happytune - thought you'd be interested.My personal favourites are Lisa Meitner who discovered atomic fission, and Lynn Margulis who discovered the symbiotic origin of eukaryotes. In both cases their ideas now permeate the disciplines where they struggled to find recognition. Both women had some good ideas and some less-good ones (and the same is true for Ada Lovelace I believe). I think part of acknowledging and celebrating women scientists is not to hold them to an impossible standard of perfection, but to place them within the evolving culture of ideas, just like men.
