Beschriften, Wiederfinden und Reaktivieren: Die Rolle von Objektträgeretiketten im Auffindsystem am Beispiel von Alzheimers Auguste-D.-Präparaten

Labeling, Recovering and Reactivating: The Role of Labels on Microscope Slides in the Finding System on the Basis of Alzheimer’s Auguste D. Preparations. This study discusses the role of labels in the process of the reactivation (Rheinberger) of preparations. Labels on slides together with corresponding lists on cards or sheets build what is here called a specific finding system. In the sciences of the archive (Daston) the disciplinary memory together with such a finding system are the basis to the ability of the sciences today to reactivate preparations from the beginning of the last century as it occurs with the Auguste D. preparations. The case of Alzheimer’s micropreparations of brain parts of Auguste D. – the case that he used to show that hers was a specific brain disease unknown before – serves to describe Alzheimer’s writing on the labels. It is compared to slides and labels prepared by other medical researchers between the 1890s and 1920s and the respective finding systems. Being an epistemologicum, micropreparations, as they are data, in their hybrid status of both image and material in one, cross the boundaries between icon and index. This is proven by the reactivation of Auguste D. micropreparations in molecular biological studies over 100 years after their production.

„Sacra à Deo in corde discenda, natura ex natura.“ Die Observationes Johann Christian Senckenbergs als medico-theologische Aufzeichnungspraktik

“Sacra à Deo in corde discenda, natura ex natura.” Johann Christian Senckenberg’s Observationes as a Medico-Theological Writing Method. In his early diaries, the pietist physician Johann Christian Senckenberg has taken down large amounts of observation data which mostly concentrated on his own body and soul. Earlier research has mistaken his diligent self-observation for hypochondria and unworldliness, especially since the author had never endeavoured to analyze and publish his work. The article shows that both his writing practice and his reluctance to process and share its results are due to his deeply religious and firmly anti-rationalist conviction. The main purpose of his journal keeping was the attainment of religious self-knowledge and professional self-perfection. Scientific publications he considered to be hypothetical and dogmatic, be it in theology or medicine; moreover, their authors were often enough driven by their self-love and desire for fame. In his eyes, the only godly way of knowledge acquisition was the humble, diligent and minute study of divine creation according to the Hippocratic method. The most immediate and reliable way of achieving true wisdom, however, was the observation of God’s work within one’s own body and mind, which were subject to the effects of God’s grace and punishment as well as to atmospheric, environmental and dietetic circumstances.
