Indian Scientist

             Sir Ronald Ross


Ronald Ross was born in India in 1857 in Almora district located in present day Uttrakhand. His father was a General in the British army in India. Ross lived in India until was 8. Then he was sent to a boarding school in England. Studied medicine from St. Bartholomew Hospital in London. When Rose was small boy ,saw many people in India fall ill with malaria. At least a million people would die of Malaria due to lack of proper meditation .When Rose fathers fell seriously ill with Malaria, but fortunately recovered this deadly disease left an impression on age mind. When rows returned to India is part of the British Indian Medical Services, he was sent to Madras where a last part of his work was treating Malaria patient in the army. Ronald Ross in 1897 the long suspected link between mosquito and malaria. Confirmed the hypothesis.



 Till date time, it was believed that Malaria is caused by breathing in bed and living in hot humid and Masi environment. Ross studied in malaria between 1882 and 1899. While posted in Ooty,he  fell ill with Malaria. After this he was transferred to the medical school in Osmania University, Secunderabad .He discovered the presence of the malaria parasite within a specific species of mosquito of the genus Anopheles. He initially called them Dapple Wings. Ross made his crucial Discovery while dissecting the stomach of a mosquito feed on the blood of a Malaria victim . He found the previously observed parasite. Through further study, he established the complete life cycle of the parasite. He contributed majorly to the epidemiology of malaria and brought a method to its survey and assessment. He made mathematical model for further study. In 1902 ,Ross was awarded the Nobel Prize in medicine for his remarkable work on malaria and was conferred knighthood as mark of his great contribution of the world of medicine. In 1926, he became the director of the Ross Institute and hospital for tropical disease in London, which was found in his honour.


In India, Ross is remembered with great respect and love. There are roads named after him in Indian towns and cities. The regional infectious disease hospital at Hyderabad was named after him as  sir Ronald Ross Institute of tropical and communicable disease , in recognition of his  services. The building where he worked and actually discovered the malaria parasite ,located in Secunderabad near the old Begumpet Airport, is aHeritage site and the road leading up to the building is named sir Ronald Ross Road.

 A small Memorial on the walls of sskm hospital Kolkata commemorates Ross'discovery . The memorial was unveiled by Ross himself, in the presence of Lord Lytton on 7 January 1927.

While many believe that he was born in Pataliputra in Magadha, present-day Patna in the state of Bihar, others are of the view that he was born in Kerala and lived  Magadha at the time of the Gupta rulers. His works include the Aryabhamiya (499 CE, when he was 23) and the Arya Siddhanta.  His most famous work, Aryabhatiya is a detailed text on mathematics and astronomy. The mathematical part of the Aryabhatiya covers arithmetic, algebra and trigonometry. It also contains continued fractions, quadratic equations, sums of power series and a table of sines. Aryabhatta is believed to have written at least three texts on astronomy and wrote some free stanzas as well. Aryabhatta was a genius and all his

He passed his Bachelors in physics in 1879.  In 1880, Bose went to England. He studied medicine at London University for a year but gave it up because of his ill health. Within a year, he moved to Cambridge to take up a scholarship to study Natural Science at Christ's College, Cambridge. In 1885, he returned from abroad with a BSc degree and Natural Science Tripos (a special course of study at Cambridge). In 1894, Jagadish Chandra Bose decided to devote himself to pure research. He converted a small enclosure adjoining a bathroom in the P
