Long-time journalist and newscaster, Gwen Ifill, has passed away at 61.

She was best known for moderating PBS’s talk show Washington Week, in addition to co-anchoring PBS NewsHour. She’s also moderated two vice-presidential debates, the most recent between Sarah Palin and Joe Biden in 2008. Before transitioning to journalism, she wrote for publications including The Washington Post and the New York Times.

Ifill had been undergoing cancer treatment for several months, PBS Newshour said in a release. Paula Kerger, CEO of PBS, talks about Ifill’s grace and commitment to her work in the following statement:

“It is with extreme sadness that we share the news that Gwen Ifill passed away earlier today surrounded by family and friends. Gwen was one of America’s leading lights in journalism and a fundamental reason public media is considered a trusted window on the world by audiences across the nation. Her contributions to thoughtful reporting and civic discourse simply cannot be overstated. She often said that her job was to bring light rather than heat to issues of importance to our society. Gwen did this with grace and a steadfast commitment to excellence. Our sorrow at her passing is a part of our profound gratitude for all that she did for our system and our nation. It was an honor to know Gwen and to work with her. All of us at PBS express our sincere condolences to Gwen’s friends and family.”

D.C. Congresswoman Eleanor Holmes Norton also shared remarks, saying in part, “I felt a special kinship to Gwen, who called the District of Columbia home for much of her professional life. Her expansive talents and brilliant insights, however, made her a world-class journalist. It must also be said that for African Americans and women still climbing to reach the heights of journalism, as Gwen did, her career was an inspirational beacon.”

President Barack Obama expressed his condolences at a press conference this afternoon, and many of her friends and colleagues shared their grievances on social media.
