Delia Ann Derbyshire (5 May 1937 – 3 July 2001) was an English musician and composer of electronic music. She carried out notable work with the BBC Radiophonic Workshop during the 1960s, including her electronic arrangement of the theme music to the British science-fiction television series Doctor Who. She has been referred to as "the unsung heroine of British electronic music", having influenced musicians including Aphex Twin, the Chemical Brothers and Paul Hartnoll of Orbital. After Derbyshire's death, 267 reel-to-reel tapes and a box of a thousand papers were found in her attic. These were entrusted to the composer Mark Ayres, who had salvaged the tape archive of the Radiophonic Workshop, and in 2007 were given on permanent loan to the University of Manchester for preservation. The tapes consist primarily of material from Derbyshire's freelance projects (e.g. works for theatre productions, films and festivals), some of her BBC work (the majority of Derbyshire's BBC work, including the original version of the Doctor Who theme, is housed in the BBC Archive Centre at Perivale), off-air recordings of interviews with Derbyshire and recordings of music by other composers and musicians, including Karlheinz Stockhausen, Krzysztof Penderecki and Can. Almost all the tapes were digitised in 2007 by Louis Niebur and David Butler, but none of the music has been published owing to copyright complications. In 2010, the university acquired Derbyshire's childhood collection of papers and artefacts from Andi Wolf. Subsequent donations to the archive have included items and recordings from Brian Hodgson, Madelon Hooykaas, Jo Hutton and Elisabeth Kozmian. These collections of material, including Derbyshire's working papers and digitised transfers of the tapes, are accessible at the John Rylands Library in Manchester. Material from the archive was used in the Radiophonic Workshop's score for the 2018 film Possum and provided a source of inspiration for Cosey Fanni Tutti in her soundtrack to the film Delia Derbyshire: The Myths And The Legendary Tapes (2020).
