Jimmy's parents were zoologists who made a special study of primates. They died whilst on safari in Kenya. The responsibility for bringing up Jimmy fell to his older brother Bill who is 12 years older.
Naturally he found it hard, trying to raise a very inquisitive child (then 6 years old) and a mischievous monkey. When Jimmy was away at school, Bill was able to build up his transport business and during the holidays he used to take Jimmy and Mitch with him on his journeys. This also helped Jimmy's education. It was on one of those trips that their plane crashed in the sea only to be rescued by Mike Mercury in Supercar.
Seeing Jimmy as a younger version of himself Mike discussed his ideas with Beaker, Popkiss and Bill. They would look after Jimmy, enabling Bill to carry on with his business without worrying about his younger brother.
Everyone agreed and Jimmy was overjoyed to stay at Black Rock with his newfound friends. Apart from helping where he can around the labs, Jimmy, like Mike, loves aircraft and builds models. He also tries to teach Mitch new tricks.
Sylvia Anderson (née Thamm, born 25 March 1927) is a British television and film producer and voice actress, most notable for collaborations with Gerry Anderson, (in casu Thunderbirds and the subsequent films Thunderbirds Are GO! (1966) and Thunderbird 6 (1968)) to whom she was married from 1960 to 1981.
Although co-creator and co-writer of some of their TV productions during the 1960s, Sylvia's main contribution was the development of realistic characters that viewers could identify and become involved with. She usually directed the bi-weekly voice recording sessions, and provided the voices of many female characters, most memorably Lady Penelope in the Thunderbirds TV series and subsequent films. She and Anderson married in 1960 and divorced at the start of the 1980s following a five-year separation.
