Chang/ID20050048/Item4 Detailed Research Description Item 4. Detailed Research Description Analysis and Synthesis in 19th-Century Chemistry: Toward a New Philosophical History of Scientific Practice 1. Objectives The overall aim of this project is twofold: first, to write a history of 19th-century chemistry focused on the development of laboratory practices; second, through this concrete history, to showcase a philosophical history of scientific practice. By a "philosophical history" of science I simply mean an investigation of the development of scientific knowledge. While that is a traditional aim, I reject the traditional view that knowledge consists of propositions and that the main aim of scientific activity is to ascertain the truth-value of propositions. Instead, following Michael Polanyi (1958), Ian Hacking (1993) and Peter Galison (1997) for example, I believe that knowledge consists of practices as well as propositions. A philosophical history of scientific practice must synthesise the study of instruments, operational techniques, manual skills and laboratory spaces, as well as concepts, hypotheses, and metaphysical assumptions, and also the pedagogical practices and community interactions that underlie all other elements. Moving away from propositions and their truth-value as the exclusive focus of philosophical study allows some fresh answers to a familiar question: what are the aims of scientific practice? It is useful to recall the common view of 18th-century chemists, that chemistry was a study of how substances could be broken down and re-combined: in other words, analysis and synthesis. What kind of knowledge was gained from such activities? The answer is a long and untidy list: the existence of new elements and new compounds; methods of discovering, manufacturing and purifying substances; the ability to define and identify substances by key properties; the composition and structure of compounds; the assessment of affinities and forces presumed to direct chemical reactions; the relationship between the properties of the ingredients and products of chemical reactions; and so on. Taking these various types of knowledge as the aims of chemical practice opens up numerous avenues of research that tend to be closed off by a preoccupation with truth and theory-testing. More specifically: my collaborators and I will attempt to re-tell the story of chemistry from the late 18th century to the late 19th century through a study of the development of the methods of analysis and synthesis. I came to a clear realisation of the potential of this type of historiographical approach in the course of writing my recently published book (Inventing Temperature: Measurement and Scientific Progress, Oxford University Press, 2004), which made a thorough study of the development of thermometry. In that study, following through the development of one laboratory practice illuminated many neglected aspects of the history of physics, chemistry and other sciences, and revealed a new coherence to the history that was obscured by the more 1 Chang/ID20050048/Item4 Detailed Research Description traditional focus on theoretical ideas or major experimental discoveries. I expect the same kind of benefit from our projected study of chemical analysis and synthesis. The redefinition of knowledge to give prominence to practices will bring to the fore many significant aspects of science that are so often entirely overlooked in historical accounts. 2. Background In recent historiography of chemistry, there has been a misguided reaction against a grand tradition of intellectual history, perhaps exemplified most exuberantly in the work of James Riddick Partington (1961-70). This tradition was particularly robust in the years around 1970 (e.g., works of David Knight, Mary Jo Nye, Arnold Thackray, William H. Brock, John H. Brooke, Robert Fox, and Frederic Holmes). Perhaps the criticism was justified that these excellent histories were much too "theory-dominated" and not sufficiently contextual, and we have certainly gained valuable new understanding from the more recent focus on the social, cultural and institutional setting of chemists and chemistry. However, the newer trend has also spread an unhelpful notion, that the history of chemistry (and of science in general) should concern itself mainly with the social and cultural meaning of science, rather than scientific knowledge itself. This marginalisation of scientific knowledge itself has made the history of science appear irrelevant not only to many philosophers of science, but to many practising scientists as well. In my view, a resolute focus on understanding scientific practice is the key in unifying social and intellectual approaches to the history of chemistry, returning chemical knowledge to the centre of the history of chemistry, while taking a full and well-rounded view of that knowledge. In forging this new direction, my collaborators and I will build on the following helpful strands in existing literature in the history, philosophy and sociology of science. Philosophy of experiment. Philosophers such as Polanyi (1958) and Hacking (1983) effectively emphasised the importance of understanding scientific practice, but did not write detailed histories. We seek to apply their insights in our work, focusing particularly on the tacit dimensions of experimental practice, and the development of manipulative skills. Galison's (1997) study of