Frances Spence had continued working on the ENIAC in the years after the war, but shortly after her marriage, she resigned to raise a family.

"), all women from similar backgrounds as Spence. Despite her importance as one of the original programmers of the ENIAC, the role that she and the other female programmers took on was largely downplayed at the time due to the stigma that women were not interested in technology.
Photos of the women working on the computer often went without credit in newspapers at the time, and when the ENIAC was completed and unveiled to the public on February 15, 1946, the US Army failed to mention the names of the female programmers who had programmed the machine to run such sophisticated calculations. This further contributed to the perceived disconnect between women and computing.

In 2010, a documentary called, "''
Top Secret Rosies: The Female "Computers" of WWII''" was released. The film centered around in-depth interviews of three of the six women programmers, focusing on the commendable patriotic contributions they made during World War II.The ENIAC team is the inspiration behind the award-winning 2013 documentary ''The Computers''. This documentary, created by Kathy Kleiman and the ENIAC Programmers Project, combines actual footage of the ENIAC team from the 1940s with interviews with the female team members as they reflect on their time working together on the ENIAC. It is the first documentary of a series of three, and parts two and three will be entitled ''The Coders'' and ''The Future-Maker'', respectively.
