More From Katherine G.

In this video

In this MAKERS interview, Katherine G. Johnson talks about her early affinity for mathematics, a college professor who noticed her gift and pushed her to pursue advanced math courses and how she eventually became a NASA mathematician who calculated, among many other computations, the trajectory for the space flight of Alan Shepard, the first American in space; John Glenn, the first American to orbit earth; and Apollo 11, the first human mission to the moon.

Katherine G.'s Biography

Love for Math:Because there's an exact answer.
Early Affinity for Numbers:"They tell me I counted everything."
Growing Up an African American Girl:"You could be a nurse or a teacher."
The Power of Teachers:"The fact that teachers can obstruct or they can assist. And mine always assisted me in moving up."

Katherine G. Johnson is a pioneer in American space history. A NASA mathematician, Johnson's computations have influenced every major space program from Mercury through the Shuttle. She even calculated the flight path for the first American mission space.
Born in 1918 in West Virginia, Johnson was a talented student who entered college at only 15 years old. At West Virginia State University, W.W. Schiefflin Clayor, the third African American to earn a PhD. in mathematics, recognized Johnson's abilities and motivated her to take advanced math. Johnson would go on to earn a graduate degree in mathematics.
In 1953, Johnson was contracted as a research mathematician at the Langley Research Center with the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA. She worked in a pool of women performing math calculations until she was temporarily assigned to help the all-male flight research team, and wound up staying there. Johnson’s specialty was calculating the trajectories for space shots which determined the timing for launches, including the Mercury mission and Apollo 11, the mission to the moon.
