Much of the early history of developmental and physiological genetics in Germany remains to be written. Together with Carl Correns and Richard Goldschmidt, Alfred Kühn occupies a special place in this history. Trained as a zoologist in Freiburg im Breisgau, he set out to integrate physiology, development and genetics in a particular experimental system based on the flour moth Ephestia kühniella Zeller. This paper is meant to reconstruct the crucial steps in the experimental pathway that led Kühn and his collaborators at the University of Göttingen, and later at the Kaiser Wilhelm Institutes of Biology and Biochemistry in Berlin, to formulate, in their specific way, what later became known as the “one gene – one enzyme hypothesis.” Special attention will be given to the interaction of the different parts of Kühn's Ephestia-based project, which were rooted in different research traditions. The paper retraces how, roughly between 1925 and 1945, these elements came to form a mixed experimental set-up composed of genetic, embryological, physiological and, finally, biochemical constituents. Accordingly, emphasis is laid on the development of the terminology in which the results were cast, and how it reflected the hybrid state of an experimental system successively acquiring new epistemic layers. 相似文献

Developments in the history of human genetics are of interest to those who participated in them and also to historians of medicine and science. Individuals in these fields are increasingly concerned that the record of this history is being discarded. Based on a talk by two archivists which was presented at the Second International Workshop on Genetics, Medicine and History, this paper discusses the problems of selection and preservation and suggests methodologies and actions currently available which offer some practical solutions. Only by acting now in a co-ordinated approach of our disciplines will a history of human genetics survive. 相似文献

In 1919 the Animal Breeding Research Department was established in Edinburgh. This Department, later renamed the Institute of Animal Genetics, forged an international reputation, eventually becoming the centrepiece of a cluster of new genetics research units and institutions in Edinburgh after the Second World War. Yet despite its significance for institutionalising animal genetics research in the UK, the origins and development of the Department have not received as much scholarly attention as its importance warrants. This paper sheds new light on Edinburgh’s place in early British genetics by drawing upon recently catalogued archival sources including the papers of James Cossar Ewart, Regius Professor of Natural History at the University of Edinburgh between 1882 and 1927. Although presently a marginal figure in genetics historiography, Ewart established two sites for experimental animal breeding work between 1895 and 1911 and played a central role in the founding of Britain’s first genetics lectureship, also in 1911. These early efforts helped to secure government funding in 1913. However, a combination of the First World War, bureaucratic problems and Ewart’s personal ambitions delayed the creation of the Department and the appointment of its director by another six years. This paper charts the institutionalisation of animal breeding and genetics research in Edinburgh within the wider contexts of British genetics and agriculture in the early twentieth century. 相似文献

An international conference, “The Global Crisis of Malaria: Lessons of the Past and Future Prospects,” met at Yale University, November 7-9, 2008. The symposium was organized by Professor Frank Snowden and sponsored by the Provost’s office, the MacMillan Center, the Program in the History of Science and History of Medicine, and the Section of the History of Medicine at the Yale School of Medicine. It brought together experts on malaria from a variety of disciplines, countries, and experiences — physicians, research scientists, historians of medicine, public health officials, and representatives of several non-governmental organizations (NGOs). An underlying theme was that much could be gained from a big-picture examination across disciplinary frontiers of the contemporary public health problem caused by malaria. Particular features of the conference were its intense scrutiny of historical successes and failures in malaria control and its demonstration of the relevance of history to policy discussions in the field. 相似文献

Ernst Rüdin (1874–1952) was the founder of psychiatric genetics and was also a founder of the German racial hygiene movement. Throughout his long career he played a major role in promoting eugenic ideas and policies in Germany, including helping formulate the 1933 Nazi eugenic sterilization law and other governmental policies directed against the alleged carriers of genetic defects. In the 1940s Rüdin supported the killing of children and mental patients under a Nazi program euphemistically called “Euthanasia.” The authors document these crimes and discuss their implications, and also present translations of two publications Rüdin co-authored in 1938 showing his strong support for Hitler and his policies. The authors also document what they see as revisionist historical accounts by leading psychiatric genetic authors. They outline three categories of contemporary psychiatric genetic accounts of Rüdin and his work: (A) those who write about German psychiatric genetics in the Nazi period, but either fail to mention Rüdin at all, or cast him in a favorable light; (B) those who acknowledge that Rüdin helped promote eugenic sterilization and/or may have worked with the Nazis, but generally paint a positive picture of Rüdin’s research and fail to mention his participation in the “euthanasia” killing program; and (C) those who have written that Rüdin committed and supported unspeakable atrocities. The authors conclude by calling on the leaders of psychiatric genetics to produce a detailed and complete account of their field’s history, including all of the documented crimes committed by Rüdin and his associates. 相似文献

