Douglas Argyll Robertson

Born in Edinburgh in 1837, Douglas Argyll Robertson grew up in a medical family and studied medicine at the University of St Andrews. He went on to deepen his training in Europe, especially in Berlin, before building his career in Edinburgh as an ophthalmologist and surgeon.

He is remembered above all for describing the pupil abnormality that came to bear his name, a finding that became an important clue in neurological and systemic disease. He also introduced physostigmine into ophthalmic practice, an important step in the treatment of eye conditions, and his wider work helped shape nineteenth-century eye surgery.

Robertson earned major professional recognition in his lifetime, including service as president of the Royal College of Surgeons of Edinburgh. He died on January 3, 1909, while traveling near Bombay, leaving a legacy that still appears in medical textbooks and clinical teaching.
