Specific role models that may be relevant: jeri Ellsworth, grace hopper, Hilary mason, Jessica Evans, Kira radinsky, Joanna rutkowska, Limor Fried (LadyAda). Just a random list off the top of my head.
I read Amelia Earheart's bio when I was in sixth grade. It doesn't necessarily have to be women in tech per se, but it helps to be a woman not in the entertainment industry. Most of our wealthy, "successful" female role models are actresses and singers. Sex appeal is a large part of their career and how they make their money. This is very problematic if you want a business career. Looking sexy at work causes all kinds of problems in more conservative environments. I think a lot about the fact that women have basically two models for how to look successful: Pretty women who are often wives or entertainers where highlighting their femininity or sexuality is a big part of it, or trying to dress like a man. In America at least, we don't have a lot of good role models for what successful women in business or government look like.
I think about this a lot and I think this is a big source of problems for women trying to figure out how to make it in business (or government or something other than as entertainers or someone's wife).
