Proof

By: David Auburn

Playhouse Debut

Winner of the 2001 Pulitzer Prize and Tony Award for Best Play, this wonderfully-funny, ambitiously-constructed play is already an American classic. On the eve of her 25th birthday, Catherine has spent years caring for her brilliant yet unstable father, a famous mathematician. Now, following his death, she must deal with her own volatile emotions and the discovery of a mysterious notebook that draws her into the most difficult problem of all: How much of her father's madness - or genius - will she inherit?
