<b>Full coverage:</b> 2011 Nobel Prizes

How a movement of ‘ordinary’ Liberian women changed history.

Sharing the 2011 Nobel Peace Prize are Liberian President Ellen Johnson-Sirleaf; her countrywoman Leymah Gbowee, a peace activist; and Tawakul Karman, a Yemeni human rights leader.

Ralph Steinman, who passed away Friday, will still receive his share of the award because the Nobel committee did not know of his death. He and two others are honored for their work with the immune system.
