Bibha Chowdhuri is often overlooked in discussions about India’s scientific pioneers. As a trailblazer in cosmic ray research, she made foundational contributions to particle physics during a time when women were seldom seen in this field. A newly released biography seeks to restore her legacy within the annals of India’s scientific history.
Born in 1913 in Kolkata, Chowdhuri was raised in an environment that fostered intellectual growth. In 1936, she completed her MSc in physics from Calcutta University, standing out as the only woman in her class. Shortly thereafter, she joined the Bose Institute as a research assistant to Debendra Mohan Bose. Together, they published three influential papers in the journal “Nature,” focusing on photographic emulsion techniques for cosmic ray detection.
Chowdhuri's early experiments with Bose led to the detection of mesons years before C.F. Powell's Nobel Prize-winning work used a similar methodology. Unfortunately, wartime shortages of sensitive plates hindered their progress, which may have cost them global recognition. Nonetheless, Powell later acknowledged their groundbreaking contributions to the field of cosmic rays.
Chowdhuri earned her PhD at the University of Manchester in 1945 under the guidance of Nobel laureate P.M.S. Blackett. In 1949, she was appointed as the first woman researcher at the Tata Institute of Fundamental Research. Later, she contributed to major high-energy physics projects, including the Kolar Gold Mine experiments at the Physical Research Laboratory in Ahmedabad. Even after facing institutional challenges, she continued her research independently in Kolkata, collaborating with leading scientific institutes and publishing her findings actively until late in her life.
Despite her significant contributions, Chowdhuri did not receive major national awards or fellowships during her lifetime. Her absence from mainstream scientific narratives highlights systemic issues in recognizing women scientists. A recent biography by Rajinder Singh and Suprakash C. Roy has revived her story, ensuring that her invaluable contributions finally receive the acknowledgment they deserve.
