What are cells? How are they related to each other and to the organism as a whole? These questions have exercised biology since Schleiden and Schwann (1838–1839) first proposed cells as the key units of structure and function of all living things. But how do we try to understand them? Through new technologies like the achromatic microscope and the electron microscope. But just as importantly, through the metaphors our culture has made available to biologists in different periods and places. These (...) two new volumes provide interesting history and philosophy of the development of cell biology. Reynolds surveys the field's changing conceptual structure by examining the varied panoply of changing metaphors used to conceptualize and explain cells – from cells as empty boxes, as building blocks, to individual organisms, to chemical factories, and through many succeeding metaphors up to one with great currency today: cells as social creatures in communication with others in their community. There is some of this approach in theVisionsedited collection as well. But this collection also includes rich material on the technologies used to visualize cells and their dialectical relationship with the epistemology of the emerging distinct discipline of cell biology. This volume centres on, but is not limited to, ‘reflections inspired by [E.V.] Cowdry's [1924 volume]General Cytology’; it benefits from a conference on the Cowdry volume as well as a 2011 Marine Biological Lab/Arizona State University workshop on the history of cell biology.

Morphogenesis is one of the fundamental processes of developing life. Gastrulation, especially, marks a period of major translocations and bustling rearrangements of cells that give rise to the three germ layers. It was also one of the earliest fields in biology where cell movement and behaviour in living specimens were investigated. This article examines scientific attempts to understand gastrulation from the point of view of cells in motion. It argues that the study of morphogenesis in the twentieth century faced a (...) major dilemma, both epistemological and pictorial: representing form and understanding movement are mutually exclusive, as are understanding form and representing movement. The article follows various ways of modelling, imaging, and simulating gastrular processes, from the early twentieth century to present-day systems biology. The first section examines the tactile modelling of shape changes, the second cell cinematography, mainly the pioneering work of the German embryologists Friedrich Kopsch and Ernst Ludwig Gräper in the 1920s but also a series of classic, yet not widely known, studies of the 1960s. The third section deals with the changes that computer simulation and live-cell imaging introduced to the modelling of shape change and the study of cell movement at the turn of the twenty-first century. Although live-cell imaging promises to experiment upon and represent the living body simultaneously, I argue that the new visuals are an obstacle rather than a solution to the puzzle of understanding cell motion.

ZusammenfassungWurde die Geschichte der Filmdigitalisierung jemals in Fragen der Beweis- und Wissensproduktion einbezogen? Die gerade stattfindende Digitalisierung von vielen Tausend Filmen des ehemaligen Instituts für den Wissenschaftlichen Film (IWF) gibt Anlass, über die Provenienz und Wiederverwendung von Filmbildern nachzudenken als auch über die Art und Weise, in der sie behaupten, wissenschaftliche (oder in diesem Fall historische) Evidenz zu produzieren. In den Jahren von 1956 bis etwa 1960 initiierte der deutsche Sozialdemokrat, Historiker und Filmemacher Friedrich „Fritz“ Terveen Filmreihen, die mit vorgefundenem (...) Filmmaterial Hochschulstudent*innen über Zeitgeschichte aufklären sollten. Die erste kleine Filmreihe darunter warLuftschifffahrt in Deutschland, die vier kleine Filme mit gefundenem Filmmaterial über Zeppelinflüge umfasste, von denen die frühesten Bilder aus der Zeit um 1904 und die letzten aus dem Jahr 1937 stammen und die „Hindenburg-Katastrophe“ zeigen. In diesem Artikel soll gezeigt werden, wie Terveen die politische Landschaft des Geschichtsunterrichts in der neu gegründeten Bundesrepublik Deutschland zu gestalten suchte, indem er erstens danach strebte, ein bundesweites Bildarchiv mit historischen Filmdokumenten einzurichten und zweitens die politische Bildung einer neuen Generation junger Deutscher mithilfe des bewegten Bildes verbessern wollte.

This introduction outlines the threefold contribution that this Focus section on research film offers. First, it introduces the vast collection of films from the former Institute for Scientific Film (Institut für den Wissenschaftlichen Film [IWF]), arguably the most ambitious endeavor ever undertaken to manage the distribution, production, and archiving of research films. At the same time, the institute’s questionable roots in the National Socialist education system and in war research are addressed. Second, the introduction points out that the Focus section (...) enters largely uncharted terrain in the history of research films. Third, it argues that a focus on the multiple reuses of research films, as this section attempts, not only suits the medium specificity of film but helps us to map the aesthetic, intermedial, and cultural-political practices of disseminating knowledge. In this vein, the organizers asked established scholars working on film and science to share with us a short story of a reused research film. Scott Curtis, Vinzenz Hediger, Anja Laukötter, and Hanna Rose Shell responded. Their contributions can be found in the supplementary materials to the online edition. (shrink)

ArgumentThis paper arrives at a normative position regarding the relevance of Henri Bergson's philosophy to historical enquiry. It does so via experimental historical analysis of the adaptation of cinematographic devices to physiological investigation. Bergson's philosophy accorded well with a mode of physiological psychology in which claims relating to mental and physiological existence interacted. Notably however, cinematograph-centered experimentation by British physiologists including Charles Scott Sherrington, as well as German-trained psychologists such as Hugo Münsterberg and Max Wertheimer, contributed to a cordoning-off of (...) psychological from physiological questioning during the early twentieth century. Bergson invested in a mode of intellectual practice in which psychological claims had direct relevance to the interpretation of physiological nature. The in-part cinematograph-inspired breakdown of this mode had significance for subsequent interpretations of his philosophy. It is suggested that this experimental particularization of Bergson's contentions indicates that any adaptation of his thought for historical enquiry must be disciplinarily specific. (shrink)
