The Washington-born actress is now 86 years old and most recently had a guest role in long-running soap opera “The Young and the Restless”.

As elder daughter Betty ‘Princess’ Anderson on “Father Knows Best”, Elinor was a central character to the show which portrayed a middle-class family living an idyllic all-American life in the Midwest.

The show started on the radio in 1949 and aired every Thursday until 1954. It was then picked up by CBS for television keeping only actor Robert Young from the radio show who played dad Jim Anderson.

During her six years with the hit show, which at its height was in the top ten most watched American TV shows, Elinor also appeared in “Crossroads” and in the “George Burns and Gracie Allen Show.”

Her schedule was hectic and she once admitted that she didn’t have time to watch the show back.

“By the time we’d get home at night and have our dinner, we’d be getting ready to learn our lines, go to sleep to get up and do it again. So, I never saw the show,” she told Closer.

Born in Tacoma in 1937 she eventually became the main breadwinner of the household when her career took off in her teenage years appearing in movies Love is Better than Ever, starring Elizabeth Taylor and Girls Town.

As Elinor was still a child and living in California she had to have an adult on set with her at all times so because her father was out of the picture and her mom worked full-time her mom Doris gave up her job.

After “Father Knows Best” ended Elinor went on to appear in “The Andy Griffith Show”, “Dr Kildare”, “Star Trek” and “Mork & Mindy.”

In all the 86-year-old screen legend has appeared in more than 70 TV shows as well as movies such as Winter Wonderland and Pretty Woman.

Elinor married her first husband when she was 19 years old and admitted that she hoped if she got married and had a baby she would become a grown up.“I had just turned 19 and I was like a 13-year-old 19,” she told Emmy TV Legends.

“I’d never had a chance to grow into a real person so I was not mature at all. I’d had no high school friends…I had this idea if I ran away and got married and had a baby I’d be a grown up.”

So she decided the next person who asked she would agree to, this man turned out to be sound man on “Father Knows Best” Richard Smith.
