The Metallurgical Laboratory or "Met Lab" at the University of Chicago was part of the World War II–era Manhattan Project, created by the United States to develop an atomic bomb. It was where Enrico Fermi created the first self-sustaining nuclear chain reaction under the university's football stadium.
