The Academy of Achievement brings students face-to-face with extraordinary leaders who have shaped our world. Millions of readers of "The New York Times" turn to Nicholas Kristof's column for firsthand insights into breaking world news. His reporting has taken him to 140 countries, including hot spots such as Iraq, Iran and North Korea. He first joined the Times as an economics correspondent and has since served as the paper's bureau chief in Hong Kong, Tokyo and Beijing and as managing editor of the Sunday Times. Kristof and his wife, Sheryl WuDunn, shared the 1990 Pulitzer Prize for International Reporting for their coverage of the Tiananmen Square democracy movement in China. Kristof uses his column to illuminate issues of poverty, global health, and human rights violations. The Pulitzer committee cited his eyewitness coverage of genocide in Darfur in awarding him a second prize, for Distinguished Commentary, in 2006.
