Ms Anderson co-created the popular puppet series with her husband Gerry. As well as being the voice of Lady Penelope she also co-wrote some of the episodes for the series and helped with costume design and character development.

Speaking last September about an ITV reboot called Thunderbirds Are Go!, Ms Anderson said she was excited to voice the part of the great aunt to her original character.

Ms Anderson was born in London and graduated with a Degree in Sociology and Political Science at the London School of Economics.

She moved to the US and worked as a freelance journalist. She met her husband Gerry while working for a film company and together they came up with the idea for Thunderbirds which ran from 1965.

Lady Penelope was modelled on Ms Anderson and she provided the puppet's distinctive voice.

The popular science-fiction series, which also led to two feature-length films and a toy franchise, celebrated its 50th anniversary last year.

Ms Anderson was also a successful author and was head of programming for HBO in the UK.

She had one daughter and a son as well as four grandchildren and a great-granddaughter.