experimental practices in modern high-energy physics can be taken as a good model, and more sociological studies such as those by Harry Collins (1985) and Simon Schaffer (1989) can also provide some guidance. More recent studies include those collected in Radder (2003). Research schools. As J. B. Morrell put it in a retrospective account (1993, 124), the concept of research schools "suggested a way in which social history of science could be written which did not downgrade science as cognition", and it is exactly this fruitful avenue that our study aims to pursue. Morrell's introduction of the concept in 1972 marked a watershed, and subsequent elaboration and application of his ideas by Joseph Fruton (1988, 1990), Gerald Geison (1978, 1981, 1993), Frederic Holmes (1989, 1993), Mary Jo Nye (1993b), and Alan Rocke (1993) have demonstrated its usefulness. 2 Chang/ID20050048/Item4 Detailed Research Description Pedagogy. The study of research schools made explicit the link between teaching and research, a connection expertly explored by Holmes’ (1989) study of Justus von Liebig’s laboratory. It is generally accepted that the introduction of a routine method of combustion analysis was at least a contributory factor in the increased research output of laboratories such as Liebig’s in the 1830s and 1840s. Andrew Warwick’s (2003) study of 19thcentury mathematical physics in Cambridge argues that the development of the esoteric skills of the mathematical physicist implicated the whole student, mind and body, in both professional and social life. Some of these themes can be detected in the research schools of Liebig and August Wilhelm Hofmann for example, but there has so far been no attempt to study chemical pedagogy in the 19th century in equivalent detail. Institutions. Morrell’s identification of institutional and financial factors as key to the success of research schools has been utilised by Gerrylynn Roberts (1976) in her study of the Royal College of Chemistry and, later, in Rocke's (1993) comparison of the Marburg and Leipzig schools of Hermann Kolbe. Institutional developments in chemistry throughout our period of study are closely interwoven with professionalisation and the growth of a community of chemists, as studied by Karl Hufbauer (1982) in 18th-century Germany and Robert Bud and Roberts (1984) in 19th-century Britain. In this context, the Royal Society of Chemistry, founded in 1841, and the Deutsche Chemische Gesellschaft, founded in 1867 in emulation of the British society by Hofmann, will be worth studying. Laboratories. History of chemistry has long been concerned with laboratories, as for example in Smeaton (1954), which traced the origins of the Giessen laboratory to Gay-Lussac's 18th-century Parisian laboratory. Such studies are helpful, but there are clear gaps we would like to fill. Even recent works including Crosland (2005) have tended to focus on the period up to Giessen, and there seems to be a general tendency to assume that the design and operation of laboratories for chemistry was relatively static after that. Moreover, there has been no treatment of chemistry laboratories similar to David Cahan's comprehensive study (1985, 1989) of the laboratory revolution in German physics in the 1870s, despite the fact that similar developments in chemistry laboratories occurred in Germany from the 1860s onwards. History of analytic chemistry. It seems that Ferenc Szabadváry's 1960 text is still unsurpassed as a comprehensive introduction to this subject, and it provides very useful details on analytic techniques. Similarly, discussions by Ida Freund (1904) are still helpful. Brock (1992, chapter 5) gives a more recent view and provides an extensive bibliography. History of synthetic organic chemistry. There are currently no histories entirely devoted to synthetic organic chemistry, and few histories of organic chemistry in general. The most relevant to our study are those by Carl Schorlemmer (1879) and Carl Graebe (1920), eminent organic chemists of the late 19th century, although modern contributions such as Russell (2004) provide a useful and accessible overview. Two articles by John Brooke (1968, 3 Chang/ID20050048/Item4 Detailed Research Description 1971) deal with the implications of synthesis for vitalism and disciplinary definition, whilst Russell (1987) tackles the many and various meanings and significance of synthesis to the development of 19th-century chemistry. Since then, however, the only recent attempt to write specifically about organic synthesis has been the popular history by John Buckingham (2004). 3. Hypotheses In our study, we will seek to test the following specific hypotheses. (a) Analytic continuity. A focus on analytic techniques will reveal a surprising degree of continuity of development lasting through the phlogiston theory, pneumatic chemistry, the Chemical Revolution, Dalton's atomic theory, etc., up to the middle of the 19th century. Chemistry was defined by Lavoisier in 1787 as the science of analysis, and this understanding of chemistry as a quest to determine the elementary composition of substances was common for many decades afterwards. The goals and methods of analysis were varied (ranging from the field analysis of rock samples to determine their mineral content, to attempts to settle theoretical disputes concerned with the fundamental nature of matter), but the same techniques were applied in very different contexts. The