“‘In the Shadow of Genius: The Brooklyn Bridge and Its Creators” is the latest book by photographer and author Barbara Mensch. In it, Mensch combines her striking photographs with a powerful first-person narrative. She takes the reader on a unique journey from recalling her experiences living alongside the Brooklyn Bridge and then traces her quest to understand the brilliant minds and remarkable lives of those who built it: John, Washington and Emily Roebling. In this installment of “Leonard Lopate at Large” on WBAI, Leonard and Barbara discuss this iconic piece of the New York City skyline.
