Roslyn D. Robinson worked as a driver and in the administration office for the Chicago Met Lab. Her husband, Sidney, was an engineer who worked on the Manhattan Project. In this interview, she talks about her early life, as well as her duties in Chicago and the omnipresent emphasis on secrecy. She recalls her husband’s hospitalization and quarantine after a mysterious “spill” in his laboratory at the New Chem Building. She also remembers learning about the project’s true purpose when Little Boy was dropped on Hiroshima, her reaction to that event, and how the Project continued to affect their lives after the war.
