History

The Department of Energy (DOE) has one of the richest and most diverse histories in the Federal Government. Although only in existence for a quarter century, the Department traces its lineage to the Manhattan Project and beyond.

Researchers interested in documenting DOE history are welcome to browse DOE records, including declassified materials on the nuclear weapons program.
 
DOE supports museums and historic facilities across the country dedicated to displaying and interpreting the history of the Department and its scientific and technological missions. Public tours are also available at some of the Department's sites.

Owning some of the twentieth century's most historically significant physical properties, the Department oversees a vigorous historic preservation program dedicated to preserving and interpreting its heritage.
