As America began to emerge as a global superpower at the turn of the 20th century, an unlikely friendship developed between Samuel Clemens, the author better known as Mark Twain, and John Hay, Secretary of State under Presidents William McKinley and Theodore Roosevelt. In his latest book, The Statesman and the Storyteller: John Hay, Mark Twain, and the Rise of American Imperialism, author and filmmaker Mark Zwonitzer explores the correspondence between the two men, and what it reveals about America at that pivotal point in its history.
