The Department of the History of Medicine at Johns Hopkins is proud to introduce new online CME modules that provide a historical perspective on issues of relevance to clinical practice today. Our first module, which launched in January 2018, explores the social, political, and economic forces that continue to shape the dynamic boundaries of the medical profession. Medical professionalism is...
Pasteur realized the germs that had been left exposed to the air had been weakened. When the chickens were injected with the weakened germs they had developed immunity to the disease. Pasteur and his team went on to create a vaccine for anthrax by keeping anthrax germs heated to 42-43 degrees centigrade for 8 days. In 1882 they created a vaccine for rabies. A co-worker dried the spines of rabbits that had contracted the disease in glass jars. Pasteur tried giving a series of injections made from the dried spines to animals to test the remedy. Then, in 1885, Pasteur successfully used the vaccine on a boy who had been bitten by a rabid dog. Pasteur also invented a way of sterilizing liquids by heating them (called pasteurization). It was first used for wine (in 1864) and later for milk.

Established by Congress in 1959 as the nation's highest scientific honor, the National Medal of Science is a presidential award given to individuals "deserving of special recognition by reason of their outstanding contributions to knowledge in the physical, biological, mathematical or engineering sciences." In 1980, Congress expanded this recognition to include the social and behavioral sciences.
Unfortunately in the 17th century medicine was still handicapped by wrong ideas about the human body. Most doctors still thought that there were four fluids or 'humors' in the body, blood, phlegm, yellow bile and black bile. Illness resulted when you had too much of one humor. Nevertheless during the 17th century a more scientific approach to medicine emerged and some doctors began to question traditional ideas. Apart from Harvey the most famous English doctor of the 17th century was Thomas Sydenham (1624-1689). He is sometimes called the English Hippocrates because he emphasized the importance of carefully observing patients and their symptoms.
We revisit this important topic to gear up for the next Functional Forum – Evolution of Environmental Medicine from the Environmental Health Symposium. We will be connecting with more practitioners to discuss the importance of understanding where the major sources of toxicity come from and the ways to help your community of patients and clients to avoid these harmful toxins.
The First Viennese School of Medicine, 1750–1800, was led by the Dutchman Gerard van Swieten (1700–1772), who aimed to put medicine on new scientific foundations—promoting unprejudiced clinical observation, botanical and chemical research, and introducing simple but powerful remedies. When the Vienna General Hospital opened in 1784, it at once became the world's largest hospital and physicians acquired a facility that gradually developed into the most important research centre. Progress ended with the Napoleonic wars and the government shutdown in 1819 of all liberal journals and schools; this caused a general return to traditionalism and eclecticism in medicine.
In London, the crown allowed two hospitals to continue their charitable work, under nonreligious control of city officials. The convents were all shut down but Harkness finds that women—some of them former nuns—were part of a new system that delivered essential medical services to people outside their family. They were employed by parishes and hospitals, as well as by private families, and provided nursing care as well as some medical, pharmaceutical, and surgical services.
c.130 CE Birth of Galen, considered by many to be the most important contributor to medicine following Hippocrates. Born of Greek parents, Galen resides primarily in Rome where he is physician to the gladiators and personal physician to several emperors. He publishes some 500 treatises and is still respected for his contributions to anatomy, physiology, and pharmacology.
During the U.S. Civil War the Sanitary Commission collected enormous amounts of statistical data, and opened up the problems of storing information for fast access and mechanically searching for data patterns. The pioneer was John Shaw Billings (1838–1913). A senior surgeon in the war, Billings built the Library of the Surgeon General's Office (now the National Library of Medicine), the centerpiece of modern medical information systems. Billings figured out how to mechanically analyze medical and demographic data by turning facts into numbers and punching the numbers onto cardboard cards that could be sorted and counted by machine. The applications were developed by his assistant Herman Hollerith; Hollerith invented the punch card and counter-sorter system that dominated statistical data manipulation until the 1970s. Hollerith's company became International Business Machines (IBM) in 1911.
