One of television’s most beloved actors died on Wednesday. Don Grady, known as the big brother Robbie Doulgas on the 1960 hit My Three Sons, was 68 years old.
His My Three Sons co-star Barry Livingston confirmed Grady’s death late Wednesday to The Associated Press.
Grady reportedly suffered from cancer and received hospice care at his home in Thousand Oaks, California. The exact cause of death is unknown.
“It’s the oldest cliche in the world when TV brothers refer to each other like biological brothers, but he was the oldest, and somebody I looked up to and learned from a great deal about life,” Livingston said of his late co-star.
Grady was born in San Diego as Don Louis Agrati. He kicked off his career singing and dancing on The Mickey Mouse Club, but became popular when he played one of Fred MacMurray’s three sons on the ABC series.
The popular show was among the longest running sitcoms of all time with 380 episodes.
