This book represents the very best kind of science writing: tart, concise, erudite and eclectically well informed. Granted, this book is not aimed at the average reader, you must have a fairly good working knowledge of protein chemistry. Indeed, the authors explicitly state that this book is meant for young researchers in the field of proteins (me): it can get very technical in places. The authors hope to plug a lacuna in the knowledge of proteins that is not taught in universities for very good reasons. History often makes the learning of new concepts difficult (although there are equally good reasons for teaching it - re. the Mach-Maxwell debate in the teaching of physics in Germany in the nineteenth century).
The authors have found the most marvellous materials - obscure researchers, long-forgotten debates, the wonder of discoveries as it was felt at the time. Indeed, what makes the book come alive is that discoveries are described in the context that they were made - both in terms of alternatives and the fractious infighting they sometimes engendered. Here, an appreciation of the technical details is an absolute must to truly appreciate the writing.
Historical context is judiciously included. When it is necessary, for instance, to understand how certain labs came into prominence or how ideas criss-crossed the globe. However, historical context is not slavishly used to structure the book. Some discoveries logically engender other discoveries. Too much focus on the historical context would lose the thread of the ideas. There are some of the most delicately rendered biographies, although thankfully, these are only kept at a minimum, a couple of paragraphs or so - after all, most scientists are not that interesting as people.
Finally, the authors have held no punches. In one place, they dismiss the work of a Nobel prize winner after winning the prize as a waste of time.
However, one vital ommision must be said (as noted in the review of this book in Nature). The Nobel-prize winning work of Anfinsen in showing that denatured proteins can refold is reduced to a single footnote. Given the generosity they have shown in other places, this is suprising.
