On the theory that every grandmom gets to brag at least once a year about one of her grandkids, I’m claiming that right to tell the world that my granddaughter Amy is one of the leads in an off-Broadway play. She has the role of Emilie in EMILIE’S VOLTAIRE at the Samuel Beckett Theater in Manhattan. So if you’re a New Yorker and like theater, go see this play set during the French Enlightenment. It “chronicles the volcanic, law-breaking, sexually-driven, intellectually-fuelled, sixteen-year love affair” between Voltaire and Emilie, the most beautiful woman in Europe. The play runs through Feb. 7. Tickets are available through TicketCentral.
