Bibha Chowdhuri stands as one of India’s most remarkable yet overlooked scientists. A pioneering physicist in the field of cosmic rays, she made foundational contributions to particle physics at a time when women in science were exceedingly rare. A new biography now brings her story to light, finally giving her the recognition history overlooked.
Early Life and Academic Journey
Born in 1913 in Kolkata, Chowdhuri grew up in an intellectually rich environment. She graduated with an MSc in Physics from Calcutta University in 1936—the only woman in her class.
Soon after, she joined the Bose Institute as a research assistant under physicist Debendra Mohan Bose. Together, they conducted groundbreaking research using photographic emulsion techniques to study cosmic rays. Their work led to three papers published in Nature—a rare accomplishment for an Indian scientist of the era.
Ahead of Her Time: The Uncredited Meson Discovery
Chowdhuri’s experiments detected evidence of mesons years before C.F. Powell’s Nobel Prize-winning research used similar methods. However, wartime shortages of high-quality photographic plates prevented their findings from being globally recognised. Powell later acknowledged that their contributions laid the foundation for the field.
Career Milestones: India’s First Woman Physicist in Top Institutions
After earning her PhD under Nobel laureate P.M.S. Blackett at the University of Manchester in 1945, Bibha returned to India.
Key milestones include:
- 1949: Appointed by Homi J. Bhabha as the first woman researcher at TIFR.
- Later contributed to the Kolar Gold Field experiments, India’s most ambitious high-energy physics project.
- Continued research independently in Kolkata after institutional setbacks.
She worked and published actively well into her later years.
Legacy: Recognition Long Overdue
Despite her achievements, Bibha Chowdhuri never received a national award, fellowship, or the acknowledgment she deserved. Her absence from mainstream scientific narratives exposes longstanding gender bias in Indian STEM history.
A new biography by Rajinder Singh and Suprakash C. Roy now seeks to restore her rightful place as a pioneer of Indian physics.
