I just finished the book To Catch a Virus. This book is focused on the developments in diagnostic virology that have shaped the way modern medicine confronts viral infections. What is most attractive about this book is that it details the discovery in a chronological fashion stressing the conceptual links between discoveries. For example, the development of PCR testing is handled in a manner in which one is able to see the progression from Oswald Avery to Kary Mullis without difficulty. Additionally, the book stresses the inductions made by various investigators providing a treasure trove of material for historians and philosophers of science. I highly recommend the book.