Sequencing of the human genome has ushered in a new era of biology. The technologies developed to facilitate the sequencing of the human genome are now being applied to the sequencing of other genomes. In 2004, a partnership was formed between Washington University School of Medicine Genome Sequencing Center's Outreach Program and Washington University Department of Biology Science Outreach to create a video tour depicting the processes involved in large-scale sequencing. "Sequencing a Genome: Inside the Washington University Genome Sequencing Center" is a tour of the laboratory that follows the steps in the sequencing pipeline, interspersed with animated explanations of the scientific procedures used at the facility. Accompanying interviews with the staff illustrate different entry levels for a career in genome science. This video project serves as an example of how research and academic institutions can provide teachers and students with access and exposure to innovative technologies at the forefront of biomedical research. Initial feedback on the video from undergraduate students, high school teachers, and high school students provides suggestions for use of this video in a classroom setting to supplement present curricula. 相似文献

The Kaiser Wilhelm Institute for Anthropology, Human Genetics and Eugenics in Berlin-Dahlem was the centre of scientific racism in Nazi Germany. Its bad history culminated in a research project to analyse the molecular basis of racial differences in the susceptibility to various infectious diseases such as tuberculosis. Josef Mengele, a former postdoc of the director of the institute, Otmar von Verschuer, collected blood samples and other material in Auschwitz from families and twins of Jews and Gypsies. The blood samples were analysed by Günther Hillmann in the Berlin laboratory of Nobel Prize winner Adolf Butenandt. Butenandt had just moved to Tübingen. The project was paid for by the Deutsche Forschungsgemeinschaft. Butenandt, Hillmann and von Verschuer made scientific careers in the Federal Republic. To the present day this past has not been acknowledged by the Max-Planck-Gesellschaft as part of its history. 相似文献

The Department of Cell Biology at the Yale University School of Medicine was established in 1983. It was preceded by the Section of Cell Biology, which was formed in 1973 when George E. Palade and collaborators came to Yale from the Rockefeller University. Cell Biology at Yale had its origins in the Department of Anatomy that existed from the beginning of classes at the Medical Institution of Yale College in 1813. This article reviews the history of the Department of Anatomy at Yale and its evolution into Cell Biology that began with the introduction of histology into the curriculum in the 1860s. The formation and development of the Section and Department of Cell Biology in the second half of the 20th century to the present time are described. Biographies and research activities of the chairs and key faculty in anatomy and cell biology are provided. 相似文献

The Wellcome Trust Centre for Human Genetics (WTCHG) was established in 1994 to undertake research into the genetic basis of common diseases. Since June 1999 the centre has been located in the Henry Wellcome Building of Genomic Medicine, University of Oxford. The scientific objective of the centre is to explore all aspects of the genetic susceptibility of disease including the localisation of genes involved in common diseases, characterization of the variants responsible for susceptibility, the understanding of how these DNA variants may contribute to risk of disease in the population and finally, the understanding of how such genetic factors contribute biologically to a disease process. The centre houses multidisciplinary research teams in human genetics, functional genomics, bioinformatics, statistical genetics and structural biology. 相似文献

This paper lays the groundwork for a theory of time allocation across the life course, based on the idea that strength and
skill vary as a function of age, and that return rates for different activities vary as a function of the combination of strength
and skills involved in performing those tasks. We apply the model to traditional human subsistence patterns. The model predicts
that young children engage most heavily in low-strength/low-skill activities, middle-aged adults in high-strength/high-skill
activities, and older adults in low-strength/high-skill activities. Tests among Machiguenga and Piro forager-horticulturalists
of southeastern Peru show that males and females focus on low-strength/low-skill tasks early in life (domestic tasks and several
forms of fishing), switch to higher-strength/higher-skill activities in their twenties and thirties (hunting, fishing, and
gardening for males; fishing and gardening for females), and shift focus to high-skill activities late in life (manufacture/repair,
food processing).

From the 1980s to the late 1990s, Germany was among the forerunners for the critical debate on biotechnology and genetic engineering. In 1995, co-ordinated by the Centre of Technology in Baden-Württemberg, a joint venture research project was established. The project followed an interdisciplinary perspective and included research on attitudes, the social and cognitive embedding of attitudes, and argumentation patterns as well as studies on the communication of genetic engineering in the media. The structure and rationale of this joint research project is described in the first article. 相似文献
