Dr. Asima Chatterjee
Dr. Asima Chatterjee was a renowned Indian chemist known for her work in organic chemistry and phytomedicine. She is best known for her research on anti-epileptic and anti-malarial drugs using plant-based compounds. One of her major contributions was the development of the anti-malarial drug ‘Ayush-56’ from indigenous plants. Her research laid the foundation for modern herbal medicine in India. She was the first woman to receive a Doctorate of Science from an Indian university and the first woman scientist to be elected as the General President of the Indian Science Congress. Her groundbreaking work combined traditional Indian knowledge with modern science, helping to treat diseases through natural remedies. Her achievements continue to inspire women in science.
Dr. Yellapragada Subbarao
Dr. Yellapragada Subbarao was an Indian biochemist whose discoveries have saved millions of lives. He developed several life-saving antibiotics, including tetracycline, and played a major role in discovering the role of adenosine triphosphate (ATP) in energy transfer within cells. He also introduced diethylcarbamazine (DEC), a drug that treats filariasis, a major tropical disease. Despite facing many hardships and lack of recognition in his early career, he made significant contributions while working in the United States. His research influenced cancer treatment, nutrition, and infectious disease control. Subbarao’s work bridged Eastern and Western science, and though not widely known, his legacy lives on in the life-saving drugs and methods still used in medicine today.
