Proof by David Auburn

Directed by Steve Hart

The play concerns Catherine, the daughter of Robert, a recently deceased mathematical genius in his fifties and professor at the University of Chicago and her struggle with mathematical genius and mental illness. Catherine had cared for her father through a lengthy mental illness. Upon Robert's death, his ex-graduate student Hal discovers a paradigm-shifting proof and prime numbers in Robert's office. The title refers both to that proof and to the play's central question: Can Catherine prove the proof's authorship?
