CONTAGIONISM IN HISTORY
Welcome to this website. I created this site to make my articles available to other Independent Scholars. I hope to add other materials relevant to the history of contagionism and contagious diseases.
The picture is a detail of a portrait by William Hogarth thought to be of his friend Dr. John Fothergill. As a member of the Society of Friends, Fothergill refused to sit for his portrait, so Hogarth probably painted him from memory.

Google NGram of the word "Contagion"
The first peak shown on this graph, in the 1650s appears to be dominated by the metaphoric use of contagion (e.g. the contagion of sin, the contagion of heresies) and to reflect an increase in religious and political tracts during the Interregnum; the second peak, about 1800, is due to medical controversies over whether acute diseases such as jail fever were contagious.

Anon. A New Discovery of the Nature of the Plague . . . Contrary to the Opinion of Dr. Meade, [sic] Dr. Browne, and others, who give for the First Causes of the Plague . . . Air, Diet, and Disease
(London: T. Bickerton and J. Wilford, n.d. preface dated Aug. 31, 1721
This very rare book is not, strictly speaking, a contagionist work. It attributed plague to "a subtle active poisonous Body or Insect, very minute ... living on and subsisting by the virulent Matter in the body ... the Air being no more to it, than it is to Birds. The author, who frequently refers to the similar views of Richard Bradley, suggests that the smaller insects are, the faster they multiply, explaining why plague kills its victims so quickly. He points out that inanimate particles can't move of their own accord and they become weakened, not increased in power, when they impart their qualities to another body. Despite Mead's theory that the plague consisted of small venomous particles, bodies could not absorb particles through the pores in the skin because the body constantly exhales through them. The fact that no epidemic had taken place in England for more than half a century despite many earthquakes, floods, storms, sieges and bad weather showed that these events did not cause the plague. Similarly, there were many starving and sick people who did not contract plague. In the second portion of this book, as if he had completely forgotten the argument he had just made, the author blames the bad air emanating from large, closely packed groups of people. He suggested that the existence of many prison galleys in Marseilles led to the epidemic there and suggested that the largest source for the problem in London was the presence of many prisons within the city. He called for the removal of criminals to prisons outside the city and for the release of debtors from debtors' prison. The vehemence of his discussion of the plight of London debtors suggests that this advice may have been self-interested, but it was probably sound advice nevertheless.
M.A.C.D. [?Robert Boyle] Systême d'un Medicin Anglois sur la Cause de Toutes Les Especes de Maladies, Avec Les Surprenantes Configurations Des differentes especes de petits Insectes, qu'on voit par le moyen d'un bon Microscope dan le Sang & dan les Urines des differens Malades, & même de tous ceux qui doivent le devenir Recueilli par M.A.C.D. (Paris: Alexis-Xavier-Rene Mesnier, 1726)
"The system of an English Doctor on the cause of all sorts of diseases with the surprising appearances of different species of small Insects, which can be seen by the means of a good Microscope in the Blood and in the Urine of different patients, and also in all those who will become ill"
This entertaining treatise, reported to be by a quack physician and juggler called Robert Boyle, Boile or Boil, claims to be a translation of the third part of a treatise entitled "Systems of an English Doctor, on the nature of God & of Souls, on the Generation of every thing, on the cause of all sorts of Maladies, and on their cure, collected and made intelligible... to everyone". The author explains that he has only translated the third part because the first part (on the nature of God) would be contrary to the revealed truth of our religion, the second (on generation) would wound the modesty of the chaste, and the fourth (on medicine) would not only make all men their own doctors but also all women.
The Google version, which is digitized from a copy in the University of Lausanne (2009) includes a sequel, "Suite du Systeme d'un Medicine Anglois, sur la Guerison des Maladies, par lequel sont indiquees les especes de Vegetaux & Mineraux, qui sont des Poisons infallibles pour tuer les differentes especes de petits Animaux, qui causent nos Maladies, Recueilli par M.A.C.D. (Paris, Mesnier: 1727)
"The sequel of the System of an English Doctor on the Cure of Illnesses, by which is indicated the sorts of Vegetables and Minerals which are unfailing poisons for kill the different species of small Animals which cause our diseases".
This attributes the earlier work to conversations the author had had with an English doctor, coming from Ispaham (Isfahan) who had been passing through Europe with the Persian Ambassador in 1715.
For the story of this work, see William Bulloch, History of Bacteriology (1938, Dover edn, New York: 1979), p. 32.
Benjamin Marten, A New Theory of Consumptions, More especially of a Phthisis or Consumption of the Lungs (London: 1720)
The first complete account of Contagium Vivum by an English author. The first edition appeared in 1720; a second ed. appeared in 1722.
E. H. Griffith, "The Germ Theory" Griffith reported that, as Charles Singer would later do, he was browsing in an antiquarian shop (this one was in Pike's Peak) when he stumbled on a copy of Marten's work and was transfixed. This article, from the American Microscopical Journal of 1891, was reprinted twice in other local medical publications, one in St. Louis and the other in Michigan. The author was presumably Ezra Hollace Griffith, a microscopist, inventor of the "Griffith Stand" and frequent contributor to the journal. Griffith wrote that "The germ theory of disease is generally supposed to be new, and I do not now recall any one who knows it was advocated prior to 25 years ago [i.e. c. 1865]."
This is a good example of one of those recurrent waves of collective amnesia that often overtook the medical profession.
Richard Mead, A Short Discourse Concerning Pestilential Contagion and the Methods to be Used to Prevent it London: Printed for Sam. Buckley in Amen-Corner and Ralph Smith at the Royal-Exchange, 1720.
There were nine editions; the last was in 1744. The book is dedicated to James Craggs, Secretary of State, who would soon become implicated in the scandal over the bursting of the South Sea Bubble. Craggs lost his son to smallpox in February, 1721 and died one month later of a stroke.

