6 powerful women at Davos you may not know — but should by Deena Shanker @FortuneMagazine January 24, 2015, 6:49 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons It’s no secret that Davos has a gender diversity problem. Of the some 2,500 participants in the World Economic Forum’s elite gathering this year, just 17 percent are women. Although organizers tried to increase the numbers by instituting a quota system for large companies — they must bring one woman for every four men — the amount of women only increased by 2 percent since last year. So who are these select women in attendance? Some, such as Chancellor of Germany Angela Merkel and Yahoo YHOO CEO Marissa Mayer, are household names, but we combed the participant list and found so many influential women who are less well known. You may not have heard of the six women listed below, but trust us: you will be impressed by their accomplishments.
