Sylvia Anderson, best known as the voice of Lady Penelope in the TV show Thunderbirds, has died after a short illness, her family has confirmed.
Anderson co-created the hit science-fiction puppet series, which ran from 1965, with her late husband Gerry.
In a career spanning five decades, she also worked on shows Joe 90 and Captain Scarlet, and for US TV network HBO.
She died at her Buckinghamshire home. Her daughter said she was "a mother and a legend", who would be sadly missed.
"Her intelligence was phenomenal but her creativity and tenacity unchallenged. She was a force in every way," Dee Anderson said.
