Mathematician. Leader. Heroine. Remembering Hidden Figure Katherine Johnson

Tonight, count the stars and remember a trailblazer. 

We're saddened by the passing of celebrated #HiddenFigures mathematician Katherine Johnson. She passed away at 101 years old. 

An America hero, Johnson's legacy of excellence broke down racial and social barriers while helping get our space agency off the ground.

Once a "human computer", she famously calculated the flight trajectory for Alan Shepard, the first American in space.

And when we began to use electronic computers for calculations, astronaut John Glenn said that he’d trust the computers only after Johnson personally checked the math.

As a girl, Katherine Johnson counted everything. As a mathematician, her calculations proved critical to our early successes in space travel.

With slide rules and pencils, Katherine Johnson’s brilliant mind helped launch our nation into space. No longer a Hidden Figure, her bravery and commitment to excellence leaves an eternal legacy for us all.

"We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering and technology. And there will always, always be mathematics." - Katherine Johnson 1918 -2020 

May she rest in peace, and may her powerful legacy inspire generations to come! What does Katherine Johnson’s legacy mean to you? Share in the comments.

Presented to Congress an amendment that allowed women to vote. The 19th amendment, nicknamed the “Susan B. Anthony Amendment” was passed in 1920, allowing women the right to vote.

At Langley, Admiration and Gratitude Multiply on Katherine Johnson’s 100th Birthday

When Jasmine Byrd started her job at NASA about two years ago, she knew nothing about Katherine Johnson, the mathematician and “human computer” whose achievements helped inspire the book and movie “Hidden Figures.”

At that point, the release of the film was still months away. But excitement was building — particularly at Byrd’s new workplace. She’d arrived at NASA’s Langley Research Center in Hampton, Virginia, where Johnson spent her entire, 33-year NACA and NASA career.

Soon, Byrd felt a strong connection to a woman she’d never met, nearly 70 years her senior.

“I was just enthralled with her story,” said Byrd, a project coordinator for NASA’s Convergent Aeronautics Solutions Project. Today, she works inside Langley’s Building 1244, the same hangar-side location where Johnson crunched numbers for the Flight Research Division in the 1950s.

“I am thankful for the bridge that Katherine built for someone like myself to easily walk across,” Byrd said. “It helps me to not take this opportunity for granted. I know there were people before me who put in a lot of work and went through a lot of turmoil at times to make sure it was easier for people like myself.”

Fountain of gratitude

As Katherine G. Johnson’s 100th birthday — Aug. 26 — approached, many Langley employees expressed admiration for the woman whose math powered some of America’s first triumphs in human space exploration.

Johnson did trajectory analysis for Alan Shepard’s May 1961 mission Freedom 7, America’s first human spaceflight. At a time when digital computers were relatively new and untested, she famously checked the computer’s math for John Glenn’s historic first orbital spaceflight by an American in February of 1962.

Those are just two bullet points in a brilliant career that stretched from 1953 to 1986.

Her 100th birthday was recognized throughout NASA and around the world. But at Langley, the milestone created an extra measure of pride and joy.

Graduate research assistant Cecilia Stoner, stopped on her way to Langley’s cafeteria, said she admires how Johnson remained humble — even when showered with accolades ranging from the Presidential Medal of Freedom to toys made in her likeness.

Stoner’s lunch companion, Erin Krist, chimed in. “It’s incredible what she managed to do,” said Krist, a summer intern. “She paved the way for women. We couldn’t work here today if that hadn’t happened.”

Langley’s acting chief technologist, Julie Williams-Byrd, echoed that thought.

“She opened the doors for the rest of us,” Williams-Byrd said. “Between her and Dorothy Vaughan and Mary Jackson and all the women who were at Langley at the time. It didn’t matter if they were called computers in skirts. They were here to do a job.

“It’s typical NASA culture, right?” Williams-Byrd said. “We have a mission. Everybody’s going to jump in and do what they can to make that mission successful.”

She also admires Johnson’s devotion to promoting science, technology, engineering and math studies among young people.

“While she was very focused on the technical work and really did great things there, her balance of life and responsibilities to those who would come up behind her, that really resonates with me,” Williams-Byrd said.

A modest mentor

Remarkably, a handful of current Langley employees worked side by side with Johnson. Among them is research mathematician Daniel Giesy, who started at the center in 1977.

“On my first job here, I was teamed with Katherine Johnson,” Giesy said. “She mentored me.”

