Carolyn Beatrice Parker (1917–66) was a true hidden figure. Raised in a family of scientists, she earned a bachelor’s degree from Fisk University in 1937 and a master’s in mathematics from the University of Michigan in 1941. From 1943 to 1947, Parker worked on research and development for nuclear weapons as part of the Dayton Project, a division of the Manhattan Project. After World War II, she earned a master’s degree in physics from MIT and completed her coursework for her PhD. But before she could complete her doctoral program, she died at age 48 from leukemia, an occupational hazard for Dayton Project workers. Parker is the first African American woman known to have gained a postgraduate degree in physics.
