The rich history of the Manhattan Project could not have succeeded without the hundreds of workers from Hispanic backgrounds, especially in the surrounding communities neighboring Los Alamos. At the Los Alamos laboratory, locals worked as machinists, technicians, facilities workers, and other critical positions. Hispanics built the town—constructing roads, town buildings, and residences. They also supported the community as dorm matrons, housekeepers, childminders, gardeners, cooks and wait staff in the dining halls, and in many additional jobs needed to keep the community functioning. There were also a limited number of Hispanic scientists and technicians who worked for the Manhattan Project.  

Today, it is a challenge to find Hispanic histories among the official records. Many published works mention “locals,” briefly mentioning their contributions to the project, sometimes confusing the local Pueblos and local Hispanics. However, a few Hispanic stories have been recognized and published. Learn more about the Hispanic connections to the Manhattan Project below.
