"He was an incredibly kind and wonderful father," Osmond's son Eric said in a statement obtained by Fox News on Monday. "He had his family gathered around him when he passed. He was loved and will be very missed."
Osmond died at his Los Angeles home on Monday, according to Variety. No other details about his death are currently known.
The Glendale, Calif., native started his career at age 4, working in commercials and as a film extra, and at age 9, he got his first speaking role in the movie "So Big," Variety reported. He went on to appear in "Good Morning Miss Dove," "Everything But the Truth," "The Loretta Young Show," "The Walter Winchell File," "Fury," "Lassie," and "Wagon Train," among others.
The actor starred in "Leave It to Beaver" from 1957 to 1963. Osmond's part as the two-faced teenage scoundrel, Haskell, was only supposed to be a one-off guest appearance, however, he did so well in his portrayal -- and the show's producers and its audience found him so memorable -- that he became a regular, appearing in nearly 100 of the show's 234 episodes.
