This is how you change perception. From the ground, up. The award winning physicist Dr. Jess Wade is fighting the good fight. From the New York Times:
Fewer than 20 percent of biographies on Wikipedia in English are of women, according to Women in Red, Wikipedia’s gender gap-bridging project. Jessica Wade, a British physicist troubled by that number, made it her mission to help change it.
There’s also a spectacular interview with her on the Wikimedia blog. I loved this bit:
When we hosted a wikithon at Imperial, where I work, lots of members of faculty emailed suggestions of people who deserved a page. I think the stream of friendly tweets has inspired other people too—editing Wikipedia is so easy and rewarding that everyone can get involved, whether it is from their lab, bedroom or office.
