Sadly it has a voiceover which makes it annoying to open, but this website has an interesting article discussing the first computer programmers of the modern age – all of whom were women.
I have read before about the “calculators”, women who worked in Universities doing the practical work of solving equations by hand for academic, research or engineering tasks. This website shows how these women became the first programmers. Some of them went on to have significant roles in the development of modern programming, including the concepts and methods underlying it. It’s fascinating that the whole field is now much more male-dominated than it was then … though of course, not surprising.
