The actor died of heart failure at his Malibu home, according to family spokesperson Jeff Ballard.

'He lived a wonderfully long life and while the family is saddened by his passing, he will live forever in their hearts,' Ballard said.

After a brief career in film, Conrad was put under contract by Warner Bros. Television, and most of his most popular work was for the small screen.

His first major success was on the detective series Hawaiian Eye, on which he starred as the half-Hawaiian private investigator Tom Lopaka.
