The papers were received from Mrs. Young through the agency of Mr. S.T. Lunt, who provided valuable help and advice in the initial sorting of the papers. We are also grateful to Dr. A. Spinks, F.R.S. who kindly allowed us to see and to quote from a proof copy of the Memoir of C.A.J. Young by R.L. Day and A. Spinks to be published in Biographical Memoirs of Fellows of the Royal Society, 25, 1979.

Administrative history:
C.A.J. Young joined I.C.I. in 1940 and worked on various engineering projects during the war, including FIDO (for dispersing fog from airfields) and the Tube Alloys (Atomic Bomb) Project. Some reminiscences about this period are the be found in CSAC 70.8.79.C.13, CSAC 70.8.79.C.14. In 1946 the I.C.I. Technical Director, F.E. Smith (later Sir Ewart Smith) invited Young to set up a central instrument laboratory. Young later wrote of this invitation 'I was very fortunate in 1946, in two respects. First, my experience had shown me the importance to industry of exploiting the full potential of instrumentation and automatic control, and l believed l knew how his could be achieved. Secondly, Sir Ewart Smith had also appreciated the need for long-term research and development and invited me to be responsible for fulfilling in for I.C.I.' (see CSAC 70.8.79.A.2)
The laboratory was originally set up as 'A general instrument research and development section... to act as a service to all Divisions... keep in touch with instrument practice at home and abroad, and hold certain specialised equipment for general use in I.C.I.' (see CSAC 70.8.79.B.3). In the early 1950s, however, Young decided to concentrate the work of the laboratory on the design of process control systems. His objective was that process, plant and control equipment should be designed as one unified system to eradicate the practice of adding the control equipment as an afterthought to a plant already designed. In order to achieve this he directed the laboratory towards the target of predicting the dynamic behaviour of chemical processes of the design stage, and introduced the concept of the 'mathematical model' to describe any system under consideration.
By 1956 electronic computers capable of solving the complex equations generated by this line of research were a practical reality, and Young was quick to see their advantage. He persuaded I.C.I. to purchase a Ferranti Mercury in 1958, and his subsequent efforts to ensure that the Company took advantage of the most recent developments in the computing industry are well documented in the collection (see CSAC 70.8.79.B.78 - CSAC 70.8.79.B.115). He also encouraged research into a new high level language specially designed for on-line computer applications, and a novel system of interface instrumentation, both of which were designed to reduce costs and thus improve the practical possibilities of implementing a complete on-line system (see CSAC 70.8.79.B.95 - CSAC 70.8.79.B.102).
Recognition of Young's achievements in the field of process control came in 1969 with the award of the honorary degree of Doctor of Technology by Bradford University (see CSAC 70.8.79.A.18) and the presentation of the first Sir Harold Hartley Medal by the Institute of Measurement and Control (formerly the Society of Instrumental Technology, of which Young was President, 1954 - 57). Fellowship of the Royal Society followed in 1972.
At the end of 1968 Young had to undergo a severe operation from which he never fully recovered. He continued to involve himself in the work of the laboratory when he was able, but in 1971 his health forced him to relinquish the Directorship and he accepted the advisory post of Technical Director to the I.C.I. Corporate Laboratory which was formed by merging the Central Instrument Research Laboratory at Bozedown with the I.C.I. Petrochemical and Polymer Laboratory at Runcorn in 1972. He retired from I.C.I. in 1973.
A word should be said here about Young's Christian names. He was born Alwyne Jack, and many of his friends and colleagues called him 'A.J.', but his wife knew him as Christopher, the name by which he had first introduced himself to her, and in 1969 he changed his name by deed poll to Christopher Alwyne Jack Young.

SECTION B CENTRAL INSTRUMENT RESEARCH LABORATORY, IMPERIAL CHEMICAL INDUSTRIES LTD. (I.C.I.)  CSAC 70.8.79/B.1 - B.210  [n.d.]

Administrative history:
The Central Instrument Research Laboratory went through several changes of name during Young's Directorship. It started life at The Frythe, Welwyn Garden City, when it was called the Central Instrument Section. It was moved to Bozedown House, near Reading, in 1956 and changed its name to the Central Instrument Laboratory, later becoming the Central Instrument Research Laboratory (CIRL), the name by which it was most commonly known. Several other names were suggested for it during the 1960s (see especially B.20) but it remained unchanged until the merger with the Petrochemical and Polymer Laboratory at Runcorn in 1972, after which it became known as the Corporate Laboratory.

