New York Times journalist David Carr died Thursday. He was 58.
Times staffers confirmed his death to BuzzFeed News shortly before the paper published his obituary.
In a note to employees, Executive Editor Dean Baquet said Carr "died suddenly tonight after collapsing in the newsroom."
Carr's wife and one of his daughters were joined by a group of Times staffers at the hospital, Baquet added.
"He was the finest media reporter of his generation, a remarkable and funny man who was one of the leaders of our newsroom," Baquet wrote.
Publisher Arthur Sulzberger Thursday called Carr "one of the most gifted journalists who has ever worked at The New York Times." Sulzberger added that "he combined formidable talent as a reporter with acute judgement to become an indispensable guide to modern media."
Reaction to Carr's death was a mix of disbelief and shock among co-workers and fans.
Earlier in the evening, Carr appeared at a New School and Times event in conversation with Edward Snowden, Glenn Greenwald, and Laura Poitras.
Information on what caused his death was not immediately available.
Carr was known for his columns on the media, as well as his candid 2008 memoir, The Night of the Gun.
He joined the Times in 2002, following work for the Washington City Paper and The Twin Cities Reader, according to the Times. He is survived by his wife, Jill Rooney Carr, and three daughters.
