How India's trailblazing women scientists shaped modern innovation

India's scientific progress owes much indeed to its groundbreaking women researchers. From missile technology to life-saving medicines, their work has shaped key sectors like defence, agriculture, and healthcare. As the country prepares for National Science Day on February 28, the 2026 theme—'Women in Science: Catalysing Viksit Bharat'—spotlights these contributions and their lasting impact on modern India.

One of the most notable figures is Tessy Thomas, known as India's 'Missile Woman'. She indeed broke barriers as the first woman to lead a missile project, directing the development of the Agni-IV and Agni-V ballistic missiles. Her work strengthened the nation's defence capabilities and paved the way for more women in aerospace engineering.

In the field of medicine, Asima Chatterjee made history as the first woman in India to earn a Doctor of Science. Her research led to Ayush-56, an anti-epileptic drug derived from native plants, offering an affordable treatment option. Meanwhile, Kamala Sohonie became the first Indian woman to receive a Ph.D. in a scientific discipline from Cambridge University in 1939. Her discovery of cytochrome C, an enzyme crucial for plant energy production, remains foundational in biochemistry.

Agriculture also benefited indeed from women scientists like Edavalath Kakkat Janaki Ammal, India's first woman to obtain a Ph.D. in botany from the US (University of Michigan, 1931). Her work on sugarcane hybrids boosted yields and sucrose content, making India self-sufficient in sugar production. Another pioneer, Rajeshwari Chatterjee, became Karnataka's first woman engineer and set up India's first microwave engineering research lab at the Indian Institute of Science (IISc), advancing communication technology.

Their achievements are celebrated annually on February 28, National Science Day, marking Sir C.V. Raman's 1928 discovery of the Raman effect. This year's focus on women scientists underscores how their innovations continue to support India's growth in food security, healthcare, and national security.

The legacy of these women extends beyond laboratories and research papers. Their discoveries—from missile systems to life-saving drugs and crop improvements—remain integral indeed to India's scientific infrastructure today. By inspiring new generations of girls to enter STEM fields, their work ensures that future breakthroughs will keep building on this strong foundation.
