Proof

A mathematical proof found in the attic

After the death of her mathematical genius father, Catherine, who gave up her own study of mathematics to tend to him, claims that she is the author of a mathematical proof found in the attic among his unpublished, mostly incoherent notebooks by Hal, one of his former students. But what "proof" does Catherine have that she, and not her father, is the author? Her older sister, home to attend the funeral, doubts her claim and, in fact, doubts Catherine's own sanity. Hal, who has professional ambitions of his own, isn't exactly disinterested and may not be trustworthy; his sleeping with Catherine has also complicated the issue.

Professional ambitions of his own

Her older sister, home to attend the funeral, doubts her claim and, in fact, doubts Catherine's own sanity. Hal, who has professional ambitions of his own, isn't exactly disinterested and may not be trustworthy; his sleeping with Catherine has also complicated the issue. The elusiveness of genius in general and the difficulty of a mathematical proof in particular here become metaphors for the uncertainties of love, trust, and personal integrity.

This wonderful play has already won the Kesselring Prize for Auburn, also a recipient of a Guggenheim Fellowship. Proof's deft dialog, its careful structure, and the humanity of the central characters are themselves proof of a major new talent in the American theater.
