In writing this book, I have been fortunate to have many people review, edit, and inspire. I want to acknowledge Kirvin Gilbert, Lisa Macklin, James Curran, Alicia Hidron, Elissa Meites, Abeer Moanna, Mark Mulligan, David Rimland, Robert Rosman, and Michael Schlossberg for their help and encouragement. I also want to recognize the love and support from my children, Sara and Matthew, and most of all, my wife, Sherry. vii This page intentionally left blank PREFACE History is simply the biography of the mind of man; and our interest in history, and its educational value to us, is directly proportionate to the completeness of our study of the individuals through whom this mind has been manifested. To understand clearly our position in any science today, we must go back to its beginnings, and trace its gradual develop- ment. Sir William Osler In 2008, I gave a seminar to the Emory Division of Infectious Dis- eases on the history of our field using short biographies of the people who changed it. I began at the initial stages of Western medicine in ancient Greece and ended with the discovery of penicillin and the beginnings of modern antimicrobial therapy. The reaction that I received was the inspiration for this book. Faculty, fellows, post- doctoral students, residents, and medical students all appreciated the seminar and commented on their lack of acquaintance with the historical roots of their chosen discipline. A presentation at the Cen- ters for Disease Control and Prevention (CDC) some months later yielded similar comments from those in public health. Designed to describe the genesis of the germ theory of disease by those whose discoveries shaped our understanding of it, this book is intended not just for physicians or students of medicine but to be accessible to anyone with an interest in microbiology, infectious diseases, medical history, and, to a degree, biography. I have chosen to weave the narrative of the origins of the germ theory of disease through short biographies of the 11 men and 1 woman who changed the very fabric of our knowledge. Guided by ix