Johnson showed Giesy the ropes as he and Johnson both provided mathematical and computer programming support for researchers working to find new tools for designing aircraft control systems. They eventually coauthored papers including “Application of Multiobjective Optimization in Aircraft Control Systems Design” from 1979, written with Dan Tabak.

“I would describe her as a good colleague, competent, courteous,” Giesy said. “She had her moments. If you slopped coffee on the way back from the break room, you bloody well better clean up after yourself. You don’t leave it for the janitor staff to work on.

“But she was focused on getting the job done,” Giesy said. “At that point in time, she wasn’t resting on laurels.” Only later would Giesy learn of her historic contributions to early space missions. “She did not brag on herself particularly.”

Regina Johns, who today recruits participants for tests related to crew systems, aviation operations and acoustics, arrived at Langley in 1968 as a high school intern. She returned as a contract employee in 1973 and has worked at Langley ever since.

In those early days, she remembers running into Johnson on campus occasionally. Johnson would often stop and talk, asking about her plans and what she was working on. Johns would eventually get to know Mary Jackson, another Langley researcher central to the “Hidden Figures” story.

“There weren’t a lot of minorities here at that time,” Johns said. “To know that they were engineers and mathematicians, it just gave me hope that, if they can do it, it can be done. If you work hard, you can do it.”

She, like many across the agency, said she’d like to send Johnson a birthday message.

“If I had a chance, I would say, thank you for setting the pathway for young people. Thank you for showing us that we can do anything.”

Enduring legacy

In terms of lives touched, Johnson’s work with youth stands alongside her impact as a world-class mathematician. Langley’s Katherine G. Johnson Computational Research Facility, which opened in September 2017, offers a physical reminder of her contributions.

“The Katherine Johnson building is near where I work, so I think about her often,” said Kimberly Bloom, director of Langley’s Child Development Center. Johnson’s life and accomplishments would have deserved attention even if Hollywood hadn’t come calling, she suggests.

Kimberly Bloom, director of Langley's Child Development Center, said Katherine Johnson made a positive impact on NASA culture and on America as a whole.

“It’s an important story — how she empowered women of all races,” Bloom said. “And she encouraged kids to learn. She influenced culture here at NASA, but also beyond and made an impact. She certainly is a role model.

“I’d like to thank her for all she’s done not only for NASA but also for this country,” Bloom said.

Katherine Johnson Biography

https://www.nasa.gov/content/katherine-johnson-biography

Date of Birth: August 26, 1918 Hometown: White Sulphur Springs, WV Education: B.S., Mathematics and French, West Virginia State College, 1937 Hired by NACA: June 1953 Retired from NASA: 1986 Actress Playing Role in Hidden Figures: Taraji P. Henson

Being handpicked to be one of three black students to integrate West Virginia’s graduate schools is something that many people would consider one of their life’s most notable moments, but it’s just one of several breakthroughs that have marked Katherine Johnson’s long and remarkable life. Born in White Sulphur Springs, West Virginia in 1918, Katherine Johnson’s intense curiosity and brilliance with numbers vaulted her ahead several grades in school. By thirteen, she was attending the high school on the campus of historically black West Virginia State College. At eighteen, she enrolled in the college itself, where she made quick work of the school’s math curriculum and found a mentor in math professor W. W. Schieffelin Claytor, the third African American to earn a PhD in Mathematics. Katherine graduated with highest honors in 1937 and took a job teaching at a black public school in Virginia.  

When West Virginia decided to quietly integrate its graduate schools in 1939, West Virginia State’s president Dr. John W. Davis selected Katherine and two male students as the first black students to be offered spots at the state’s flagship school, West Virginia University. Katherine left her teaching job, and enrolled in the graduate math program. At the end of the first session, however, she decided to leave school to start a family with her husband.  She returned to teaching when her three daughters got older, but it wasn’t until 1952 that a relative told her about open positions at the all-black West Area Computing section at the National Advisory Committee for Aeronautics’ (NACA’s) Langley laboratory, headed by fellow West Virginian Dorothy Vaughan. Katherine and her husband, James Goble, decided to move the family to Newport News to pursue the opportunity, and Katherine began work at Langley in the summer of 1953. Just two weeks into Katherine’s tenure in the office, Dorothy Vaughan assigned her to a project in the Maneuver Loads Branch of the Flight Research Division, and Katherine’s temporary position soon became permanent. She spent the next four years analyzing data from flight test, and worked on the investigation of a plane crash caused by wake turbulence. As she was wrapping up this work her husband died of cancer in December 1956.

