    Physicochemical Biology and Knowledge Transfer: The Study of the Mechanism of Photosynthesis Between the Two World Wars.Kärin Nickelsen - forthcoming - Journal of the History of Biology:1-29.
    In the first decades of the twentieth century, the process of photosynthesis was still a mystery: Plant scientists were able to measure what entered and left a plant, but little was known about the intermediate biochemical and biophysical processes that took place. This state of affairs started to change between the two world wars, when a number of young scientists in Europe and the United States, all of whom identified with the methods and goals of physicochemical biology, selected photosynthesis as (...)

  4. The Construction of a Scientific Model: Otto Warburg and the Building Block Strategy.Kärin Nickelsen - 2009 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 40 (2):73-86.
    In the years 1919 to 1923, Otto Warburg published four papers that were to revolutionise the field of photosynthesis. In these articles, he introduced a number of new techniques to measure the rate of photosynthesis, put forward a new model of the mechanism and added a completely new perspective to the topic by attempting to establish the process’s efficiency in terms of the light quantum requirement. In this paper I trace the roots of Warburg’s series of contributions to photosynthesis research (...)

    New perspectives in the history of twentieth-century life sciences: historical, historiographical and epistemological themes.Robert Meunier & Kärin Nickelsen - 2018 - History and Philosophy of the Life Sciences 40 (1):19.
    The history of twentieth-century life sciences is not exactly a new topic. However, in view of the increasingly rapid development of the life sciences themselves over the past decades, some of the well-established narratives are worth revisiting. Taking stock of where we stand on these issues was the aim of a conference in 2015, entitled “Perspectives for the History of Life Sciences”. The papers in this topical collection are based on work presented and discussed at and around this meeting. Just (...)

    Discovery of Causal Mechanisms: Oxidative Phosphorylation and the Calvin–Benson Cycle.Raphael Scholl & Kärin Nickelsen - 2015 - History and Philosophy of the Life Sciences 37 (2):180-209.
    We investigate the context of discovery of two significant achievements of twentieth century biochemistry: the chemiosmotic mechanism of oxidative phosphorylation and the dark reaction of photosynthesis. The pursuit of these problems involved discovery strategies such as the transfer, recombination and reversal of previous causal and mechanistic knowledge in biochemistry. We study the operation and scope of these strategies by careful historical analysis, reaching a number of systematic conclusions: even basic strategies can illuminate “hard cases” of scientific discovery that go far (...)

    In Pursuit of Formaldehyde: Causally Explanatory Models and Falsification.Kärin Nickelsen & Gerd Graßhoff - 2011 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 42 (3):297-305.
    Falsification no longer is the cornerstone of philosophy of science; but it still looms widely that scientists ought to drop an explanatory hypothesis in view of negative results. We shall argue that, to the contrary, negative empirical results are unable to disqualify causally explanatory hypotheses—not because of the shielding effect of auxiliary assumptions but because of the fact that the causal irrelevance of a factor cannot empirically be established. This perspective is elaborated at a case study taken from the history (...)

    The Organism Strikes Back: Chlorella Algae and Their Impact on Photosynthesis Research, 1920s–1960s.Kärin Nickelsen - 2017 - History and Philosophy of the Life Sciences 39 (2).
    Historians and philosophers of twentieth-century life sciences have demonstrated that the choice of experimental organism can profoundly influence research fields, in ways that sometimes undermined the scientists’ original intentions. The present paper aims to enrich and broaden the scope of this literature by analysing the career of unicellular green algae of the genus Chlorella. They were introduced for the study of photosynthesis in 1919 by the German cell physiologist Otto H. Warburg, and they became the favourite research objects in this (...)

    The Challenge of Colour: Eighteenth-Century Botanists and the Hand-Colouring of Illustrations.Kärin Nickelsen - 2006 - Annals of Science 63 (1):3-23.
    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 (...)

    The Gentleman and the Rogue: The Collaboration Between Charles Darwin and Carl Vogt.Martin Amrein & Kärin Nickelsen - 2008 - Journal of the History of Biology 41 (2):237-266.
    This paper investigates the relationship between the eminent 19th-century naturalists Charles Darwin and Carl Vogt. On two separate occasions, Vogt asked Darwin for permission to translate some of the latter’s books into German, and in both cases Darwin refused. It has generally been assumed that Darwin turned down Vogt as a translator because of the latter’s reputation as a radical libertine who was extremely outspoken in his defence of scientific materialism and atheism. However, this explanation does not fit the facts, (...)

    Draughtsmen, Botanists and Nature: Constructing Eighteenth-Century Botanical Illustrations.Kärin Nickelsen - 2006 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 37 (1):1-25.
    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 (...)

  24. Ein Botaniker in der Papiergeschichte: Offene und geschlossene Kooperationen in den Wissenschaften um 1900.Kärin Nickelsen & Josephine Musil-Gutsch - 2020 - NTM Zeitschrift für Geschichte der Wissenschaften, Technik und Medizin 28 (1):1-33.
    ZusammenfassungDie Studie analysiert die Dynamik wissenschaftlicher Kooperation zwischen Natur- und Geisteswissenschaften an einem Beispiel aus der historischen Papierforschung in Wien um 1900. Im Mittelpunkt steht der Wiener Pflanzenphysiologe Julius Wiesner, der ab 1884 mittelalterliche Papiermanuskripte unter dem Mikroskop prüfte. Dies erfolgte in produktiver Zusammenarbeit mit Paläographen, Archäologen und Orientalisten. Der Aufsatz untersucht, warum dies gelang und wie die Zusammenarbeit sich entwickelte. Wir unterscheiden dabei zwei Formen der Kooperation: Während Wiesner anfangs nur reaktiv zuarbeitete, in einer „geschlossenen Kooperation“, trat er später (...)

    ZusammenfassungDie Erforschung der Antarktis galt um 1900 als eine der letzten großen Herausforderungen im Zuge der Erschließung der Welt. Viele Nationen beteiligten sich daran, darunter das deutsche Kaiserreich. So fanden im Jahrzehnt vor dem Ersten Weltkrieg auch zwei deutsche Antarktisexpeditionen statt: von 1901 bis 1903 unter der Leitung von Erich von Drygalski und in den Jahren 1911/12 unter der Leitung Wilhelm Filchners. Die Forschung hat das Verhältnis zwischen den Unternehmen der verschiedenen Nationen bislang oftmals mit einem Fokus entweder auf Wettbewerb (...)
