Serendipity — Science 1: The Medicine and Vaccines That Arrived by Surprise

We like to believe medicine advances in straight lines — problem, hypothesis, experiment, cure. The truth is messier and far more astonishing: a startling amount of what keeps us alive was found by people who were looking for something else. Volume three of the Serendipity series turns from the kitchen and the battlefield to the laboratory and the clinic, with thirteen true stories of cures that arrived by accident. A bacteriologist returns from holiday to a moldy dish he should have thrown away, and the antibiotic age begins. A physicist sees a screen glowing across a darkened room and within months doctors everywhere are looking through flesh to the bones beneath. An engineer grabs the wrong electronic part and builds, by mistake, a circuit that beats like a heart. A chemist’s forgotten broth of chicken cholera gives birth to the modern vaccine. From penicillin, X-rays, and the pacemaker to Jenner’s milkmaids, Pasteur’s chickens, insulin, streptomycin, the PCR revelation on a California highway, Gram’s bacterial stain, the dawn of anesthesia, monoclonal antibodies, and cryosurgery, each chapter explains the science from scratch and tells the real, human story. And because we so badly want our healers to be lone heroes with tidy eureka moments, this book does what most do not: it separates documented fact from the romantic simplifications, the disputed credit, and the names left off the Nobel — with legend set in its own type. Guided throughout by Pasteur’s great maxim that “chance favors only the prepared mind,” it is a moving reminder that the cure is often an accident, but never only an accident — and that some of these discoveries were given freely to the world.
