Annie Easley remembered writing instructions, punching cards, operating computers and later handing work to specialist keypunchers and machine operators. The tasks changed as the Cleveland laboratory grew. Her 2001 oral history gives a working programmer’s account of that transition, including the computations behind research on batteries and launch vehicles.
A job in Cleveland
Born in Birmingham, Alabama, in 1933, Easley joined NACA’s Cleveland laboratory in 1955 after reading a newspaper article about two women employed as human computers. She initially performed numerical calculations for researchers. The US Department of Energy independently records her 1933–2011 life dates and work on Centaur and energy projects. The laboratory later became NASA Lewis Research Center and is now Glenn Research Center. This was a different workplace from the Langley group led by Dorothy Vaughan. (NASA’s 2022 biography; Easley’s oral history.)
NASA’s career account describes early work connected with the planned Plum Brook reactor. Easley continued her education while employed, earning a mathematics degree from Cleveland State University in 1977. Calculation was skilled work before it was transferred into an electronic program; education and experience helped her follow the changing equipment. (NASA biography.)
Cards, languages and shared machines
In the interview, Easley recalls using an IBM 650 with SOAP, then punched-card work with the 704 and later the 360. Her account follows who prepared instructions and who ran them, not just the names of successively larger machines. At first her group operated the equipment themselves; later those responsibilities were shared with other workers. (Oral history, printed p. 32.)
She identifies FORTRAN as the language she used for scientific programming over many years. A researcher could express a numerical method as instructions, submit the cards and inspect the result. Errors could lie in the method, the instructions or their preparation, so getting a completed run was only part of obtaining a useful answer.
Energy and flight work
Easley described computations for battery research, including studies involving a battery-powered vehicle. Her Centaur work concerned a rocket upper stage. NASA’s career history records both energy research and launch-vehicle programming; they were distinct applications within her career. (Oral history, pp. 18–19 and 33; NASA biography.)
Her testimony also records unequal treatment. She recalled being removed from a workplace photograph and described obstacles to training. These are her accounts of particular events, alongside her recollection that good experiences outweighed bad ones. She later served as an equal employment opportunity counsellor and took part in education and outreach. (Oral history, photograph and training passages; NASA biography.)
Easley retired in December 1989 and died in 2011. Katherine Johnson’s flight-path analysis provides another example of mathematics used for spaceflight, while Easley’s account shows the day-to-day organisation of scientific programming. Both form part of women’s contributions to computing, through different laboratories and assignments.
