he history of chemistry is a story of human endeavor-and as er T ratic as human nature itself. Progress has been made in fits and starts, and it has come from all parts of the globe. Because the scope of this history is considerable (some 100,000 years), it is necessary to impose some order, and we have organized the text around three dis cemible-albeit gross--divisions of time: Part 1 (Chaps. 1-7) covers 100,000 BeE (Before Common Era) to the late 1700s and presents the background of the Chemical Revolution; Part 2 (Chaps. 8-14) covers the late 1700s to World War land presents the Chemical Revolution and its consequences; Part 3 (Chaps. 15-20) covers World War I to 1950 and presents the Quantum Revolution and its consequences and hints at revolutions to come. There have always been two tributaries to the chemical stream: experiment and theory. But systematic experimental methods were not routinely employed until the 1600s-and quantitative theories did not evolve until the 1700s-and it can be argued that modem chernistry as a science did not begin until the Chemical Revolution in the 1700s. xi xii PREFACE We argue however that the first experiments were performed by arti sans and the first theories proposed by philosophers-and that a rev olution can be understood only in terms of what is being revolted against.

Chemistry explores the way atoms interact, the constitution of the stars, and the human genome. Knowledge of chemistry makes it possible for us to manufacture dyes and antibiotics, metallic alloys, and other materials that contribute to the necessities and luxuries of human life. In Transforming Matter, noted historian Trevor H. Levere emphasizes that understanding the history of these developments helps us to appreciate the achievements of generations of chemists. Levere examines the dynamic rise of chemistry from the study of alchemy in the seventeenth century to the development of organic and inorganic chemistry in the age of government-funded research and corporate giants. In the past two centuries, he points out, the number of known elements has quadrupled. And because of synthesis, chemistry has increasingly become a science that creates much of what it studies. Throughout the book, Levere follows a number of recurring themes: theories about the elements, the need for classification, the status of chemical science, and the relationship between practice and theory. He illustrates these themes by concentrating on some of chemistry's most influential and innovative practitioners. Transforming Matter provides an accessible and clearly written introduction to the history of chemistry, telling the story of how the discipline has developed over the years.

William Newman and Lawrence Principe reveal the hitherto hidden laboratory experiments of a famous alchemist and argue that many of the principles and practices characteristic of modern chemistry derive from alchemy.

This classic exposition explores the origins of chemistry, alchemy, early medical chemistry, nature of atmosphere, theory of valency, laws and structure of atomic theory, and much more.
