Jean (Jennings) Bartik is Notable.

Born in Alanthus Grove in 1924. Daughter of William Smith Jennings and Lula May Spainhower.[1]

When the Electronic Numeric Integrator and Computer (ENIAC) was developed for the purpose of calculating these same trajectories, Bartik applied to become a part of the project and was eventually selected to be one of its first programmers. Bartik and the other five original programmers became extremely adept at running the ENIAC, after learning how the machine worked only by reviewing diagrams of the device and by talking to its engineers: there was no manual. Initially, they were not allowed to see the ENIAC at all since it was still classified and their clearance hadn't gone through, so they had to learn how to program the machine solely through schematic diagrams.

She married William Bartik in 1946; they divorced in 1968. Three children.
