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.

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
