Katherine Johnson (1918-2020) was an American mathematician whose calculations of orbital mechanics were critical to the success of the first U.S. crewed spaceflights. Working at NASA and its predecessor NACA, she calculated trajectories for the Mercury and Apollo programs and was recognized with the Presidential Medal of Freedom in 2015.

What Did Katherine Johnson Calculate?

Johnson's most famous contribution was verifying the orbital equations for John Glenn's Friendship 7 mission in 1962, the first American orbital spaceflight. Glenn personally requested that Johnson check the electronic computer's calculations before he would fly. She also calculated the trajectory for the Apollo 11 mission to the Moon and worked on the Space Shuttle program.

What Barriers Did Katherine Johnson Face?

As a Black woman working at a segregated NASA facility in Hampton, Virginia, Johnson initially had to use separate bathrooms, dining facilities, and office spaces. She overcame these barriers through exceptional mathematical talent and quiet determination, gradually earning the respect of engineers who relied on her calculations for mission-critical decisions.

How Was Katherine Johnson's Story Brought to Public Attention?

Marguerite Lee Shetterly's 2016 book Hidden Figures and the subsequent film brought Johnson and her colleagues Dorothy Vaughan and Mary Jackson to worldwide attention. The story revealed how Black women mathematicians contributed essential work to the space program while facing racial and gender discrimination.

What Is Katherine Johnson's Legacy?

Johnson received the Presidential Medal of Freedom from Barack Obama in 2015 and had a NASA facility named in her honor. Her story inspired a generation of women and people of color to pursue careers in STEM. She demonstrated that mathematical genius knows no color or gender.
