Delia Derbyshire was born in 1937 and joined the BBC Radiophonic Workshop in 1960. She was the first qualified musician there (she had a degree in Mathematics and Music; earlier employees were oriented towards sound effects for radio drama). Although marginalized and uncredited during the time she worked there, Delia has retrospectively been hailed as a pioneer of electronic music. She is best known for creating the theme tune for Doctor Who, based on a rough compositional idea by Ron Grainer. Other well-known works include "Blue Veils, Golden Sands" and "the Delian Mode".
