Dorothy Vaughan (September 20 1910 – November 10 2008) was an American mathematician and computer scientist who worked for the National Advisory Committee for Aeronautics (NACA), and later the National Aeronautics and Space Administration (NASA). She is noted for her contributions to the development of electronic computer programming and for her leadership of the West Area Computers, a segregated group of African‑American women mathematicians at the Langley Research Center in Hampton, Virginia. Vaughan’s career and achievements were highlighted in the 2016 book Hidden Figures and its subsequent film adaptation.
Early life and education
Dorothy Jean Johnson was born in Kansas City, Missouri. She attended Wilberforce University, a historically Black university in Ohio, where she earned a Bachelor of Science degree in mathematics in 1929. After graduation, she worked as a teacher before moving to Hampton, Virginia, where she married Lew Vaughan in 1932.
Career at NACA/NASA
In 1943, Vaughan was recruited by NACA to work as a “human computer” in the West Area Computers, a segregated unit composed primarily of African‑American women who performed complex ballistic calculations for aircraft design. She quickly became a senior member of the group and, in 1949, was promoted to Acting Superintendent of the West Area Computers, making her the first African‑American woman to receive a promotion to a supervisory position at NACA.
When NACA transitioned to NASA in 1958, Vaughan continued her work at Langley. She taught herself the FORTRAN programming language and, in 1961, became the first Black woman at NASA to be recognized as a computer programmer. Vaughan contributed to projects involving the launch of the first American satellite, the Mercury and Gemini space programs, and early calculations for the Apollo missions to the Moon.
Later life and legacy
Vaughan retired from NASA in 1971 after a 28‑year career. She remained active in community organizations, including the American Association of University Women and the National Association for the Advancement of Colored People (NAACP). Vaughan died in Hampton, Virginia, at the age of 98.
Posthumously, Vaughan has been recognized for her pioneering role in aerospace engineering and computer science. In 2019, the collective contributions of Vaughan and her West Area Computers colleagues were honored with a Congressional Gold Medal. Her story, along with those of fellow mathematicians Katherine Johnson and Mary Jackson, has become a symbol of the contributions of women and African‑American professionals to U.S. scientific achievement.
