Prof. S.N. Dasgupta was born at Jalpaiguri on the 4th November, 1902. He completed his early education at Jalpaiguri Zilla School, Bangabasi College and Presidency College (Calcutta). He passed M.Sc. (Botany) with first class first from the University College of Sciences, Calcutta and received the University Gold Medal in 1925. For Ph.D. and D.Sc. degrees, he worked at the Imperial College of Science and Technology, London University. Prof. Dasgupta returned to India in 1934 and joined the Lucknow University as Reader in Botany. He was elevated as Professor and Head of the Department of Botany in 1949 and Dean, Faculty of Science in 1954. In 1960 he joined the Kalyani University as its first Vice- Chancellor from where he retired in 1968. Professor Dasgupta also served in the UNESCO and Public Service Commission, West Bengal for short periods.
At Lucknow University, Dr. Dasgupta established one of the finest schools of Mycology and Plant Pathology, which attracted students not only from various parts of India but from other countries as well. His early work on ‘Saltation of Fungi’ (published as a booklet in 1936) earned him great repute and his work was cited in international books and journals. Among the national problems he concentrated on diseases of complex etiology specially tip necrosis of mango. His team of workers demonstrated not only the cause but also developed economic means to control the disease (spraying borax). His work on aquatic fungi won the appreciation of world authority like Prof. Sparrow. He is one of the few mycologists who have contributed to Medical Mycology and his review in the Mycopathologia et Mycologia Applicata (in 1960) still serves as the most important document for planning research projects. He also laid a firm foundation to the establishment of researches on host-pathogen interactions, leather mycology, paper pulp mycology, predacious fungi, etc. At a time (1958-60) when scientists were groping in the dark and trying to relate virulence of a pathogen with a particular enzyme/toxin, he declared that it was the sum total of metabolic pattern that should be basically considered for the determination of aggressiveness of a pathogen. His dynamism and flare for critical research is well exhibited in the diverse aspects on which he published and guided research. The generation of scientists trained under him occupy responsible positions in Universities and Research Institutions not only in India but other countries as well. For his rich contributions and analytical approach, he was requested by the Indian Botanical Society to write the History of Plant Pathology in India, Burma and Ceylon which was published in the form of a book in 1958 and which still serves as an important reference for any plant pathologist. He delivered the 1st Jeerasannidhi Award Lecture of the Indian Phytopathological Society in 1982.
Professor Dr. Sachindra Nath Dasgupta expired on 11th September, 1990.
