After The Brady Bunch ended, Henderson reprised her role as Carol in various spin-offs, and also made appearances in TV shows including Roseanne and Murder, She Wrote.
A game-show enthusiast, Henderson appeared on celebrity editions of Who Wants to Be a Millionaire, Family Feud, and The Price is Right over the years. She also competed on Dancing with the Stars in 2010.
The business-savvy starlet didn't rely on acting alone to boost her coffers. She was the spokeswoman for Wesson cooking oil for over 20 years, and was paid to promote brands such as Polident and Pepsi.
Henderson never lost the acting bug, and her final movie was 2017 comedy flick Bad Grandmas; the film was released posthumously as Henderson passed away in 2016 aged 82. At the time of her death, Henderson was estimated to be worth an impressive $10 million (£9.2m).
