Asok Ghosh obtained his PhD degree (1955) from the University of Calcutta. He specialized in comparative endocrinology and histochemistry. He worked on correlation of avian phylogeny with epinephrine-norepinephrine ratio. He discovered differential pattern of synthesis, storage and release of adrenomedullary catechol hormones depends upon neruohormonal modulation. His contribution brought to light the etiology of resistance of avian diabetogenesis. He was a Visiting Endocrinologist, University of California, Berkeley, USA. He was Assistant Professor, Veterinary College, Kolkata. He was the National member of International Union of Biological Sciences, International committee for Avian endocrinology. He was the recipient of JC Bose Award (1979), Joy Gobind Law Medal (1984). He was Founder Fellow of Asia and Oceannia Society for Comparative endocrinology.

Mahdi Hasan obtained his MBBS and MS (with Honours in Anatomy)(1963) from Lucknow University. He went on German Exchange Fellowship (DAAD) to Goettingen to learn electron microscopy and neuroanatomy(1965). He further investigated age associated changes in the brain, mapping regional distribution and heterogeneity of neuronal lipofuscin (age pigment). He was the Director, Interdisciplinary Brain Research Centre. He set up a Central Electron Microscope facility at Aligarh. He was the President, Indian Academy of Neurosciences, Anatomical Society of India, and Association of Gerontology. He was on the International Advisory Board of Neurotoxicology (USA). He was the recipient of BC Roy National Award(1991), Ativishisht Chikitsa Medal of College of Chest Physicians of India (1995), and Dr Bachhawat Life-Time achievement award of Indian Academy of Neurosciences(2004).
