Dan Howe grew up in Denver and now lives in Los Angeles. He learned to love history when he was about 6 years old; his father put him on his lap and told him about Hannibal crossing the Alps with elephants to fight the Romans. He has taught at Yale, UCLA, and Oxford. He won the Pulitzer Prize for What Hath God Wrought: The Transformation of America, 1815-1848 (2007) and has been elected to the American Academy of Arts and Sciences. He is also author of Making the American Self: Jonathan Edwards to Abraham Lincoln (1997), and he intends his next book to be about the U.S.-Mexican War.
