This essay outlines the various analytical frameworks related to the history of race science that contribute to a "Latin" intellectual culture and tradition. In addition to defining Latinity as applied to the history of science, this article examines the troubled relationship between Latin American history and histories of science characterized as global. Similarly, it explores intellectual linkages across the Global South regarding racial mixture and the legacy of colonialism. It concludes by considering how a Latin perspective can illuminate the continued hegemony of ideas and scientific practices originating in North America and northern Europe. [ABSTRACT FROM AUTHOR]

This introductory essay frames our special issue by discussing how attention to the history of research integrity and fraud can stimulate new historical and methodological insights of broader import to historians of science. [ABSTRACT FROM AUTHOR]

This essay examines the relationship between slavery and plant knowledge for cultivational activities and medicinal purposes on Isle de France (Mauritius) in the second half of the eighteenth century. It builds on recent scholarship to argue for the significance of slaves in the acquisition of plant material and related knowledge in pharmaceutical, acclimatization, and private gardens on the French colonial island. I highlight the degree to which French colonial officials relied on slaves' ethnobotanical knowledge but neglected to include such information in their published works. Rather than seeking to explore the status of such knowledge within European frameworks of natural history as an endpoint of knowledge production, this essay calls upon us to think about the plant knowledge that slaves possessed for its practical implementations in the local island context. Both female and male slaves' plant-based knowledge enriched – even initiated – practices of cultivation and preparation techniques of plants for nourishment and medicinal uses. Here, cultivational knowledge and skills determined a slave's hierarchical rank. As the case of the slave gardener Rama and his family reveals, plant knowledge sometimes offered slaves opportunities for social mobility and, even though on extremely rare occasions, enabled them to become legally free.

In the early twentieth century, the United States Department of Agriculture (USDA) funded international expeditions with the aim of finding plant specimens for introduction into the agricultural landscape and the new experimental projects in hybridization. One such agricultural explorer, noted for his eponymous lemon, was Frank Nicholas Meyer, an immigrant from the Netherlands whose expeditions in Asia have brought to the United States celebrated fruit and toxic weeds. Neither professional botanists nor farmers, plant hunters like Meyer worked by taking advantage of historical allegiances to academic programs, while leaning on the authority of their newer national institutions. In addition to plants, through photographs that transposed Chinese landscapes to U.S. environmental counterparts, Meyer contributed to the imagination of the agricultural promise of the American West. The era of these plant explorers has ended but their material trace remains in a variety of spaces and modes of existence that have hitherto been disregarded. Reading Meyer's letters shows the authority and discipline behind his transformation from gardener's apprentice to professional plant collector. I argue that photographs and plants are understudied material traces that enable historians to re-examine the means by which credit was received, given, and exchanged. By drawing together these traces, I chart the continued importance of exploration and collection in the twentieth century and show the epistemic continuity between nineteenth-century natural history and twentieth-century experimental science.

This essay challenges the dominance of the spherical earth model in fifteenth- and early-sixteenth-century Western European thought. It examines parallel strains of Latin and vernacular writing that cast doubt on the existence of the southern hemisphere. Three factors shaped the alternate accounts of the earth as a plane and disk put forward by these sources: (1) the unsettling effects of maritime expansion on scientific thought; (2) the revival of interest in early Christian criticism of the spherical earth; and (3) a rigid empirical stance toward entities too large to observe in their entirety, including the earth. Criticism of the spherical earth model faded in the decades after Magellan’s crew returned from circuiting the earth in 1522. [ABSTRACT FROM AUTHOR]
