Dr. John Wigger is Professor and Chair of the Department of History at the University of Missouri. His research focuses on American religious and cultural history. What has always interested him most are religious movements that grow quickly and become large because they do something new in their cultural setting. He has written extensively on early American Methodism and is currently working on a book, under contract with Oxford University Press, on the PTL Club empire of Jim and Tammy Bakker. Professor Wigger's books include American Saint: Francis Asbury and the Methodists (Oxford University Press, 2009), Taking Heaven by Storm: Methodism and the Rise of Popular Christianity in America (Oxford, 1998; paperback, University of Illinois Press, 2001), and Methodism and the Shaping of American Culture, co-edited with Nathan Hatch (Kingswood Books, 2001). Professor Wigger earned a B.S. in Petroleum Engineering from West Virginia University and worked for Conoco for seven years before returning to grad school. He earned a PhD from the University of Notre Dame in 1994 and has been at the University of Missouri since 1996.
