Osler Centenary Papers: Osler, inscribed

Background As the centenary of Sir William Osler's death approaches on 29 December 2019, it is worth pausing to reflect on the relationship between the Osler Library of the History of Medicine at McGill University and the image of William Osler, for the two are arguably inextricable. When Osler died he had not yet completed his library, yet his donation to McGill included nearly 8000 volumes that represented the foundations of western medicine. The Osler Library now boasts over 100 000 titles and is recognised globally as a centre for the study of medical history. Methods The approach taken here was to examine inscriptions in the books that William Osler bequeathed to the McGill Medical Facultyin order to learn more about William Osler, the man. Results By examining inscriptions William Osler and others made in his books, it was possible to learn more about how Osler interacted with his friends, his patients, and also his books. Conclusion It is argued that these inscriptions are as instructive as they are enriching. They reveal information about Osler's priorities and his personal and professional relationships; future scholars will likely find it useful to examine inscriptions more broadly, to gain insight into such topics as the book trade and world events.
