Celebrating Katherine Johnson, Dorothy Vaughan, and Mary Jackson
The book takes place from the 1930s through the 1960s, depicting the particular barriers for Black women in science during this time, thereby providing a lesser-known history of NASA. The biographical text follows the lives of Katherine Johnson, Dorothy Vaughan, and Mary Jackson, three mathematicians who worked as computers (then a job description) at NACA and NASA, during the space race. They overcame discrimination there, as women and as African Americans.
Creola Katherine Johnson (née Coleman; August 26, 1918 – February 24, 2020) was an American human computer (job title) whose calculations of orbital mechanics as a NASA employee were critical to the success of the first and subsequent U.S. crewed spaceflights. During her 33-year career at NASA and its predecessor, the National Advisory Committee for Aeronautics, she earned a reputation for mastering complex manual calculations and helped pioneer the use of computers to perform tasks previously requiring humans. The space agency noted her "historical role as one of the first African-American women to work as a NASA scientist".
Johnson's work included calculating trajectories, launch windows, and emergency return paths for Project Mercury spaceflights, including those for astronauts Alan Shepard, the first American in space, and John Glenn, the first American in orbit, and rendezvous paths for the Apollo Lunar Module and command module on flights to the Moon. Her calculations were also essential to the beginning of the Space Shuttle program, and she worked on plans for a human mission to Mars.
Dorothy Jean Johnson Vaughan (September 20, 1910 – November 10, 2008) was an American human computer and computer programmer who worked for the National Advisory Committee for Aeronautics (NACA), and NASA, at Langley Research Center in Hampton, Virginia. In 1949, she became acting supervisor of the West Area Computers, the first African-American woman to receive a promotion and supervise a group of staff at the center.
She later was promoted officially to the position of supervisor. During her 28-year career, Vaughan prepared for the introduction of computers in the early 1960s by teaching herself and her staff the Fortran programming language. She later headed the programming section of the Analysis and Computation Division (ACD) at Langley.
Mary Jackson (née Winston April 9, 1921 – February 11, 2005) was an American aerospace engineer at the National Advisory Committee for Aeronautics (NACA), which in 1958 was succeeded by the National Aeronautics and Space Administration (NASA). She worked at Langley Research Center in Hampton, Virginia, for most of her career. She started as a computer at the segregated West Area Computing division in 1951. In 1958, after taking engineering classes, she became NASA's first black female engineer.
After 34 years at NASA, Jackson had earned the most senior engineering title available. She realized she could not earn further promotions without becoming a supervisor. She accepted a demotion to become a manager of both the Federal Women's Program, in the NASA Office of Equal Opportunity Programs and of the Affirmative Action Program. In this role, she worked to influence the hiring and promotion of women in NASA's science, engineering, and mathematics careers.
