematical proof he believes it to be the work of the deceased professor, when in fact it was discovered by Catherine. No one believes that the calculations are hers and now she must prove her honesty. The play deals with family conflict, the mysterious nature of genius and insanity, and the struggle to prove one’s own worth. Proof originally opened off-Broadway at the Manhattan Theatre Club in 2000 and won the Lucille Lortel Award for best off-Broadway drama. It moved to Broadway in 2001 and won the Pulitzer Prize, the Tony Award, the New York Critics’ Circle Award and the Drama Desk Award for Drama. $25 for General Admission; $20 for Seniors (+65), SATCO, ATAC, MIL w/ID; $10 for Full time students with ID.
