Human computers played integral roles in the World War II war effort in the United States, and because of the depletion of the male labor force due to the Conscription in the United States, many computers during World War II were women, frequently with degrees in mathematics.
In the 1940s, women were hired to examine nuclear and particle tracks left on photographic emulsions. Human computers were involved in calculating ballistics tables during World War I - wikipedia

Following World War II, the National Advisory Committee for Aeronautics (NACA) used human computers in flight research to transcribe raw data from celluloid film and oscillograph paper and then, using slide rules and electric calculators, reduced the data to standard engineering units.
Margot Lee Shetterly's biographical book, ''Hidden Figures (book)'' (made into a Hidden Figures in 2016), depicts African American women who served as human computers at NASA in support of the Friendship 7, the first American manned mission into Earth orbit. NACA had begun hiring black women as computers from 1940.

One such computer was Dorothy Vaughan who began her work in 1943 with the Langley Research Center as a special hire to aid the war effort, and who came to supervise the West Area Computers, a group of African-American women who worked as computers at Langley. Human computing was, at the time, considered menial work.
On November 8, 2019, the Congressional Gold Medal was awarded "In recognition of all the women who served as computers, mathematicians, and engineers at the National Advisory Committee for Aeronautics and the National Aeronautics and Space Administration (NASA) between the 1930s and the 1970s."
As electrical computers became more available, human computers, especially women, were drafted as some of the first Programmer. Because the six people responsible for setting up problems on the ENIAC (the first general-purpose electronic digital computer built at the University of Pennsylvania during World War II) were drafted from a corps of human computers, the world's first professional computer programmers were women, namely: Kathleen Antonelli, Betty Holberton, Marlyn Meltzer, Ruth Teitelbaum, Jean Bartik, and Frances Spence.
