NEW YORK — Gwen Ifill, a groundbreaking journalist who covered the White House, Congress, and national campaigns during three decades for The Washington Post, The New York Times, NBC, and, most prominently, PBS, died on Monday at a hospice in Washington. She was 61.
The cause was complications of uterine cancer, her brother Roberto said.
In a distinguished career, Ms. Ifill was in the forefront of a journalism vanguard as a black woman in a field dominated by white men.
She achieved her highest visibility most recently, as the moderator and managing editor of the public-affairs program “Washington Week” on PBS and the co-anchor and co-managing editor, with Judy Woodruff, of “PBS NewsHour,” competing with the major broadcast and cable networks for the nightly news viewership. They were the first all-female anchor team on network news.
Last spring, she and Woodruff were the moderators of a Democratic primary debate between Hillary Clinton and Senator Bernie Sanders, reprising a role Ms. Ifill performed solo between sparring vice presidential candidates in the 2004 and 2008 general election campaigns.
She was also the author of “The Breakthrough: Politics and Race in the Age of Obama,” a book published the day President Obama was inaugurated in 2009.
Speaking at a news conference on Monday, the president said, “Gwen was a friend of ours, she was an extraordinary journalist, she always kept faith with the fundamental responsibilities of her profession: asking tough questions, holding people in power accountable, and defending a strong and free press that makes our democracy work.”
Woodruff, in a phone interview on Monday, described Ms. Ifill as “a fiend about facts” who “loved storytelling and loved helping people understand what was going on in the world around them.”
She added, “For young women of color looking for a role model, she was it.”
Sara Just, executive producer of “NewsHour,” called Ms. Ifill “a standard-bearer for courage, fairness, and integrity in an industry going through seismic change,” adding, “She was a mentor to so many across the industry, and her professionalism was respected across the political spectrum.”
Ms. Ifill had taken a monthlong leave from her PBS programs this year without disclosing her medical condition. She went on leave again a week ago, missing election-night coverage.
On Oct. 7, though, in an online column for PBS titled “The End Is in Sight,” she volunteered some parting wisdom for candidates that, unwittingly, might have proved prescient for Clinton.
“Once a candidate, they can no longer claim outsider status, and he or she begins to look more ambitious than chaste,” Ms. Ifill wrote. “Hillary Clinton was a popular secretary of state, but now she is just Hillary Clinton. There’s something about actually wanting a thing that makes voters think less of you.”
The daughter of Caribbean immigrants, Ms. Ifill said she knew since she was 9 and growing up in the tumultuous 1960s that she wanted to be a journalist.
“I was very conscious of the world being this very crazed place that demanded explanation,” she recalled in a 2011 interview with the Archive of American Television.
“I didn’t see a whole lot of people who looked like me doing it on television,” she added, but “you get used to being underestimated.”
“I got my first job by exceeding expectations,” she said, and she just kept going: “This is the way it is, how do I get around it, get through it, surprise them.”
Gwendolyn L. Ifill (she loathed her middle name and refused to reveal it) was born in New York, to the former Eleanor Husband and Oliver Urcille Ifill Sr., an African Methodist Episcopal minister.
The fifth of six children, she was raised, as her father was periodically reassigned, in Queens, Staten Island, Manhattan, Buffalo, Pennsylvania, and Massachusetts, in church parsonages and stints in federally subsidized housing.
“I knew who these people were because they were me,” she said.
Being a preacher’s daughter, she said, “means you always have to be good.”
Ms. Ifill never married. In addition to her brother Roberto, an economics professor, she leaves another brother, Earle, a minister; and a sister, Maria Ifill Philip, who is retired from the State Department.
She graduated in 1977 with a bachelor of arts degree from Simmons College, an all-women’s school in Boston, where she majored in communications.
“She was a great friend to Simmons, and she was always very available to us,” said Helen Drinan, the school’s president, who knew her personally.
“She was very encouraging to young women journalists,” Drinan said. “She really always made her connections to Simmons and talked up her Simmons roots.”
Drinan described Ms. Ifill as a “big thinker” who was a fantastic role model for women.
“She was grounded in this humility and a kind of friend-level connection that was always real,” Drinan said.
Ms. Ifill was the school’s commencement speaker in 2009.
“She was a great commencement speaker, as you would imagine. The students just adored her,” Drinan said.
Ms. Ifill interned at The Boston Herald-American, then wrote about food there before going on to cover education in the aftermath of the school busing integration tumult. Politics, she learned, pervaded every aspect of public policy.
In Baltimore, she was assigned to report on local politicians — most of whom, she said, she found to be committed to public service — and covered her first presidential campaign for The Washington Post. She was usually assigned to losing candidates who, aware of her assignment, were none too happy to see her coming.
After reporting for The Post from 1984 to 1991, she joined The Times, where she was a White House correspondent and covered Bill Clinton’s impeachment. In 1994, Tim Russert recruited her to cover Capitol Hill for NBC. On her first assignment, she forgot to take a cameraman along.
In 2004, she moderated the debate in which Senator John Edwards criticized Vice President Dick Cheney’s former employer, the Halliburton Co., prompting Cheney to plead, “I can respond, Gwen, but it’s going to take more than 30 seconds.”
“Well,” she replied, “that’s all you’ve got.”
Ifill joined “Washington Week” and “PBS NewsHour” in 1999.
Her 2008 campaign coverage earned her the George Foster Peabody Award. In 2012, she was inducted into the National Association of Black Journalists’ Hall of Fame. Last year, she received the Fourth Estate Award from the National Press Club. She was scheduled to receive the John Chancellor Award for Excellence in Journalism from the Columbia University Graduate School of Journalism this week.Globe correspondent Dylan McGuinness contributed to this obituary.
