The Story of Kamala Sohonie: The First Indian Woman to Earn a PhD in Biochemistry
Kamala Sohonie’s career began with a question that was both scientific and social: why should a woman with the required education be denied the opportunity to conduct research? Her answer was not delivered through slogans alone. She entered laboratories, produced original work, and helped connect biochemistry with public health.
Born Kamala Bhagvat in 1911, she grew up in a family with strong scientific interests. Her father and uncle had studied chemistry at the Indian Institute of Science (IISc) in Bengaluru. She completed her undergraduate studies in chemistry and physics at Bombay University, graduating at a time when very few Indian women were encouraged to pursue scientific careers.
Her achievements matter today because they show how evidence, persistence, and institutional accountability can challenge accepted assumptions. They also offer a valuable example of Indian science developing through both fundamental research and practical work on nutrition.
A determined student in colonial India
After completing her degree in 1933, Sohonie applied to the Indian Institute of Science for postgraduate research. The institute’s director, Nobel laureate C. V. Raman, initially rejected her application because she was a woman. This decision reflected the gender prejudice of the period rather than any assessment of her academic ability.
Sohonie refused to accept the decision quietly. She reportedly protested outside Raman’s office and secured admission under strict conditions. She had to prove herself through demanding laboratory work, but her performance made it increasingly difficult to justify excluding women from advanced scientific training.
Her admission was a landmark because it opened a prestigious research institution to women. It also revealed an important principle: institutions that claim to value merit must examine whether their rules and customs actually permit merit to be recognised.
Breaking the laboratory barrier
At IISc, Sohonie studied the chemistry of proteins and enzymes. The work required patience, accuracy, and long hours at a time when laboratory facilities in India were limited. Her presence challenged the assumption that women were unsuited to experimental science or unable to manage rigorous research.
The significance of her achievement can be seen by comparing the obstacles she faced with the wider scientific impact of her work:
| Challenge | Sohonie’s response | Wider significance |
|---|---|---|
| Gender-based exclusion from research | Persisted until she was admitted to IISc | Helped establish women’s place in Indian laboratories |
| Limited access to advanced training | Sought doctoral study abroad | Connected Indian research with international biochemistry |
| Academic work separated from social needs | Investigated nutrition and affordable foods | Demonstrated the public value of biochemistry |
| Prevailing assumptions about ability | Produced original experimental results | Replaced prejudice with evidence |
Her early career therefore involved two kinds of research. In the laboratory, she investigated biological processes. In society, her career tested the claim that scientific ability depended on gender.
Cambridge and the study of cellular life
In the mid-1930s, Sohonie travelled to the University of Cambridge for doctoral research. Cambridge exposed her to advanced biochemical methods and to a research environment in which the chemistry of living systems was being studied with increasing precision.
Her work focused on cytochrome C, a protein involved in cellular respiration. Cellular respiration is the process by which cells use nutrients to release energy, and cytochrome C plays a central role in the electron transport chain. Studying such molecules helped scientists understand how life functions at the cellular level.
Sohonie completed her doctorate in a remarkably short period, often reported as about fourteen months. Her research contributed to the growing field of enzymology and established her as a serious biochemist. She became the first Indian woman to earn a PhD in biochemistry, turning a personal breakthrough into an institutional milestone.
Returning research to India
After Cambridge, Sohonie returned to India rather than building her career permanently overseas. She worked at institutions including the Royal Institute of Science in Bombay, where she continued research in biochemistry and nutrition. Her scientific interests increasingly moved towards questions that affected ordinary people.
One important area was Neera, the fresh sap collected from palm trees. Sohonie and her collaborators examined its nutritional value, including its content of vitamin C and other nutrients. The work explored whether an inexpensive, locally available food could support the health of vulnerable communities.
This approach reflected a practical understanding of science. Fundamental knowledge about proteins, vitamins, and metabolism could become useful when connected to food security and public health. Research did not have to remain confined to academic journals; it could inform responses to malnutrition.
Nutrition, public health, and social responsibility
Sohonie’s studies of Neera included its possible value for children and pregnant women, particularly among undernourished tribal communities. The research examined how a traditional resource might contribute to better nutrition when processed and used appropriately.
Her work also demonstrated why scientific claims must be tested rather than accepted because they sound culturally familiar or authoritative. Traditional foods can contain valuable nutrients, but their benefits, safety, dosage, and limitations require careful investigation. Scientific temper respects useful evidence without romanticising or dismissing tradition.
The same critical habit is necessary when scientific vocabulary is used to defend social inequality. Sohonie’s career helps illustrate why caste claims and science should be examined through evidence, history, and logic rather than inherited authority.
What her career teaches today
Kamala Sohonie’s life offers several lessons for students, educators, and institutions:
- Talent can be overlooked when social prejudice is mistaken for objective judgement.
- Scientific institutions must make access fair in practice, not merely equal in official statements.
- Basic research and public-interest science strengthen each other.
- Local resources deserve investigation, but claims about them must be tested rigorously.
- A scientist’s social responsibility includes communicating evidence clearly to the public.
Her achievement was not simply that she became the first Indian woman with a doctorate in biochemistry. She also helped broaden the meaning of scientific success in India. A research career could involve cellular biology, nutrition, public health, and the creation of opportunities for those who came after.
Remembering Kamala Sohonie means more than celebrating a historic first. It means asking whether present-day laboratories are genuinely open to every capable student, whether research addresses real needs, and whether public debate gives evidence greater weight than status or tradition.