The 1957 launch of the Soviet satellite Sputnik changed history—and Katherine Johnson’s life. In 1957, Katherine provided some of the math for the 1958 document Notes on Space Technology, a compendium of a series of 1958 lectures given by engineers in the Flight Research Division and the Pilotless Aircraft Research Division (PARD). Engineers from those groups formed the core of the Space Task Group, the NACA’s first official foray into space travel, and Katherine, who had worked with many of them since coming to Langley, “came along with the program” as the NACA became NASA later that year. She did trajectory analysis for Alan Shepard’s May 1961 mission Freedom 7, America’s first human spaceflight. In 1960, she and engineer Ted Skopinski coauthored Determination of Azimuth Angle at Burnout for Placing a Satellite Over a Selected Earth Position, a report laying out the equations describing an orbital spaceflight in which the landing position of the spacecraft is specified. It was the first time a woman in the Flight Research Division had received credit as an author of a research report.

In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon to do the work that she would become most known for. The complexity of the orbital flight had required the construction of a worldwide communications network, linking tracking stations around the world to IBM computers in Washington, DC, Cape Canaveral, and Bermuda. The computers had been programmed with the orbital equations that would control the trajectory of the capsule in Glenn’s Friendship 7 mission, from blast off to splashdown, but the astronauts were wary of putting their lives in the care of the electronic calculating machines, which were prone to hiccups and blackouts. As a part of the preflight checklist, Glenn asked engineers to “get the girl”—Katherine Johnson—to run the same numbers through the same equations that had been programmed into the computer, but by hand, on her desktop mechanical calculating machine.  “If she says they’re good,’” Katherine Johnson remembers the astronaut saying, “then I’m ready to go.” Glenn’s flight was a success, and marked a turning point in the competition between the United States and the Soviet Union in space.

When asked to name her greatest contribution to space exploration, Katherine Johnson talks about the calculations that helped synch Project Apollo’s Lunar Lander with the moon-orbiting Command and Service Module. She also worked on the Space Shuttle and the Earth Resources Satellite, and authored or coauthored 26 research reports. She retired in 1986, after thirty-three years at Langley. “I loved going to work every single day,” she says. In 2015, at age 97, Katherine Johnson added another extraordinary achievement to her long list: President Obama awarded her the Presidential Medal of Freedom, America’s highest civilian honor.

Museum Exhibit Reveals the NASA Langley Human Computers from "Hidden Figures"

Sam McDonald NASA Langley Research Center

A new display at the Hampton History Museum offers another view of African-American women whose mathematical skills helped the nation’s early space program soar.

“When the Computer Wore a Skirt: NASA’s Human Computers” opens to the public Saturday, Jan. 21, and focuses on three women — Dorothy Vaughan, Mary Jackson and Katherine Johnson — who were illuminated in Margot Lee Shetterly’s book “Hidden Figures” and the major motion picture of the same name. Located in the museum's 20th century gallery, it was created with support from the Hampton Convention and Visitor Bureau and assistance from NASA's Langley Research Center.

“Langley’s West Computers were helping America dominate aeronautics, space research, and computer technology, carving out a place for themselves as female mathematicians who were also black, black mathematicians who were also female,” Shetterly wrote.

The modestly sized exhibit is comprised of four panels with photos and text along with one display case containing artifacts, including a 1957 model Friden mechanical calculator. That piece of equipment represented state-of-the-art technology when then original human computers were crunching numbers. A three-minute video profiling Johnson —a Presidential Medal of Freedom winner — is also part of the exhibit.

A display case at left contains a 1957 Friden STW-10 mechanical calculator, the type used by NASA human computers including Katherine Johnson. "If you were doing complicated computations during that time, this is what you used," said Hampton History Museum Curator Allen Hoilman. The machine weighs 40 pounds.

Museum curator Allen Hoilman said his favorite artifact is a May 5, 1958 memo from Associate Director Floyd Thompson dissolving the West Area Computers Unit and reassigning its staff members to other jobs around the center.

“It meant that the segregated work environment was coming to an end,” Hoilman said. “That’s why this is a significant document. It’s one of the bookends.”

That document, along with several others, was loaned to the museum by Ann Vaughan Hammond, daughter of Dorothy Vaughan. Hoilman said family members of other human computers have been contacted about contributing artifacts as well.

Ann Vaughan Hammond worked hard to find meaningful items for the display. “She really had to do some digging through the family papers,” Hoilman said, explaining that the women who worked as human computers were typically humble about their contributions. They didn’t save many mementos.

“They never would have guessed they would be movie stars,” Hoilman said.
