Chitta Ranjan Dasgupta earned the DTM degree from the University of Calcutta, with a specialization in Haematology. He worked severally as the In-charge of Civil and Hospital Transfusion Service at the School of Tropical Medicine, Calcutta, and as Senior Visiting Physician, Carmichael Hospital for Tropical Diseases (1942-55), Deputy Director (1951-52, 1953-54), Visiting Haematologist and In-charge of Pathology Department, Islamia Hospital, Kolkata and Visiting Haematologist, Ramakrishna Mission Sishumangal Sevapratisthan (1956-59).

Academic and Research Achievements: Dasgupta showed sandfly Phlebotomus argentipes to be the vector of kala-azar. He not only showed that standfly transmitted the infection from man to man but also in newly born babies through intra-placental transmission. He also identified the clinical manifestations of post kala-azar dermal leishmaniasis and established the haematological norms of Indians and showed that the nutritional macrocytic anaemia, which resembled closely pernicious anaemia haematologically, was quite distinct from it. He showed that iron given orally would cure even severe anaemia due to heavy hookworm infestation while deworming alone would not cure it. He initiated studies in haemoglobinopathies and reported the beneficial effected of spleen extract in thrombocytosis. Dasgupta was the first to note that in West Bengal the incidence of blood groups B and O was higher than of group A and that 85 per cent of the population were Rh (D) positive. He also made extensive studies on the action of leucopoietic drugs.

Other Contributions: Chitta Ranjan Dasgupta was a member of Nutrition Advisory Committee, Government of West Bengal from 1940 to 1955 and that of the Maternity and Child Welfare Committee from 1949 to 1957. He was the Chairman of Haemotological Sub-Committee from 1950 to 1955, and served on the editorial boards of Indian Journal of Medical Research and Journal of Indian Medical Association. He was the Vice-President, from 1956 to 1959, of the International Society of Haematology and Indian Medical Association (West Bengal Branch) from 1953 to 1954. He was also elected President of Asian and Pacific Society of Haematology in 1960 and Indian Society of Haematology & Blood Transfusion from 1959 to 1960.
