The Chronology page collects anything about Delia with a date, in order.
“Radio had a very big influence over me. It was so important during the Second World War. Life was really very basic at that time and radio provided an essential escape and a greatly valued education.”
17th January 1939: Delia's sister, Catherine, is born.
14 November 1940: Coventry's largest and most destructive bombing raid starts in the evening.
After the worst blitz I was shifted to Preston, where my parents came from. It's only today that I've realised that the sound of clogs on cobbles must have been such a big influence on me - that percussive sound of all the mill workers going to work at six o'clock in the morning.
8th/9th and 10th/11th April 1941: Coventry's second major air raid takes place on two nights apart.
3rd August 1942: The final air raid falls on Coventry.
1948: Delia starts at Barrs Hill School.
“At school I wasn't allowed to study music. I studied mathematics, theoretical mechanics and physics. The most exciting part of physics was acoustics, although unfortunately my teacher didn't share my enthusiasm! So I was forced to teach myself. I learnt about acoustics and indulged my passion for music away from school.”
1950: "At the age of thirteen she was an accomplished pianist, and played our piano faultlessly in spite of my picking out all the complicated bits I could find on the sheet music available."
6th March 1951: Delia takes a music test and scores 50/50.
8th May 1953: Delia writes the English essay Wireless Programmes, deploring the dumbing down of BBC programmes caused by them moving away from music and towards variety.
1953-54: Delia wins many piano competitions.
1956: Delia leaves Barrs Hill School and goes to to Girton College, Cambridge.
“I won a scholarship to Cambridge reading mathematics. That was a strange year, one third of my fellow students gave the course up and so I was given the opportunity of changing to another subject. Well I wanted to do music; to me that was a forbidden paradise. They eventually realised that I had a natural instinct for music and allowed me to enter the course.”
1957: Delia switches her degree from Mathematics to Music.
“There were only a few women at the University at that time and so we were treated terribly. But I had the solace of my music. The musicians hated acoustics and the theory of sound, but when we studied that I was in my element. I found myself drifting away from the syllabus to learn about mediaeval and modern music. That didn't go down too well with my tutors. They wanted me to study the period 1650 to 1900, but it bored me. So I didn't do too well there!”
1959: Delia graduates with an MA in Mathematics Part 1 and Music Part 1. "She was a really nice girl, but changed after she went to Cambridge." "We were two different people inhabiting different planets, and a wide gulf had grown between us."
“After my degree I went to the careers office. I said I was interested in sound, music and acoustics, to which they recommended a career in either deaf aids or depth sounding. So I applied for a job at Decca Records. The boss was at Lords watching cricket the day I had my appointment, but his deputy told me they didn't employ women in the recording studio.”
“[After I graduated, I] went straight abroad with the Pembroke University Players doing sound effects for Julius Caesar. I had such fun, I just didn't want to come back to England!”
June-September 1959: Delia starts working as a tutor in music and mathematics in Geneva for the British Consul-General and others.
September-December 1959: Delia starts working at the International Telecommunications Union, United Nations, Geneva, as Assistant to Gerald G. Gross, the Head of Plenipotentiary and General Administrative Radio Conferences, where she works for two years, all the time bombarding the B.B.C. with applications for a job. [this "two years" conflicts with Clive Blackburn's biography].
January-April 1960: Delia returns to Coventry and starts teaching general subjects in a primary school.
May-October 1960: Delia works at Boosey & Hawkes music publishers, London as Assistant in the Promotion Dept dealing with advertising and publicity material.
November 1960: Delia joins the BBC as a Programme Operations Assistant.
“There was a programme called Record Review, and they just played tiny extracts from records. And one of the music critics would say, “Look, it's on this side of the LP. I don't know where it is, but it's where the trombones come in.” And I'd just hold it up to the light and see the trombones and put the needle down exactly where it was. And they thought it was magic.”
In 1961, Delia becomes a Studio Manager at the BBC.
“Eventually the BBC wrote to me and I went along for an interview. I impressed the interviewers and eventually became a studio manager.”
“It was very exciting, especially on the music shows. All the records had to be spun in by hand and split second timing was essential. When tapes came in I used to mark them with yellow markers to ensure that one followed another and that there were no embarrassing gaps in between.”
In 1961 or 1962, Delia takes up the double bass and takes lessons in Covent Garden once a week.
In 1962, Delia creates Arabic Science and Industry, Science Serves the Arts, Time On Our Hands, musical effects for Closed Planet, and probably Mattachin. By a strange quirk of copyright law regarding recordings made before 1963, these are now in the public domain.
“I'd heard about the Radiophonic workshop and I said "Oh, I want to go there" but I was so keen! I went there on my days off, just observing, so that's where I learned about tape manipulation.”
2nd April 1962: Enid Law, Membership Officer of the British Film Institute, replies to Delia's letter of the 23rd, returning her membership card endorsed for free associate membership.
April 1962: Delia starts a three-month attachment to the BBC Radiophonic Workshop, which is to last 11 years.
“I was really happy as a studio manager until I realised that I could move to the Workshop and before I had even finished asking my boss for a transfer, he had his hand on the telephone. It turned out that I was the first person who had actually asked to go there. Previously people had been sent, usually unwillingly, for a six month attachment. I was allowed to stay longer and became the most junior person there, even though I was the most highly qualified.
I joined in 1962 and the first thing that I did was to go off and tour around our European colleagues' studios like the ORTF [Office de Radiodiffusion Télévision Française at Radio France] to see how they worked. I was so brave - just marching in like that!
It wasn't long until I returned and began work on Doctor Who. I had only done one other television programme before that called Time On Our Hands, using beautiful abstract electronic sounds.”
When she first came to the Workshop she rummaged along the bookshelves and said "Ooh! You've got this book!" and this book had a lot of tables in about frequencies. Anyway, she went through this book and she found masses of faults, of mistakes in the tables so she sat down and corrected all of those before she started.
“The Doctor Who music was the only time in my whole career that I realised someone else's score for television. Thereafter I did my own scores for hundreds of television and radio programmes.”

