As recently as 2001, however, a Harveian Orator at the Royal College of Physicians spoke as though this discipline and ‘medicine in the tropics’ were one and the same. He concentrated on: malaria, snake bite and rabies, and concluded:2 In the 350 years of its history, this is the fi rst Harveian Oration to be devoted to Tropical Medicine; I hope that this is a sign that my speciality has at last [now that the formal disci- pline is in steep decline] been accepted into the mainstream of medicine in this country. Those who have worked for long in warm climates will, however, recognize that ‘medicine in the tropics’ has existed since time immemorial, and that it should be clearly demarcated from the rise and fall of the formal discipline. ix x PREFACE FIGURE A Queen Victoria (1819–1901) (reproduced courtesy of The Wellcome Library, London). Lloyd and Coulter, in their classic text Medicine and the Navy 1200–1900, have admirably summarized the difference between the two:3 For the historian of medicine, the fact that Naval Surgeons [before the development of the formal specialty] had more experience of tropical diseases [my italics] than any other branch of the profession … as Sir Patrick Manson recognized when he founded that dis- cipline in England. It cannot be pretended that they made much use of their experience because, for the most part, they were not outstanding members of their profession. None the less, they were by no means more backward than their colleagues on land before the days when the germ theory of disease replaced the atmospheric or climatorial pathology which prevailed up to the last decade of the [nineteenth] century. Whatever new advances were made in medical practice (and they were not numerous before the days of Lister and Pasteur) they were adopted in the [Naval] service with commendable promptness. PREFACE xi Thus, experience in the Caribbean, Africa and the ‘jewel in the Crown’ – India4 – pre-dated the development of the formal discipline, as did the practice of medi- cine in the West African Squadron. But even before this, much information on the diagnosis and management of disease acquired in tropical countries had been gathered over many centuries. Andrew Balfour (1873–1931)5 recognized this when he recalled, in his Presidential Address to the Royal Society of Tropical Medicine and Hygiene in 1925:6 There is in one sense no such thing as tropical medicine … many of the most erudite writ- ings of Hippocrates are concerned with maladies which now-a-days are chiefl y encoun- tered under tropical or sub-tropical conditions. An anonymous contributor to the British Medical Journal for 1913, summariz- ing the position a century before this, wrote:7 The study of tropical diseases [my italics] was obviously in its infancy in 1813; but there were indications that British medical men in India and in the West Indies were beginning to turn their attention to it, being forced to it indeed by the mortality from such maladies which was making itself felt in the troops stationed abroad and among the sailors manning the Indiamen and the fi ghting frigates of the time. There were no such schools of tropical medicine in those days such as are to be seen now; but there was already a clear indica- tion of the necessity which was to be laid upon Great Britain of the later nineteenth and of the earlier twentieth centuries to send forth of the best of her medical sons to discover the cause of Malta fever, to unravel the problem of sleeping sickness, and to learn to slay many another scourge existing in these tropical countries over which she has been placed as ruler, and for which she has already paid a price in blood. Thus, before development of the formal discipline, much of the practice of ‘med- icine in the tropics’ fell under the heading of hygiene, defi ned by the Oxford English Dictionary as:8 That department of knowledge or practice which relates to the maintenance of health; a system of principles or rules for preserving or promoting health; sanitary science. The development of the ‘formal discipline’, which focused largely on teach- ing the medical offi cers of numerous British colonies situated in warm climates about the ‘exotic’ diseases which the Western practitioner knew little or noth- ing about, has with some justifi cation been branded colonial medicine by some medical historians; Patrick Manson (1844–1922; see Chapter 3) was clearly the founding father of the discipline. According to G C Low (1872–1952; Chapter 8), an important but grossly under-recognized pioneer of the discipline, it was estab- lished during a 20-year period, 1894–1914.9 It is also crucially important to appreciate that ‘medicine in the tropics’ encompasses not only the ‘exotic’ infections (which have enormous geographi- cal variations, e.g.
