Katherine Johnson is now mostly known as a “Hidden Figures” mathematician whose computations made it possible to launch an American astronaut into orbit. Yet not many people know that her firstborn, Joylette Goble, was also raised in that same house full of numbers and followed a similar path, initially by way of math and NASA herself, and subsequently as the person who manages her mother’s story for the world.
Who Is Joylette Goble?
Joylette Goble, whose married name is Hylick, is the eldest daughter of Katherine Johnson. Her mother was Katherine Goble, who married James Francis Goble in 1939. The pair, who were married from 1969 to 1977, had three daughters: Joylette, Constance, and Katherine (usually called Kathy). Goble died in 1956 after an extended illness, and Katherine remarried Lieutenant Colonel James A. Johnson in 1959, integrating the Goble children into a new family structure while retaining the Goble name as a component of their identity.
Growing Up in the Goble-Johnson Household
Growing up with Katherine Johnson as a mother was to grow up with numbers, discipline, and silent ambition before the country knew her name. The family endured segregation in Virginia and West Virginia as Katherine was, at that time, traveling for work in a profession few women had access to, and even fewer Black women. That milieu helped to shape Joylette at an early age: she grew up watching her mother work every day, and came to the conclusion that math was nothing to be afraid of. That was just the family business.
Following Her Mother into Mathematics and NASA
Joylette did not only look up at her mother’s profession from afar; she pursued a career in the same field. She later became a mathematician at NASA Langley Research Center, where Katherine Johnson had spent years determining flight paths and orbital trajectories. Langley was no longer just a symbolic point of her mother’s shadow, but a place Joylette found herself actualized in her own techno-sojourner whose hands-on science unfortunately rare for women of her generation: Ladies Playing Lady Code PG-41 working science, holding the course steady, charting trajectories.
Life After NASA: Lockheed Martin and Beyond
After NASA, Joylette went into the private sector, retiring from Lockheed Martin where she worked in information technology. That change from pure math to IT is indicative of a career that spanned decades of evolution in the aerospace and tech industries, and it illustrates a woman who kept evolving rather than resting on the Johnson family name.
Telling Her Mother’s Story
After the movie “Hidden Figures” made Katherine Johnson a household name in 2016, Joylette took on a different kind of job: telling her mother’s real story, not just the one told in the movie. Together with her sister Katherine Moore, she took on the task of writing projects that would help to keep their mother’s voice alive.
One Step Further
Joylette and Katherine Moore collaborated with their mother in 2021 on the National Geographic Kids picture book “One Step Further: My Story of Math, the Moon, and a Lifelong Mission.” The book is written in Johnson’s own voice, but it incorporates her daughters’ memories and perspectives throughout, providing a family-oriented view of NASA history for children, rather than just a textbook account.
My Remarkable Journey
The sisters also contributed that year to “My Remarkable Journey: A Memoir,” a full-length memoir for adults published by Amistad, an imprint of HarperCollins. Co-author with Lisa Frazier Page, the book delves further into Katherine Johnson’s life, including her childhood in West Virginia, her work at NASA, and the deeply held beliefs that guided her throughout. Joylette’s participation meant the memoir was not secondhand reconstruction; it is spoken from someone who shared the life of the woman.
Honoring Katherine Johnson’s Legacy
Joylette has gone on to represent her mother’s legacy long after the publication of the memoir. In 2025, Moore and her sister, Katherine Moore, returned to Bluefield, Virginia, seven decades after the family had lived there, to participate in the unveiling of historical plaques commemorating Katherine Johnson’s early teaching career and the house where she raised her daughters. During a panel discussion, Joylette also spoke about how being honored is a way for her mother to live on in multiple generations, saying that children, teachers, and adults continue to be inspired by her story.
What Joylette Goble’s Story Tells Us
The life of Joylette Goble is not nearly as well known as her mother’s, and that is clearly by design rather than accident. Goble developed her own technical career rather than relying on her family name, and then came out of the shadows only when she felt she needed to safeguard her mother’s history from the world. This combination of silent competence and careful stewardship is itself a legacy, even if it is one that rarely makes the headlines.
