THE NEW YORK TIMES is to be edited by a woman for the first time in its 160-year history, after its executive editor Bill Keller announced he would step down this summer to be replaced by current managing editor Jill Abramson.

Abramson joined the Times in 1997 after working for nearly a decade at The Wall Street Journal. She was the Times’ Washington editor and bureau chief before Keller picked her to become the managing editor in 2003 when he himself took the top job.

She said in a statement that she was grateful for the opportunity to lead the paper, calling it “a dream job.”

Keller, who presided over the newsroom during a time of enormous change within the industry, will stay on as a full-time writer for The New York Times Magazine and the newspaper’s Sunday opinion and news section.

“Bill came to me several weeks ago and told me that he felt the time had come for him to step down from the role of executive editor,” Times chairman and publisher Arthur Sulzberger Jr said in a statement. “I accepted his decision with mixed emotions.”

Dean Baquet, now an assistant managing editor and Washington bureau chief at the paper, will succeed Abramson as managing editor.

The Times said the changes are effective as of September 6.

Keller took over as the top editor in 2003 in the wake of a plagiarism scandal involving reporter Jayson Blair. His initial tasks included healing the damage from that episode and dealing with the industry’s painful transition as the finances of print newspapers eroded and readers increasingly got their information online.

During Keller’s tenure, the Times continued its tradition of prize-winning coverage and engaged in confrontations with two presidential administrations over state secrets.

During the presidency of George W. Bush, the Times revealed efforts by the National Security Agency to monitor phone calls without warrants. During Barack Obama’s tenure, it published secret U.S. diplomatic cables and military communications obtained by WikiLeaks.

The paper also underwent some soul searching about the accuracy of its coverage during the run-up to the Iraq war, during which it published stories by reporter Judith Miller about the alleged presence of weapons of mass destruction that were later discredited.

Keller said in a statement that it had been a “privilege to work alongside the world’s finest journalists during these exhilarating years of tumult and transformation.”

“I wanted to move on when the newsroom felt strong in its journalism and secure in its future,” he said.
