Civil War Era Studies Professor Allen Guelzo was mentioned in a November 26 Chronicle of Higher Education article about the recent Lincoln film.
From the Chronicle:
Doris Kearns Goodwin's 2005 Team of Rivals: The Political Genius of Abraham Lincoln (the basis for Spielberg's film) highlighted Lincoln's leadership and skill at bringing his competitors into his cabinet. James M. McPherson's Tried by War: Abraham Lincoln as Commander in Chief (2008) offered new insights into the president's development as a shrewd military man. Harold Holzer co-chaired the Abraham Lincoln Bicentennial Commission and brought out a steady stream of books, including Lincoln President-Elect: The Great Secession Winter 1860-1861 (2008), which illuminated Lincoln's political craftiness. Allen C. Guelzo also produced numerous books, including Lincoln's Emancipation Proclamation: The End of Slavery in America (2004) and Lincoln: A Very Short Introduction (2009), which reemphasized Lincoln's antislavery credentials. Eric Foner's The Fiery Trial: Abraham Lincoln and American Slavery (which won the 2011 Pulitzer Prize for History) explored how Lincoln's views of slavery changed—and steadily grew closer to that of the Radicals. All helped restore Lincoln to a position of prominence.
