On July 4, 2026, as the United States marks its 250th birthday, a library will open in the North Dakota Badlands that looks less like a civic institution than a manifesto built in stone and steel. Designed by the international architecture firm Snøhetta, the Theodore Roosevelt Presidential Library in Medora will be the nation’s only carbon-neutral presidential library—a monument to conservation, leadership, and the rugged individualism of the 26th president, rising from the very landscape that made Roosevelt who he was.
Completing it required one final gift. On Thursday, that gift arrived: $26 million from Kenneth C. Griffin, founder and CEO of the $69 billion hedge fund Citadel. The library’s west wing will bear his name.
