Shanti Swaroop Bhatnagar

Sir Shanti Swaroop Bhatnagar was an eminent Indian physical chemist and visionary scientific organizer whose tireless leadership built the scientific infrastructure of modern independent India. After studying chemistry at Forman Christian College in Lahore and completing his Doctor of Science at University College London under Frederick Donnan, Bhatnagar served as professor at Banaras Hindu University and Panjab University in Lahore.

Bhatnagar made foundational contributions to colloid chemistry and magneto-chemistry, co-inventing the Bhatnagar-Mathur magnetic balance, one of the most sensitive magnetic susceptibility measuring devices of its era. Working closely with Prime Minister Jawaharlal Nehru, Bhatnagar served as the inaugural Director-General of the Council of Scientific and Industrial Research (CSIR). In a remarkable decade of nation-building, he established twelve major national laboratories across India—including the National Physical Laboratory and National Chemical Laboratory. India's highest scientific accolade, the Shanti Swaroop Bhatnagar Prize, is named in his honor.
