Ross was apolymath, writing a number of poems, publishing several novels, and composing songs. He was also an amateur artist and mathematician. He worked in theIndian Medical Service for 25 years. It was during his service that he made the groundbreaking medical discovery. After resigning from his service in India, he joined the faculty ofLiverpool School of Tropical Medicine, and continued as Professor and Chairman ofTropical Medicine of the institute for 10 years. In 1926, he became Director-in-Chief of the Ross Institute and Hospital for Tropical Diseases, which was established in honour of his works. He remained there until his death.[3][4]
Ross was born inAlmora, then in theNorth-Western Provinces ofCompany-ruled India, north west of Nepal.[1] He was the eldest of ten children of SirCampbell Claye Grant Ross, a general in theBritish Indian Army, and Matilda Charlotte Elderton. At age eight, he was sent to England to live with his aunt and uncle on theIsle of Wight. He attended Primary schools atRyde, and for secondary education he was sent to a boarding school at Springhill, nearSouthampton, in 1869. From his early childhood, he developed a passion for poetry, music, literature andmathematics. At fourteen years of age he won a prize for mathematics, a book titledOrbs of Heaven which sparked his interest in mathematics. In 1873, at sixteen, he secured first position in theOxford and Cambridge local examination in drawing.[5]
Ross embarked for India on 22 September 1881 on the troopshipJumma. Between 1881 and 1894 he was variously posted inMadras,Moulmein (in Burma/Myanmar),Baluchistan,Andaman Islands,Bangalore andSecunderabad. In 1883, he was posted as the Acting Garrison Surgeon at Bangalore during which he noticed the possibility of controlling mosquitoes by limiting their access to water. In March 1894 he had his home leave and went to London with his family. On 10 April 1894 he met SirPatrick Manson for the first time. Manson who became Ross's mentor, introduced him to the real problems in malaria research. Manson always had a firm belief that India was the best place for the study. Ross returned to India onP&O shipBallaarat on 20 March 1895 and landed in Secunderabad on 24 April.[8] Even before his luggage was cleared in the custom office, he went straight for Bombay Civil Hospital, looking for malarial patients and started making blood films.
The page in Ross' notebook where he recorded the "pigmented bodies" in mosquitoes that he later identified as malaria parasites
Ross made his first important step in May 1895 when he observed the early stages of malarial parasite inside a mosquito stomach. However, his enthusiasm was interrupted as he was deployed to Bangalore to investigate an outbreak ofcholera. Bangalore had no regular cases of malaria. He confided to Manson stating, "I am thrown out of employment and have 'no work to do'." But in April he had a chance to visit Sigur Ghat near the hill station ofOoty, where he noticed a mosquito on the wall in a peculiar posture, and for this he called it "dappled-winged" mosquito, not knowing the species. In May 1896, he was given a short leave that enabled him to visit a malaria-endemic region around Ooty. In spite of his daily quinine prophylaxis, he was down with severe malaria three days after his arrival. In June he was transferred toSecunderabad.[2][9]
After two years of research failure, in July 1897, Ross managed to culture 20 adult "brown" mosquitoes from collected larvae. He successfully infected the mosquitoes from a patient named Husein Khan for a price of 8annas (one anna per blood-fed mosquito). After blood-feeding, he dissected the mosquitoes. On 20 August he confirmed the presence of the malarial parasite inside the gut of mosquito, which he originally identified as "dappled-wings" (which turned out to be a species of the genusAnopheles). The next day, on 21 August, he confirmed the growth of the parasite in the mosquito. This discovery was published on 27 August 1897[10] in the Indian Medical Gazette and subsequently in the December 1897 issue ofBritish Medical Journal.[11][12] In the evening he composed the following poem for his discovery (originally unfinished, sent to his wife on 22 August, and completed a few days later):[13][14]
This day relenting God Hath placed within my hand A wondrous thing; and God Be praised. At His command, Seeking His secret deeds With tears and toiling breath, I find thy cunning seeds, O million-murdering Death. I know this little thing A myriad men will save. O Death, where is thy sting? Thy victory, O Grave?