This interesting title, now on the Open Collections program on Contagion from the Countway Library at Harvard is accessible from an extremely annoying, slow and balky page viewer. If you can, download a .pdf and read from that. They should let Google Books provide it.

H[ector] Grasset, "La théorie parasitaire et la phthisie pulmonaire au XVIIIe Siècle", France Médicale (Nov. 17, 1899), translated by Thomas C. Minor as "The Parasitic Theory and Pulmonary Phthisis in the Eighteenth Century" Cincinnati Lancet-Clinic, n.s. 44 93: (Jan. 6, 1900), 22-26 and (Jan. 13, 1900), 43.
This is very helpful historical review of eighteenth-century contagionist works. Unfortunately, several proper nouns are misspelled in the Minor translation, making it harder to find the article through Google searches. As far as I know, 20th. century historians were unaware of this article. I have not been able to locate the original French, version.
William MacMichael, "A Brief Sketch of the Progress of Opinion on the Subject of Contagion; with some Remarks on Quarantine"
The URL points to the text provided by the Harvard University Library website for "Contagion: Historical Views of Diseases and Epidemics". This copy, which begins on p. 519 of an unnamed source (perhaps The Pamphleteer) appears to be the same as a work listed by Google Books as being published in London by John Murray in 1826, but the Google link does not provide a text. MacMichael wrote this work in an effort to refute the arguments of Charles MacLean who had called for an end to quarantines against Plague. In this short work MacMichael analyzes the views of several British authors about the contagiousness of several febrile diseases including smallpox and scarlet fever.

HISTORY OF MEDICINE PODCASTS/STREAMING AUDIO AND VIDEO
Several medical libraries and history of medicine institutions host history of medicine lectures periodically. They have begun to make these available as podcasts or streaming audio/video recordings. The technical quality is often poor--amounting to a recorder near the dais in a large auditorium when the lecture is given, but the lectures themselves are often wonderful. I don't know of any source that catalogs/indexes these by speaker or subject or even of any master list of these lectures but here are links to a few libraries that have announced the availability of audio/video records of this sort of event
