Proof

Poignant and surprisingly funny,  a Pulitzer Prize- and Tony Award-winning family drama that explores the relationship between brilliance and madness. It centers on Catherine, a young woman who has spent years caring for her father, a once-in-a-generation mathematician now stricken with mental illness. The play opens on the eve of his funeral, as Catherine struggles with issues of responsibility, trust, and the possible inheritance of both her father’s brilliance and madness, while dealing with her sister Claire’s well-intentioned intrusions and her own budding relationship with Hal, one of her father’s former doctoral students - forcing her to confront what she truly believes about herself.
