Proof won playwright David Auburn a Pulitzer Prize and a Tony Award for its powerful portrayal of the thin line between genius and insanity, and now Edmonds Driftwood brings it to the Seattle stage. In the play, a groundbreaking mathematical proof turns up in the attic of a recently-deceased math genius, leaving Catherine, his troubled daughter, to track down its origins and prove its authorship. This moving drama explores Catherine's fear of following in her father's footsteps, both mathematically and mentally and her desperate attempts to stay in control, despite a budding romance with one of her father's students and a longtime conflict with her sister. The New York Daily News called the play "rich and compelling ... full of life, laughter and hope."
