Moshe Rynecki was a Polish-Jewish artist with hundreds of paintings to his name before he was ushered off to the ghetto during World War II. Decades later, his great-granddaughter went on a quest to find these missing family treasures. Elizabeth Rynecki joins us to talk about the difficult task of rebuilding the collection, which she writes about in “Chasing Portraits: A Great-Granddaughter’s Quest for Her Lost Art Legacy” (New American Library). She’s in town to speak tonight at 7 at the Aaron Family Jewish Community Center.
