To Sir, With Love

In this biography, the life of William Hugh Isbister is traced through three continents, where he planted the seeds of academic surgery into a generation of leaders in colorectal surgery. This ultimately improved the care for thousands of patients. His last station in Saudi Arabia made a huge impact on the country. I hope this article inspires others to write about their mentors who were important in their development as surgeons and physicians. Short biographies of these important figures will serve as a valuable historical record for generations to come.