“something serious happened around '72, '73, '74. The world went out of tune with itself and the BBC went out of tune with itself.”
“I still haven't worked out why I left - self preservation, I think.”
“I eventually left [because] I didn't want to compromise my integrity any further. I was fed up having my stuff turned down [by the BBC] because it was too sophisticated, and yet it was lapped up when I played it to anyone outside the BBC. The BBC was very wary, increasingly being run by committees and accountants, and they seemed to be dead scared of anything that was a bit unusual.”
From this moment on, at least until 1995, "nobody spoke of Derbyshire at the Radiophonic workshop. She was never mentioned."
Delia and Brian Hodgson both leave the BBC to set up their own musical studio Electrophon. but she soon quits and moves to Cumbria to work as a radio operator during the laying of a gas pipeline, then working and living with Li Yuan-chia at his Cumbrian home and art gallery, and living a private life.
“The idea was that we were going to leave together and set up Electrophon,... she started dragging her heels about leaving. I left [and] blew my pension on setting up Electrophon. And Delia was supposed to come with me... we did “the Legend of Hell House” together, but she was not mentally there much. She'd get enthusiastic for a minute or two and then lose interest. So that was a difficult time. At that point, Delia almost “disappeared”. That then led on to her leaving London and going up north to work on the pipeline”
She applied for the job at Laings “as soon as she saw the word ‘radio’ [in the advertisement]”.
“I was the best radio operator Laing Pipelines ever had! I answered a job in the paper for a French speaking radio operator. I just had to sleep - everything was out of tune, so I went to the north of Cumbria. It was twelve miles south of the border. I had a lovely house built from stones from Hadrian's Wall. I was in charge of three transmitters in a disused quarry [delivering the weather forecast in French every night]. I did not want to get involved in a big organisation again. I'd fled the BBC and I thought - oh, Laing's... a local family firm! Then I found this huge consortium between Laing's and these two French companies.”
She told me she did it to make her socially acceptable. The women were wary of her on her own and she wanted to join the darts team. 'To her, it was a marriage of convenience. She thought it would be a friendship but they quickly discovered they weren't compatible and had a huge row. That was the end of that but she never divorced him.
In 1976, Delia stops working for Laing as a Radio Operator on the laying of a gas pipeline between Scotland and Cumbria.
When she left the BBC, she makes her way north up to the borders of Scotland and England and she settles in the village of Gilsland.
1st March 1976: Glynis Jones of the BBC writes to Delia about renaming five of her tracks, originally for Travelling in Winter, The Bagman and The Naked Sun, for their inclusion on a library record of sound effects Out Of This World.
[After the problematic marriage to Hunter] she moved several miles away from Gilton to the hamlet of Banks and lived at the LYC. She's there across 1976-1977 and she has to manage the place.
In 1977, Delia co-signs with Li Yuan-chia a copy of his Artist Book No.4.

15 September 1998: Delia's husband, David William Hunter, dies in Haltwhistle, Northumberland.
“She really enjoyed herself although... she was very nervous and very tearful,... slightly fragile” “...when she got attention at the “Dr. Who” convention, she enjoyed it, after years of neglect”
In 2000 and 2001 she works with Sonic Boom as advisor/co-producer on the EAR LPs Vibrations and Continuum by long nightly phone calls 5 nights a week and visits to Rugby every Weds or Thurs on her 'private train', having realised that some trains went from Rugby to Northampton which were just returning and not scheduled.

- Comment by user Tagginglaong on 19 Jul 2008: "I worked at Laing Pipelines during 1976 on the radio communications. What has this to do with Delia? Well she had been the previous incumbent of the job and I have to tell you she was mightily respected by all the engineers and crew from Scotland to Cumbria, both French and English. Everyone knew her as the woman who had been in the Radiophonic Workshop and most said she had written the Dr Who theme. I was told she took the job with Laings because she wanted a little space in her life. I can't vouch for her reasons, but I can vouch for how much her workmates thought of her. I'm sorry I never met her, but apparently she was pretty formidable."
