Ratio Club: A Brief History of British Cyberneticians

 

The Ratio Club: a melting pot for British cybernetics

 

When Alan Turing was working at Manchester University, he was invited to join the Ratio Club, a dining club comprised of a mixture of biologists and engineers with an interest in cybernetics. There he was able to air and discuss new research and draw inspiration from an eclectic, yet extremely gifted group of individuals. Wired.co.uk examines the club and its influence on British science.

The Ratio Club was a group of young academics who came together to discuss cybernetics. It was founded in September 1949 by neurologist John Bates at the National Hospital for Nervous Diseases.

The club gathered in a basement room below the nurses’ accommodation and over beer and food participants would listen to a speaker, then have a discussion. The other members were a combination of neurobiologists, engineers, mathematicians and physicists and included Alan Turing. Professors were banned; anyone promoted to this position was supposed to resign their membership.

The aim was to keep the atmosphere informal and the discussion flowing.

Cybernetics is the science concerned with the study of systems and how they interact with each other — be they natural systems or machines. The club met regularly between 1949 and 1955, with a final reunion meeting in 1958. Founder Bates believes that cybernetic ideas could be important tools for developing new insights into the nervous system.

The Ratio Club was noteworthy because many of its 21 members went on to become extremely prominent scientists. These included: – Horace Barlow, the great-grandson of Charles Darwin who has become an enormously influential neuroscientists specialising in the field of vision. – Thomas Gold, who became one of the most prominent astrophysicists of the 20th century and gave the first explanation of pulsars among many other contributions. At the time of the Ratio Club he was working in the Zoology department of Cambridge University studying the inner ear. – John Pringle was a leading invertebrate neurobiologist and was the first scientists to get recordings from single neurons in insects.

He went on to become professor of zoology at Oxford University. – Albert Uttley, who researched radar and automatic tracking during WWII. He later became the head of the Autonomics Division at the National Physical Laboratory where he researched machined intelligence and brain modelling. Later he became Professor of Psychology at Sussex University. – William Grey Walter was a world leader in EEG research, discovering the theta and delta brain waves and developing the first EEG brain topography machine. When he wasn’t researching EEG, he was developing the world’s first autonomous mobile robots, called Elmer and Elsie, which he used to study ideas about brain function.

Many of the club members were interested in developing brain-like devices as a means to either understand biological brains or develop machine intelligence. As a result the conversation tended to focus on the mechanisation of the mind.

Most Ratio talks provided an opportunity for members to discuss their current research. Turing led three different talks. His second talk on Educating a Digital Computer, which took place on 7 December 1950, introduced the Turing Test and focused on how intelligent machines might be developed. Turing suggested using adaptive machines that could learn over their lifetime.

Turing’s third talk at the club, in February 1952, described his then unpublished work on reaction-diffusion models of morphogenesis. This launched him into new directions of theoretical biology and was incredibly influential in the field of computer modelling.

It was through Turing’s communications with fellow Ratio Club members that he expressed his interest in using a computer such as the ACE to study the brain. In a letter to psychiatrist William Ross Ashby, he said: “In working on the ACE I am more interested in the possibility of producing models of the action of the brain than in the practical applications of computing.”

The club had run its course by the summer of 1955, a year after Turing had died from cyanide poisoning after having been chemically-castrated. By that point many of the members’ research had been recognised internationally and cybernetics had become a respected discipline.

From The Ratio Club: A Hub of British Cybernetics

The definitive list of twenty-one members, with very brief details of expertise and achievements, is given below. Of course these summaries are far too short to do justice to the careers of these scientists. They are merely intended to illustrate the range of expertise in the club and to give a flavour of the calibre of members.

W. Ross Ashby (1903-1972), trained in medicine and psychiatry, is regarded as one of the most influential pioneers of cybernetics and systems science. Author of the classic books Design for a Brain (Ashby 1952a) and An Introduction to Cybernetics(Ashby 1958), some of his key ideas have recently experienced something of a renaissance in various areas of science including Artificial Life and modern AI. At the inception of the club he was director of research at Barnwood House Hospital, Gloucester. He subsequently became a professor in the Department of Biophysics and Electrical Engineering, University of Illinois.

Horace Barlow FRS (1921- ), a great-grandson of Charles Darwin, is an enormously influential neuroscientist, particularly in the field of vision, and was one of the pioneers of using information theoretic ideas to understand neural mechanisms (Barlow 1953, 1959, 1961), a direct consequence of his involvement in the Ratio Club. When the club started he was a PhD student in Lord Adrian’s lab at the department of physiology, Cambridge University. He later became Royal Society Research Professor of Physiology at Cambridge University.

John Bates (1918-1993) had a distinguished career in the neurological research unit at The National Hospital for Nervous Diseases, London. He studied human EEG in research into voluntary movement and became the chief electroencephalographer at the hospital. The Club was his idea and he ran it with quiet efficiency and unstinting enthusiasm.