relation between analytic methods and theoretical ideas is complex, and the two are not always well-coordinated with each other. But there is also a sense in which analytic practice set the agenda for theoretical developments in the earlier period of our study; long-lasting theoretical elements, such as the concepts of affinity and equivalents, seem to have been closely tied with analytic methods. (b) The role of organic chemistry in the evolution of analysis. During the 18th century, the subjects of analysis were predominantly inorganic, but by the beginning of the 19th century the isolation of increasing numbers of organic materials necessitated the development of new analytical methods. The main techniques in quantitative inorganic analysis were based on the precipitation of insoluble salts and the accurate measurement of gas volumes, whilst the blowpipe was invaluable in mineralogy. Jons Jakob Berzelius and Joseph-Louis Gay-Lussac were instrumental in the development of these techniques, which became part of the training of chemists around the turn of the century. As chemists turned their attention increasingly to the organic world, the problems of analysis changed. Since Lavoisier's time, the composition of organic matter had been obtained by combustion, trapping the carbon dioxide gas and water vapour produced, and measuring their volume to determine the amount of carbon and hydrogen present in the sample. The first major innovation, due to Gay-Lussac, involved the use of anhydrous calcium carbonate, a deliquescent substance that trapped water vapour. The later and much more famous change was made by Liebig, who introduced the Kaliapparat, a five-balled glass vessel filled with alkaline potash that trapped passing acidic carbon dioxide gas. 4 Chang/ID20050048/Item4 Detailed Research Description (c) Synthetic revolution. A shift of focus from analysis to synthesis took place in the mid-19th century, marking a watershed in chemistry’s methods and goals, as well as in its philosophical and theoretical allegiances. Studies of the chemical transformations of organic materials, including Wöhler's 1828 preparation of urea, suggested the possibility of making compounds from simpler substances, or even from their constituent elements. The clearest defining point in this shift was probably Hermann Kolbe's 1845 synthesis of acetic acid, an event singled out by Graebe (1920) as marking the onset of the second age of synthesis. Although the first fully planned synthesis did not occur until Adolf Baeyer's synthesis of indigo, by the mid19th century organic chemistry was beginning to effect a major redefinition of chemistry in terms of synthesis, and the ability to make things became a prevalent concern. Organic synthesis came to dominate chemical research so much as to make Carl Fresenius feel the need to found a separate haven for analysis, in the form of the journal Zeitschrift für Analytische Chemie, in 1862. In modern times, synthesis came to be regarded as the ultimate test of the chemists' skill and power over nature. (d) Synthesis and structural theory. Synthesis had implications that were not restricted to industrial applications, but also affected structural theory. As the number of organic substances that had been isolated and analysed increased ever more rapidly, more subtle problems in the relationship between composition and structure became apparent. In particular, the relative inaccuracy in the determination of the nitrogen content of alkaloids, despite many improvements in experimental method that utilised a similar strategy to Liebig's Kaliapparat, led to significant uncertainty about the elemental composition assigned following combustion analysis. The discovery of isomerism cast further doubt on the sufficiency of composition in defining substance, and made chemists increasingly aware of the need for improved structural theories. Syntheses offered the possibility of confirming structure, and it was for this purpose, as well as the more frequently acknowledged industrial and commercial reasons, that synthesis came to dominance in the last quarter of the 19th century. Thus the implications of synthetic chemistry are not restricted, as current historiography so often implies, to issues concerning industrial application (e.g. Meinel and Scholz 1992, Travis 1993), the validity of vitalism (e.g. Brooke 1968, Russell 1987), and disciplinary definition (e.g. Brooke 1971). (e) Impact on styles of research and teaching. The development of analytic and synthetic techniques created deep and far-reaching changes in the styles of research and teaching. Liebig's introduction of the Kaliapparat is inextricably associated with the introduction of systematic laboratory training into chemistry, and with a substantial scaling-up of chemical research through the provision of a routine research method. Analysis became a routine and highly replicable technique, and the cutting edge of research in organic chemistry shifted to the domain of synthesis. Not only was this change reflected in the organisation and construction of laboratories, but it also led to the incorporation of new bodies of knowledge into the basic training of chemists, and the alteration of systems of examination to take account of these changes. Later, the new emphasis on 5 Chang/ID20050048/Item4 Detailed Research Description synthesis was reflected in entirely new laboratory environments, including much new apparatus as well as in novel systems of training. Interestingly, synthesis never became routine in the same way as analysis, and it remains an art up to the present. The "laboratory revolution" in chemistry was not a single event achieved by Liebig, but a long, complex process of evolution during the mid–19th century that culminated in a style of teaching/research laboratory (building, apparatus, and use) that persisted into the 20th century. 