I am also much in- debted to friends and colleagues. I would especially like to thank Lawrence Principe, William Brock, David Farrar, Anthony Fernandez, and Brian Baigrie for their comments on drafts of this book. I have cheerfully and gratefully adopted many of their suggestions. They have saved me from numerous er- rors, suggested the inclusion of several important topics, and helped me at many points to make arguments clearer. Juliana McCarthy at the Johns Hop- kins University Press was most helpful and efficient at every stage of produc- tion. Introduction Chemistry today is fascinating and far ranging. We know something about the chemistry of the stars, distant crucibles where elements are formed. We know much about the chemistry of life—in biochemistry, complexity and richness are at their peak, supported by elegant and often simple concepts and models. There are just over a hundred kinds of chemical atoms, corresponding to the different kinds of chemical elements, but their possible and actual combina- tions are so many as to seem infinite. In only the past thirty years, the list of known compounds has grown by seven and a half million, which represents almost a tenfold increase in that short interval of time. Complexity, richness, and an economy of means give chemistry its intellectual appeal; utility and ap- plication, its universal relevance. Chemistry in medicine, agriculture, and in- dustry and in its effects on the environment has transformed the conditions of life for our species, and for countless other species as well. Many of the neces- sities for our crowded planet are made possible by the applications of chem- istry. Many of the problems that we have created while providing those neces- sities are also tied to chemistry, and so too will be their solutions. We make choices, perceive needs, and create social and political structures in which we use, wittingly and unwittingly, the science of our day. Although chemistry has been important for millennia in its practical ap- plication to the needs and luxuries of human life, the discipline has not always been called chemistry. It has existed in very different forms, and in very differ- ent relations to neighboring sciences and crafts, in a flux that only accelerated as the years passed. The goals and concepts of a Chinese or Arabic alchemist of antiquity or the Middle Ages differed greatly from those of a chemist of the eighteenth-century Enlightenment, just as the aims and ideas of nineteenth- century research chemists were different from those of their predecessors and successors. Chemistry has, historically, been in constant flux, both in its self-image and in relation to other disciplines that sought to co-opt or absorb it. It has had its sects, its rivalries, and many dead-ends. But from antiquity to the present, there
