Douglas Argyll Robertson

Born in 1837, Douglas Argyll Robertson was a Scottish ophthalmologist and surgeon whose career became closely tied to the growth of modern eye medicine. He studied medicine at the University of St Andrews and then continued his training in Berlin under the influential ophthalmologist Albrecht von Graefe, bringing advanced ideas back to Britain.

He built his reputation in Edinburgh, where he worked as an eye surgeon and teacher. Robertson is most widely remembered for describing the pupil sign now known as the Argyll Robertson pupil, in which the pupils react when focusing on a near object but not to light. That observation became an important clinical clue in neurological disease and helped secure his place in medical history.

Beyond the famous eponym, he was part of a generation of physicians who helped make ophthalmology a more precise and specialized field. His name still appears in medical teaching today, a reminder of how one sharp bedside observation can last for more than a century.
