Legendary 60 Minutes personality Andy Rooney died Friday night.

The veteran newsman was hospitalized October 25 after suffering complications following surgery, just three weeks after he delivered his 1097th and final weekly segment on the CBS stalwart to cap off a 33-year run.

On October 2, the three-time Emmy-winner said in his final edition of A Few Minutes with Andy Rooney, "This is a moment I've dreaded ... I wish I could do this forever, but I can't, though ... but I'm not retiring. Writers don't retire, and I'll always be a writer."

In the segment, Rooney admitted he probably hadn't "said anything here that you didn't already know or have already thought ... that's what a writer does ... a writer's job is to tell the truth.

Rooney -- who began his regular on-air role with the show in July 1978 -- admitted one aspect of being on TV he didn't care for was being famous.

"I spent my first 50 years trying to become well-known as a writer, and the next 30 trying to avoid being famous," he said. "I walk down the street now or go to a football game and people shout, 'Hey, Andy!' And I hate that. I don't say this often, but thank you -- and if you do see me in a restaurant, please, just let me eat my dinner."

Rooney's writing exploits included four books about World War II; a stint at the military newspaper Stars and Stripes; and positions writing for entertainers Arthur Godfrey and Garry Moore.

The broadcasting legend is survived by four children. His wife Marguerite died of heart failure in 2004; the two were married 62 years.

Rooney died in a New York City hospital. He was 92.

"This is a moment I've dreaded," Rooney, a three-time Emmy-winner, said in his 1097th essay. "I wish I could do this forever, but I can't, though ... but I'm not retiring. Writers don't retire, and I'll always be a writer."

Broadcasting legend Andy Rooney delivered an emotional editorial on 60 Minutes Sunday, marking his final regular appearance after 33 years on the CBS stalwart.

"This is a moment I've dreaded," the 92-year-old newsman said in his 1097th essay. "I wish I could do this forever, but I can't, though ... but I'm not retiring. Writers don't retire, and I'll always be a writer."

Rooney admitted he probably hadn't "said anything here that you didn't already know or have already thought ... that's what a writer does.

“A writer's job is to tell the truth,” Rooney said. “I know I've been terribly wrong sometimes, but I think I've been right more than I've been wrong."

Broadcasting legend Andy Rooney is slated to make his final regular appearance on 60 Minutes after 33 years on the CBS stalwart, as the 92-year-old newsman will make the announcement while reading his customary essay Sunday -- his 1097th, overall.

Rooney began his regular on-air role with 60 Minutes in July 1978 with his weekly feature titled A Few Minutes With Andy Rooney. Then, he discussed how Independence Day weekend, despite the reporting at the time, was one of the safest times of the year to be on the road.

CBS News chairman and 60 Minutes executive producer Jeff Fager said, "There's nobody like Andy and there never will be. He'll hate hearing this, but he's an American original. His contributions to 60 Minutes are immeasurable.

"He's also a great friend,” Fager said. “It's harder for him to do it every week, but he will always have the ability to speak his mind on 60 Minutes when the urge hits him."
