This came up yesterday[1] but if you'd like to know more, Kathy Kleiman's "Proving Ground: The Untold Story of the Six Women Who Programmed the World's First Modern Computer" includes the point of view of Jean Bartik along with the other ENIAC programmers. https://www.hachettebookgroup.com/titles/kathy-kleiman/provi...
I highly recommend "Proving Ground: The Untold Story of the Six Women Who Programmed the World's First Modern Computer" for more context about how the ENIAC came together. It includes the point of view of the programmers of the ENIAC who are often left out of or diminished in other accounts.
