The Times' former executive editor, Howell Raines, and his managing editor, Gerald Boyd, resigned June 5 after internal battles that were touched off by the revelation that former reporter Jayson Blair fabricated and plagiarized his way through a series of articles.
In this morning's statement, Times Publisher Arthur Sulzberger Jr. said, "I am grateful that Bill has accepted this new challenge and am confident that in the years to come, he will help us build on The Times' unparalleled tradition of journalistic excellence."
The newspaper company said that in the weeks ahead, Mr. Keller will be evaluating the newsroom operation and management systems.
The 54-year-old Mr. Keller has been with the Times since 1984 and, as a reporter, received a 1989 Pulitzer Prize for his coverage of events in the Soviet Union. He has been a senior writer for the magazine and an op-ed columnist for the past three years. He has also served as the paper's managing editor, foreign editor and chief of the South African bureau.
