Editor's Notes
- (William Osler, founder of the Association of Physicians of Great Britain and Ireland) 12 July 1849 – 29 December 1919 William Osler was born in a remote part of Ontario known as Bond Head. He spent a year at Trinity College in Ontario before deciding on a career in medicine. He attended the Toronto Medical College for two years and in 1872 received his M.D. degree from McGill University in Montreal. Like many of his fellow physicians trained in Canada, Osler went abroad for postgraduate study. He studied in London, Berlin, and Vienna before returning to Canada in 1874 and joining the medical faculty at McGill. A year later he was promoted to professor. Osler was elected a fellow of the British Royal College of Physicians in 1883, one of only two Canadian fellows at that time. In 1884 he left Montreal for Philadelphia to become professor of clinical medicine at the University of Pennsylvania. John S. Billings recruited William Osler in 1888 to be physician-in-chief of the soon-to-open Johns Hopkins Hospital and professor of medicine at the planned school of medicine. Osler was the second appointed member of the original four medical faculty, following William H. Welch and preceding Howard A. Kelly and William S. Halsted. He revolutionized the medical curriculum of the United States and Canada, synthesizing the best of the English and German systems. Osler adapted the English system to egalitarian American principles by teaching all medical students at the bedside. He believed that students learned best by doing and clinical instruction should therefore begin with the patient and end with the patient. Books and lectures were supportive tools to this end. The same principles applied to the laboratory, and all students were expected to do some work in the bacteriology laboratory. Osler introduced the German postgraduate training system, instituting one year of general internship followed by several years of residency with increasing clinical responsibilities. William Osler’s book, The Principles and Practice of Medicine, first published in 1892, supported his imaginative new curriculum. It was based upon the advances in medical science of the previous fifty years and remained the standard text on clinical medicine for the next forty years. Osler, a superb diagnostician and clinician, was greatly esteemed by his peers in this country and abroad. In 1905 he accepted the Regius Professorship of Medicine at Oxford University, at the time the most prestigious medical appointment in the English-speaking world. He left Maryland with warm feelings for Hopkins knowing that his sixteen years spent had laid a solid foundation for the future of Hopkins medical education. The greater the ignorance the greater the dogmatism. The philosophies of one age have become the absurdities of the next, and the foolishness of yesterday has become the wisdom of tomorrow. The natural man has only two primal passions, to get and to beget. We can only instill principles, put the student in the right path, give him method, teach him how to study, and early to discern between essentials and non-essentials. We are here to add what we can to, not to get what we can from, Life. Humanity has but three great enemies: fever, famine, and war; of these by far the greatest, by far the most terrible, is fever. The master word [work]... is the open sesame to every portal, the great equalizer in the world, the true philosopher's stone which transmutes all the base metal of humanity into gold. My second fixed idea is the uselessness of men above sixty years of age, and the incalculable benefit it would be in commercial, political, and in professional life, if as a matter of course, men stopped work at this age. I have three personal ideals. One, to do the day's work well and not to bother about tomorrow...The second ideal has been to act the Golden Rule, as far as in me lay, toward my professional brethren and toward the patients committed to my care. And the third has been to cultivate such a measure of equanimity as would enable me to bear success with humility, the affection of my friends without pride, and to be ready when the day of sorrow and grief came to meet it with the courage befitting a man. Medicine is a science of uncertainty and an art of probability. Nothing in life is more wonderful than faith—the one great moving force wh ich we can neither weigh in the balance nor test in the crucible. No human being is constituted to know the truth, the whole truth, and nothing but the truth; and even the best of men must be content with fragments, with partial glimpses, never the full fruition. One of the first duties of the physician is to educate the masses not to take medicine. Soap and water and common sense are the best disinfectants. The best preparation for tomorrow is to do today's work superbly well. The desire to take medicine is perhaps the greatest feature which distinguishes man from animals. There are three classes of human beings: men, women and women physicians. There is no more difficult art to acquire than the art of observation, and for some men it is quite as difficult to record an observation in brief and plain language. If you listen carefully to the patient they will tell you the diagnosis. To have striven, to have made the effort, to have been true to certain ideals - this alone is worth the struggle. To study the phenomenon of disease without books is to sail an uncharted sea, while to study books without patients is not to go to sea at all. (He who studies medicine without books sails an uncharted sea, but he who studies medicine without patients does not go to sea at all.) Variability is the law of life, and as no two faces are the same, so no two bodies are alike, and no two individuals react alike and behave alike under the abnormal conditions which we know as disease. The trained nurse has become one of the great blessings of humanity, taking a place beside the physician and the priest. Live neither in the past nor in the future, but let each day's work absorb your entire energies, and satisfy your widest ambition.
