The Department of Energy has one of the richest and most diverse histories in the Federal Government. Although only in existence since 1977, the Department traces its lineage to the Manhattan Project effort to develop the atomic bomb during World War II and to the various energy-related programs that previously had been dispersed throughout various Federal agencies.
The Department has made available to researchers and the general public a rich variety of materials and information:
- Historical Resources, including published and online histories of the Department and its predecessor agencies and information on records, exhibits, museums, and tours available online and at various locations both within and outside the Department
- A detailed timeline of the Department and its predecessor agencies that includes links to reports, speeches, press releases, and other documentation
- All things Manhattan Project, including histories, websites, a listing of the Manhattan Project Signature Facilities, and background on the proposed Manhattan Project National Historical Park.
Questions about the history of the Department of Energy or one of its predecessor agencies should be directed to the Office of History and Heritage Resources at HistoryDivision@hq.doe.gov..
