Katherine Johnson was a NASA mathematician who performed a key function in a number of NASA missions in the course of the Area Race, together with calculating the trajectory wanted to get the Apollo 11 mission to the moon and again.Â
As a black girl working for NASA within the Fifties and ’60s, Johnson overcame social boundaries and racial discrimination.Â
Her spectacular profession was the topic of the 2016 ebook and film “Hidden Figures.”Â

Johnson’s highway to NASA
Johnson was born in 1918 in White Sulphur Springs, West Virginia, the youngest of 4 kids. From a really younger age, she had a fascination with numbers, which might lead her to defy all expectations all through her life. “I counted the whole lot. I counted the steps to the highway, the steps as much as church, the variety of dishes and silverware I washed … something that could possibly be counted, I did,” mentioned Johnson in accordance with a NASA history article (opens in new tab). mentioned throughout an interview with NASA in 2015.Â
Johnson’s hometown didn’t supply public education for black kids previous eighth grade, so her household moved 120 miles (193 kilometers) away in order that she may attend highschool. She graduated highschool at simply 14 and faculty at 18, securing levels in each arithmetic and French from the traditionally black West Virginia State School.Â
Whereas in class, her potential was clear to her academics. One in all her professors, William Schieffelin Claytor, inspired Johnson to change into a analysis mathematician and created a geometry class only for her. After educating for a number of years, Johnson was accepted to West Virginia College’s graduate math program, and in 1939, she grew to become the primary black girl to attend the varsity.Â
A yr into her coursework, she left to boost her three daughters. Then, in 1952, a relative instructed her about an thrilling new alternative: The Nationwide Advisory Committee for Aeronautics (NACA), the predecessor to NASA, was hiring black girls to resolve math issues. Johnson utilized straight away. She was quickly employed as a “laptop” on the Langley Research Center (opens in new tab), tasked with performing and checking calculations for flight exams.
“Earlier than these large IBM mainframe computer systems got here in [the NACA] actually relied on human beings to do the maths for calculating trajectories. Katherine actually does play a job in that human computing lab,” NASA historian Brian Odom instructed our sister publication All About Historical past.
Along with excelling at her work, Johnson was exceptionally curious and assertive, all the time questioning her colleagues and asking to be included in essential conferences. When she began at NACA, Johnson and her black colleagues had been required to work, eat and use restrooms individually from the white staff. However Johnson ignored the racial and gender boundaries of the time and have become the primary girl within the Flight Analysis Division to be credited as an creator on a analysis report.
“We would have liked to be assertive as girls in these days — assertive and aggressive — and the diploma to which we needed to be that means trusted the place you had been. I needed to be,” Johnson said in 1999 (opens in new tab) of her time working for the NACA and later NASA.
NACA turns into NASA
In 1958, NACA grew to become NASA. Johnson’s time working for NASA would show to be a extra optimistic expertise on the subject of racial segregation given NASA’s variety insurance policies. “As soon as NASA comes on-line in 1958 you see the construct up of quite a lot of centres within the south. In the present day we’ll consider Johnson Space Centre in Houston, Marshall Space Flight Centre in Huntsville, Alabama, and the Kennedy Space Centre in Florida, however there have been different areas throughout the south too close to New Orleans and South Mississippi. So mainly what’s taking place is NASA is constructing an enormous infrastructure within the time interval from 1958 to 1963, on the construct up for Apollo, within the Jim Crow segregated south,” Odom mentioned.
“The federal authorities, from the very starting of this course of, is dedicated to equal employment alternative and that is one thing that John F Kennedy in March of 1961, with a brand new government order, actually makes a key a part of this programme. So equal employment turns into an enormous factor and for the primary time in that government order, we see that time period “affirmative motion”. It isn’t simply that it’s important to not discriminate, however you additionally should have a optimistic plan for affirmative motion, by which you exhibit that you take the steps essential to deliver these jobs to African Individuals,” Odom added.