Ross, Mrs Ross, Mahomed Bux, and two other assistants atCunningham's laboratory of Presidency Hospital in Calcutta
In September 1897, Ross was transferred to Bombay, from where he was subsequently sent to malaria-freeKherwara inRajputana (nowRajasthan). Frustrated by lack of work, he threatened to resign from the service as he felt that it was a death blow to his research. It was only on the representation of Patrick Manson that the government arranged for his continued service in Calcutta on "special duty".[3] On 17 February 1898, he arrived in Calcutta (nowKolkata), to work in thePresidency General Hospital (nowIPGMER and SSKM Hospital).[9]
Ross immediately carried out research in malaria andVisceral leishmaniasis (also known as kala azar), for which he was assigned. He was given the use of Surgeon-Lieutenant-General Cunningham's laboratory for his research. He had no success with malarial patients because they were always immediately given medication. He built a bungalow with a laboratory at Mahanad village, where he would stay from time to time to collect mosquitoes in and around the village. He employed Mahomed (or Muhammed) Bux and Purboona (who deserted him after the first payday). As Calcutta was not a malarious place, Manson persuaded him to use birds, as being used by other scientists such asVasily Danilewsky in Russia andWilliam George MacCallum in America. Ross complied but with a complaint that he "did not need to be in India to study bird malaria". By March he began to see results on bird parasites, very closely related to thehuman malarial parasites.[15]
Using more convenient model of birds (infected sparrows), by July 1898 Ross established the importance of culex mosquitoes as intermediate hosts inavian malaria. On 4 July he discovered that thesalivary gland was the storage sites of malarial parasites in the mosquito. By 8 July he was convinced that the parasites are released from the salivary gland during biting. He later demonstrated the transmission of malarial parasite from mosquitoes (in this caseCulex species) to healthy sparrows from an infected one, thus, establishing the complete life cycle of malarial parasite.[16][17][18][19][20][21]
In September 1898 he went to southernAssam in (northeast India) to study an epidemic of Visceral leishmaniasis. He was invited to work there by Graham Col Ville Ramsay, the second Medical Officer of the Labac Tea Estate Hospital. (His microscope and medicals tools are still preserved, and his sketches of mosquitoes are still on display at the hospital.)[22][23] However, he utterly failed as he believed that the kala-azar parasite (Leishmania donovani, the very scientific name he later gave in 1903) was transmitted by a mosquito, which he refers to asAnopheles rossi (scientific name given by G.M. Giles).[24] (It is now known thatkala azar is transmitted bysandflies.)
In 1899, Ross resigned from the Indian Medical Service and went to England to join the faculty of theLiverpool School of Tropical Medicine as a lecturer. He continued to work on prevention of malaria in different parts of the world, includingWest Africa, theSuez Canal zone,[25]Greece,Mauritius,Cyprus, and in the areas affected by theFirst World War. He also established organisations for fighting malaria in India and Sri Lanka. In 1902, Ross was awarded theCameron Prize for Therapeutics of the University of Edinburgh. He was appointed as Professor and Chair of Tropical Medicine of the Liverpool School of Tropical Medicine in 1902, which he held up to 1912. In 1912 he was appointed Physician for Tropical Diseases atKing's College Hospital in London, and simultaneously hold the Chair of Tropical Sanitation in Liverpool. He remained in these posts until 1917 when he became (honorary) Consultant inMalariology inBritish War Office. He travelled toThessaloniki and Italy in November to advise and on the way, "in a landlocked bay close to the Leucadian Rock (where Sappho is supposed to have drowned herself)", his ship escaped a torpedo attack.[26] Between 1918 and 1926 he worked as Consultant in Malaria in theMinistry of Pensions and National Insurance.
Ross developed mathematical models for the study of malariaepidemiology, which he initiated in his report on Mauritius in 1908. He elaborated the concept in his bookThe Prevention of Malaria in 1910[27] (2nd edition in 1911) and further elaborated in a more generalised form in scientific papers published by theRoyal Society in 1915 and 1916; some of his epidemiology work was developed with mathematicianHilda Hudson. These papers represented a profound mathematical interest which was not confined to epidemiology, but led him to make material contributions to both pure and applied mathematics.
The Ross Institute and Hospital for Tropical Diseases was founded in 1926 and established at Bath House, a grand house with keeper's lodge and large grounds adjacent to Tibbet's Corner atPutney Heath. The hospital was opened by the thenPrince of Wales, the future King Edward VIII.[30] Ross assumed the post of Director-in-Chief until his death.[6] The institute was later incorporated into theLondon School of Hygiene & Tropical Medicine in Keppel Street. Bath House was later demolished and mansion flats built on the property. In memory of its history and owner the block was named Ross Court. Within the grounds an older dwelling, Ross Cottage, remains.
