There's no doubt about it, medicine has come a long way over the past century. But, ask Wisconsin historian and author Erika Janik and she'll tell you, medicine in the 19th century wasn't all snake oil and trickery. While Publisher's Weekly says Janik's "Marketplace of the Marvelous: The Strange Origins of Modern Medicine," is "a must-read for medical history buffs," the book is, in fact, a fascinating and readable look into the roots of modern medicine, with some bonus ties to Wisconsin for hometown readers.
