David Carr, the longtime Media Equation columnist for the New York Times, died Thursday, the Times reports. He was 58.

Carr, a distinguished journalist known for his popular coverage of the media business, died at St. Luke’s-Roosevelt Hospital after suddenly collapsing at the office, the Times says. He had appeared at the New School in Manhattan earlier on Thursday for a TimesTalks event.

"David Carr was one of the most gifted journalists who has ever worked at The New York Times," said Times publisher Arthur Ochs Sulzberger Jr, according to The New York Times .

In a memo to staff, Times' executive editor Dean Baquet called Carr "our biggest champion, and his unending passion for journalism and for truth will be missed by his family at the Times, by his readers around the world and by people who love journalism," the Times reported.

Carr's career spanned Minneapolis, Washington, D.C. and New York, where he wrote for The Atlantic Monthly, New York magazine and Inside.com before joining the Times in 2002.

He published a memoir in 2008 called "The Night of the Gun," detailing his recovery from drug addiction. But instead of writing a straight memoir about addiction, Carr conducted over 60 interviews as he examined the nature of memory.

He lived in Montclair, N.J. He is survived by his wife, Jill, and his three daughters.
