Jun 17, 2019 - We welcome a familiar passenger back our time machine. It's Dr. Paul Kahan, who we last chatted with about his book Amiable Scoundrel: Simon Cameron, Lincoln's Scandalous Secretary of War. Prior to that, he entertained and enlightened us with The Bank War: Andrew Jackson, Nicholas Biddle, and the Fight for American Finance. We put together a video trailer for that book, to share some of the illustrations and political cartoons of the time. Dr. Kahan holds a Ph.D. in U.S. history from Temple University, an M.A. in Modern American History & Literature, and B.A.s in history and English. He’s also the author of two books on Philadelphia’s Eastern State Penitentiary, as well as The Homestead Strike: Labor, Violence, and American History Critical Moments in American Industry .
