Up there with the geniuses of math and science, Katherine Johnson lived to be 102, and died recently in 2020. Where did she work starting in 1953 until her retirement in 1986?

For her work at NASA, President Obama presented her with the Presidential Medal of Freedom in late 2015. He said of her: "Katherine G. Johnson refused to be limited by society's expectations of her gender and race while expanding the boundaries of humanity's reach."
