Pioneering NASA mathematician, Katherine Johnson, whose work inspired the story of the 2016 film Hidden Figures, has died at the age of 101. "Our NASA family is sad to learn the news that Katherine Johnson passed away this morning at 101 years old. She was an American hero and her pioneering legacy will never be forgotten," NASA Administrator James Bridenstine announced on Monday. The @NASA family will never forget Katherine Johnson's courage and the milestones we could not have reached without her.
