Early years

In 1953, Robert Krohn, who was in charge of early nuclear tests at what was then called Los Alamos Scientific Laboratory, decided the Laboratory needed a museum to house historical weapons-research artifacts. Krohn convinced

Norris Bradbury Norris Edwin Bradbury (May 30, 1909 – August 20, 1997), was an American physicist who served as director of the Los Alamos National Laboratory for 25 years from 1945 to 1970. He succeeded Robert Oppenheimer, who personally chose Bradbury ...

became the first Laboratory museum. Already fitted with a vault door, the ice house satisfied security standards for housing the classified exhibits Krohn wanted to preserve. The ice house Museum opened to official visitors in 1954. In 1963, Robert Porton, director of community relations at the Laboratory, expressed an interest in adding unclassified exhibits to the Museum. Bradbury approved the transfer of unclassified exhibits to an area open to the public, and soon World War II-era documents and photographs, tracing the development of the town and the Laboratory, were displayed with scientific memorabilia and working models of unclassified research projects. In its first year, 14,000 visitors from 50 states and 40 countries visited the Museum. In 1965, the Museum was moved to larger quarters. The range and number of exhibits grew rapidly and included many hands-on models contributed by scientific groups and divisions within the Laboratory.

Named after Norris E. Bradbury

In 1970, the museum was renamed the Norris E. Bradbury Science Museum, honoring the laboratory's second director. Eventually, the museum's official name was shortened to the Bradbury Science Museum. Major renovations to the Museum took place in 1981. Informal, donated exhibits gave way to professionally designed exhibits in a formal museum atmosphere. Videotapes, videodisks, and interactive computer programs were introduced. New artifacts included a Mark 12A warhead, models of Vela and Navistar verification and communication satellites, and an air-launched cruise missile.

Moved to downtown Los Alamos

By 1987, annual attendance had reached 80,000, and parking space for visitors was disappearing. Laboratory officials began exploring options for relocating the Museum site. In April 1993, the Museum moved into its new and present location in the heart of downtown Los Alamos. The building was designed by William Agnew and Associates and is leased by the Laboratory from a private owner.

Approximately 40 interactive exhibits trace the history of the World War II
