Kamala Sohonie’s science career moved from food proteins to plant respiration, then back to public nutrition.
Her path also challenged a gender barrier at the Indian Institute of Science. Her later research asked how familiar foods could support better nutrition.
The key distinction: Sohonie is commonly described as the first Indian woman to earn a PhD in a scientific discipline. Keep that degree wording precise.

Must know: from Bombay to Cambridge
From Bombay to Cambridge
Kamala Bhagvat graduated from Bombay University in 1933 with first-class standing. She then sought a research place in biochemistry at IISc. Her journey took her from Indian food research to doctoral work in Cambridge. The Institute of Science, Mumbai biography and the National Book Trust account describe this academic path.
Sources differ on her birthplace, Indore or Baroda. This lesson leaves birth details out.
The Institute of Science biography records her death in New Delhi on 28 June 1998.
How did she enter research at IISc?
Why was her admission a turning point?
IISc’s history account says director C. V. Raman first refused Sohonie entry because she was a woman. She persisted and gained admission. This made her access to research a challenge as well as an academic milestone. IISc Connect recounts the admission story.
Some biographies add specific probation conditions. The sources reviewed do not establish every condition as an IISc archival fact. This lesson keeps the verified point: she faced gender-based refusal, persisted, and joined the Institute.
Why does this admission story matter?
It shows that access to research was shaped by gender barriers. IISc’s account supports Sohonie’s persistence and eventual admission.

Good to know: where she studied
What did she study, and where?
Where was her MSc awarded?
At IISc, Sohonie researched food proteins, including proteins in pulses. She submitted her research to Bombay University, which awarded her MSc in 1936. This distinction matters: her research took place at IISc, while Bombay University awarded the degree. The National Book Trust biography records this sequence.
Think it through: Why might a student research at one institution but receive a degree from another?
Research location and degree-awarding authority can differ. In Sohonie’s case, the sources say she worked at IISc and submitted the work to Bombay University.
Great to know: plants, nutrition and the “first”
What did her Cambridge PhD examine?
Sohonie completed a PhD at Cambridge in 1939. Her research examined cytochrome c in plant tissue and its role in plant respiration. It did not mark the first discovery of cytochrome c itself. A 1939 Nature paper by R. Hill and K. Bhagvat is titled “Cytochrome Oxidase in Flowering Plants”. The National Book Trust biography gives her thesis title as “Cytochrome C and its Role in the Respiration of Plant Tissue”.
Cytochrome c: an electron-carrying protein in cellular respiration.
Plant respiration: cells release usable energy through chemical reactions. Sohonie’s work examined how cytochrome activity appears in plant tissue.
The paper added evidence about cytochrome in plant tissue. It connected laboratory biochemistry with a question about how plant cells work.
What was significant about studying cytochrome in plants?
It extended research on respiration to plant tissue. Sohonie’s thesis examined this process; it was not the first discovery of cytochrome c itself.
How did her research connect to nutrition?
Later, Sohonie studied Neera, the sap collected from toddy-palm inflorescences. The Institute of Science biography reports vitamin A, vitamin C, and iron in Neera. It also associates her work with dietary studies involving malnourished children and pregnant women in tribal communities. The same biography reports a Rashtrapati Award for this work.
These accounts describe research context, not a proven cure. They do not provide study methods, participant numbers, or measured effect sizes. The careful conclusion is that Sohonie investigated a locally available food’s nutritional value. Read the institutional account of her Neera research.
Explain it back: Why does the Neera story connect biochemistry with public nutrition?
Sohonie used biochemical research to examine nutrients in a locally available palm sap. The reported dietary studies considered its possible role in diets, without proving that it cured malnutrition.
What does her “first” distinction mean?
Sohonie is commonly described as the first Indian woman to earn a PhD in a scientific discipline. Keep the wording tied to a PhD. IISc notes that botanist Janaki Ammal earned a DSc from the University of Michigan in 1931. The degrees have different titles, so avoid broadening Sohonie’s distinction to “first Indian woman with any doctorate.” IISc explains this distinction.
For exam questions, keep the qualifier and degree title together. This avoids merging separate achievements into one broad claim.

Remember this
- Sohonie faced gender-based refusal before entering IISc research.
- She researched food proteins at IISc; Bombay University awarded her MSc in 1936.
- Her 1939 Cambridge PhD examined cytochrome c in plant tissue and plant respiration.
- Her later Neera work connected biochemistry with public nutrition.
- Use “first Indian woman to earn a science PhD” with its degree-specific wording.
