Johann Friedrich Meckel, Jr. as founder of scientific teratology

n the occasion of the 150th anniversary of his death, the scientific work of the famous German anatomist Johann Friedrich Meckel (1781 to 1833) in Halle is appreciated. The Younger Meckel is counted to the most outstanding figures in the history of anatomy and medicine in the first third of 19th century. According to his founded knowledges in the normal, comparative, and pathologic anatomy and embryology he was able to give a scientific argument of malformations first of all in the history of medicine and biology. The edition of Meckel's Handbook of Pathologic Anatomy (in German language; 1st vol. 1812) is the birth of scientific teratology. Through his contributions to teratology Meckel directly participated in the raising of general pathology and pathologic anatomy to scientific disciplines. Meckel's interceding for C. F. Wolff's theory of epigenesis, not at last by translation of Wolff's paper "De formatione intestinorum" (1768 to 1769) into the German language, accelerated the development of the general and special embryology during the 19th century. In the contemporary medicine the succeeding eponyms are reminding of the imposing German physician and anatomist: the Meckel's diverticulum of ileum (1809), the Meckel's cartilage of the mandibular arch (1820) and the so-called Meckel syndrome (1822).     

Biology and war--American biology and international science

The German-born American scientist Jacques Loeb (1859-1924) was one of the most important promoters of experimental biology around 1900. He was best known for his physico-chemical explanations of psychological processes and his biotechnological approach to artificial parthenogenesis. At the start of the First World War, Loeb was deeply troubled by the deterioration of the international scientific community and the growing alienation of his German and American colleagues. The aim of this paper is to examine Jacques Loeb's activities aimed at advancing scientific internationalism before, during, and after the war. Loeb, for example, tried to negotiate the publication of German authors in American journals during the war, at a time when this was categorically rejected by publishers. Immediately after the war, he tried to create a specific system aimed at disseminating scientific literature and funding selected European colleagues, in order to overcome what he considered reactionary and hegemonic forces within German scientific institutions. His correspondence with eminent scientists from all over the world (amongst them Albert Einstein, Richard Goldschmidt, Otto Meyerhof, Otto Warburg, Paul Ehrlich, Wolfgang Ostwald, Wilhelm Roux, and Ross Harrison) will serve as a source for the analysis. Special emphasis will be placed on the question how Jacques Loeb integrated epistemology, his particular world view, and his social commitment into the workings of his own life and how he tried to extend his scientific goal of controlling biological systems to the sphere of international science.     

Styles of scientific reasoning: Adolf Remane (1898–1976) and the German evolutionary synthesis

Adolf Remane is widely considered to have been one of the most influential German zoologists of the 20th Century, yet Ernst Mayr persistently characterized him as an idealistic morphologist, that is, a typologist unable to understand population genetics or indeed Darwinian theory. This stands in sharp contrast to Mayr's praise for Bernhard Rensch as one of the most important German contributors to the Modern Synthesis of evolutionary theory. Remane's style of scientific reasoning is analysed in his writings on microsystematics, ecology, comparative morphology and phylogenetics and found to be highly consistent throughout these varied fields of research, while differing fundamentally from the eminently statistical foundations of both population genetics and natural selection theory that were embraced by Mayr. A comparative analysis of Rensch's understanding of science in general, and biology in particular, shows him to share core values with Remane, both authors rooted in the Mandarin tradition of the German professoriate. Biographical and socio‐political factors appear to have influenced Mayr's contrasting perception of Remane and Rensch, one that would influence later biologists and historians of science.     

