Barnard lecturer Liza Gennaro and actress Sarah Jessica Parker have something in common. Besides being cultured New Yorkers, they both played important parts in crafting the 1996 Broadway revival of Once Upon a Mattress, a musical based upon the fairytale The Princess and the Pea. Sarah Jessica Parker played the lead role while Gennaro choreographed the show. Gennaro says she loves that she is “always challenged” by her teaching, writing, and choreography projects.
