The Department of Medicine came into being with the inception of Armed Forces Medical College on 01 May 1948. The First professor was the illustrious Lt Col S Medhi Basu who laid the foundation of this prestigious department. It was in 1967, under Brig RS Hoon, that the department moved to its present location.