George Dawson (1911-1983) was a clinical neurologist at the National Hospital, Queen square. At the time of the Ratio Club he was a world leader in using EEG recordings in a clinical setting. He was a specialist in ways of averaging over many readings which allowed him to gather much cleaner signals than was possible by more conventional methods (Dawson 1954). He became Professor of Physiology at UCL.

Thomas Gold FRS (1920-2004) was one of the great astrophysicists of the 20thcentury, being a co-author, with Bondi and Hoyle, of the steady state theory of the universe and having given the first explanation of pulsars, among countless other contributions. However, he had no time for disciplinary boundaries and at the time of the Ratio Club he was working in Cambridge University Zoology Department on a radical positive feedback theory of the working of the inner ear (Gold 1948) – a theory that was, typically for him, decades ahead of its time. He went on to become Professor of Astronomy at Harvard University and then at Cornell University.

I.J. (Jack) Good (1916- 2009) was recruited into the UK top secret code cracking operation at Bletchley Park during the second world war, where he worked as the main statistician under Alan Turing and Max Newman. Later he became a very prominent mathematician, making important contributions in Bayesian methods and early AI. During the Ratio years he worked for British Intelligence. Subsequently he became Professor of Statistics at Virginia Polytechnic Institute.

W.E. Hick (1912-1974) was a pioneer of information theoretic thinking in psychology. He is the source of the still widely quoted Hick’s law which states that the time taken to make a decision is proportion to the log of the number of alternatives (Hick 1952). During the Ratio years he worked in the Psychology laboratory at Cambridge University. He went on to become a distinguished psychologist.

Victor Little (1920-1976) was a physicist at Bedford College, London, who worked in acoustics and optics before moving on to laser development.

Donald Mackay (1922-1987), trained as a physicist, was a very highly regarded pioneer of early machine intelligence and of neuropsychology. He was also the leading scientific apologist for Christianity of his day. At the birth of the club he was working on a PhD in the Physics department of King’s College, London. He later became a professor at Keele University where he founded the Department of Communication and Neuroscience.

Turner McLardy(1913-1988) became an international figure in the field of clinical psychiatry. He emigrated to the USA in the late 1950s to develop therapeutic techniques centred around planned environments and communities. Later he became a pioneer of understanding the role of zinc in alcoholism and schizophrenia. At the inception of the club he worked at Maudsley Hospital, London.

Pat Merton FRS (1921-2000) was a neurophysiologist who did pioneering work on control theoretic understandings of the action of muscles (Merton 1953). Later he carried out a great deal of important early research in magnetic stimulation of the cortex for which he is justly celebrated (Merton and Morton 1980). During the Ratio years he worked in the neurological research unit at the National Hospital. He later became Professor of Human Physiology at Cambridge University.

John Pringle FRS (1912-1982) was one of the leading invertebrate neurobiologists of his day. He was the first scientist to get recordings from single neurons in insects, something that had previously been thought to be practically impossible (Pringle 1938). He did much important work in proprioception in insects, insect flight and invertebrate muscle systems. At the birth of the club he worked in the Zoological laboratory, Cambridge University. He subsequently became Professor of Zoology at Oxford University.

William Rushton FRS (1901-1980) is regarded as one of the great figures in 20thcentury vision science. He made enormous contributions to understanding the mechanisms of colour vision, including being the first to demonstrate the deficiencies that lead to colour blindness (Rushton 1955). Earlier he did pioneering work on the quantitative analysis of factors involved in the electrical excitation of nerve cells, helping to lay the foundations for the framework that dominates theoretical neuroscience today (e.g. Rushton 1935). He worked at Cambridge University throughout his career where he became Professor of Visual Physiology.

Harold Shipton (1920- 2007) worked with Grey Walter on the development of EEG technology at the Burden Neurological Institute, Bristol. He was the electronics wizard who was able to turn many of Walter’s less than precise designs into working realities. Later he became a professor at The University of Washington at St. Louis, where he worked on biomedical applications. At the time of the Ratio meetings, his father-in-law, Clement Attlee, was prime minister of Great Britain.

D.A. Sholl (1903-1960) did classic research on describing and classifying neuron morphologies and growth patterns, introducing the use of rigorous statistical approaches (Sholl 1956). Most of the classification techniques in use today are based on his work. He also published highly influential papers on the structure and function of the visual cortex. He worked in the Anatomy department of University College, London where he became Reader in Anatomy before dying young.

Eliot Slater (1904-1983) was one of the most eminent British psychiatrists of the twentieth century. He helped to pioneer the use of properly grounded statistical methods in clinical psychiatry. Slater’s work with Rudin on the genetic origins of schizophrenia, carried out in Munich in the 1930s, still underpins all respectable Anglo-American work in psychiatric genetics, a field to which Slater made many important contributions (Slater et al. 1971). He worked at the National Hospital for Nervous diseases, London.

