About 300 tickets remain for Sunday’s lecture by civil rights activist and Pulitzer Prize-winning journalist Roger Wilkins.

Wilkins, professor of history and American culture at George Mason University, will speak at 8 p.m. Sunday at the Lied Center. He is the second speaker in the four-week Presidential Lecture Series at the Dole Institute of Politics.

Wilkins had a varied career that began as assistant attorney general during the Lyndon Johnson administration. He then wrote for The New York Times and The Washington Post.

While at the Post, he shared a 1972 Pulitzer Prize with Bob Woodward and Carl Bernstein for editorials he wrote about the Watergate scandal.

His books include an autobiography, “A Man’s Life,” written in 1982 and reprinted in 1991, and “Jefferson’s Pillow: The Founding Fathers and the Dilemma of Black Patriotism,” published in 2001, which won the 2002 New Atlantic Independent Booksellers Assn.’s award for adult nonfiction.

Wilkins also has been active in civil rights issues, serving as chairman of the board of trustees of the Africa-America Institute, a member of the NAACP Legal Defense Fund and publisher of the NAACP’s journal “Crisis.”

The lecture is free and open to the public. Vouchers are available at the Lied Center box office from 11 a.m. to 6 p.m. Monday through Friday or by calling 864-2787.

The Lied Center will be opened to those without tickets between 7:30 p.m. and 7:45 p.m. Sunday.

David Gergen, adviser to presidents Nixon, Ford, Reagan and Clinton and frequent television guest, is the next lecturer. He will speak at 8 p.m. Nov. 16. About 150 tickets remain.

Richard Norton Smith, the director of the Dole Institute who leaves Dec. 1 to direct the Abraham Lincoln Presidential Library and Museum in Springfield, Ill., is the final speaker in the series. He’ll talk at 8 p.m. Nov. 23. About 800 tickets remain for his speech, which was a late addition to the Presidential Lecture Series.
