History That Shaped a Nation The history of Dubuque is as important to the nation as it is Iowa. Look into the life of railroad-attorney Abraham Lincoln as he pays a visit to a prominent railroad engineer in Dubuque prior to becoming president. Follow congressional debate on whether U.S. Rep. William Vandever (R-IA) had the right to simultaneously hold a seat in Congress and a commission in the U.S. military during the Civil War. View some of the more popular Americans photographed by famed Dubuque photographer Samuel Root, including an image of Frederick Douglass captured while in Dubuque for one of three lectures the "Self-made Man" made in the Key City. Author and historian John T. Pregler sheds light on these rediscovered facets of American history and many others.
