  • draughtsmen Botanists and nature constructing eighteenth century botanical illustrations
    Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2006
    Co-Authors: Karin Nickelsen
    Abstract:

    Abstract At first glance botanical illustrations of the eighteenth century might be interpreted as being naturalistic portraits of living plants. A more detailed investigation, however, reveals that the pictures were meant to communicate typical features of plant species in the way of a model. To this end, Botanists of the period gave botanical draughtsmen specialist training; copying earlier examples and standardised motives from drawing books was a common part of this training. The practice of copying elements of previously published drawings and integrating them into new pictures was also widespread. However, only carefully selected elements were taken over, and even these were improved in terms of their correctness and appropriateness to the new context. This procedure was a strategy that eighteenth-century Botanists used so that they would present an illustration that met their own requirements more satisfactorily than existing depictions. From this perspective, botanical illustrations can serve as historical sources on the working practices of eighteenth-century Botanists and draughtsmen, which are usually not mentioned in textual sources.

  • the challenge of colour eighteenth century Botanists and the hand colouring of illustrations
    Annals of Science, 2006
    Co-Authors: Karin Nickelsen
    Abstract:

    Summary Colourful plant images are often taken as the icon of natural history illustration. However, so far, little attention has been paid to the question of how this beautiful colouring was achieved. At a case study of the eighteenth-century Nuremberg doctor and botanist, Christoph Jacob Trew, the process of how illustrations were hand-coloured, who was involved in this work, and how the colouring was supervised and evaluated is reconstructed, mostly based on Trew's correspondence with the engraver and publisher of his books, Johann Jacob Haid in Augsburg. Furthermore, the question of standardizing colours, their uses and their recipes is discussed at two examples of the same time period: the colour charts of the Bauer brothers, arguably the most renowned botanical draughtsmen of the period, and the colour tables by the Regensburg naturalist, Jacob Christian Schaeffer. Hand-colouring botanical illustrations, it is argued, was far from a straightforward task but confronted Botanists and their employees w...

  • Herbarium specimens reveal the exchange network of British and Irish Botanists, 1856–1932
    New Journal of Botany, 2020
    Co-Authors: Quentin Groom, C. O’reilly, T Humphrey
    Abstract:

    AbstractThe labels on herbarium specimens hold information on the plant collected, but also on the botanist. Recent digitisation allows these data to be used for many types of investigation, including study of the Botanists themselves. As a proof of concept, we reconstructed prosopographical networks of botanical exchange that existed in Britain and Ireland in the nineteenth and twentieth century and investigate the nature of these networks and their actors. Data from British Herbaria digitised on Herbaria@home were used to create network diagrams from the names of collectors, determiners, communicators and curators mentioned on herbarium specimens collected from 1856 to 1932. Data from herbarium specimens credibly reconstructed botanical exchange networks. These networks provided metrics on the actors in botanical exchange and can be used to quantify the role of different categories of actor. The botanical networks of the late nineteenth and early twentieth century were shown to be highly connected and d...

  • Botanists and their childhood memories an underutilized expert source in ethnobotanical research
    Botanical Journal of the Linnean Society, 2012
    Co-Authors: łukasz łuczaj, Monika Kujawska
    Abstract:

    Botanists are an overlooked group of informants in ethnobotanical studies. The aim of this study was to assess their potential as sources of original ethnobotanical information. Wild food plants remembered by Polish Botanists from their childhood were freelisted by 71 Botanists. The results were compared with several ethnobotanical studies: three from the 21st century and one from the mid-20th century. The Botanists listed 123 species (mean of 9.3 species per individual). Although the average number of personal freelists was slightly lower for Botanists than for local key informants in two of the other studies (11 and 13, respectively), the total list of species was longer than in any other Polish ethnobotanical study. Two of the ethnobotanical studies supplied richer material on past famine plants, whereas the Botanists mentioned many alien plants and plants from urban habitats not mentioned in the ethnographical study. It can be concluded that Botanists are possibly the best source of information for studies of contemporary or new uses of plants, but are inadequate for uses that are dying out. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 168, 334–343.
