This study is an outgrowth of our interest in the history of modern chemistry. The paucity of reliable, quantitative knowledge about past science was brought home forcibly to us when we undertook a research seminar in the comparative history of modern chemistry in Britain, Germany, and the United States. That seminar, which took place at the University of Pennsylvania in the spring of 1975, was paralleled by one devoted to the work of the "Annales School". The two seminars together catalyzed the attempt to construct historical measures of change in aspects of one science, or "chem ical indicators". The present volume displays our results. Perhaps our labors may be most usefully compared with the work of those students of medieval science who devote their best efforts to the establish ment of texts. Only when acceptable texts have been constructed from fragmentary and corrupt sources can scholars move on to the more satisfying business of making history. So too in the modern period, a necessary pre liminary to the full history of any scientific profession is the establishing of reliable quantitative information in the form of statistical series. This volume does not offer history. Instead it provides certain element- indicators -- that may be useful to individuals interested in the history of American chemistry and chemical industry, and suggestive for policy.

A Cultural History of Chemistry in the Modern Age covers the period from 1914 to the present. The impact of chemistry and the chemical industry on science, war, society, and the economy has made this era the “Chemical Age”. Having prospered in the West, chemical science spread across the globe and slowly became more diversified in terms of its ethnic and gendered mix. After flourishing for sixty years, the chemical industry was impacted by the Oil Crisis of the 1970s and became almost invisible in the West. While the industry has clearly delivered many benefits to society-such as new materials and better drugs-it has been excoriated by critics for its impact on the environment. The 6 volume set of the Cultural History of Chemistry presents the first comprehensive history from the Bronze Age to today, covering all forms and aspects of chemistry and its ever-changing social context. The themes covered in each volume are theory and concepts; practice and experiment; laboratories and technology; culture and science; society and environment; trade and industry; learning and institutions; art and representation.

How did chemistry and physics acquire their separate identities, and are they on their way to losing them again? Mary Jo Nye has written a graceful account of the historical demarcation of chemistry from physics and subsequent reconvergences of the two, from Lavoisier and Dalton in the late eighteenth century to Robinson, Ingold, and Pauling in the mid-twentieth century. Using the notion of a disciplinary "identity" analogous to ethnic or national identity, Nye develops a theory of the nature of disciplinary structure and change. She discusses the distinctive character of chemical language and theories and the role of national styles and traditions in building a scientific discipline. Anyone interested in the history of scientific thought will enjoy pondering with her the question of whether chemists of the mid-twentieth century suspected chemical explanation had been reduced to physical laws, just as Newtonian mechanical philosophers had envisioned in the eighteenth century.
