Proof won playwright David Auburn a Pulitzer Prize and a Tony Award in 2001 for its powerful portrayal of the thin line between genius and insanity, and now Oil Lamp Theater brings it to the Glenview stage. In the play, a famous mathematician dies, leaving his troubled adult daughter Catherine, who has spent years caring for him, to deal with her own dilemmas. This moving drama explores Catherine's fear that she inherited her father's madness/genius, and her desperate attempts to stay in control -- despite the complications of a budding romance with one of her father's former students and the arrival of her long-estranged sister. The New York Daily News called the play "rich and compelling ... full of life, laughter and hope." Set in Chicago, the play chronicles the discovery of self identity through intellectual and emotional challenges and explores the power of love to help us reach our true potential.
