Surrounded by a fence patrolled by armed guards, the inhabitants of Oak Ridge--most of whom were unaware of the nature of the activity at the facility--spent much of the war period physically cut off from the outside world. The authors analyze the people who lived and worked in this unique setting. They use previously classified material and extensive oral interviews to portray the stresses and patterns of life in the city, focusing on problems of housing, racial segregation, education, recreation, interaction with surrounding communities, the extreme security measures, and the eventual "normalization" of the community. The history of war-time Oak Ridge graphically reveal the impact of the single-minded, massive endeavor on the lives of those who struggled, mostly unknowingly, to launch the nation and the world into the Atomic Age.
