Johnson’s computations have influenced every major space program from Mercury through the Shuttle program. Johnson was hired as a research mathematician at the Langley Research Center with the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, after they opened hiring to African-Americans and women. Johnson exhibited exceptional technical leadership and is known especially for her calculations of the 1961 trajectory for Alan Shepard’s flight (first American in space), the 1962 verification of the first flight calculation made by an electronic computer for John Glenn’s orbit (first American to orbit the earth), and the 1969 Apollo 11 trajectory to the moon. In her later NASA career, Johnson worked on the Space Shuttle program and the Earth Resources Satellite and encouraged students to pursue careers in science and technology fields.

Katherine Johnson, who hand-crunched the numbers for America’s first manned space flight – a feat that finally got its Big Screen acknowledgement just two years ago, turned 100 on Sunday, August 26, 2018.

“[On Sunday], we celebrate Alpha Kappa Alpha’s own, Katherine Johnson. She’s credited with crunching the numbers by hand that allowed NASA to launch the first U.S. astronauts into space,” leaders of the Alpha Kappa Alpha said in a statement.

“We are women of many first. First and finest.”

Many others paid tribute via statements and social media.

“If you haven’t seen the movie about what she and other brilliant Black women at NASA accomplished, be sure to watch the fabulous movie, ‘Hidden Figure,’ in her honor,” said comic book writer Grace Randolph.

“I stand on your shoulders,” said Dr. Camille Alleyne. “You blazed the trail which I and so many have had the privilege to walk on … Katherine, you are my hero. I love, honor and salute you,” Alleyne said.

Dr. Benjamin F. Chavis Jr., president and CEO of the National Newspaper Publishers Association (NNPA), also paid homage to Johnson.

“Katherine Johnson’s historic contributions to the evolution of applied mathematics and aerospace science epitomizes her genius to overcome the scientific challenges of her generation,” Chavis said.

“Today, African American women in particular should be inspired by the example of Katherine Johnson in STEM career fields,” Chavis said.

“The NNPA salutes Johnson’s transformative legacy that is no longer hidden.”

The recipient of the 2015 National Medal of Freedom, and a 2016 People Magazine honoree as being among the 25 Women Changing the World, Johnson enjoyed a brilliant 33-year career at NASA and her life story finally was told on the big screen in “Hidden Figures,” the award-winning movie that starred Taraji P. Henson, Octavia Spencer and Janelle Monáe.

In an earlier interview, she told NNPA Newswire that she missed working.

“I’d go back now,” she said.

After leaving her teaching job in 1953, Johnson began working for NASA and was able to calculate the trajectory for numerous space missions, including for the space flight of Alan Shephard, the first American in space and the trajectory for the famed 1968 Apollo 11 flight to the Moon.

“I’d do them over if I had to. I’d do anything for anyone,” she said.

At an early age, Johnson developed enviable math skills so much so that even NASA officials wrote a story about her titled, “The girl who loved to count.”

“I counted everything. I counted the steps to the road, the steps up to church, the number of dishes and silverware I washed … anything that could be counted, I did,” Johnson said.

“I entered college, I was 15. I was going to be a math teacher because that was it. You could be a math teacher or a nurse but I was told I would make a good research mathematician and they had me take all of the courses in the catalogue,” she said.

When Astronaut John Glenn went to the moon, Johnson said her “Hidden Figures” crew acted as the computer for the mission. She said calculating everything involved in the flight became like a geometry problem.

“I felt most proud of the success of the Apollo mission. We had to determine so much. Where you were, where the moon would be and how fast the astronauts were going,” Johnson said.

“We were really concerned but the astronaut had to do it just as we laid it out. I was looking at the television and hoping that were right,” she said.

Born in 1918 in West Virginia, Johnson was a research mathematician, who by her own admission, was simply fascinated by numbers, according to her biography posted by NASA.

By the age of 10, Johnson was a high school freshman – an amazing feat in an era when school for African-Americans normally stopped at eighth grade.

Her father was determined that Johnson would have a chance to meet her potential. “He drove the family 120 miles to Institute, West Virginia, where I could continue my education through high school,” she said.

An achiever at the highest level, Johnson graduated from high school at 14 and from college at 18. By 1953, the growing demands of early space research meant there were openings for African American computers at Langley Research Center’s Guidance and Navigation Department – and Johnson found the perfect place to put her extraordinary mathematical skills to work.

Glenn requested that she personally recheck the calculations made by the new electronic computers before his flight aboard Friendship 7 – the mission on which he became the first American to orbit the Earth.

She continued to work at NASA until 1986.

Her calculations proved as critical to the success of the Apollo Moon landing program and the start of the Space Shuttle program, as they did to those first steps on the country’s journey into space, according to NASA.

Still, Johnson said the book, the Academy Award nominated movie and her celebrated work with NASA aren’t her greatest accomplishments.

“Just staying alive is the greatest accomplishment,” she said.

In a statement, NASA also praised Johnson.

“Today, retired NASA Langley mathematician Katherine Johnson makes her 100th trip around the sun as she celebrates her birthday.”