The specificity of medical facts: the case of diabetology

The fact that Ludwik Fleck drew his inspiration from medicine has been largely overlooked, with the exception of a few scholars. Although Fleck considered his ideas applicable to all sciences, he always insisted on the specificity of medicine. To illustrate the usefulness of Fleck’s concepts for the history of medicine, three main ideas developed by Fleck are applied to the historical study of diabetes mellitus (DM): first, that different and often divergent pictures of disease coexist within a given culture; second, that scientific ideas circulate between ‘esoteric’ and ‘exoteric’ circles; and third, that scientific concepts are often incommensurable. The author also suggests that Fleck’s epistemology, like other scholars’, is loaded with ethical and political consequences. However, the link between an ‘open’ epistemology and political or ethical questions is more explicit in Georges Canguilhem’s pioneering work on the normal and the pathological (1943). Indeed, Canguilhem and Fleck’s conceptions of disease have much in common, so that we can use Canguilhem’s work to bring out the hidden ethical and political issues in Fleck’s work.     

Evolutionary Morphology in Belgium

In historical literature, Edouard van Beneden (1846–1910) is mostly remembered for his cytological discoveries. Less well known, however, is that he also introduced evolutionary morphology – and indeed evolutionary theory as such – in the Belgian academic world. The introduction of this research programme cannot be understood without taking both the international and the national context into account. It was clearly the German example of the Jena University that inspired van Beneden in his research interests. The actual launch of evolutionary morphology at his University of Liège was, however, also connected with the dynamic of Belgian university reforms and the local rationale of creating a research “school.” Thanks to his networks, his mastering of the rhetoric of the “new” biology, his low ideological profile and his capitalising on the new academic élan in late-19th century Belgium, van Beneden managed to turn his programme into a local success from the 1870s onwards. Two decades later, however, the conceptual underpinnings of evolutionary morphology came under attack and the “Van Beneden School” lost much of its vitality. Despite this, van Beneden’s evolutionary morphology was prototypical for the research that was to come. He was one of the first scientific heavyweights in Belgium to turn the university laboratory into a centre of scientific practice and the hub of a research school.     

H. G. Bronn and the History of Nature

The German paleontologist H. G. Bronn is best remembered for his 1860 translation and critique of Darwin’s Origin of Species, and for supposedly twisting Darwinian evolution into conformity with German idealistic morphology. This analysis of Bronn’s writings shows, however, that far from being mired in an outmoded idealism that confined organic change to predetermined developmental pathways, Bronn had worked throughout the 1840s and 1850s on a new, historical approach to life. He had been moving from the study of plant and animal forms in the abstract towards placing them into geological and biogeographical context, analyzing patterns of progress and adaptation, explaining species diversity and individual variation, and applying biological insights to practical problems such as artificial breeding. Even though Bronn never fully accepted the idea of species transformation, he saw Darwin’s theory as a bold new move toward his own goal of establishing a comprehensive, historical science of life, and he presented it as such in his translation and commentary. Thus Darwin’s ideas gained a quick and generally favorable hearing in Germany not because of their easy assimilability into an older tradition, but because of their appeal to the innovative Bronn.     

Early twentieth-century paleontological research of Freidrich von Huene: contributions to the knowledge of Late Cretaceous vertebrates of Central Brazil

Friedrich von Huene’s important scientific research on tetrapod fossils from Central Brazil has received little attention, even though it represents a significant contribution to early studies of vertebrate paleontology in the country including the first discoveries of dinosaur fossils in Brazil. von Huene described five reptile taxa in two papers published in important German scientific journals and used these specimens to make paleogeographic inferences regarding the Cretaceous of the Southern Hemisphere. von Huene warrants recognition as the first specialist to describe in detail the fossil reptile fauna of Central Brazil, which was made possible only by his network of contacts with important and influential naturalists of the cities of Rio de Janeiro and São Paulo.     

