Jan Karski was a Polish resistance fighter whose reports of the horrors in Warsaw during World War II were tragically dismissed by Allied forces, an experience that haunted him for the rest of his life. Karski's story is told in the one-man play, "Remember This: The Lesson of Jan Karski," starring actor David Strathairn and directed and co-written by Derek Goldman, chair of Georgetown University’s Department of Performing Arts. Strathairn and Goldman join us to discuss the show, whose New York premiere runs through October 9.
