On todays Modern Notion Daily podcast, were talking spies and subways cars in the ocean. First were in the studio with Alex Kershaw, author of Avenue of Spies: A True Story of Terror, Espionage, and One American Familys Heroic Resistance in Nazi-Occupied Paris (Crown, August 2015). Kershaw tells the story of an American doctor and Swiss nurse who became part of the French Resistance in Nazi-occupied Paris. Later in the show, we welcome Jeff Tinsman, the artificial reef project manager for the Delaware Division of Fish and Wildlife, as well as Stephen Mallon, an industrial photographer. Mallon photographed New York City subway cars as they were dropped into the Atlantic Ocean to become structures in the artificial reef program that Tinsman leads.
