Jack Lessenberry speaks with author Martin J. Sherwin, Pulitzer Prize winner for his biography, "American Prometheus, the Triumph and Tragedy of J. Robert Oppenheimer," co-authored with Kai Bird. Publisher's Weekly says of the book, "Sherwin has spent 25 years researching every facet of Oppenheimer's life, from his childhood on Manhattan's Upper West Side and his prewar years as a Berkeley physicist to his public humiliation when he was branded a security risk at the height of anticommunist hysteria in 1954." This episode of Deadline Now re-aired on November 2, 2007.
