Bill Yenne is the author of more than three dozen books on military, aviation, and historical topics, including Operation Long Jump (2015) and Alexander the Great (2010). WWII History Magazine wrote that his book B-17 at War (2006) “is a source of unending pleasure to the Flying Fortress fan,” and Air Force Magazine noted that his primer on strategic air power “deserves a place on any airman’s bookshelf.” He has contributed to encyclopedias of both world wars, and has appeared in documentaries airing on the History Channel, the National Geographic Channel, the Smithsonian Channel and ARD German Television. A graduate of the University of Montana and the Stanford University Professional Publishing Course, Yenne is also the founder of American Graphic Systems.
