UPDATED: Shonda Rhimes is among the many paying tribute to Suzanne Patmore Gibbs, the head of Sony Pictures TV’s TriStar Television, who died suddenly at the age of 50.

Patmore Gibbs was passionate about providing more opportunities for female showrunners and directors and was regarded as a champion of distinctive writers and as an executive who nurtured younger and less experienced TV writers. Rhimes was one of those newcomers in the early 2000s. In a tweet, Rhimes wrote Patmore Gibbs was the first exec to say “maybe Shonda could write a TV show” and noted “she fought like hell to get us the chance to make the Grey’s Anatomy pilot. No way to describe this loss.”

Director Paris Barclay, Grey’s Anatomy showrunner Krista Vernoff and more also are remembering Patmore Gibbs. A selection of tweets follows below.
