There were at least 19 Black scientists and technicians who worked on the Manhattan Project. In the labs, there were at least 19 Black scientists and technicians among the 400 or so scientists employed by the project. The project was unique for bringing together "colored and white, Christian and Jew" for a common cause, Arthur Compton, the Manhattan Project director in Chicago, said. The Manhattan Project did create opportunities for Black Americans' advancements, but many Black workers grappled with Jim Crow segregation. Many Black scientists involved in the Manhattan Project went on to build careers that advanced technology and expanded opportunities for other Black scientists.
