Nicholas Lemann has been the Dean and Henry R. Luce Professor at the Columbia School of Journalism since 2003.

Lemann began his journalism career as a 17-year-old writer for an alternative weekly newspaper there, the Vieux Carre Courier. He graduated magna cum laude from Harvard College in 1976, where he concentrated in American history and literature and was president of the Harvard Crimson.

After graduation, he worked at the Washington Monthly, as an associate editor and then managing editor; at Texas Monthly, as an associate editor and then executive editor; at The Washington Post, as a member of the national staff; at The Atlantic Monthly, as national correspondent; and at The New Yorker, as staff writer and then Washington correspondent.

On September 1, 2003, he became dean of the Graduate School of Journalism at Columbia University, at the end of a process of re-examination of the school's mission conducted by a national task force convened by the university's president, Lee C. Bollinger. During Lemann's time as dean, the Journalism School has launched and completed its first capital fundraising campaign, added 15 members to its full-time faculty, built a student center, started its first new professional degree program since the 1930s, and launched significant new initiatives in investigative reporting, digital journalism, executive leadership for news organizations, and other areas.

Lemann continues to contribute to The New Yorker as a staff writer. He has published five books, most recently "Redemption: The Last Battle of the Civil War" (2006); "The Big Test: The Secret History of the American Meritocracy" (1999), which helped lead to a major reform of the SAT; and "The Promised Land: The Great Black Migration and How It Changed America" (1991), which won several book prizes. He has written widely for such publications as The New York Times, The New York Review of Books, The New Republic, and Slate; worked in documentary television with Blackside, Inc., "FRONTLINE," the Discovery Channel, and the BBC; and lectured at many universities.
