The other two women are Jennifer Granholm, Governor of Michigan (behind Barack's right shoulder) and Penny Pritzger, CEO Classic Residence by Hyatt (2nd from the left).
UPDATE: apparently there's another woman who appeared with Barack's economic transition team - Laura D'Andrea Tyson, who chaired the Council of Economic Advisers under President Clinton. Laura is one of two possible women nominees for head of Treasury. (The other is Sheila Bair, chair of the Federal Deposit Insurance Corporation, which insures bank deposits up to $250,000.)
They joined an equally esteemed list of men (including the legendary Warren Buffet). You can read the names here.
Why should we care? As reported by Women's ENews:
"Job losses in the wake of the recent economic collapse were concentrated among women, according to data compiled by the Bureau of Labor Statistics in Washington, D.C. At the end of October, the number of unemployed adult females rose from 3.3 million to 3.6 million, a 9 percent increase, according to the Nov. 7 report. The number of unemployed men jumped from 4.8 million to 5 million, a 4 percent rise."
