Abstract: This paper concerns recent official attempts to place science in Denmark within the context of a cultural canon. Based on differentiation between Mode 1 and 2 knowledge production, the paper points out that such attempts are highly contextualised and contingent on their different modes of application. Consequent- ly, they entangle scientific expertise with other social skills and qualifications. Like science museums and science centres, they are a means of dealing with science in the public agora, i.e. the public sphere in which negotiations, mediations, consulta- tions and contestations regarding science increasingly take place. Analysing the am- biguities and uncertainties associated with the recent official placing of science wit- hin an overall cultural canon for Denmark, this paper concludes that even though the agora embodies antagonistic forms of interaction, it might also lead the way to producing socially robust knowledge about science.

  • Johannes Fibiger
    J OHANNES F I B I G E R Investigations on Spiroptera carcinoma and the experimental induction of cancer Nobel Lecture, December 12, 1927 Ladies and Gentlemen. Now that it is my honour to address the Swedish Society of Medicine, I should like to begin by expressing the debt of gratitude I owe to this Society. In 1913, some six months after I had published my first work on Spiroptera carcinoma, the Swedish Society of Medicine did me the honour of making me its member. This was the first recognition of this kind which came to me after the appearance of my work, and I would like to mention again today, here in the home of the Society, the great pleasure which I felt then and which I still recall with sincere gratitude. Before I go on to relate the principal results of my investigations on Spirop- tera carcinoma and the experimental induction of cancer, I would like to be allowed to offer the Nobel Foundation and the Staff of Professors of the Caroline Medio-Surgical Institute my most sincere and humble thanks for the great honour they have done me by finding my experiments worthy of the Nobel Prize in Physiology or Medicine. It is possible to trace back attempts at supplementing clinical and anatom- ical studies of cancer by means of experimental work on the disease’s origins, development and dissemination in the organism over a great number of years; not only the first, primitive experiments made over 150 years ago, but many more recent ones met with only negative results up to a short time ago.

In 1896 he engaged C J S Thompson to "research history of medicine and collect objects and books".' That marked the beginnings ofthe priceless collections now housed in the London Wellcome Library. Many of the objects there, books as well as works ofart, have been subjected to scrutiny by scholars and younger generations of students over the years; but parts of the iconographic collections are less well known, among them a series ofwatercolours, drawings, etc. ofentomological specimens and diseased patients, as well as caricatures of friends and colleagues, all showing the professional versatility and expertise of the artist, A J E Terzi. Terzi and other contemporaries might have deserved mention in the discussion which followed C P Snow's (1905-1980) Rede Lecture on 'The Two Cultures' in 1959.2 Snow's interest in his subject had grown from interdisciplinary discussions and table talk in Cambridge common rooms; stripped to their essentials, the underlying ideas called for closer political and educational understanding of, and co-operation between, "new" scientific knowledge and the humanities.

  • Questions of Quality: the Danish State Serum Institute, Thorvald Madsen and Biological Standardisation
    Questions of quality: The Danish State Serum Institute, Thorvald Madsen and Biological Standardisation Anne Hardy Published in Christoph Gradmann and Jonathan Simon eds, Evaluating and Standardizing Therapeutic Agents, 1890-1950 (Basingstoke: Palgrave MacMillan, 2010): 139-152. The opening of the Danish State Serum Institute in Copenhagen on 9 September 1902 was a festive occasion, attended by renowned figures from the wider bacteriological community including the German scientists Paul Ehrlich, Carl Weigert, and Julius Morgenroth, future Nobel prize-winner Svante Arrhenius from Sweden, Ole Malm and Armauer Hansen from Norway, and William Bulloch and German Sims Woodhead from England.1 Established as a national resource for the production of diphtheria antitoxin, the DSSI was from its inception concerned to deliver a quality product at a minimum price, and to link pharmaceutical production with research into, and further development of, biological products. In the course of the twentieth century, the institute acquired an international reputation for the quality of its products and its cutting edge research, and, in the 1920s, achieved international authority as the League of Nations Health Commission’s central laboratory for the preservation and distribution of all standard sera and bacterial products.2 The rise of the DSSI to international prominence came about through a combination of factors, personal, scientific and political , but above all, perhaps, from its early association with questions of quality in the production of the new generation biological medicines, of which diphtheria anti toxin was the first to emerge. Diphtheria and the Development of the Danish State Serum Institute The creation of the DSSI was largely due to the energy and determination of Carl Julius Salomonsen (1847-1924), the ‘father of danish bacteriology’,3 for Danish medical culture at that period was largely traditional with a focus on hospital medicine and general practice, rather than on research, let alone bacteriology.

  • Tion to True Malignant Tumors; with Some Remarks on Cancer Age
    ON SPIROPTERA CARCINOMATA AND THEIR RELA- TION TO TRUE MALIGNANT TUMORS; WITH SOME REMARKS ON CANCER AGE JOHANNES FIBIGER From the Anatomo-Pathological Institute of the University of Copenhagen Received for publication, July 25, 1919 In this Journal (1918, iii, 227) Bullock and Rohdenburg have criticized some reports published during the last years, concerning the experimental production of malignant tumors (Fibiger, Yamagiwa and Ichikawa) and tumor-like formations (Stahr). Bullock and Rohdenburg emphasize that An analysis of the several reports mentioned reveals a number of assertions common to each, which are at variance with the recognized laws of malignant tumor growth, while, at the same time, it brings out points which cast a certain amount of doubt upon the authors’ interpretation of their results. In the following I shall reply to Bullock and Rohdenburg’s criticism, though only in so far as it concerns the investigations on Spiroptera carcinoma communicated by me. I can so much the less avoid occupying myself with the assertions of these authors as their untenability seems to some extent to be due to an insufficient acquaintance with or a misapprehension of the details of my investigations of 1913 and 1914 (14). My most recently concluded investigations (&11), which corroborate the results of the former, were not published until after the appearance of the authors’ paper and so could not be known to them. Bullock and Rohdenburg base part of their criticism on a comparison between the result of my investigations on Spiroptera carcinoma and the result of investigations carried out by them- 367 368 JOHANNES FIBIGER selves on the effect of mechanical, chemical, or mechanico- chemical irritants’ on the stomach of the rat.

But the discovery of helminths as cancer-causing agents took wrong turns and marks an inglorious chapter in the history of science. The carcinogenicity of worms, vindicating Rudolf Virchow’s reiztheorie (irritation theory) of cancer origin, was glorified in the scien- tific forefront by Johannes Fibiger in the 1910s. Discovery of a new nematode, which he proudly named Spiroptera carcinoma, and his subsequent demonstration that the parasite could induce stomach cancer in rats, earned Fibiger a retrospec- tive Nobel Prize in Physiology or Medicine in 1926, and a lasting fame. But not in an appealing way. His achievement did not withstand the test of time.
