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.

The Manhattan Project at Hanford and the Tri-Cities looked like many areas of the American South during the 1940s. Practices of segregation, discrimination, and racism were embedded into the fabric of workplace and community. Latinos/as who were recruited to Hanford for the Manhattan Project experienced prejudice and segregation. Their presence in the workforce and community demonstrates how race, ethnicity, and gender impact demographics across the Tri-Cities then and now.

Los Alamos National Laboratory was created to develop the atomic bomb. The government decided on Los Alamos County in New Mexico as a site for the Manhattan Project. Most of the land already belonged to the government as part of the Forest Service, but there was a community of Hispanic homesteaders and other property owners in the area. The homesteaders received less than their Anglo counterparts for their land. In 2005, they received reparations for the unfair treatment.
