Adam Rich, child star on "Eight Is Enough," dies at age 54

Adam Rich, the child actor with a pageboy mop-top who charmed TV audiences as "America's little brother" on "Eight is Enough," has died, his publicist said in a statement Sunday. He was 54.

Rich died Saturday at his home in the Brentwood section of Los Angeles, said Lt. Aimee Earl of the Los Angeles County Medical-Examiner Coroner's office. The cause of death was under investigation but was not considered to be suspicious.

Rich had a limited acting career after starring at age 8 as Nicholas Bradford, the youngest of eight children, on the ABC hit dramedy that ran from 1977 to 1981.

He had several run-ins with police related to drugs and alcohol — and sought treatment at the Betty Ford Center in Rancho Mirage.

Rich suffered from a type of depression that defied treatment and he had tried to erase the stigma of talking about mental illness, said publicist Danny Deraney. He unsuccessfully tried experimental cures over the years.

Deraney said he and others close to Rich were worried in recent weeks when they couldn't reach him.

"He was just a very kind, generous, loving soul," Deraney said in a statement. "Being a famous actor is not necessarily what he wanted to be. ... He had no ego, not an ounce of it."

Deraney also shared memories of Rich on Twitter, writing "Adam and I would chat on the phone talking baseball. We both loved the Yankees, but he loved the Dodgers a smidgen more ... Something you did not know...He was in NYC in Dec 1980 and met John Lennon the day John died."

Rich discussed his mental health on Twitter and noted in October that he'd been sober for seven years. He said he wasn't perfect — referring to arrests, many stints in rehab, several overdoses and "countless detoxes (and) relapses" — and urged his nearly 19,000 followers to never give up.

"Human beings weren't built to endure mental illness," Rich tweeted in September. "The mere fact that some people consider those to be weak, or have a lack of will is totally laughable … because it's the total opposite! It's takes a very, very strong person … a warrior if you will … to battle such illnesses."

Rich posted a picture of himself from his heyday with one-time child star Mickey Rooney.

"Everyone used to say to me, 'You are the modern day Mickey Rooney,'" he tweeted. "But when Mickey Rooney told me that himself, it meant a helluva a lot more to me!"

Nearly 27 years ago, Rich participated in a hoax that Might magazine published about the actor getting killed in a robbery outside a Los Angeles nightclub in 1996. The article in the little-known magazine was intended as a satire of America's celebrity obsession but fizzled when the spoof was revealed.

"I think we were a little too subtle. People were not getting the joke," Rich later told the Chicago Tribune. "I don't want to be dead."

Rich was the little brother to a generation of TV viewers as the mop-top son of a newspaper columnist played by Dick Van Patten, who has to raise eight children alone after his wife in the show — and the actress who played her — died during filming of the first season.

Rich starred in the series "Code Red" from 1981-82 and voiced the character of Presto the Magician on "Dungeons & Dragons" from 1983-85, according to the IMDB.com. He reprised his best-known role in two "Eight is Enough" TV movie reunions.

But the balance of his acting career was in single-episode appearances on some of the most popular TV shows of the time: "The Love Boat," "The Six Million Dollar Man," "Silver Spoons," and "Baywatch." His most recent credit listed on IMDB was playing Crocodile Dundee on "Reel Comedy" in 2003.
