Wartime Computing and The Invention of Electronic Computing

Human computers have 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 draft, many computers during World War II were women, frequently with degrees in mathematics. In the Manhattan Project, human computers, working with a variety of mechanical aids, assisted numerical studies of the complex formulas related to nuclear fission. Because the six people responsible for setting up problems on the ENIAC (the premiere 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, paving the way for careers in data processing as socially acceptable for women in an era of gender roles. These six computers-turned-computer-programmers were Kay McNulty, Betty Snyder, Marlyn Wescoff, Ruth Lichterman, Betty Jean Jennings, and Fran Bilas.

Following World War II, the 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, reduce it to standard engineering units.
