The Los Angeles County Medical Examiner reported that Adam Rich, best remembered for his portrayal of Nicholas Bradford in the 1970s television drama "Eight is Enough," passed away on Saturday at the age of 54.
Rich's family confirmed to TMZ that the actor passed away in his Los Angeles home, where, according to police authorities, the former child star was discovered dead by an unknown person who had been to the house, according to the Daily Wire.
The official cause of death has not been disclosed, but there is no suspicion of foul play, according to the authorities.
NBC News said. Danny Deraney, Rich's spokesperson, called the actor a "wonderful guy" and "really America's little brother."
“He was kind, generous and a warrior in the fight against mental illness,” Deraney said. “He was so unselfish and always looked out for those he cared about. Which is why many people who grew up with him feel really sad today.”
Rich became well-known in the 1970s while playing Nicholas, the youngest son, on the ABC television series "Eight is Enough," which lasted from 1977 to 1981.
Rich was the reason "why the show was a big success," according to Dick Van Patten, who co-starred in the TV drama as Rich's father during an interview in 2011.
“People loved him!” Van Patten said, according to Page Six. “[Fans] named a child Nicholas and everything because of him. He was cute, and he was a good actor. He was very natural.”
In the late 1970s and early 1980s, Rich would go on to play smaller parts in a variety of films and television programs, including "Fantasy Island," "CHiPs," and "Small Wonder." He also received credit as a voice actor on the animated series "Dungeons & Dragons."
Rich's final appearance on TV or in the public eye occurred in a 1993 episode of "Baywatch" before a ten-year absence.
In the 2003 David Spade comedy "Dickie Roberts: Former Child Star," he made a comeback to play himself. He played Crocodile Dundee in the television series "Reel Comedy" that same year.
Rich allegedly battled substance problems, which led to an arrest in 1991 for breaking a drugstore window to get drugs, according to TMZ. Later, Van Patten helped him out.
Rich frequented rehab throughout the ensuing years, according to Page Six. After almost colliding with a California Highway Patrol vehicle, authorities again detained Rich in 2002 on suspicion of DUI.
Rich told CBS News reporters, "I've been sober for ten years," in response to the accusations.