Young's own description in CSAC 70.8.79.A.2 of the development of the work of the Laboratory to the mid-fifties runs as follows:
'We set out to design process control systems using the theory developed before and during World War II by the servo-mechanism people; e.g. for the control of antiaircraft guns. We found at once that the theory could not be applied quantitatively, because the dynamic characteristics of the process and plant to be controlled were not known. We set about determining these characteristics from theoretical and empirical considerations. We made equipment and developed techniques for comparing our predictions with the response of actual processes. After some substantial work on the physical (separation) processes, primarily distillation, with fair results in simple, cases, we decided to tackle the heart of the process, namely, the chemical reaction and the reactor.'

Analogue and digital computers.  CSAC 70.8.79/B.70-B.115  [n.d.]

Contents:
Young's account in CSAC 70.8.79.A.2 of the developments which led I.C.I. to purchase its first computer runs as follows:
'When we had established the mechanism of a physical or of a chemical process and could represent its behaviour (to a sufficiently close approximation for design purposes) by a set of mathematical equations (which came to be known as the "mathematical model" of the system), we were at once faced with the difficulty of using the result; which required solving the equations. It was clear that substantial progress could be made only by using the electronic computer: then a new tool. First we used the Ferranti MERCURY (Digital) computer at Manchester University and various analogue computers, as far afield as Bergen. We then set up an analogue computers at Bozedown... and a digital computer at Wilton Works... We provided a complete analogue and digital computing service for the whole of I.C.I.: with a mixed team of mathematicians, engineers and chemists to bring the facilities of this service to the notice of their divisional colleagues, and to assist them in using it. Another team was responsible for developing the service itself, particularly building up the library of programmes and developing the "software" generally.
The following papers documents many of these developments.

It was as a result of reading this paper, coupled with my own experience in the design of the Wilton Nylon plant, that I decided to investigate the role of computers for technical calculations in ICI.
This programme of work in turn led directly both to the purchase by ICI of a Ferranti Mercury digital computer for general purpose calculations and to the opening up of the field of work on chemical kinetics and their relation to process development in plant design.'

MEDIA and RTL projects.  CSAC 70.8.79/B.95-B.102  [n.d.]

Contents:
R.L. Day and A. Spinks in their Memoir of Young (Biographical Memoirs of Fellows of the Royal Society, 25, 1979) write:
'Later in the 1960s it became increasingly apparent that although the cost of the computer itself was decreasing at a rapid rate the cost of installing a total on-line computer system was not, and if anything was rising because of the increasing costs of software and the high cost of interface equipment to connect the computer to the process.
Christopher was also concerned by the fact that virtually all computer manufacturers were developing software and interface hardware that were largely incompatible, and by the resulting inefficient handover and rapid obsolescence of systems. This led him to create two new major research initiatives, one aimed at a special high level programming language designed for on-line (i.e. real time) applications RTL (Real Time Language), and the other aimed at a novel system of interface instrumentation MEDIA (Modular Electronic Digital Instrumentation Assemblies). Besides reducing the costs of implementing a complete on-line system both these initiatives shared a further objective, i.e. to be as far as possible "machine independent" and hence to be free from built-in obsolescence.'
The following papers relate to work on both these projects.

I.C.I. Instrument Information Bulletin, 1956-62  CSAC 70.8.79/B.177-B.210  [n.d.]

Contents:
This Bulletin was originally issued as an experiment of the request of the Instrument Research Panel. Its object was 'to record available information on:
a) Important papers, particularly if published in unfamiliar journals
b) I.C.I. reports; especially those originating outside instrument sections
c) Information on development work (projected, in hand, or complete) by instrument manufacturers, research associations or other external bodies; and
d) Information arising from proceedings at technical meetings or in committees, etc. and details of forthcoming events of special interest'.
The Bulletin was issued by the Central Instrument Section in monthly instalments designed for filing in ring binders with quarterly and annual indexes of contents, persons, subjects and companies. It was edited by various members of the Central Instrument Section in turn.
The final issue of the Bulletin was Vol.27, July 1962, its demise being attributed to 'current reorganisation of the activities in Head Office of the Central Instrument Section' (J.D. Tallantire, 8 August 1962. See B.209).
The contents of the binders are as received from the I.C.I. Corporate Laboratory.

