Katherine Johnson, who was featured in a 2016 movie chronicling the work of African-American women who helped to put men in space during the Cold War, died on Saturday, People reports. She was 101.

Johnson, one of the women who put men in space with her calculations, worked at Langley Research Center in Hampton, Virginia, a city where the Navy’s first African-American pilot and the first black Navy submarine officer both grew up. She was there from 1943 to 1964, and was the first woman ever to graduate from Westinghouse’s program for black women, according to People.

On Feb. 7, 2016, Jenkins attended the White House for the premiere of the movie “Hidden Figures.” Though the screening was private, fellow cast member Octavia Spencer described Katherine to People as “the rest of us who are not black,” referring to Johnson. The movie, which focused on three women who went into physics at Langley Research Center, became an Oscar favorite for its director, Theodore Melfi, and stars Taraji P. Henson, Octavia Spencer, and Janelle Monae.
