PROOF by David Auburn - Winner of the Pulitzer Prize. New Extended Run

On the eve of her twenty-fifth birthday, Catherine, a troubled young woman, has spent years caring for her brilliant but unstable father, a famous mathematician. Now, following his death, 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 the 103 notebooks that her father left behind. 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 will she inherit?

"PROOF surprises us with its aliveness…Mr. Auburn takes pleasure in knowledge…At the same time, he is unshowily fresh and humane, and he has written a lovely play.“ - NY Observer

"A wonderfully funny…ambitiously constructed work…" — Variety.
