Last month, a commenter at this blog’s blogfather, AdvoAdvo, if you read this, please drop me a line so that I can thank you directly., recommended Thomas Hager’s The Demon Under the Microscope: From Battlefield Hospitals to Nazi Labs, One Doctor's Heroic Search for the World's First Miracle Drug (2006) (Demon). This book offers an interesting, well-written popular account of the discovery of the first widely effective class of antibiotics, the sulfa drugs, and its discoverer, Gerhard Domagk. That account covers some of the same events recounted in this blog last year. While these accounts largely agree where they overlap, there are some discrepancies which deserve pointing out and at least an attempt at resolution.
