Delia Derbyshire - Electronic Pioneer

Born in Coventry in 1937, Delia Derbyshire became one of the 20th Century's most influential electronic composers and musicians. She worked for many years at the BBC Radiophonic workshop, creating new sounds and themes. She is also famous for arranging the score for the unmistakable Dr Who theme and is still name-checked and covered by modern electronic artists such as Aphex Twin and The Chemical Brothers.

This is from an article on the BBC website about an archive of newly found recordings.

"A hidden hoard of recordings made by the electronic music pioneer behind the Doctor Who theme has been revealed - including a dance track 20 years ahead of its time.

Delia Derbyshire was working in the BBC's Radiophonic Workshop in 1963 when she was given the score for a theme tune to a new science fiction series.
She turned those dots on a page into the swirling, shimmering Doctor Who title music - although it is the score's author, Ron Grainer, who is credited as the composer.

Now David Butler, of Manchester University's School of Arts, Histories and Cultures has revealed for the first time the existence of 267 tapes found in Ms Derbyshire's attic when she died in 2001.

They were, until last March, in the safekeeping of Mark Ayres, archivist for the Radiophonic Workshop - and have lain unheard for more than 30 years.

Amongst the recordings is some ethereal whooshing from a 1969 production of Hamlet at the Roundhouse in London; an extraordinary kit of parts for one of her most-admired pieces; and the theme for a documentary set in the Sahara which shows how she used her voice as an instrument."
