Born in Liverpool in 1938,[1] Hodgson joined the BBC Radiophonic Workshop in 1962 where he became the original sound effects creator for the science fiction programme Doctor Who.
Earlier, in 1966, with fellow workshop musician Delia Derbyshire and EMS founder Peter Zinovieff, he helped set up Unit Delta Plus, an organisation which they intended to use to create and promote electronic music.
Many of these recordings, including compositions by Hodgson using the name "Nikki St George", were later used on the seventies ITV science fiction rivals to Doctor Who; The Tomorrow People and Timeslip.
Hodgson withdrawing his BBC pension of around "two thousand pound"[3] set up the studio with Delia Derbyshire, who contributed a single tape recorder.
Their versions of Tchaikovsky's None But the Weary Heart and Debussy's "La fille aux cheveux de lin" later appeared in the Doctor Who serial "The Robots of Death".
