New York Times Media Critic David Carr collapsed in the newsroom on Thursday, he was then taken to St. Luke's-Roosevelt Hospital, where he was pronounced dead.

The news comes one day after the death of revered 60 Minutes correspondent Bob Simon in a car crash in Manhattan. 

Journalism colleagues expressed surprise and sadness at the news of Carr's death, some noting that it has been a troubling week in the world of media and journalism.

David Folkenflik, National Public Radio media correspondent, tweeted, "A terrible stretch for journalists and those who care about journalism."

Mark Halperin, author and managing editor of Bloomberg Politics, tweeted, "In Latin, we'd call David Carr 'sui generis.' In English, we'd call him an American original. In my gut, I'd call him irreplaceable."

Comedian and TV host Seth Meyers tweeted, "Of all the cats, David Carr was the coolest. He will be missed."

Carr joined the Times in 2002 as a business reporter and wrote his weekly column for the business section of the news organization. His work focused on print, digital, film, radio and television issues.
