Studying up on the history of chemistry in order to better teach it, and this book has been very helpful in that pursuit. Levere covers a lot of ground in an accessible manner, and he steps beyond a mere catalogue of discoveries to give a more comprehensive picture of how the landscape changed over time. It is nice, in the modern era, to enjoy an account of the history of scientific progress that is not overeager to dismiss the theories and reasoning of the past as primitive and irrelevant. Levere gives due time and consideration to the roots, not only of theories but of basic concepts that still inform the practice of chemistry in the modern day.
