Gwen was a standard bearer for courage, fairness and integrity in an industry going through seismic change.

She was a mentor to so many across the industry and her professionalism was respected across the political spectrum.

She had a tremendous combination of warmth and authority.

We will forever miss her terribly.

Her contributions to thoughtful reporting and civic discourse simply cannot be overstated.

Gwen did this with grace and a steadfast commitment to excellence.

It was an honor to know Gwen and to work with her.

All of us at PBS express our sincere condolences to Gwens friends and family.

The veteran journalist has covered several presidential campaigns and moderated the 2004 and 2008 vice-presidential debates.
