William Osler

William Osler is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand William Osler rather than just read about it. In short: Sir William Osler, 1st Baronet (; July 12, 1849 – December 29, 1919) was a Canadian physician and one of the "Big Four" founding professors of Johns Hopkins Hospital. Osler created the first residency program for specialty training of physicians.

Key takeaways

  • William Osler belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect William Osler to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of William Osler from memory before moving on to harder problems.

Reference excerpt

Sir William Osler, 1st Baronet (; July 12, 1849 – December 29, 1919) was a Canadian physician and one of the "Big Four" founding professors of Johns Hopkins Hospital. Osler created the first residency program for specialty training of physicians. He has frequently been described as the Father of Modern Medicine and one of the "greatest diagnosticians ever to wield a stethoscope". In addition to being a physician he was a bibliophile, historian, author, and renowned practical joker. He was passionate about medical libraries and medical history, having founded the History of Medicine Society (formally "section"), at the Royal Society of Medicine, London. He was also instrumental in founding the Medical Library Association of Great Britain and Ireland, and the (North American) Association of Medical Librarians (later the Medical Library Association) along with three other people, including Margaret Charlton, the medical librarian of his alma mater, McGill University. He left his own large history of medicine library to McGill, where it became the Osler Library.

Biography

Family William Osler's great-grandfather, Edward Osler, was variously described as either a merchant seaman or a pirate. One of William's uncles, Edward Osler (1798–1863), a medical officer in the Royal Navy, wrote the Life of Lord Exmouth and the poem The Voyage. William Osler's father, the Reverend Featherstone Lake Osler (1805–1895), the son of a shipowner at Falmouth, Cornwall, was a former lieutenant in the Royal Navy who served on HMS Victory. In 1831, Featherstone Osler was invited to serve on HMS Beagle as the science officer for Charles Darwin's historic voyage to the Galápagos Islands, but he turned it down because his father was dying. In 1833, Featherstone Osler announced that he wanted to become a minister of the Church of England. As a teenager, Featherstone Osler was aboard HMS Sappho when it was nearly destroyed by Atlantic storms and remained adrift for weeks. Serving in the Navy, he was shipwrecked off Barbados. In 1837, Featherstone Osler retired from the Navy and emigrated to Canada, becoming a "saddle-bag minister" in rural Upper Canada. When Featherstone and his bride, Ellen Free Picton, arrived in Canada, they were nearly shipwrecked again on Egg Island in the Gulf of Saint Lawrence. Their children included William, Britton Bath Osler and Sir Edmund Boyd Osler.

Early life William Osler was born in Bond Head, Canada West (Ontario), on July 12, 1849, and raised after 1857 in Dundas, Ontario. He was named William after William of Orange, who won the Battle of the Boyne on July 12, 1690. Osler's mother, who was very religious, prayed that he would become a priest. Osler was educated at Trinity College School (then located in Weston, Ontario). In 1867, Osler announced that he would follow his father's footsteps into the ministry and entered Trinity College of the University of Toronto, in the autumn. However, he became increasingly interested in medical science under the influence of James Bovell and the Rev. William Arthur Johnson, encouraging him to switch his career. In 1868, Osler enrolled in the Toronto School of Medicine, a privately owned institution that was not part of the Medical Faculty of the University of Toronto. Osler lived with James Bovell for a time, and through Johnson, he was introduced to the writings of Sir Thomas Browne; his Religio Medici caused a deep impression on him. Osler left the Toronto School of Medicine after being accepted into the MDCM program at the McGill University Faculty of Medicine in Montreal in 1870. Osler received his medical degree (MDCM) in 1872. While studying at McGill, Osler lived on lower Saint Urbain Street, at a time when the medical school was on nearby Côté Street. While in Montreal, Osler, who was a practicing Anglican regularly attended the "free seat" Chapel of St. John the Evangelist which at the time was located on Dorchester Street (now René Lévesque Boulevard). Osler held the chapel's rector, Fr. Edmund Wood in high regard due to his care for the less fortunate. Osler had personal copies of the 1662 Book of Common Prayer and Hymns Ancient and Modern, both of which are kept in the Osler Library of the History of Medicine at McGill. Osler and Fr. Wood would later on contribute to the installation of a memorial stained glass window in honour of Rev. Dr. William Wright, a professor of Materia medica at the McGill Faculty of Medicine and also a long time associate priest at the Church of St. John the Evangelist, which had since built a new church building on Ontario Street (now President Kennedy Avenue) and Saint Urbain, a few blocks north of the chapel's former location.

Career Following post-graduate training under Rudolf Virchow in Germany, Osler returned to the McGill University Faculty of Medicine as a professor in 1874. There he created the first formal journal club, showed interest in comparative pathology, and is considered the first to have taught veterinary pathology in North America as part of a broad understanding of disease pathogenesis. In 1884, he was appointed Chair of Clinical Medicine at the University of Pennsylvania in Philadelphia and in 1885, was one of the seven founding members of the Association of American Physicians, a society dedicated to "the advancement of scientific and practical medicine." When he left Philadelphia in 1889, his farewell address, "Aequanimitas", was about the imperturbability (calm amid storm) and equanimity (moderated emotion, tolerance) necessary for physicians.

Worked examples

Example 1 — a first encounter with William Osler

Start with the simplest possible case. Write down what William Osler claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to William Osler before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about William Osler ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of William Osler

In research
William Osler appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses William Osler in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
William Osler is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1849 births, 1919 deaths, Academics from Simcoe County, so understanding it makes those chapters shorter.
In everyday life
Look for William Osler outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
