Amy Dockser Marcus won the Pulitzer Prize because she can clearly explain things that are deeply confusing to so many of us. Amy understands – and can explain – the complex relationships between economics, society, health, and medicine. In a meticulously researched book, she talks about the remarkable accomplishments of “citizen scientists” – ordinary individuals who united to revolutionize what had been the traditional wisdom of medical researchers and professionals. At first glance, Amy’s new book looks like a medical chronicle, but look a little deeper and you’ll see a celebration of the powerful insights that can be offered by motivated amateurs in every field of endeavor.
