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

Johnson’s street 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 every thing. I counted the steps to the street, the steps as much as church, the variety of dishes and silverware I washed … something that could possibly be counted, I did,” mentioned Johnson based on a NASA historical past article (opens in new tab). mentioned throughout an interview with NASA in 2015.
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 might 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 Faculty.
Whereas at school, her potential was clear to her lecturers. One in every of her professors, William Schieffelin Claytor, inspired Johnson to turn into a analysis mathematician and created a geometry class only for her. After instructing for just a few 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.
A yr into her coursework, she left to boost her three daughters. Then, in 1952, a relative informed her about an thrilling new alternative: The Nationwide Advisory Committee for Aeronautics (NACA), the predecessor to NASA, was hiring black ladies to unravel math issues. Johnson utilized instantly. She was quickly employed as a “laptop” on the Langley Analysis Middle (opens in new tab), tasked with performing and checking calculations for flight checks.
“Earlier than these massive IBM mainframe computer systems got here in [the NACA] actually relied on human beings to do the mathematics for calculating trajectories. Katherine actually does play a job in that human computing lab,” NASA historian Brian Odom informed 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 necessary conferences. When she began at NACA, Johnson and her black colleagues have been required to work, eat and use restrooms individually from the white workers. However Johnson ignored the racial and gender obstacles 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 wanted to be assertive as ladies in these days — assertive and aggressive — and the diploma to which we needed to be that manner relied on the place you have been. I needed to be,” Johnson mentioned 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 almost about racial segregation given NASA’s range insurance policies. “As soon as NASA comes on-line in 1958 you see the construct up of numerous centres within the south. Immediately we’ll consider Johnson House Centre in Houston, Marshall House Flight Centre in Huntsville, Alabama, and the Kennedy House Centre in Florida, however there have been different areas throughout the south too close to New Orleans and South Mississippi. So principally 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 govt 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 govt order, we see that time period “affirmative motion”. It is not simply that you must not discriminate, however you additionally must have a optimistic plan for affirmative motion, wherein you exhibit that you take the steps essential to convey these jobs to African Individuals,” Odom added.

With the Soviet Union launching the Sputnik satellite tv for pc in 1957, the US was decided to not fall behind and so the House Race started.
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 can be a parabola, a kind of symmetrical curve. So when NASA needed the capsule to return down at a sure place, she was not deterred.
“You inform me if you need it and the place you need it to land, and I will do it backwards and inform you when to take off,” Johnson mentioned based on a NASA (opens in new tab). Subsequent orbital missions have been extra difficult, with extra variables involving the place and rotation of the Earth, so Johnson used a celestial coaching gadget 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 house. 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 a bit 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, based on Johnson’s recollection of the occasion (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 secure return after their craft malfunctioned. She later helped to develop the house shuttle program and Earth sources satellite tv for pc, and she or he co-authored 26 analysis reviews earlier than retiring in 1986.
Johnson spent the next years chatting with college students about her extraordinary profession, encouraging them to pursue STEM schooling. “Some issues will drop out of the general public eye and can go away,” she mentioned on the NASA Trailblazers and Legends STEM Convention 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. Every part 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 title, 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 one of the vital celebrated black ladies in house 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 constructing in her honor: the Katherine G. Johnson Computational Analysis Facility.
In 2019, Johnson informed her personal story for younger readers in a e book referred to 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 might attempt to suppose past their equations. To make sure that I might get the reply proper, I wanted to know the pondering behind their selections and selections,” she wrote.
“I did not enable their side-eyes and aggravated seems to intimidate or cease me. I additionally would persist even when I believed I used to be being ignored. If I encountered one thing I did not perceive, I’d simply ask. … I simply ignored the social customs that informed me to remain in my place.”
Johnson died on Feb. 24, 2020, at age 101. NASA Administrator Jim Bridenstine introduced her loss of life and promised that her legacy can be remembered.
“At NASA, we are going to 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.