4. Research methods The chief method of research that we wish to employ is simple, in general terms: we identify key methods of analysis and synthesis, and follow their development, paying attention to all relevant factors. This allows us to cut through the more customary divisions of history in terms of dominant theories, national communities, or simple chronological periods. In the realm of analysis, the most important and interesting methods to be studied include: the use of the blowpipe, precipitation, electrolysis, and combustion analysis. In the realm of synthesis, the chief methods involved: some standard techniques, such as heating in a sealed glass tube; heuristic theoretical devices, such as substitution; and the development and application of new reagents. Each practical method is a complex entity, and to understand it fully requires an investigation of its justification, execution, and understanding. Each method has contexts in which it is motivated and employed most effectively; these contexts may be technological, or theoretical. For each analytic/synthetic operation, appropriate starting materials must be prepared and purified, and appropriate apparatus manufactured and standardised. Then the operation itself must be performed, correctly with requisite skill. Afterwards the products of the operation must be identified clearly and correctly. And then some understanding of what happened in the operation must be reached; in that process theories, models and metaphysical beliefs become explicitly relevant, though they may have played subtle yet important roles all along. To help us understand all of the above factors, we propose the following as key areas to be investigated, in their relation to the development of each method. Theoretical contexts. We will pay close attention to the interaction between the development of laboratory practices and the development of theories. We will examine some classic theoretical debates (involving phlogiston/oxygen theories, the atomic theory, and Prout's hypothesis) through the development of chemical analysis, and show how these debates shaped analysis and at the same time were shaped by analysis. We will also examine the close connection between analytic methods and the concepts of affinity and equivalents. On the synthesis side, the relation between laboratory practice and structural theory (e.g. type theory) requires careful examination, and we will be helped by considering Ursula 6 Chang/ID20050048/Item4 Detailed Research Description Klein's (2003) concept of "paper tools" and its methodological implications. In this context we will also test the usefulness of the recent philosophical works on models (e.g. Morgan and Morrison 1999). Material culture. It will be essential for us to make a careful and extensive study of the apparatus used for analysis and synthesis, and the laboratory environments that developed around the apparatus. There is a good deal of secondary literature on the blowpipe, the Kaliapparat and other analytic apparatus, though less on synthetic apparatus. In the later period, glassware, glassblowing and the development of controlled environments for synthesis become vital. A close study of chemical publications will be undertaken to glean crucial experimental details. Fortunately there are valuable museum collections to be studied, for example at the Deutsches Museum in Munich, at the Whipple Museum in Cambridge, and at the Science Museum in London. We will also examine various catalogues from instrument makers (e.g. John Griffin) to track the evolution and availability of standard apparatus. Many new chemical laboratories were built during the 19th century, and studying their structure and operations will generate valuable insights. We intend to study the creation of the new laboratories of the Royal College of Chemistry in London, and its successor laboratories in South Kensington. Although no plans for the Royal College of Chemistry appear to remain, there is evidence to be gleaned from the archival sources held at Imperial College London. Plans exist for many other chemical laboratories built during the 19th century, including Hofmann’s 1866 report on the Bonn and Berlin University Laboratories that he designed. In addition, Engel and Engel (1992) contains plans available for many laboratories that relate directly to this story, including the Gewerbe Akademie in Berlin. Pedagogy. A most instructive window on the development of scientific practice is the training of students. Chemical textbooks will be examined not only for their specific content, but also with attention to their pedagogical methods and orientation. On chemical analysis there were a large number of textbooks in this period, by Kirwan, Berzelius, Faraday, Griffin, Rose, Will, Hofmann, etc. Textbooks on synthesis are harder to find; Berthelot’s books are more philosophical polemic than textbooks. Various sets of lecture notes and examination papers are available at various teaching institutions; Catherine