4. Why He Received the Award
Prof. Sukh Dev was honored with the Padma Bhushan in recognition of his monumental contributions to chemical sciences and industrial research. His deep-dive investigations into Indian medicinal flora—most notably isolating and characterizing active constituents like guggulsterone from Commiphora wightii (Guggulu)—paved the way for novel cholesterol-lowering pharmaceutical formulations. His work successfully combined modern structural organic chemistry with the validation of traditional Ayurvedic medicine.
5. Early Life
Born in Chakwal (in undivided Punjab) to Hari Chand Lala and Maya Vanti, Sukh Dev grew up in an environment that valued academic discipline. His early life was shaped against the backdrop of a changing subcontinent, experiencing the Partition era which shifted his professional base permanently to independent India, where he channeled his resilience into an unyielding passion for chemical sciences.
6. Education

- Doctoral Studies: Joined the Indian Institute of Science (IISc), Bangalore, working under the legendary natural products chemist Prof. Praphulla Chandra Guha, and earned his Ph.D. in 1948.
- Post-Doctoral & Advanced Degrees:
- Conducted post-doctoral research at the Massachusetts Institute of Technology (MIT) with Prof. John D. Roberts.
- Earned a prestigious Doctor of Science (D.Sc.) degree from IISc in 1960.
7. Career Journey
- Early Academic Roles: Served as a research associate, lecturer, and senior research fellow at IISc, Bangalore (1951–1959), which included a brief stint as a research associate at the University of Illinois under Prof. Elias James Corey.
- National Chemical Laboratory (NCL, Pune): Joined NCL in 1960 as the Head of the Organic Chemistry (Natural Products) Division, rising to Deputy Director, and serving until 1974.
- Malti-Chem Research Centre: Appointed as Director of the Malti-Chem Research Centre in Nandesari, Gujarat (1974–1988), where he focused heavily on industrial research and technology development.
- Late Academic Chapters: Served as the INSA S.N. Bose Research Professor at IIT Delhi (1989) and later as a Visiting Professor at the Dr. B.R. Ambedkar Centre for Biomedical Research (ACBR), University of Delhi (1994).
8. Major Achievements
- Terpenoid Chemistry & Structural Elucidations: Authored path-breaking work on sesqui- and diterpenoids, discovering brand-new chemical skeletal types and proposing the Absolute Stereochemistry Biogenetic Rule.
- Chromatographic Innovation: Pioneered the use of silver nitrate-silica gel thin-layer chromatography for separating olefins (1962), a technique adopted globally in organic chemistry laboratories.
- Ayurveda-to-Modern Medicine Translation: Investigated ancient plant resources like Guggulu, leading to the development of guggulsterones used for managing lipid profiles and cholesterol.
- Patents & Publications: Authored over 290 research papers, secured 55 patents, and published 10 authoritative books (including Prime Ayurvedic Plant Drugs).
9. Contribution to the Nation
Prof. Sukh Dev revolutionized how India utilized its indigenous natural and botanical wealth. By marrying classical chemical analysis with industrial applications, he helped build domestic capabilities in chemical synthesis and drug manufacturing. Furthermore, as an institutional leader at NCL and Malti-Chem, he demonstrated how scientific research could directly feed into national economic growth and self-reliance.
