One of the oldest departments to be set up in King George Hospital was upgraded in 1923 to a full pledged department. Initially, the medical wards were housed in M1, M2, and M3 wards (present S2, urology, plastic surgery & cancer). The two blocks of Bhavanagar and Rajendra Prasad were inaugurated in 1949 and 1955 by the then governor of Madras and the then president of India respectively after whom they were named. The acute medical care unit is indeed a boon to the acutely ill patients. It runs for 24 hours. It has an attached clinical laboratory. Dr. W.C.Gray, IMS was the first professor and head. A number of medical luminaries followed in his footsteps.
