Step-by-step explanation:
NASA research mathematician Katherine Johnson is photographed at her desk at Langley Research Center in 1966. Johnson began her career in 1953 at the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, one of a number of African-American women hired to work as "computers" in what was then their Guidance and Navigation Department, just as the NACA was beginning its work on space. Johnson became known for her training in geometry, her leadership, and her inquisitive nature; she was the only woman at the time to be pulled from the computing pool to work with engineers on other programs.
