Manhattan Project: Los Alamos
built 178 days ago
Protecting the secrecy of the Manhattan Project was one of the most complex intelligence and security operations during the war. At the Los Alamos facility, all residents were confined to the project area and surrounding town. Though several leading scientists knew the nature and scope of the entire project, most lab facilities were compartmentalized with various teams working on different project elements. Those who worked in the lab were forbidden to discuss any aspect of the project with friends or relatives. Military security personnel guarded the grounds and monitored communications between research teams. Official communications outside of Los Alamos, especially to the other Manhattan Project sites, were coded and enciphered.

[P]reservationists have gone behind the security fences to preserve for the first time a structure in which the Manhattan Project scientists did their work at Los Alamos National Laboratory. They contend the building is as significant as George Washington's home or a Civil War battlefield.

Jay Weschler tested explosives for the Manhattan project in Los Alamos. At first, even he wasn't sure what he was working on. He recollects, "Then it became a little more apparent what some of the equipment was that we were collecting and building."
