Proof-4David Auburn’s acclaimed play Proof was awarded the 2001 Pulitzer Prize and the Tony Award for Best Play when it was originally staged on Broadway.

“Highly recommended” – The Independent on Sunday (5 Stars)


Catherine has cared for her father Robert, a renowned mathematician, through his mental illness for the past five years. His ex-student, Hal, discovers a ground-breaking proof in Robert’s office but the question is posed: who is the real author of this brilliant work? Catherine struggles to solve this, and the most perplexing problem of all: how much of her father’s genius – or madness – has she inherited?
