To get serious about your thread, though Buda, I suspect that the field has been dominated by women, and yet the big names are all men. Not because men are better, but because that's the way our society accords recognition, to men, instead of women. It's considered an exception when a woman succeeds, not a matter of course that she will.
I suspect that there are a lot of great women designers out there who have had no recognition whatsoever, who've probably been in the trenches doing their thing, but it's the Sagmeisters who get the props, not others. I couldn't really tell you of any good women designers out there, but I'm quite sure that they're there.
