Awards
As World War II came to a close, scientists and administrators associated with the Metallurgical Laboratory received certificates of appreciation for their service to the nation. Some like Enrico Fermi and University of Chicago President Robert Hutchins were acknowledged in formal ceremonies. Other Met Lab workers employed within the U.S. Army’s Manhattan Engineer District, the official name of the Manhattan Project, were presented a smaller but no less distinctive award: an A-Bomb pin, bronze for those serving less than a year, silver for those with more than a year’s service.
