How an early modern surgeon and his accessible writings changed medical expertise and the communication of medical knowledge. Between 1497 and 1512, Hieronymus Brunschwig (c.1450-c.1530), an obscure craftsman from Strasbourg, wrote books on surgery and pharmacy that transformed medical expertise, how it was codified in print, and how it was communicated to new audiences. Brunschwig was an unlikely author. He apprenticed as a surgeon in the local guild and eventually kept his own apothecary shop. But he was remarkably well-read in surgery, alchemy, and medical theory, even if he lacked a university education. His unique authorial voice spoke to the healing practices of craftsmen and common people in a down-to-earth German dialect. Crafting Medicine by Tillmann Taape is the first in-depth study of Brunschwig and his works. In it, Taape argues that Brunschwig's writings shaped a nascent tradition of vernacular medicine. Brunschwig's books represent a key moment in the history of medical print, for they conveyed medical expertise to a new readership of non-academic practitioners, including laypeople who became a key audience for a flood of vernacular medical publications during the sixteenth century. Using Brunschwig's books as a unique window into the past, Crafting Medicine beautifully reconstructs the world of science inhabited by Brunschwig, his fellow craftsmen, his translators, and his readers.