When the 1902 Nobel Prize for Physiology or Medicine was considered, theNobel Committee initially intended the prize to be shared between Ross and Grassi, however Ross accused Grassi of deliberate fraud. The weight of favour ultimately fell on Ross, largely due to the influences ofRobert Koch, the appointed neutral arbitrator in the committee; as reported, "Koch threw the full weight of his considerable authority in insisting that Grassi did not deserve the honor".[33]
Ronald Ross was noted to be eccentric and egocentric, described as an "impulsive man"[34] or an "impulsive genius."[35] His professional life appeared to be in constant feud with his students, colleagues, and fellow scientists.[36] His personal vendetta with G. B. Grassi became a legendary tale in science. He was openly envious of his mentor Patrick Manson's affluence from private practices. HisMemories of Sir Patrick Manson (1930) was a direct attempt to belittle Manson's influences on his works on malaria.[8] He hardly had good ties with the administration of Liverpool School of Tropical Medicine, complaining of being underpaid. He resigned twice, and was eventually discharged without any pension.[37]
Ross was frequently embittered by lack of government support (what he called "administrative barbarism")[4] for scientists in medical research. In 1928 he advertised his papers for sale in the journalScience Progress in the Twentieth Century (1919–1933), with a statement that the money was for financial support of his wife and family. Lady Houston bought them for £2000, and offered them to theBritish Museum, which turned her down for various reasons. The papers are now preserved by theLondon School of Hygiene and Tropical Medicine[3][38] and theRoyal College of Physicians and Surgeons of Glasgow.[39]
In 1889 Ross married Rosa Bessie Bloxam (d.1931). They had two daughters, Dorothy (1891–1947) and Sylvia (1893–1925), and two sons, Ronald Campbell (1895–1914) and Charles Claye (1901–1966). His wife died in 1931. Ronald and Sylvia pre-deceased him too: Ronald was killed at theBattle of Le Cateau on 26 August 1914.[40] Ross died at the hospital of his namesake after a long illness andasthma attack. He was buried at the nearbyPutney Vale Cemetery, next to his wife.[41][42][43]
A small memorial on the walls ofSSKM Hospital, Calcutta commemorates Ross's discovery. The memorial was unveiled by Ross himself, in the presence of Lord Lytton, on 7 January 1927.[44] The laboratory where Ross worked has been transferred into a malaria clinic named after him. There is also a plaque on the outer wall.[45]
Sir Ronald Ross Institute of Parasitology is the building inBegumpet where Ross made the discovery that malaria was transmitted by the femaleanopheles mosquito on 20 August. 20 August later came to known as theWorld Mosquito Day. The lab has been transformed into a small museum exhibiting photos of Ross and his family. Various charts and diagrams explain Ross' work on malaria and its transmission.[45]

Ross was a prolific writer. He habitually wrote poems on most of the important events in his life. His poetic works gained him wide acclaim and they reflect his medical service,travelogue, philosophical and scientific thoughts. Many of his poems are collected in hisSelected Poems (1928) andIn Exile (1931). Some of his notable books areThe Child of Ocean (1899 and 1932),The Revels of Orsera,The Spirit of Storm,Fables and Satires (1930),Lyra Modulatu (1931), and five mathematical works (1929–1931). He also compiled an extensive accountThe Prevention of Malaria in 1910 and anotherStudies on Malaria in 1928. He published his autobiographyMemoirs, with a Full Account of the Great Malaria Problem and its Solution (547 pages long) in 1923. He carefully saved virtually everything about himself: correspondence, telegrams, newspaper cuttings, drafts of published and unpublished material, and all manner of ephemera.[4]
Plaque at Liverpool University – on the Johnston Building, formerly the Johnston Laboratories, near Ashton Street,LiverpoolRoss's name remembered on the London School of Hygiene and Tropical Medicine
Ronald Ross was awarded the Nobel Prize for Physiology or Medicine in 1902 "for his work on malaria, by which he has shown how it enters the organism and thereby has laid the foundation for successful research on this disease and methods of combating it".[48]
Ross received honorary membership of learned societies of most countries in Europe, and elsewhere. He got an honorary M.D. degree inStockholm in 1910 at the centenary celebration of theCaroline Institute and his 1923 autobiographyMemoirswas awarded that year'sJames Tait Black Memorial Prize. While his vivacity and single-minded search for truth caused friction with some people, he enjoyed a vast circle of friends in Europe, Asia and the United States who respected him for his personality as well as for his genius.[3]
In India, Ross is remembered with great respect as a result of his work on malaria, the deadly epidemic which used to claim thousands of lives every year. There are roads named after him in many Indian towns and cities. InCalcutta the road linkingPresidency General Hospital withKidderpore Road has been renamed after him as Sir Ronald Ross Sarani. Earlier this road was known as Hospital Road. In his memory, the regional infectious disease hospital atHyderabad was namedSir Ronald Ross Institute of Tropical and Communicable Diseases. The building where he worked and actually discovered the malarial parasite, located in Secunderabad near theBegumpet Airport, is a declared a heritage site and the road leading up to the building is named Sir Ronald Ross Road.
InLudhiana,Christian Medical College has named its hostel as "Ross Hostel". The young medics often refer to themselves as "Rossians".
In 2010 theUniversity of Liverpool named its new biological science building "The Ronald Ross Building" in his honour. His grandson David Ross inaugurated it. The building is home to the university's facility for the Institute of Infection and Global Health.[54]
