He was a great scientific investigator. As such his work was 

 thorough, he touched no subject on which his investigations did not 

 throw light and in most cases he left the subject standing clearly, the 

 obscurities gone. He was a leader, not a follower, his researches were 

 carefully planned, he used all methods of approach, and was fertile in 

 devising new methods of work. His individual contributions, of which 

 there are more than a hundred, and the five hundred contributions 

 from his laboratory, rank with highest contributions to the science of 

 anatomy. 



He was active in the promotion of opportunities for the advance of 

 medical science in all places, his advice was always sought and valued, 

 and his influence has been very great in the advance of medical teach- 

 ing in this country and elsewhere. He led a simple and quiet life, was 

 a good citizen, a good friend.

 son of Reverend F. L. Osier. Beginning his medical training at the 

 University of Toronto, he continued it at McGill whence he received 

 his M.D. degree in 1872. Two years were spent in study abroad at 

 London, Berlin and Vienna. Returning to Montreal in 1874 he was 

 made Lecturer on the Institutes of Medicine at McGill, and shortly 

 afterwards was given the Professorship. This began what continued 

 to be, for him, the chief interest of his life, for Osier, more than anything 

 else, was a teacher, first at McGill, later at the University of Pennsyl- 

 vania, then at Johns Hopkins, where he exerted his greatest influence 

 as an inspiring leader of an increasingly large group of students, and 

 finally at Oxford, where, as Regius Professor of Medicine, he held a 

 unique position of influence on both American and British medicine. 



In the early days of his medical career Osier was a diligent student of 

 pathology and contributed important studies in this field, notably on
