Twentieth Century: Arro Wsmith and the Doctor's Dilemma Medical History, 1988, 32: 314-332. IMMUNOLOGY AND LITERATURE IN THE EARLY TWENTIETH CENTURY: ARRO WSMITH AND THE DOCTOR'S DILEMMA by ILANA LOWY* Scientific research is at the centre of two important literary works published in the early twentieth century: George Bernard Shaw's play The doctor's dilemma (1906), and Sinclair Lewis's novel, Arrowsmith (1925). Both deal with medical science, and in both the hero is an immunologist (or, in the terminology of the period, a specialist in the science of immunity). But the images of immunology in Shaw's play and in Lewis's book are very different. Moreover, the same real-life scientist, the flamboyant Sir Almroth Wright and the same immunological theory, Wright's opsonin theory, appear in both works, but in diametrically opposed roles. Wright is the barely disguised prototype of Shaw's hero, the scientist Sir Colenso Ridgeon, and Shaw represents the opsonin theory as the most advanced form ofscientific knowledge. The name ofWright is seldom mentioned explicitly in Arrowsmith but his opsonin theory is the incarnation ofthe false theories ofimmunity fought by Max Gottlieb, the exemplary scientist in the novel. Whywas the young science ofimmunology honoured by placementat thecentre oftwo major literary works? Why was the study ofimmunity the right occupation for a literary hero in the early twentieth century? And what is the basis ofthe differences in Shaw's and Lewis's presentations of this discipline, differences made explicit by their opposed evaluations ofthe same scientist and the same theory?Answering these questions can help us not only to obtain some new insights into these literary works, but also to understand the evolution ofimmunology in the context ofthe rapid but by no means unproblematic penetration of scientific ideas into early twentieth-century medicine. I The scientist who plays such a different role in the two literary works, Sir Almroth Wright (1861-1947), was one of the pioneers of prophylactic vaccination in human beings. He was described by his biographers as an impressive figure, both physically and intellectually. Before turning to medical research, Wright studied literature and law and for the rest of his life he kept up a vast array of extra-scientific interests, publishing besides numerous scientific works, articles, pamphlets and books on such topics as philosophy, social criticism, and women's suffrage, which he opposed.

He was also a born fighter, bringing his various professional struggles not only before his colleagues, but the lay public as well.' Wright fought for many years to get official recognition for the heat-killed, anti-typhoid vaccine he developed in 1897-98.2 When in 1902 he became the head of the departments of bacteriology and pathology at St Mary's Hospital in London, he found a new field of battle, the "vaccine therapy" which kept him busy for the rest of his life. While studying the phagocytosis (ingestion) of pathogenic bacteria by white blood cells, Wright noticed that the ingestion and destruction ofbacteria by phagocytic cells was facilitated by the presence ofspecific antibodies in the serum. The destruction of bacteria by white blood cells in the presence of a specific antiserum had been described first by Denys and Leclef, then studied by Marchand and Mennes;3 but Wright, who applied the staining methods developed by Leishman to the study of bacterial phagocytosis, was the first to quantify this phenomenon, point to its potential therapeutic importance and give it a name-'opsonisation'.4 In his studies, he stressed the importance of both serum antibodies and of phagocytic cells in fighting invading bacteria. He was thus able to reconcile, at least partially, two opposing views concerning the nature of immunity: that of the "cellular school" (mostly French), led by Elie Metchnikoff, who claimed that immune phenomena were mediated by phagocytic cells only; and that ofthe "humoral school" (mostly German), led by Paul Ehrlich and Emil von Behring, who claimed that only the specific antibodies in the serum were of importance in immune phenomena.5 Wright claimed that the discovery of opsonisation not only shed new light on the phenomena of immunization, but also opened a new era in the therapy of infectious 1 Biographies of Wright were written by Leonard Colebrook, Almroth Wright, London, William Heinemann Medical Books, 1954; and by Zachary Cope, Almroth Wright, the founder of modern vaccino-therapy, London, Nelson, 1966. Several chapters ofGwyn Macfarlane's biography ofSir Alexander Fleming deal with Wright's personality and describe in detail the atmosphere in his laboratory at St. Mary's Hospital in London: Alexander Fleming: the man and the myth, Oxford University Press, 1984. Wright's scientific achievements are described by H. A. Lechevalier and M. Solotorowski in Three centuries of microbiology, New York, San Francisco, and Toronto, McGraw Hill, 1965; and a detailed critical analysis ofthe practical value ofhis discoveries for medicine has been made by W. D. Foster in his History ofmedical bacteriology and immunology, London, William Heinemann Medical Books, 1979. 2 Wright claimed that careful analysis ofthe incidence oftyphoid among vaccinated and non-vaccinated soldiers during the Boer War clearly demonstrated the effectiveness of his vaccine. Not everyone was as convinced. Wright's statistical data, based on rather unreliable army records, concerned relatively few cases. The validity ofhis statistical methods was contested by the statistician Karl Pearson. A. E. Wright, 'On the results which have been obtained by anti-typhoid inoculation', Lancet, 1902, Hi: 651; K.

