D. G. Hart, professor of history at Hillsdale College, has taught and written about United States religious and intellectual history for more than three decades. He is the author of many books, including, most recently, American Catholic: The Politics of Faith During the Cold War; Benjamin Franklin: Cultural Protestant; Damning Words: The Life and Religious Times of H. L. Mencken; and Patriots and Protestants: Presbyterians in the Age of Revolution. Teaching jobs have taken Hart, his wife Ann, and their cats to Massachusetts, Maryland, Illinois, California, and Michigan, but Hart grew up in the suburbs of Philadelphia and has lived much of his life in the Quaker City.
