Delia Derbyshire was a pioneer of electronic music who arranged the iconic Doctor Who theme tune in 1963. She was a talented composer and sound designer who worked at the BBC Radiophonic Workshop for over a decade, creating music and sound effects for radio and television programmes. She used tape machines, oscillators, filters and other devices to manipulate sounds and create new sonic textures. She was ahead of her time and influenced many musicians who came after her.

I learned about her work when I researched the history of electronic music. Today I found this video on the BBC website while searching for another topic and got sidetracked again.
