PROOF

BY DAVID AUBURN
DIRECTED BY SOPHIA WATT
BEGINS SEPTEMBER 11, 2026

Winner of the Pulitzer Prize for Drama & Tony Award for Best Play

In a Chicago home, Catherine is grieving for her father, a celebrated mathematician whose brilliance has been overtaken by mental illness. As one of his students searches through a mountain of notebooks for one last breakthrough, Catherine’s sister Claire arrives with plans for a future Catherine isn’t sure she wants.

Then a startling discovery turns grief into a battle over who to trust and what to believe. Winner of the Pulitzer Prize and Tony Award for Best Play, PROOF is an emotionally charged drama about family, legacy, and the frightening question of what we inherit.

“Exhilarating...has the pace of a pyschological thriller.”
– The New York Times
