Vishwa Nath obtained PhD (1925), and ScD (1957) from University of Cambridge, UK. He served as Professor of Zoology, Mahindra College, Patiala, Professor of Zoology, Government College, Lahore (1942-47), Principal, Government College, Dharamsala (1947), Principal, Government College, Hoshiarpur (1948-52), Professor of Zoology, Panjab University (1952-59) and University of Jodhpur (1963-65).

Academic and Research Achievements: Viswa Nath worked on the reproductive organs of scorpions and mosquitoes under James Gray of Cambridge. He studied in great detail cell biology and his work on spermatid and the sperm of the crab (Paratelphusa spinigera) and prawn (Palaemon lamarrei) is well known. He demonstrated, for example, that the spermatozoon explodes at the time of fertilization and that its weird form gets transformed into that of a typical one. He also suggested that, just as in the case the crab, the cytoplasmic vesicle of the prawn sperm also provides the mechanism for its explosion during fertilization. He authored the books: Zoology for Intermediate Students, The Decapod Sperm, A Text book of Zoology, Animal Gametes (Male), Animal Gametes (Female) and Cell Biology.

Awards and Honours: Professor was conferred the Viswa Nath Joy Govinda Law Memorial Gold Medal by the Asiatic Society (1968), and was President, Zoology Section, Indian Science Congress (1944). He was elected Fellow of the Royal Microscopical Society, London.

The Indian National Science Academy has instituted `Viswa Nath Memorial Lecture’ in his honour.
