Bhim Shanker Trivedi obtained MSc (Botany) (first class and first) and PhD from Lucknow University. He worked as Research Assistant with Professor Birbal Sahni till 1947. He joined as Lecturer, Botany Department, Lucknow University (1947), and became Reader, Professor and Head of the Department there. He also had worked in the University of Malaya, Singapore with Professor RE Holttum (1953-54).

Academic and Research Achievements: Trivedi had keen interest in the areas: cryptogams, hanerogams and fossil botany and made pioneering contributions in Tertiary megafossils. Geologists were of the opinion that saline series salt range in Punjab (now in Pakistan) was of Cambrian age. Studies made by Sahni and Trivedi showed that the saline Series were Tertiary in age rather than Cambrian. He collected samples of coal from Kuala Lumpur, Malaysia which was supposed to be unfossiliferous. He analyzed and found large number of spores and pollen grains and described the new genus and species, Malayaeaspora costata of schizaeaceous affinity. He described and worked out the Tertiary fossil flora of Mohgaon Kalan, Madhya Pradesh and Kalagarh, Bijnor district, Uttar Pradesh having a large number of dicotyledon, monocotyledon woods, petiole and other angiospermous remains. A new species of Azolla, viz. A. indica was reported from Mohgaon Kalan, which received wide attention. He reported about 20 new species of trilete megaspores from Singrauli Coalfield, and also described some Jurassic fossils from Shan State of Burma (now Myanmar). He studied the effect of strong magnets on the gametophytes of climbing fern, Lygodium flexuosum. TEM studies carried out by him revealed that due to strong magnetic field, their lamellae of chloroplasts got broken leading to their ultimate death. He also studied the effect of glucose on the sperms of Lygodium flexuosum and found that they show maximum motility and longevity in an optimum concentration of dilute solution of glucose. He made extensive studies on the stomata of angiosperms including Dicotyledons and Monocotyledons, and the spermoderm of a large number of Leguminous seeds. He has published large number of research papers in reputed journals, published four text books of botany and mentored 23 PhD students.

Other Contributions:Trivedi was one of the founder members of Birbal Sahni Institute of Palaeobotany, Lucknow and served on its Governing Council for 15 years.

Awards and Honours:Professor Trivedi was elected Fellow and also President of Palaeobotanical Society, and Indian Botanical Society of which he was Life Member also.