Jackson has already studied Watson's notes from Hofmann's lectures, and the exams at the Royal College of Chemistry and the Royal School of Mines in London. In addition, various personal accounts of chemists' practical training are available in the literature (e.g. Armstrong 1896). Key figures, institutions, and their interactions. Although our focus is not on biography, it will be beneficial to identify clusters of key actors at various stages in the story. The earlier (analytical) period was dominated by the towering figures of Berzelius, Gay-Lussac, and Liebig, and this triumvirate neatly spans significant national boundaries. Prior work by Nye (1993a, 1993b) has addressed the different national styles of French and German chemists in the 19th century, and one of our strategies will be to 7 Chang/ID20050048/Item4 Detailed Research Description examine how the centres of expertise in chemistry moved around Europe during this period; for example, Liebig's pupil Hofmann was a key figure in the development of the new discipline of organic chemistry in Britain. Equally important is Edward Frankland, whose work on sealed-tube reactions and the use of organozinc compounds provided Hofmann with many of the chemical transformations that enabled his research programme into organic nitrogen bases. In order to provide the context for the work carried out by these major chemists, we will also study the institutions in which they worked. Most significant amongst these will be some of the German universities (notably in Giessen, Bonn and Berlin), the Royal College of Chemistry in London, and professional institutions including the Chemical Society, the German Chemical Society, and the Prussian Academy of Sciences. Contexts of application. Both analysis and synthesis have had wide applications in industry. While analysis was a necessary tool in many existing industries from mining to brewing, synthesis provided the foundation for entirely new industries. William H. Perkin's preparation of mauve spawned the synthetic dye industry of the late 19th century; the growth of this industry, as described in Travis (1993), was intimately connected with developments in laboratory synthesis and the technology of large-scale commercial preparation. Two key syntheses (alizarin in 1869 by Graebe and Liebermann, and indigo in 1880 by Baeyer) ensured German dominance. Understanding why these syntheses were achieved in Germany and not, for example, in England, will illuminate the relationship between academic and industrial chemistry during this period. In addition, our study of texts and artifacts will be supplemented by the replications of some key experiments. Historians of science have made various replications of classic experiments in recent decades for various reasons; representative works include those by Peter Heering (1992), Otto Sibum (1995) and, more recently and in an area directly relevant to our study, Melvyn Usselman et al. (2005). Our particular purpose in making replications is twofold: first, to ascertain the relevant phenomena for ourselves where the reports in primary sources are puzzling; second, and perhaps more importantly for this study, to help us understand the implicit and tacit dimensions of the practical work, which are not (and perhaps cannot be) specified in the published records. We expect to start with exploratory efforts in the first two years of the project, to intensify the activity in the final year. 5. Significance of our work If successful, our project would constitute a considerable achievement, making the following significant contributions: We would write a new history of chemistry from the late 18th century to the late 19th century, illuminating practical as well as theoretical developments. 8 Chang/ID20050048/Item4 Detailed Research Description Through our philosophical history of chemical practice, we would achieve a productive and meaningful synthesis between intellectual and social history. Our work would also pose an exciting challenge for philosophy of science and epistemology, by consolidating a broader conception of scientific knowledge. Consequently, we would breathe some new life into the history of chemistry in general, and emphasise that it can contribute to topical agendas in history and philosophy of science. We would also provide chemists with a history that is recognisable to them in relation to their day-to-day activities and that captures features of their systems of training and methods of research. 6. Plans for publication The output from our project will take four main forms. (1) The named PhD student, Catherine Jackson, will produce a dissertation on the part of the project focused on chemical synthesis, under my supervision. We expect the dissertation to lead to publications, in part or whole. (2) The unnamed postdoctoral researcher will be expected to publish a series of articles in refereed journals (possibly co-authored by myself in some cases), on the part of the project focused on chemical analysis. (3) We will also aim to produce publications that unite the two halves of the project. If our research is as successful as we are hoping, there will be scope for a book co-authored by all three of us. (4) In addition, the fruits of this project will also constitute helpful background material for a book I will be writing in the next 3-4 years, provisionally titled Air and Water: the Making of the Modern Physical Universe. 7.
