Combining scrupulous textual analysis of Isaac Newton's surviving alchemical manuscripts, some examined for the first time, with extensive replications of his actual laboratory operations, William Newman provides a fresh and convincing new road map of Newton's decades-long journey of chymical inquiry. An engaging read, and a scholarly triumph. --Alan Rocke, Case Western Reserve University The topic of Newton's alchemy has been a cause c l bre for more than a generation, thanks to what too many people have viewed as a puzzling juxtaposition between the 'rationalist scientist' Newton and 'irrational, pseudoscientific' alchemy. The time is ripe for a new understanding of Newton and alchemy, and there is certainly no more capable person to do this than William Newman. --Lawrence M. Principe, author of The Secrets of Alchemy Newton the Alchemist is a tour de force proving beyond any doubt Newton's extraordinary debt to 'chymistry, ' the alchemical art of analysis and synthesis. A magnificent achievement, this book stands as the definitive treatment of Newton on alchemy. --Jed Z. Buchwald, coauthor of Newton and the Origin of Civilization [A] brilliantly detailed book. . . . Newman's patient research has produced a masterpiece of scientific history . . . that will still be read in a century. ---Dmitri Levitin, Literary Review
