@JohnMashey Yes, I know!! Imagine my surprise reading your comment :)

I'm quite young though, but had the pleasure of doing an internship under Jörg Schilling/schily of Schillix, star, cdrecord etc. – and he made sure I had at least some knowledge on the history of UNIX, including how PWB Shell worked (I later fixed a dead lock in his Bosh in the evaluation of PS1). That time was also the time where I learned about Mary Ann Horton, SCCS, etc.

What I find so interesting is that the women % wasn't always so low but also not everywhere, as you write! The % of women at a company/org/field always relates to how they're treated and how their peers behave as well as outside image. It's sad on the one hand that many orgs effectively chose to ignore the issue and have women % decline, but also uplifting to see that we can change!
