Book excerpt: In his time the most famous physician in the world, Canadian-born William Osler (1849-1919) is still the best-known figure in the history of medicine. This new, definitive biography by Michael Bliss is the first full-scale life of Osler to appear since 1925. An award-winning medical historian, Bliss draws on many untapped sources to recreate Osler's life and medical times for a new generation of readers. Born at Bond Head, north of Toronto, Osler rose from obscurity to become the greatest medical teacher and writer in three countries. At Canada's McGill University, America's Johns Hopkins University, and finally as regius professor at Oxford, Osler was idolized by two generations of medical students and practitioners, for whom he came to personify the ideal doctor. His quest was to bring high standards and scientific methods into general practice in the medical world and to give teaching hospitals a solid place in the education of doctors. The publication of his book, The Principles and Practice of Medicine (1892), established him as the authority of modern medicine, a position he held well into the new century. Osler was revered as the high priest of the advent of twentieth-century medicine. In this fine biography, Michael Bliss animates the epic quality of Osler's life - not only in telling his personal story, but in setting that story against the dramatic backdrop of the coming of modern medicine.
