As a literature professor, Daniel Mendelsohn teaches the classics. And when his father, Jay, signed up for a class, it provided an opportunity for Daniel to get to know his dad through the works they would explore together. Daniel Mendelsohn joins us to talk about how books can teach us about those closest to us, which he writes about in his new memoir, “An Odyssey: A Father, a Son and an Epic” (Knopf). He speaks tonight at DMA Arts and Letters Live.
