    Notes: Abstract Biologists and historians often present natural history and molecular biology as distinct, perhaps conflicting, fields in biological research. Such accounts, although supported by abundant evidence, overlook important areas of overlap between these areas. Focusing upon examples drawn particularly from systematics and molecular evolution, I argue that naturalists and molecular biologists often share questions, methods, and forms of explanation. Acknowledging these interdisciplinary efforts provides a more balanced account of the development of biology during the post-World War II era.

    Notes: Abstract Between 1946 and 1960, a new phenomenon emerged in the field of bacteriology. “Bacterial sex,” as it was called, revolutionized the study of genetics, largely by making available a whole new class of cheap, fast-growing, and easily manipulated organisms. But what was “bacterial sex?” How could single-celled organisms have “sex” or even be sexually differentiated? The technical language used in the scientific press – the public and inalienable face of 20th century science – to describe this apparently neuter organism was explicit: the cells “copulated,” had “intimate contract,” “conjugal unions,” and engaged in “ménage ã trois” relationships. And yet, to describe bacteria as sexually reproducing organisms, the definition of sex itself had to change. Despite manifold contradictions and the availability of alternative language, the notion of sexually active (even promiscuous) single-celled organisms has persisted, even into contemporary textbooks on cell biology and genetics. In this paper I examine the ways in which bacteria were brought into the genetic fold, sexualized, and given gender; I also consider the issues underlying the durability of “bacterial sex.”

    Notes: Abstract Investigators of animal behavior since the eighteenth century have sought to make their work integral to the enterprises of natural history and/or the life sciences. In their efforts to do so, they have frequently based their claims of authority on the advantages offered by the special places where they have conducted their research. The zoo, the laboratory, and the field have been major settings for animal behavior studies. The issue of the relative advantages of these different sites has been a persistent one in the history of animal behavior studies up to and including the work of the ethologists of the twentieth century.

    Notes: Abstract In the period 1875–1920, a debate about the generality and applicability of evolutionary theory to all organisms was motivated by work on unicellular ciliates like Paramecium because of their peculiar nuclear dualism and life cycles. The French cytologist Emile Maupas and the German zoologist August Weismann argued in the 1880s about the evolutionary origins and functions of sex (which in the ciliates is not linked to reproduction), and death (which appeared to be the inevitable fate of lineages denied sexual conjugation), an argument rooted in the question of whether the ciliates and their processes where homologous to other cellular organisms. In the beginning of the twentieth century, this question of homology came to be less important as the ciliates were used by the British protozoologist Clifford Dobell and the American zoologist Herbert Spencer Jennings to study evolutionary processes in general rather than problems of development and cytology. For them, homology mattered less than analogy. This story illustrates two partially distinct problems in evolutionary biology: first, the question of whether all living things have common features and origins; and second, whether their history and current nature can be described by identical mechanisms. Where Maupas (contra Weismann) made the ciliates qualitatively the same as all other organisms in order to create a cohesive evolutionary theory for biology, Jennings and Dobell made them qualitatively different in order to achieve the same end.

    Notes: Abstract In 1853, the young Thomas Henry Huxley published a long review of German cell theory in which he roundly criticized the basic tenets of the Schleiden-Schwann model of the cell. Although historians of cytology have dismissed Huxley’s criticism as based on an erroneous interpretation of cell physiology, the review is better understood as a contribution to embryology. “The Cell-theory” presents Huxley’s “epigenetic” interpretation of histological organization emerging from changes in the protoplasm to replace the “preformationist” cell theory of Schleiden and Schwann (as modified by Albert vonKölliker), which posited the nucleus as the seat of organic vitality. Huxley’s views influenced a number of British biologists, who continued to oppose German cell theory well into the twentieth century. Yet Huxley was pivotal in introducing the new German program of “scientific zoology” to Britain in the early 1850s,championing its empiricist methodology as a means to enact broad disciplinary and institutional reforms in British natural history.

    Notes: Abstract The post-Civil War American natural history craze spawned a new institution – the natural history dealer – that has failed to receive the historical attention it deserves. The individuals who created these enterprises simultaneously helped to promote and hoped to profit from the burgeoning interest in both scientific and popular specimen collecting. At a time when other employment and educational prospects in natural history were severely limited, hundreds of dealers across the nation provided encouragement, specimens, publication outlets, training opportunities, and jobs for naturalists of all motivations and levels of expertise. This paper explores the crucial role that specimen dealers played in the larger natural history community. After briefly examining the development of local taxidermy shops in the mid-nineteenth century, it then traces the history of four large natural history dealerships established in the United States during the latter half of the century: Ward's Natural History Establishment, Frank Blake Webster's Naturalists' Supply Depot, Southwick & Jencks' Natural History Store, and Frank H. Lattin & Co. By the early twentieth century, changing tastes in interior design, the growth of the Audubon movement, and the dramatic expansion of alternate training and job opportunities for naturalists led many specimen dealers either to shift their emphasis or to shut their doors.

    Notes: Abstract Bionomics was a research approach invented by British biological scientists in the late nineteenth century and adopted by the American entomologist and evolutionist Vernon Lyman Kellogg in the early twentieth century. Kellogg hoped to use bionomics, which was the controlled observation and experimentation of organisms within settings that approximated their natural environments, to overcome the percieved weaknesses in the Darwinian natural selection theory. To this end, he established abionomics laboratory at Stanford University, widely published results from his bionomic investigations, and encouraged other biological researchers to adopt bionomics.

    Notes: Abstract The general popularity of natural history in the eighteenth century is mirrored in the frequency and importance of the more than 4,500 articles on natural history in the Encyclopédie. The main contributors to natural history were Daubenton, Diderot, Jaucourt and d'Holbach, but some of the key animating principles derive from Buffon, who wrote nothing specifically for the Encyclopédie. Still, a number of articles reflect his thinking, especially his antipathy toward Linnaeus. There was in principle a natural tie between encyclopedism, with its emphasis on connected knowledge, and the task of natural historians who concentrated on the relationships among living forms. Both the encyclopedists and natural historians aimed at a sweeping overview of knowledge, and we see that Diderot's discussions of the encyclopedia were apparently informed by his reading of natural history. Most of the articles on natural history drew from traditional sources, but there are differences in emphasis and choice of subject, depending upon the author. Diderot's 300 contributions are often practical, interesting, and depend upon accounts from other parts of the world. Jaucourt, who wrote more articles on natural history than anyone else, followed in his footsteps. Daubenton's 900 articles reflected a more narrow, professional approach. His contributions concluded for the most part with Volume 8, and Jaucourt carried on almost single-handedly after that. While staking out traditional ground (description, taxonomy) and advancing newer theoretical views linked with Buffon, natural history in the Encyclopédie avoided almost completely the sentimentalism concerning nature that developed after Rousseau.
