Though electronic composer Delia Derbyshire has been referred to as "the unsung heroine of British electronic music," it wouldn't be a stretch to expand upon the accolade and call her an unsung heroine of music, period -- regardless of nationality, regardless of field. The leading light of the BBC's Radiophonic Workshop throughout the '60s and the first half of the '70s, Derbyshire's most notorious work is the instantly recognizable theme for the infamous science fiction program Dr. Who. But Derbyshire was no mere flash in the pan. She was a great talent and a great mind, and she should be regarded with the likes of Karlheinz Stockhausen and Raymond Scott as one of the key figures to push electronic music forward. Just as important, Derbyshire wasn't secretive with her knowledge and found it necessary to pass it around freely.
