On Sunday, my friend Gordon Wood was struck and killed in a car accident. Gordon taught history at Brown Univ. and was among the most accomplished historians America has produced. He won the 1993 Pulitzer Prize for The Radicalism of the American Revolution, and his earlier book The Creation of the American Republic, 1776–1787 took the 1970 Bancroft Prize. He also received the National Humanities Medal. He was, in my view, the finest historian of America's founding—which makes it all the sadder that he did not live to see the nation's 250th birthday. His reputation reached popular culture, too. Matt Damon's character in Good Will Hunting invokes him by name in the famous bar scene, accusing a Harvard student of simply "regurgitating Gordon Wood, talking about [...] the pre-Revolutionary utopia and the capital-forming effects of military mobilization." I feel fortunate to have collaborated with Gordon on several projects. In a 2019 anthology I compiled, he wrote an essay on the possibility of a shared American narrative. He centered his argument on equal rights as "the most radical and most powerful ideological force" the Revolution unleashed. "This powerful sense of equality is still alive and well in America," he wrote, "and despite all of its disturbing and unsettling consequences, it is what makes us one people." When I needed jacket blurbs for my new book Lincoln's Compass, coming out this November, I turned to Gordon. The fit was natural: the book argues that Abraham Lincoln took the Declaration's claim that "all men are created equal" as his guiding moral compass—and that he refocused the nation on that claim. Gordon, ever the gentleman, offered generous praise. He was, in many respects, the dean of American historians. He will be very hard to replace.
