Katherine Johnson's Children Explained: Names, Biographies, and Family Heritage
Following Katherine Johnson’s death on February 24, 2020, at the age of 101, Joylette and Kathy became the primary curators of their mother's historical papers, personal artifacts, and public memory. They have collaborated directly with NASA, the Smithsonian National Air and Space Museum, and universities nationwide to ensure the historical record remains accurate.
In 2021, the sisters published One Step Further, an illustrated biography geared toward young learners. The book corrects widespread pop-culture myths, clarifying that while Hollywood dramatized Katherine walking miles across Langley to use a segregated restroom, the true, daily struggle was far quieter: managing intense calculations under tight deadlines, fighting for inclusion in morning briefings, and rushing home to oversee homework for three growing daughters.
Through their foundation appearances and classroom outreach, Joylette and Kathy emphasize that their mother's greatest achievement was not merely calculating orbital trajectories for the moon landing, but proving that Black women belonged at the center of institutional science.
