John Prevas is a New York Times bestselling author whose first book, Hannibal Crosses the Alps, ignited the debate among academics over which pass Hannibal used -- a debate which continues today. He has been featured in a documentary about Hannibal filmed in the Alps by the BBC and has spoken on Hannibal as a leadership figure to United Nations ambassadors, the Smithsonian Institute, the Hoover Institute at Stanford University, the National Archaeological Museum in Athens, and at Forbes CEO conferences. Prevas has appeared on the History Channel, CNN, CNN International, NPR, C-Span's Book TV, and Fox Television.
