Ronald Ross was the first one to throw a new light on the mechanism of malarial transmission in the humans. The crux of the issue surrounding his work was he used the birds for his scientific experiments. His work, however, was not based on malarial transmission in the humans. Since his concept and work formed a trail blazer, not tried before, he received the Nobel award in 1902.
It all began with his accidental trip to a place near Ooty, a famous hill station in Tamil Nadu where he observed two varieties of odd-looking Anopheles mosquitoes that were believed to be the carriers of the germ and he could confirm his observation only later. He dissected the mosquitoes after they had bitten his volunteers, and on 20 August 1896, a clinical experiment with a patient showed the dapple-winged Anopheles mosquito was the culprit and a carrier of the parasite plasmodium. This unexpected discovery was of immense value to the tropical and subtropical countries where people died in thousands caused by malarial fever in the 18th and 19th centuries.
The Ross memorial is located on the Northern wall of the Presidency General (PG) Hospital, Kolkata where Dr. Ross resumed his pioneering work in the later part of 1800s by using the birds for his research on the parasites. A plaque on the boundary wall of SSKM Hospital, Calcutta, says: “In the small laboratory 70 yards to the south east of this gate Surgeon Major Ronald Ross I.M.S. in 1898 discovered the manner in which malaria is conveyed by mosquitoes.”

Ross' Secunderabad connection:
On 20 August 1897 Ronald Ross here in Secunderabad surprisingly discovered how malarial parasites were transmitted among the humans by the Anopheles mosquitoes.
The malaria archives of the United States Centers for Disease Control and Prevention has the most authentic document that says:
“On 20 August, 1897, in Secunderabad, [Ronald] Ross made his landmark discovery. While dissecting the stomach tissue of an anopheline mosquito fed four days previously on a malarial patient, he found the malaria parasite and went to prove the role of the Anopheles mosquitoes in the transmission of malaria parasites in humans…. He continued his research into malaria in India, using a more convenient experimental model, malaria in birds.”
