Katherine G. Johnson, the mathematician whose calculations helped propel U.S. astronauts into space and who was the subject of an Academy Award-nominated film, has died, NASA confirmed. She was 101.Mathematician Katherine Johnson at work at NASA’s Langley Research Center in Hampton, Virginia, in 1980.

Still, wielding little more than pencils, slide rules and rulers, Johnson and her colleagues helped send Americans into space.Johnson in the press room during the Academy Awards in 2017.

I’m as good as anybody, but no better.”Related coverage: TPG honors Katherine Johnson, the woman who helped propel Americans to spaceTheir stories, and Johnson’s, went mostly unnoticed until the 2016 movie, “Hidden Figures.” Taraji P. Henson portrayed Johnson, and Octavia Spencer and Janelle Monae starred as Johnson’s colleagues at NASA. The movie received three Academy Award nominations, including for Best Picture, and won Best Movie at the BET Awards.Johnson received The Points Guy’s Lifetime Achievement award at the 2019 TPG Awards. At the December 9 awards ceremony, TPG honored Mrs. Johnson for her contributions to aeronautics. Her children accepted on her behalf. In 2015 she received the Presidential Medal of Freedom from President Barack Obama.In 2017, NASA dedicated a building to Johnson, called the Katherine G.

In her rural hometown, formal education for black students ended in the eighth grade but she went on to earn a graduate degree at West Virginia University.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

After graduate school, Ms. Johnson joined Langley Research Center in Hampton, as a research mathematician for the National Advisory Committee for Aeronautics, according to her NASA biography. She worked at the agency from 1953 until 1986.Johnson correctly calculated the trajectory for the trip that saw Alan Shepard become the first American in space. Less than a year later, the astronaut John Glenn (who would later become a U.S. senator) personally requested that Johnson recheck the calculations before his flight, during which he became the first American to orbit the Earth.Upon her death, NASA honored Johnson in several tweets, with one reading, “[n]o longer a Hidden Figure, her bravery and commitment to excellence leaves an eternal legacy for us all.”In a statement, the agency said that Johnson “helped our nation enlarge the frontiers of space even as she made huge strides that also opened doors for women and people of color.”The NAACP also honored Johnson on Twitter, saying, “Katherine Johnson was an inspiration to generations of people, as she worked to break down both racial and gender barriers.”https://www.instagram.com/p/B89NnoepsKs/?igshid=hiyu3x5rmq7nPresident Barack Obama presents Johnson with the Presidential Medal of Freedom in 2015 at the White House.