Alan Turing FRS (1912-1954) is universally regarded as one of the fathers of both computer science and artificial intelligence. Many regard him as one of the key figures in twentieth century science and technology. He also anticipated some of the central ideas and methodologies of Artificial Life and Nouvelle AI by half a century – for instance, he proposed artificial evolutionary approaches to AI in the late 1940s (Turing 1950) and published work on reaction-diffusion models of the chemical origins of biological form in 1952 (Turing 1952). At the inception of the club he was working at Manchester University, where he was part of a team that had recently developed the world’s first stored-program digital computer.

Albert Uttley (1906-1985) did important research in radar, automatic tracking and early computing during WWII. Later he became head of the pioneering Autonomics Division at the National Physical Laboratory in London where he did research on machine intelligence and brain modeling. However, he also became well know as a neuropsychologist, having made several important contributions to the field (Uttley 1979). At the birth of the club he worked at TRE, Malvern, the main British military telecommunications research establishment. Later he became Professor of Psychology at Sussex University.

W. Grey Walter (1910-1977) was a world leader in EEG research. He discovered theta and delta brain waves and, with Shipton, developed the first EEG brain topography machine (Walter and Shipton 1951). At the time of the Ratio Club he was at the Burden Neurological Institute, Bristol, where, alongside his EEG research, he developed the first ever autonomous mobile robots, referred to as tortoises, which were controlled by analogue electronic nervous systems (Walter 1950a). This was the first explicit use of mobile robots as a tool to study ideas about brain function, a style of research that has become very popular in recent times.

John Westcott FRS (1920- ) made many very distinguished contributions to control engineering, including some of the earliest work on control under noisy conditions. He also worked on applications of control theory to economics which resulted in his team developing various models used by the UK Treasury. At the inception of the club he was doing a PhD in the department of Electrical Engineering, Imperial College, London, having just returned from a year in Wiener’s lab at MIT. He later became Professor of Control Systems at Imperial College.

Philip M. Woodward (1919- ) is a mathematician who made important contributions to information theory, particularly with reference to radar, and to early computing. His gift for clear concise explanations can be seen in his elegant and influential 1953 book on information theory (Woodward 1953). He worked at TRE, Malvern throughout his entire distinguished career (one of the buildings of the present day successor to TRE is named after him). In retirement Woodward has come to be regarded as one of the world’s greatest designers and builders of mechanical clocks (Woodward 1995).

Bates’ own copy of his typed club membership list of 1st January 1952 has many hand-written corrections and annotations (Bates 1952a). Among these, immediately under the main list of members, are the following letters, arranged in a neat column: ‘Mc’, ‘P’, ‘S’ and then a symbol that may be a ‘U’ or possibly a ‘W’. If we assume it is a ‘W’, then a possible, admittedly highly speculative, interpretation of these letters is: McCulloch, Pitts, Shannon, Wiener. The first three of these great American cyberneticists attended club meetings – McCulloch appears to have taken part whenever travel to Britain allowed. Wiener was invited and intended to come on at least one occasion but travel difficulties and health problems appear to have got in the way. The ‘W’, if that’s what it is, could also refer to Weaver, co-author with Shannon of seminal information theory papers and someone who was also well known to the club. Of course the letters may not refer to American cyberneticists at all – they may be something more prosaic such as the initials of members who owed subs – but it is just possible that Bates regarded them as honorary members.

It is clear from the membership listed above that the centre of gravity of the club was in the brain sciences. Indeed the initial impetus for starting the club came from a neurologist (Bates) who believed that emerging cybernetic ideas and ways of thinking could be very important tools in developing new insights into the operation of the nervous system. Many members had a strong interest in developing ‘brain-like’ devices, either as a way of formalizing and exploring theories about biological brains, or as a pioneering effort in creating machine intelligence, or both. Hence meeting tended to centre around issues relating to natural and artificial intelligence and the processes underlying the generation of adaptive behaviour – in short, the mechanisation of mind. Topics from engineering and mathematics were usually framed in terms of their potential to shed light on these issues. This scope is somewhat different to that which had emerged in America, where a group of mathematicians and engineers (Wiener, von Neumann, Bigelow, Shannon, Pitts) and brain scientists (Lorente de No, Rosenblueth, McCulloch) had formed an earlier group similar in spirit to the Ratio Club, although smaller and with a centre of gravity further towards the mathematical end of the spectrum. Their influence soon spread, via Frank, Mead, Bateson and others, into the social sciences, thereby creating a much wider enterprise (Heims 1991). This difference in scope helps to account for the distinct flavour of the British scene in the late 1940s and for its subsequent influences.
