Before Henry Guerlac's book, we knew little about the reasons that led the great chemist Antoine-Laurent Lavoisier to discover the role of air in combustion. Henry Guerlac finds that this breakthrough that began the Chemical Revolution did not come "ex nihilo," as many historians claim. Rather, it marked the culmination of research by British and French chemists, radically refashioned by Lavoisier and his disciples. Henry Guerlac portrays Lavoisier integrating Continental and British chemical traditions. Like New ton in physics and Darwin in biology, Lavoisier was a revolutionary. This work presents his in a vigorous and innovative light.

Through his development of quantitative experimental methods, the chemist Antoine Lavoisier (1743-1794) implemented a principle that many regard as the cornerstone of modern science: in every operation there is an equal quantity of material before and after the operation. The origin of Lavoisier's methods, however, has remained a missing piece in this remarkable episode of scientific history, perhaps because the talented young scientist himself was not prepared for the journey his discoveries would set before him. In this book, Frederic Holmes suggests that Lavoisier gradually came to understand the nature and power of his quantitative method during the year 1773, when he began to carry out a research program on the fixation and release of airs. Drawing upon Lavoisier's surviving laboratory notebooks, Holmes presents an engaging portrait of a scientist still seeking the way that would lead him to become the leader of one of the great upheavals in the history of science. Holmes follows Lavoisier day-by-day at work in his laboratory over a course of several months. The scientist's resourcefulness and imagination spring to life in this account, as does his propensity to make mistakes, which taught him as much as his successes. During the course of this odyssey, Lavoisier saw his early theory of combustion collapse under the weight of his own efforts to provide experimental evidence to support it. In compensation, he acquired a method and the hard-won experience on which he would later construct a more enduring theoretical structure. Originally published in 1997. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The author explores the origins of the eighteenth-century chemical revolution as it centers on Antoine-Laurent Lavoisier's earliest work on combustion. He shows that the main lines of Lavoisier's theory—including his theory of a heat-fluid, caloric—were elaborated well before his discovery of the role played by oxygen. Contrary to the opinion prevailing at that time, Lavoisier suspected, and demonstrated by experiment, that common air, or some portion of it, combines with substances when they are burned. Professor Guerlac examines critically the theories of other historians of science concerning these first experiments, and tries to unravel the influences which French, German, and British chemists may have had on Lavoisier. He has made use of newly discovered material on this phase of Lavoisier's career, and includes an appendix in which the essential documents are printed together for the first time.