The Gentleman and the Rogue: The Collaboration Between Charles Darwin and Carl Vogt

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, since, on closer investigation, Darwin not only gave serious consideration to engaging Vogt as the German translator of two of his books, albeit ultimately rejecting him, but he also collaborated with Vogt on the French editions of his works. In this paper we argue that this was not because Darwin was unaware of Vogt’s personality and blunt writing style; rather, Darwin seems to have decided that the benefits he would gain from their association would clearly outweigh the risk of offending some of his readers: in working with Vogt, who was not only a knowledgeable scientist but also an avowed adherent of Darwinism, Darwin could be assured of the scientific quality of the translation and of an edition that would not distort his central concepts – both of which were by no means matters of course in 19th-century translations of scientific works.     

Luigi Galvani's path to animal electricity

In spite of the historical importance of the research that, in the second half of the 18th century, led Luigi Galvani (1737-1798) to lay down the foundation of modern electrophysiology, his scientific personality is largely misrepresented in science history and in popular imagery. He is still considered as a pioneer that by chance incurred some surprising experimental observations and was incapable of pursuing his research in a coherent way. In contrast with these views, Galvani was a high-standard scientist who succeeded, with the strength of experimental science, in demonstrating, in animals, electricity in a condition of disequilibrium between the interior and the exterior of excitable fibres. This electricity, called 'animal electricity', was deemed responsible for nerve conduction. By studying the scientific endeavours of Galvani, through his published and unpublished material, and by situating them in the historical context of the physiology of the Enlightenment, this paper attempts to trace the elusive and complex path that led Galvani to his extraordinary discovery.     

The Lenoir thesis revisited: Blumenbach and Kant

Timothy Lenoir launched the historical study of German life science at the end of the 18th century with the claim that J. F. Blumenbach’s approach was shaped by his reception of the philosophy of Immanuel Kant: a ‘teleomechanism’ that adopted a strictly ‘regulative’ approach to the character of organisms. It now appears that Lenoir was wrong about Blumenbach’s understanding of Kant, for Blumenbach’s Bildungstrieb entailed an actual empirical claim. Moreover, he had worked out the decisive contours of his theory and he had exerted his maximal influence on the so-called ‘Göttingen School’ before 1795, when Lenoir posits the main influence of Kant’s thought took hold. This has crucial significance for the historical reconstruction of the German life sciences in the period. The Lenoir thesis can no longer serve as the point of departure for that reconstruction.     

A bridge-builder: Wolf-Ernst Reif and the Darwinisation of German paleontology

Wolf-Ernst Reif was an outstanding German paleontologist, who, along with his empirical studies (biomechanics, functional and constructional morphology, etc.), paid significant attention to theoretical issues and the history of his discipline. Reif was a bridge-builder, skillfully synthesising history, theory and empirical studies within German-language paleontology. This paper briefly discusses sophisticated relationships between German paleontology and Darwinism based on the historical studies of Wolf-Ernst Reif. German paleontology did not fully embrace Darwinism until the 1970s. There are several reasons for this. First, alternative evolutionary theories (saltationism, neo-Lamarckism, orthogenesis) occupied a significant segment of the theoretical landscape in the German life sciences. Second, typological thinking persisted in German paleontology after the Second World War. Third, German paleontologists were relatively uninterested in discussing mechanisms of evolution, concentrating instead on reconstructing phylogenetic history.     

IsSchindewolf’s “Grundfragen der Paläontologie” still worth reading? An apologetic evaluation of his work

Roughly five years ago O.H. Schindewolf’s book “Grundfragender Paläontologie” was first published in English by the University of Chicago Press, about fifty years after the original German edition. Thus, for the first time a considerable number of English-speaking palaeontologists became acquainted with the author’s ideas of the evolutionary process. Inevitably, numerous book reviews followed, introducing “the new publication’. The predominant tenor is characterized by titels like “Magnificent wrongheadedness” or “Wonderfully, gloriously wrong”. By referring to recent results in developmental genetics and population ecology it is shown that Schindewolf’s ideas concerning the progress of evolution must by no means be interpreted simply as a product of a self reverential, wrongheaded spirit, preformed by the atmosphere of German romanticism. Truly, his ideas can be understood as the result of a scientific imagination which was not preoccupied by neo-Darwinian paradigms and was ahead of the biological knowledge of his time.     

