Proof
David Auburn’s Proof concerns math and mathematicians, but is better described as a play about the complexities of passion and unfathomable intelligence. Here, math may stand in for any pursuit that's demanding and precise and beautifully rewarding for those who pursue it enough. The play is also, in no small part, about human interaction, obligation, ownership, and mental illness. Director Suzi Regan helms a production well worthy of this dense, masterfully efficient script in a hard-hitting two hours at Tipping Point Theatre.
Fittingly, the story begins with guarded Catherine (Kate Peckham) and her father, storied math legend and University of Chicago professor Robert (Hugh Maguire), gingerly talking about the trappings of sanity. The conversation heaps on layers of context when the characters quickly reveal that Robert has recently died, having grappled with career-ending insanity for years under Catherine’s watchful care; the questions this interaction raises about her own mental state are not lost on either of them. Also within Catherine’s orbit are the alive and present Hal (Chris Korte), a young member of the math faculty warily permitted to scour Robert’s notebooks, and Claire (Kelly Komlen), her take-charge, put-together sister who swoops in from New York to remove Catherine from the dilapidated house of their childhood. The first act progresses in a linear fashion, before and then after the funeral, exposition spread thick in this slice-of-life approach that begins to twine the three living characters’ lives together. It’s all building toward a reveal changes the game entirely with one jaw-dropping utterance.
