a new methodology, ”agnotology” (defined as the cultural history of ignorance), she explores the movement, triumph, suppression, and extinction of the diverse knowledges in the course of eighteenth-century encounters between Europeans and the inhabitants of the Caribbean—both indigenous Amerindians and African slaves. While much history of colonial science has focused on how knowledge is made and moved between continents and heterodox traditions, Schiebinger explores instances of the nontransfer of important bodies of knowledge from the New World into Europe. Schiebinger tells the remarkable story of Maria Sibylla Merian, one of the few European women to voyage for science in the eighteenth century. In a moving passage in her magnificent 1705 Metamorphosis insectorum Surinamensium, the German-born naturalist Merian recorded how the Indian and African slave populations in Surinam, then a Dutch colony, used the seeds of a plant she identified as the flos pavonis, literally ‘peacock flower’, as an abortifacient to abort their children so they would not become slaves like themselves. This book reveals how gender relations in Europe and its West Indian colonies influenced what European bioprospectors collected—and failed to collect—as they entered the rich knowledge traditions of the Caribbean. As Schiebinger tells, abortifacients were a body of knowledge that did not circulate freely between the West Indies and Europe. Trade winds of prevailing opinion impeded shiploads of New World abortifacients and knowledge of their use from ever reaching Europe. This book won the prize in Atlantic History from the American Historical Association in 2005, the Alf Andrew Heggoy Book Prize from the French Colonial Historical Society in 2005, and the J. Worth Estes Prize for the History of Pharmacology from the American Association for the History of Medicine in 2005. These prizes demonstrate her ability to win the admiration of scholars across a wide-variety of disciplines. Secret Cures of Slaves: People, Plants, and Medicine in the Eighteenth-Century Atlantic World (2017) From 1932 to 1972, 600 impoverished Alabamian African-American sharecroppers were exploited by the U.S. Public Health Service in its Tuskegee Syphilis Study (1932–1972). This book explores the eighteenth-century background of medical experimentation with humans, asking in particular if the large populations of enslaved people, concentrated on American plantations, were used as human guinea pigs. A major finding of Secret Cures of Slaves is that, in many instances, European physicians in the British and French West Indies did not—as might be expected—use enslaved people as guinea pigs.
