Robert S. Norris is a senior fellow at the Federation of American Scientists and author of the definitive biography of General Leslie R. Groves, "Racing for the Bomb: General Leslie R. Groves, the Manhattan Project's Indispensable Man." In this interview, Norris provides an overview of how the Manhattan Project began, how the project sites were selected, and the role of British scientists in the project.
