This commemorative pin was developed by the Office of Health, Safety and Security, U.S. Department of Energy, to honor the courageous efforts of the thousands of men and women who supported our nuclear efforts during World War II and the Cold War.

Shown in its center is a replica of the lapel pin issued in 1945 by the Secretary of War to approximately 132,000 Manhattan Project workers, which is symbolic of the beginning of the Atomic Age. The Manhattan Project led to the development of the atomic bomb by the United States that ended World War II and paved the way in preserving the national security of this Nation and the security of our friends and allies for decades.

On May 22, 2009, the United States Senate unanimously approved Senate Resolution 151 designating October 30, 2009, a National Day of Remembrance in honor of the thousands of men and women who supported our nuclear efforts during the Cold War.

As members of the Department of Energy community, we are fully aware of the significant responsibilities we face in meeting today's challenges. The pin is a reminder for all of us to carry on the tremendous legacy of the World War II and Cold War workers who put their health and lives in harm’s way in the service of their country.
