Graphic design by Jennifer Tate

Winner of both the 2001 Pulitzer Prize and the Tony award for best play. Intellectual but not highbrow, funny but not lowbrow, and never sentimental or melodramatic, it strikes a beautiful balance in that it simultaneously entertains and engages the mind. On the eve of her 25th birthday, Catherine, a troubled young woman, has spent years caring for her brilliant but unstable father, a famous mathematician. Now she must deal with her own volatile emotions; the arrival of her estranged sister, Claire; and the attentions of Hal, a former student of her father’s who hopes to find valuable work in her father's notebooks. Over the long weekend that follows, a burgeoning romance and the discovery of a mysterious notebook draw Catherine into the most difficult problem of all: How much of her father’s madness – or genius – has she inherited? Please note: "Proof" contains strong language.
