Katherine Johnson Dies at 101; Mathematician Broke Barriers at NASA
①They asked Katherine Johnson for the moon, and she gave it to them*. ②Wielding little more than a pencil, a slide rule and one of the finest mathematical minds in the country, Mrs. Johnson, who died at 101 on Monday, calculated the precise trajectories that would let Apollo 11 land on the moon in 1969 and, after Neil Armstrong’s history-making moonwalk, let it return to Earth.
③Yet throughout Mrs. Johnson’s 33 years in NASA and for decades afterward, almost no one knew her name.
④Mrs. Johnson was one of several hundred rigorously educated, supremely capable yet largely unheralded women who, well before the modern feminist movement, worked as NASA mathematicians. But it was not only her sex that kept her long marginalized and long unsung.
⑤For some years at midcentury, the black women who worked as “computers” were subjected to a double segregation: They were kept separate from the much larger group of white women who in turn were segregated from the agency’s male mathematicians and engineers.
⑥In old age, Mrs. Johnson became the most celebrated of the small cadre of black women who at midcentury served as mathematicians for the space agency. Their story was told in the 2016 Hollywood film Hidden Figures, which was nominated for three Oscars, including best picture.
