Dick Mills (born 1936) is a British sound engineer who worked at the BBC Radiophonic Workshop and provided special sounds for Doctor Who from 1973 to 1989. He is responsible for the frequently-used Cloister Bell sound. Back in 1963 he also helped Delia Derbyshire assemble the many different cues and individual notes of the Doctor Who theme. In more recent years he has joined up with Mark Ayres, Peter Howell, Roger Limb and Paddy Kingsland to form a band called The Radiophonic Workshop. They have toured and appeared at many festivals and concerts around the UK playing some of their most well known pieces from Doctor Who on some of the original instruments and machines used to create them.
