Katherine Johnson
Katherine Johnson was a black female mathematician who worked on the trajectory analysis for America’s first human spaceflight.
She worked at the all-black West Area Computing section at the National Advisory Committee for Aeronautics’ (NACA’s) Langley laboratory and because of her brilliant mathematical mind, in just two weeks, was moved into a new department in the Flight Research Division.
In 1962 NASA was preparing for the orbital mission of John Glenn. New computers had been programmed with equations that would control the trajectory of the capsule in Glenn’s Friendship 7 mission, but Glenn was wary of trusting them as they were prone to blackouts.