He attempted to cure many bacterial diseases, particularly chronic and recurrent ones, by using "therapeutic inoculation", i.e. immunization with small doses ofa vaccine prepared with the bacterium that induced the disease. The rationale behind this treatment was that the vaccine would reinforce the body's natural defences by stimulating the formation of "opsonising antibodies", and accelerate the elimination ofthe invading bacteria by phagocytic cells. But, Wright added, the "vaccine therapy" would work only if administered at specific critical moments in the evolution of the individual patient's immune response. These critical moments could be found by measuring the patients "opsonin index", i.e. the capacity of the phagocytic cells of a given patient at a given moment to ingest specific pathogenic bacteria. However, according to Wright, measurement of the "opsonic index" was a very delicate and complicated operation that could be completed successfully only by such highly qualified and well-trained pathologists as the members of his own group at St Mary's Hospital.6 Many patients were drawn to Wright's laboratory, attracted by the possibility of a cure for chronic bacterial diseases. His research unit, aptly rebaptized the "Inoculation Department", expanded rapidly and became financially self-supporting. Wright's success was not, however, universally welcomed. Some doctors contested the efficacy of this treatment and the general validity of Wright's propositions. They nicknamed him "Sir Almost Wright" and "Sir Almost Wrong". Wright responded with virulent public attacks on the members ofthe British medical profession, calling them ignorant, incompetent, complacent and guilty of deceiving their patients.7 He vigorously criticized lazy physicians who did not bother to learn the complexities of infection phenomena but waited for new therapies which "would achieve the marvellous with little labour".8 Nevertheless, the principle of vaccine therapy was adopted by a significant portion of the medical

    Celestial Twins Voluntarily Cooperation and the Celestial Twinning Bond The Children’s Saviors: Emil Behring and Paul Ehrlich The Sign: Pisces Keyword: I believe Paul Ehrlich Emil Behring lthough today there is no precise definition of “twinning bond,” nobody denies its existence. This strong emotional or even telepathic bond is described in Aresearch of identical twins reared apart. The relationship between such twins is usually much more intense than that between unrelated people. They may share a closeness that would be hard to match in most other relationships, or they may compete with each other in a struggle to be first. Goering and Rosenberg seemed to belong to the latter category, their instinctive wish to be first dictated to them the desire to get rid of each other, yet even so, in the Nuremberg trials they did not blame each other. Was it just by chance that a kind of celestial twinning bond was observed in the previous stories, or is there a special system of relationships characteristic of celestial twins? Are celestial twins compelled to be in constant competition or do their joined efforts release unusually strong powers as are ascribed by mythology to some biological twins? Some of the answers to these intriguing questions I found in the comparative life stories of the Nobel Prize winners in Medicine, Emil von Behring and Paul Ehrlich. These celestial twins were, like Halem and Stauffenberg, born in Pisces. Though from birth separated by geography, religion and genes, they both found their life mission in Berlin, where both worked at the Institute of Hygiene.

  • Paul De Kruif, American Science Writer on Malaria: a Case Study
    Verhave MWJ 2011, 2:1 Paul de Kruif, American science writer on malaria: a case study Verhave, J.P. Honorary research fellow at the Van Raalte Institute, Hope College, Holland, Michigan [email protected] Abstract From 1926 onward, science writer Paul de Kruif has popularized the history of great discoveries in the science of diseases, malaria among them. During the thirties he focused on abuses and neglects of medical care and pointed to new developments, e.g., the treatment of syphilis with heat, rather than with malaria therapy. He conveyed his messages in popular magazines, using a romantic style and explicit language that was unheard of. He promoted new drugs, like Atabrine for endemic malaria and for the military engaged in (sub-) tropical war zones. Medical authorities were unhappy that his message about Atabrine was so dramatic, raising unwarranted hope of eradication. By the end of the Second World War, however, the usefulness of Atabrine was recognized. In my research I consulted original sources: letters, articles and books of De Kruif, as well as contemporary scientific publications; recent books on malaria history helped to design the historiography. Paul de Kruif’s dealing with various malaria topics is presented as a case study of science writing. Modern malaria research requires skilled journalists: they can excite public interest about problems in distant parts of the tropical world and work to raise funds. Journalists should also push for the translation of (bio-) medical progress to applicable tools in malaria control. 1 Introduction the state of health of the people.

