Katherine Johnson’s birthday and the mathematics behind a journey

Born on 26 August 1918, Katherine Johnson calculated flight paths that helped carry US space missions safely from launch to return.

Katherine Coleman Goble Johnson was born in White Sulphur Springs, West Virginia, on 26 August 1918. Her mathematics supported some of the most closely watched journeys in spaceflight, from early crewed missions to work connected with Apollo.

Accuracy carried real responsibility

Johnson calculated trajectories, launch windows and emergency return paths. Before John Glenn’s 1962 orbital flight, he asked for Johnson to verify the electronic computer’s figures by hand. NASA’s biography also records her work on Apollo, the Space Shuttle and Earth resources satellites.

Talent met institutional barriers

Johnson built her career while racial segregation and sex discrimination constrained opportunities for Black women. Her story includes individual skill and the broader work of colleagues who challenged exclusion. Progress came through people changing institutions as well as excelling inside them.
