America's entrance into the Atomic Age, Los Alamos was a small ranching community and the site of an exclusive boys' school until 1943. As the Manhattan Project unfolded, Pvt. J.J. Michnovicz--first assigned to Los Alamos as a photographer by the military but later working as a civilian--recorded the everyday spirit of the people and the events that shaped this mountain town into a home . . . and secret scientific hotbed. This comprehensive view of the social and professional world of Los Alamos is the photographic journal of a singular period, as seen through the eyes of one soldier.