The development of modern neurology began in the 16th century in Italy and France with Niccolò Massa, Jean Fernel, Jacques Dubois and Andreas Vesalius. Vesalius described in detail the anatomy of the brain and other organs; he had little knowledge of the brain's function, thinking that it resided mainly in the ventricles. Over his lifetime he corrected over 200 of Galen's mistakes. Understanding of medical sciences and diagnosis improved, but with little direct benefit to health care. Few effective drugs existed, beyond opium and quinine. Folklore cures and potentially poisonous metal-based compounds were popular treatments. Independently from Ibn al-Nafis, Michael Servetus rediscovered the pulmonary circulation, but this discovery did not reach the public because it was written down for the first time in the "Manuscript of Paris" in 1546, and later published in the theological work which he paid with his life in 1553. Later this was perfected by Renaldus Columbus and Andrea Cesalpino. Later William Harvey correctly described the circulatory system. The most useful tomes in medicine used both by students and expert physicians were De Materia Medica and Pharmacopoeia.
During the 18th century the mentally ill were not regarded as 'truly' human. It was thought that they did not have human feelings. They were therefore confined in chains. People paid to visit asylums and see the insane as if they were animals in a zoo. However in 1793 a doctor called Philippe Pinel argued that the insane should be released and treated humanely. As an experiment he was allowed to release some patients. The experiment worked and attitudes to the insane began to change.
Mummified bodies provide direct evidence for ailments and their treatments. They have shown us that ancient Egyptians suffered from eye diseases, rheumatoid arthritis, bladder, kidney and gallstones, bilharzia, arterial disease, gout and appendicitis. The tree-bark splints on a 5,000 year old mummified arm show that fractures were splinted. Most bone fractures found archaeologically are healed, further proof of good medical care.
German physician Robert Koch, noting fellow German Ferdinand Cohn's report of a spore stage of a certain bacterial species, traced the life cycle of Davaine's bacteridia, identified spores, inoculated laboratory animals with them, and reproduced anthrax—a breakthrough for experimental pathology and germ theory of disease. Pasteur's group added ecological investigations confirming spores' role in the natural setting, while Koch published a landmark treatise in 1878 on the bacterial pathology of wounds. In 1881, Koch reported discovery of the "tubercle bacillus", cementing germ theory and Koch's acclaim.

Danny is a serial entrepreneur and has been involved in the online education space for more than a decade. We've been working very closely with Danny at the Evolution of Medicine to help us build out our online courses like the Practice Accelerator, the New Patient GPS, and the Membership Practice Builder.
After AD 400, the study and practice of medicine in the Western Roman Empire went into deep decline. Medical services were provided, especially for the poor, in the thousands of monastic hospitals that sprang up across Europe, but the care was rudimentary and mainly palliative. Most of the writings of Galen and Hippocrates were lost to the West, with the summaries and compendia of St. Isidore of Seville being the primary channel for transmitting Greek medical ideas. The Carolingian renaissance brought increased contact with Byzantium and a greater awareness of ancient medicine, but only with the twelfth-century renaissance and the new translations coming from Muslim and Jewish sources in Spain, and the fifteenth-century flood of resources after the fall of Constantinople did the West fully recover its acquaintance with classical antiquity.
The underlying principle of most medieval medicine was Galen's theory of humours. This was derived from the ancient medical works, and dominated all western medicine until the 19th century. The theory stated that within every individual there were four humours, or principal fluids—black bile, yellow bile, phlegm, and blood, these were produced by various organs in the body, and they had to be in balance for a person to remain healthy. Too much phlegm in the body, for example, caused lung problems; and the body tried to cough up the phlegm to restore a balance. The balance of humours in humans could be achieved by diet, medicines, and by blood-letting, using leeches. The four humours were also associated with the four seasons, black bile-autumn, yellow bile-summer, phlegm-winter and blood-spring.