  • How American Comic Books Celebrated Heroes of Medicine in the 1940S
    148 bert hansen Medical History for the Masses: How American Comic Books Celebrated Heroes of Medicine in the 1940s BERT HANSEN summary: When comic books rose to mass popularity in the early 1940s, one segment of the industry specialized in “true adventures,” with stories about real people from the past and the present—in contrast to competing books that offered fantasy, science fiction, superheroes, detectives and crime, funny people, or funny animals. This study examines the figures from both medical history and twentieth-century medicine who were portrayed as heroes and role models in these comic books: first, to call attention to this very popular, if unknown, genre of medical history, and second, to illustrate how medical history was used at that time to popularize scientific and medical ideas, to celebrate the achievements of medical research, to encourage medical science as a career choice, and to show medicine as a humane and noble enterprise. The study explains how these medical history stories were situated in American popular culture more gener- ally, and how the graphic power of comic books successfully conveyed both values and information while also telling a good story. Attention to this colorful genre of popular medical history enriches our picture of the mid-twentieth- century public’s enthusiasm for medical progress. keywords: cartoons, comic books, medical history, medical heroes, popular culture, Golden Age, scientific method, medical research Presentations of this research were made at the 73rd Annual Meeting of the American Association for the History of Medicine, Bethesda, Md., on 21 May 2000, and at Queens University, Kingston, Ont., on 10 October 2000.

    Medical History, 2010, 54: 529–536 Clifford Dobell and the Making of CORE Metadata, citation and similar papers at core.ac.uk Provided by PubMed Central Paul de Kruif’s Microbe Hunters JAN PETER VERHAVE* While researching the activities of Paul de Kruif, an American microbiologist and medical science journalist,1 I came across some previously unknown correspondence of interest for the history of malaria research and of the history of medicine generally. It sheds new light on the origin of De Kruif’s book Microbe hunters and more particularly on his description of the discovery of the transmission of malaria parasites by mosquitoes. The letters were written by Clifford Dobell, a British protozoologist, to his friend Paul de Kruif.2 They triggered a little-known sequel to the priority battle between the two discoverers of the transmission of malaria parasites, Ronald Ross and Giovanni Battista Grassi. Colleagues and Friends Before earning his living from writing, Paul de Kruif (1890–1971) had carried out front- line bacteriological research at Michigan University, as a US medical corps officer during the First World War in France, and thereafter at the Rockefeller Institute, New York. He chose, however, to become a writer and, specifically, a science journalist. One of the reasons was his dissatisfaction with the unscientific and arrogant attitude of the American medical profession in general. It resulted in a rather critical book Our medicine men (1922) that cost him his position as a researcher. The next episode in his career was the collaboration with Sinclair Lewis on Arrowsmith (1925), a medical novel.

  • Early History of Microbiology and Microbiological Methods
    1 EARLY HISTORY OF MICROBIOLOGY AND MICROBIOLOGICAL METHODS Robert F. Guardino AAI Development Services Wilmington, N.C. USA INTRODUCTION The original title of this chapter was to be “History of Microbiological Methods.” This would seem to indicate that inquisitive minds were consciously attempting to develop new methods for a new field of science. Or perhaps they had a “for profit” motive as if they were working for a company driving them towards new markets or to increase their portfolio of patents from which to draw royalties. This could not be further from the truth. Rather, the history of microbiology is a story of some common folk and other rather peculiar individuals, janitors and hobbyists, amateur lens grinders and chemists, physicians and botanists, housewives and laboratory “slaves” with a quest for discovery. These explorers were sometimes driven by chance or curiosity, and sometimes by a problem for which no one had an answer. And, they were driven sometimes by pride or self-interest. But then there were those altruistic ones driven by the pure compassion for suffering humanity. With the topic being rather broad, and the space being somewhat limited, the scope had to be narrowed so this chapter has mutated into one that attempts to expose the minds behind the discoveries; 1 www.pda.org/bookstore 2 Encyclopedia of Rapid Microbiological Methods discoveries that necessitated the rather simple, though not always obvious, techniques that made revealing the world of microorganisms possible. The story that unfolds is first a history of events and phenomenon for which there was no understanding or explanation, followed by observations for which there was no obvious application, to the eventual association of cause and effect, on to a full blown field of inquiry.
