Pulitzer Prize-winning journalist Claude Sitton, a pioneer in covering the civil rights movement in the South, died Tuesday in Atlanta, according to his son. He was 89. Sitton's son Clint Sitton said his father had been in hospice care for heart failure. The Georgia-born journalist began reporting for the New York Times in 1958, covering the civil rights movement as it emerged in the South. He later became the Times' national news editor and then served as the editor of The News & Observer in Raleigh, N.C. Sitton won a Pulitzer Prize in 1983 for his commentary at the Raleigh newspaper. During the early 1990s, Sitton taught at Emory University, where he helped establish a journalism program and served as a member of the Board of Counselors of Emory's Oxford College.
