Liu Xiaobo (2010)

Chinese dissident Liu Xiaobo poses for a photographer in this April 2008 photo. Imprisoned Liu won the 2010 Nobel Peace Prize on Friday, Oct. 8, 2010, for "his long and nonviolent struggle for fundamental human rights," a prize likely to enrage the Chinese government, which had warned the Nobel committee not to honor him.