W. K. Brooks's role in the history of American biology

Conclusion The results of this study indicate that the reputation of W. K. Brooks was aided significantly by historical circumstances. The first of these factors was the unique historical role of Johns Hopkins University in American graduate education. The second was the impact of European experimentalism on American biologists and the consequent increase of experimentation in this country.Johns Hopkins, as an institution, greatly aided in the selection, nurture, and placement of Brooks's students. To these institutional forces, Brooks did add direction toward marine biology and facilities for marine research. Also, his teaching methods—which were reinforced by his own natural quietness and his poor health—did encourage self-reliance: Brooks simply could not dominate over the day-to-day activities of his students.The impact of European experimentalism was largely responsible for giving American biologists new approaches to problems which were beginning to assume major importance in biology. Several of Brooks's students, notably E. B. Wilson, T. H. Morgan, and Ross Harrison, were involved in this transfer of approaches and problems to America. In addition, a large number were influenced by working at the Marine Biological Laboratory at Woods Hole, where many of these new approaches were being used—in some cases for the first time, in this country. Both of these historical circumstances detract from Brooks's personal importance as an influential and directing force.That Brooks allowed his students to pursue their own research with comparative freedom is indisputable. Perhaps this is the criterion for an outstanding teacher. But the fact remains that none of his best students followed Brooks's own line of investigation or his own method of research. It is less important here to evaluate Brooks as a teacher than to understand his influence on the direction of biological thought in the twentieth century. This study suggests that his influence was less important in terms of setting a direction for research than has previously been believed. What it is apparent that Brooks accomplished was the setting forth of biological topics in a larger context through his insistence on the relevance of philosophy to scientific research. How much this directly influenced his students, especially those outstanding individuals who later made important advances, is difficult to determine. This paper has tried to show that, in terms of available evidence, Brooks does not seem to have had the profound influence on early twentieth-century biology that some historians have claimed.     

Emil Starkenstein--one of the most important personalities of European continental pharmacology in the period between the two world wars

Emil Starkenstein (1884-1942), professor of pharmacology at the German Medical Faculty of Charles University in Prague, was not only an experimental pharmacologist, but also the pioneer of clinical pharmacology. During the World War I (1914-1918) he took advantage of his knowledge of experimental pharmacology for the new approaches to the treatment of bacillary dysentery, cholera and of epidemic typhus fever. In 1918 he published the article "Clinical Pharmacology--Theory and Praxis at the Patient's Bedside", in which he defined the main task of clinical pharmacology as the implementation and verification of experimental pharmacology achievements in clinical therapy. During the period 1921-1933, his scientific interests involved namely analgesic combinations, seasickness therapy and pharmacology of iron. He published more than 240 scientific articles and three textbooks. Emil Starkenstein died on November 6, 1942 as a victim of Holocaust. Starkenstein s collection of more than 20,000 reprints of scientific studies, which has been deposited recently in the Archives of Charles University in Prague is very valuable.     

Paradigm change in evolutionary microbiology

Thomas Kuhn had little to say about scientific change in biological science, and biologists are ambivalent about how applicable his framework is for their disciplines. We apply Kuhn's account of paradigm change to evolutionary microbiology, where key Darwinian tenets are being challenged by two decades of findings from molecular phylogenetics. The chief culprit is lateral gene transfer, which undermines the role of vertical descent and the representation of evolutionary history as a tree of life. To assess Kuhn's relevance to this controversy, we add a social analysis of the scientists involved to the historical and philosophical debates. We conclude that while Kuhn's account may capture aspects of the pattern (or outcome) of an episode of scientific change, he has little to say about how the process of generating new understandings is occurring in evolutionary microbiology. Once Kuhn's application is limited to that of an initial investigative probe into how scientific problem-solving occurs, his disciplinary scope becomes broader.
