At a moment of global crisis, in a windowless squash court below the football stadium bleachers at the University of Chicago, a group of scientists changed the world forever.

On December 2, 1942, a team of researchers led by Enrico Fermi, an Italian refugee, successfully achieved the world’s first human-­created, self-­sustaining nuclear chain reaction. Racing to beat Nazi Germany to the creation of an atomic weapon, the team of researchers, working as part of the Manhattan Project, split uranium atoms contained within a large graphite pile—Chicago Pile-­1, the first nuclear reactor ever built.
