Twice a week, millions of readers of The New York Times turn to Nicholas Kristof’s column for firsthand insights into breaking news from around the world. His travels as a reporter have taken him to 140 countries, including multiple visits to hot spots such as Iraq, Iran and North Korea. In the course of his travels he has survived wars, plane crashes, malaria, and in Indonesia, a mob carrying human heads on pikes. 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. Week after week, Kristof uses his column to illuminate issues of poverty, global health, and human rights violations. He believes in doing more than writing about the abuses he uncovers, personally intervening to buy the freedom of two enslaved women in Cambodia. The Pulitzer committee cited his eyewitness coverage of the ongoing genocide in Darfur in awarding him a second prize, for Distinguished Commentary, in 2006.