Notable achievements

With the Soviet Union launching the Sputnik satellite in 1957, the US was decided to not fall behind and so the Space Race started.Â
Johnson’s ardour was geometry, which was helpful for calculating the trajectories of spacecraft. For NASA’s 1961 Mercury mission, she knew that the trajectory could be a parabola, a sort of symmetrical curve. So when NASA needed the capsule to come back down at a sure place, she was not deterred.Â
“You inform me once you need it and the place you need it to land, and I am going to do it backwards and inform you when to take off,” Johnson mentioned according to a NASA (opens in new tab). Subsequent orbital missions had been extra sophisticated, with extra variables involving the place and rotation of the Earth, so Johnson used a celestial coaching system to carry out her calculations.
Johnson was tasked with calculating the trajectory for Alan Shepard‘s historic flight, throughout which he grew to become the primary American to achieve space. She additionally confirmed the trajectory to ship the primary American into orbit across the Earth. By this time, NASA had begun utilizing digital computer systems to carry out these duties, however the machines could possibly be somewhat temperamental. Earlier than his Friendship 7 mission, astronaut John Glenn requested that Johnson personally recheck the calculations by hand. “If she says they’re good, then I am able to go,” Glenn mentioned, according to Johnson’s recollection of the event (opens in new tab).
The following problem was to ship people to the moon, and Johnson’s calculations helped sync the Apollo 11 lunar lander with the moon-orbiting command and repair module to get the astronauts again to Earth. She additionally proved invaluable on the Apollo 13 mission, offering backup procedures that helped make sure the crew’s protected return after their craft malfunctioned. She later helped to develop the space shuttle program and Earth sources satellite, and she or he co-authored 26 analysis reviews earlier than retiring in 1986.
Johnson’s legacy
Johnson spent the next years chatting with college students about her extraordinary profession, encouraging them to pursue STEM training. “Some issues will drop out of the general public eye and can go away,” she mentioned on the NASA Trailblazers and Legends STEM Conference in Cape Canaveral, Florida in 2010 (opens in new tab). “There’ll all the time be science, engineering and know-how. And there’ll all the time, all the time be arithmetic. The whole lot is physics and math.”
She and her colleagues grew to become well-known with the publication of “Hidden Figures” (William Morrow and Co., 2016) by Margot Lee Shetterly and the discharge of the blockbuster film of the identical identify, which starred Taraji P. Henson, Janelle Monáe and Octavia Spencer as Johnson and her colleagues Mary Jackson and Dorothy Vaughan. The discharge of “Hidden Figures” made Johnson some of the celebrated black girls in space science and a hero for these calling for motion in opposition to sexism and racism in science and engineering.
In 2015, President Barack Obama awarded Johnson the Presidential Medal of Freedom, America’s highest civilian honor. And in 2016, the NASA Langley facility at which Johnson labored renamed a building in her honor: the Katherine G. Johnson Computational Analysis Facility.Â
In 2019, Johnson instructed her personal story for younger readers in a ebook known as “Reaching for the Moon” (Atheneum Books for Younger Readers).
“Each time engineers would hand me their equations to judge, I might do greater than what they’d requested. I would attempt to assume past their equations. To make sure that I would get the reply proper, I wanted to grasp the considering behind their selections and selections,” she wrote.
“I did not enable their side-eyes and aggravated seems to be to intimidate or cease me. I additionally would persist even when I assumed I used to be being ignored. If I encountered one thing I did not perceive, I would just ask. … I simply ignored the social customs that instructed me to remain in my place.”
Johnson died on Feb. 24, 2020, at age 101. NASA Administrator Jim Bridenstine introduced her dying and promised that her legacy could be remembered.
“At NASA, we’ll always remember her braveness and management and the milestones we couldn’t have reached with out her,” Bridenstine mentioned. “We are going to proceed constructing on her legacy.”
“She performed an enormous function in NASA all through her profession and is somebody we (NASA) actually look again on fondly,” Odom mentioned.
