After earning a bachelor’s degree in history at University of Michigan and a doctorate in the same field from U.C. Berkeley, Thomas Leonard taught American history at Columbia University before joining the faculty at the School of Journalism. Author of “Above the Battle: War-Making in America from Appomattox to Versailles,” “The Power of the Press: The Birth of American Political Reporting,” and “News for All,” Professor Leonard focuses much of his research and teaching on the role of the press in society. He is working on a book about “notorious Americans” and how journalists and historians have helped to build them up and tear them down.
