David Paul Greenfield (29 March 1949 – 3 May 2020)[1][2] was an English keyboardist, singer and songwriter who was a member of rock band the Stranglers.

[8] He joined the Stranglers after answering an advert by the band in Melody Maker in July 1975,[9] replacing Hans Wärmling,[10] playing his first gig with them on August 24, 1975.

[4] He was a musical perfectionist and could be awkward in social situations; observations consistent with his diagnosis, never made public during his lifetime, of what Burnel inaccurately described as a "very high-functioning autistic".

Greenfield's sound and style of playing, particularly on the Stranglers' debut album Rattus Norvegicus, has been compared to that of Ray Manzarek of the Doors.

[17] His distinctive sound on the early Stranglers recordings involved the use of Hohner Cembalet (model N), Hammond L-100 electric organ, a Minimoog synthesizer, and later an Oberheim OB-Xa.

[16] Notable instances of this include in "Genetix" when it accompanies his own vocal and during the "Gene Regulation" section underneath Hugh Cornwell's monologue,[22] and on "Baroque Bordello" towards the end of the song.
