Destroying Angel: Benjamin Rush, Yellow Fever, and the Birth of Medicine by Bob Arnebeck

About a great man and eminent physician and devout Christian at the cusp of either the end of ancient medicine or the dawn of modern medicine and hence an agonizing portrayal of a devoted doctor facing a terrifying illness armed with unhelpful theories and no effective weapons. The writer both understands and misunderstands, seeing his medical efforts but blind to his spiritual integrity, seeing it only as undeveloped as his medical understanding.
