Sachi Prasad Ray-Chaudhuri: <i>Drosophila</i> genetics and mutagenesis in Indian science

This article summarizes the scientific contributions of Professor Sachi Prasad Ray-Chaudhuri and his unwavering commitment to advancing research and teaching in mutagenesis and genetics in post-independence India, following his postgraduate training in the United Kingdom under the mentorship of Professor H. J. Muller. His contributions in basic mutagenesis, radiation protection, animal cytogenetics and population genetics using a range of model and native species laid the foundation of scientific research in India in these contemporary field. This played a pivotal role in advancing genetics and biological sciences in India at a time when scientific infrastructure and resources were limited. He also took the initiative to modernize the curriculum of biology teaching in India in line with the developments in the subject globally. He expanded these efforts by teaching as a visiting professor in different, often remote parts of the country where he inspired the students. The seeds of his relentless effort to connect the advances in Indian science with those in the rest of the world have blossomed, and Indian science today contributes significantly to the global knowledge base. His pioneering scientific contributions and inspiring legacy continue unabated.
