Elinor Donahue – 84 Years
Although she is best known for portraying Betty Anderson, the daughter of Jim and Margaret Anderson in the ’50s CBS sitcom ‘Father Knows Best,’ Elinor Donahue started acting when she was only five years old! That explains her incredibly natural-looking appearance on-screen, doesn’t it?. The star had four guest roles on ‘The Young and the Restless,’ in 2010, before making a graceful exit from the industry. The final scenes in the series took place in front of a house that was a clone of the Anderson home in the 50s show! That was just a wonderful tribute to her breakthrough role and fans of the show as well!
