(1857 1932) Sir Ronald Ross was born in India in 1857 at Almora, a town near Kumaon hills. He was sent to England for his schooling and medical education. In 1881 he returned to India and joined the British Army as Medical Officer. In 1889 he went to England on leave where he met Dr. Patrick Manson who advised him to work for the discovery of the mode of spread of malarial fever. After his return from England he was posted to Madras, Bangalore and then to Hyderabad.

At Begumpet he worked in a red-tiled building which still exists (adjacent to the airport). He worked in difficult circumstanceswith very limited resources. On 20th August, 1897 he discovered that a particular type of mosquito called Anopheles was responsible for malaria. In 1902 Ronald Ross was awarded the Nobel Prize for his important work in the field of tropical medicine. A marble stone was erected in the Begumpet building by the Cantonment authority in 1935 in memory of this great man. Ross died in 1932 in England.
