In Inventing Chemistry, historian John C. Powers turns his attention to Herman Boerhaave (1668—1738), a Dutch medical and chemical professor whose work reached a wide, educated audience and became the template for chemical knowledge in the eighteenth century. The primary focus of this study is Boerhaave's educational philosophy, and Powers traces its development from Boerhaave's early days as a student in Leiden through his publication of the Elementa chemiae in 1732. Powers reveals how Boerhaave restructured and reinterpreted various practices from diverse chemical traditions (including craft chemistry, Paracelsian medical chemistry, and alchemy), shaping them into a chemical course that conformed to the pedagogical and philosophical norms of Leiden University's medical faculty. In doing so, Boerhaave gave his chemistry a coherent organizational structure and philosophical foundation, and thus transformed an artisanal practice into an academic discipline. Inventing Chemistry is essential reading for historians of chemistry, medicine, and academic life.

In The Secrets of Alchemy, science historian and practicing chemist Lawrence M. Principe dispels commonly held misconceptions about alchemy and sheds light on what it was, how it began, and how it influenced a range of other ideas and pursuits. Principe demonstrates the importance of alchemy during its heyday in early modern Europe, and explores its enduring place in literature, fine art, theater, and religion as well as its recent acceptance as a serious subject of study for historians of science. Principe also introduces readers to some of the most fascinating alchemists, such as Zosimos and Basil Valentine, whose lives dot alchemy's long reign from the third century and to the present day. Through his discussion of alchemists and their times, Principe pieces together clues from obscure texts to reveal alchemy's secrets, and uses them to recreate many of the most famous recipes in his lab, including those for the "glass of antimony" and "philosophers' tree."
