<p>Sylvia Anderson (née Thamm), born 25 March 1937 (1937-03-25) (age 73), is a British voice artist and film producer, most notable for collaborations with Gerry Anderson, to whom she was married from 1962 to 1975.
Though co-creator and co-writer of some of their productions through the 1960s, Sylvia's main contribution was the development of realistic characters that viewers could identify with 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 television series and subsequent films. She and Gerry Anderson married in 1960 and were divorced in 1980 following a 5-year separation.
Following graduation from the London School of Economics, Sylvia Thamm joined Polytechnic Films as a secretary, where she met editor/director Gerry Anderson. When Anderson and his colleague Arthur Provis created AP Films following the collapse of Polytechnic in 1957, Sylvia joined them along with colleagues John Read and Reg Hill. She became Anderson's second wife shortly after, in 1960, and became more involved in production duties.