Contents:
This Section contains a complete set of Young's publications up to 1969 as well as notes and drafts for unpublished material, mainly speeches. There is also a considerable amount of background material to a paper by Young on 'The Chemical and Petrochemical Industries' delivered at a Royal Society Discussion Meeting on 'Manufacturing Technology in the 1980's and subsequently published in Phil. Trans. R.Soc. Lond. A, 1973 (see CSAC 70.8.79.C.19 - CSAC 70.8.79.C.25).

Contents:
Set of publications, numbered 1-37, with an accompanying list. The set is missing nos. 5 (but see CSAC 70.8.79.C.2), 10, 15 and 24 (the last 3 are monographs), and was originally assembled in 1969 when Young was first proposed for Fellowship of the Royal Society (see CSAC 70.8.79.A.20).
This item includes publications only up to 1969.

[no title or date]  CSAC 70.8.79/C.2

Contents:
Typescript drafts of part of a report on a visit to the U.S.A. to study the state of instrumentation in the oil and chemical industries. They are undated except for a pencil annotation on the front of the first, 'late 53 or 54' (but see below).
Young was a member of the O.E.E.C. Mission sent to the U.S.A. in 1950 to study 'chemical apparatus' and was particularly responsible for the study of standardisation in chemical engineering practice, process instrumentation and same unit operations. The report on the Mission was published in 1952, and Young's contribution (chapters on 'Standardisation' and 'Instrumentation') appears as no.5 in his list of publications in CSAC 70/8/79/C.1, although it is missing from the accompanying set of papers.
It seems likely that these drafts were prepared for Young's contribution to the O.E.E.C. Report, particularly as mention is made of 'the Mission' in one of the drafts.

[no title or date]  CSAC 70.8.79/C.4

Contents:
'Progress in Process Instrumentation'.
Following an introductory article in February 1957, Young contributed a monthly article under this title, using the pen-name 'Regulus' to The Industrial Chemist.
The series began in May 1957, and was 'designed to give the industrial chemist, or engineer in the process industries, a guide to trends in current practice in instrumentation and application technique'.
The last article in the folder is dated April 1964.
In the account of his work which appears in A.2, while drawing attention to his most influential publications, Young wrote:
'Among these publications I count a monthly review, in the "Industrial Chemist", as one of the more important. These reviews were published under the pseudonym "Regulus"; so that I could write completely freely without committing the Laboratory or the Company, or embarrassing them with my personal views. This was a well-kept secret outside the Company; but I have found subsequently that my own colleagues recognised my style at the outset! I am grateful to them for not telling me (and others) at the time.
'Each of these monthly reviews commenced with a serious attempt to provide the reader with guidance on appropriate current problems and questions: they also urged industry from time-to-time to help itself by providing case histories of profitable applications of control.
'The reviews in the "Industrial Chemist" ran for seven years until Mr. Cecil King took over the journal and closed it down. This was a great loss to the process industries: the editor, Dr. G. Hoy Robertson had made the "Industrial Chemist" an excellent medium for most serious communication with people at all levels, and with all kinds of interests, in the Process Industry.
'The closure may have been economic for Mr. Cecil King's business: it must certainly have resulted in economic loss to the Process Industry.'

Contents:
Correspondence with publishers and others re publications by Young, 1949-68. The majority of the correspondence relates to Young's two books on Process Control and contains many appreciative comments on their usefulness for on understanding of the subject. In 1969 Young wrote:
'My "Introduction to Process Control System Design" was received with a degree of appreciation which was as surprising to me as it was pleasing. I am sure it was because many chemists and engineers, who were not versed in control, could understand what I had tried to say.
'This has encouraged me to proceed with the book I had originally planned to follow the "Introduction" to design: namely, "An Approach to the Design of Process Plant", or some title indicating that we have begun to use the basic approach advocated in the "Introduction".
