Mary Winston Jackson was born on April 9, 1921, in Hampton, Virginia, the daughter of Ella and Frank Winston. She attended Hampton’s all-black schools and graduated with high honors from George P. Phenix Training School in 1937. Five years later, she earned dual bachelor’s degrees in mathematics and physical science from Hampton Institute where she also became a member of the Alpha Kappa Alpha sorority. After college, Mary took on a series of jobs, including teacher, bookkeeper, and receptionist. Then in 1951, she found employment at the National Advisory Committee for Aeronautics (NACA, the predecessor agency to NASA) in Langley, Virginia. She worked at the West Computers section as a research mathematician—known at the time as a “human computer.” In 1953, she moved to the Compressibility Research Division of NACA.

Though President Franklin D. Roosevelt’s Executive Order 8802 prohibited discrimination in the defense industry, Virginia state law still enforced segregation in the workplace. All work facilities had separate restrooms and cafeterias designated “white” or “colored.” In the company cafeteria, whites could select their food choices and sit in a lunchroom. Blacks had to make their food requests to a cafeteria attendant and then go back to their desks and eat, an experience Mary considered an indignity. After several months of “separate and unequal” accommodations, Mary was over it! She had had enough and considered resigning, but a chance encounter with a supervisor changed her mind. After hearing her complaints, he invited her to work for him and she accepted. He quickly saw her potential and encouraged her to take engineering classes. She was eventually promoted to aeronautical engineer, making her NASA’s first black female engineer, and developed expertise working with wind tunnels and analyzing data on aircraft flight experiments.

By 1978, Mary Jackson changed positions to be a human resources administrator. She served as both the Federal Women’s Program Manager in the Office of Equal Opportunity Programs and as the Affirmative Action Program Manager. From then until her retirement in 1985, she helped other women and minorities advance their careers, advising them to study and take extra courses to increase their chances for promotion. During her career, Mary Jackson served on many organizations’ boards and committees, including the Girl Scouts of America, and was honored by numerous charitable organizations for her leadership and service. Mary Jackson was married to Levi Jackson, Sr., a sailor in the U.S. Navy on November 18, 1944, and had two children. She died on February 11, 2005, age 83.

In 2016, the story of Mary Jackson and her NASA colleagues Katherine G. Johnson and Dorothy Johnson Vaughan, who calculated flight trajectories for Project Mercury and the Apollo program in the 1960s, made it to the big screen in Hidden Figures. Janelle Monáe portrays Mary Jackson in the film. In 2018, it was announced that Jackson Elementary in Salt Lake City, Utah, named for President Andrew Jackson, would be renamed Mary W. Jackson Elementary School in honor of the groundbreaking NASA engineer.
