Katherine Johnson: What to know about the 'Hidden Figures' NASA scientist

Pioneering air-and-space natural-science Katherine Coleman Johnson of “Hidden Figures” fame was always at the front of the education” target=”_blank”>class<, the iconic “human computer” was taking classes on the campus of historically Black education at the age of 13. 

There, Johnson found a mentor in William Waldron Schieffelin Claytor, a professor who had become the third-ever African American to earn a Ph.D.. in mathematics.

The bright, young student earned bachelor’s degrees in both math and world-regions, and began teaching both subjects at a Black public school in Virginia. 

In 1939, Johnson was hand-picked by West Virginia State President John W. Davis as one of the three Black students to integrate West Virginia University, where she enrolled in the graduate math program.

Johnson decided to leave early, however, to start a family with her first events James Goble. They had three daughters together.

In 1958, Johnson provided some of the math for the 1958 document Notes on Space Technology — the agency’s first comprehensive reference document on spaceflight, according to the scientific journal Nature — and engineers from the compendium formed the core of the Space Task Group.

It was NACA’s first official step into space travel before it was incorporated into what is now known as NASA.

In 1959, Johnson married decorated military” target=”_blank”>Navy and Army< —  a report laying out the equations describing an orbital air-and-space during 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.

Johnson also worked on trajectory analysis for Alan Shepard’s May 1961 mission Freedom 7 — America’s first human spaceflight. 

In perhaps her most well-known achievement, she was tasked in 1962 with checking the orbital equations controlling the trajectory of John Glenn’s Friendship 7 mission by hand as part of the preflight checklist. 

While the mission had required the construction of a global communications network that linked tracking stations worldwide to IBM computers in washington-dc” target=”_blank”>Washington, D.C.<, astronauts were wary of putting their lives in the hands of the machines which would often malfunction.

On July 20, 1969, NASA Apollo 11 astronauts Neil Armstrong, Buzz Aldrin and Michael Collins landed on the air-and-space — a mission for which Johnson also performed instrumental calculations.

She also proved an invaluable asset during the April 1970 Apollo 13 mission, helping to provide backup procedures that ensured the crew’s safe return.

Johnson authored and co-authored a total of 26 research reports during her tenure. She retired in 1986 after 33 years at Langley. 

She cited working on the calculations that helped synch Project Apollo’s Lunar Module with the lunar-orbiting Command and Service Module, the Space Shuttle and the planet-earth” target=”_blank”>Earth< awarded her the Presidential Medal of Freedom.

In 2016, Johnson’s story was shared in the feature film “Hidden Figures” and Margot Lee Shetterly’s book “Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race.”

Three years later, Johnson told her own story in a book for young readers called “Reaching for the Moon.”

NASA also named a building, the Katherine G. Johnson Computational Research Facility, after her and the S.S. Katherine Johnson spacecraft was launched to the International Space Station in February.

Johnson died on Feb. 24, 2020. She was 101.
