Renowned Nuclear Scientist and Activist M.P. Parameswaran Passes Away at 92
Former nuclear scientist, writer, and prominent people’s science movement activist M.P. Parameswaran passed away in Thrissur, Kerala, on Tuesday, August 11, 2026, at the age of 92.
What Happened
Born on January 18, 1935, in Thrissur district, Parameswaran earned a Bachelor’s Degree in Engineering from the College of Engineering, Thiruvananthapuram, in 1956, and later earned a PhD in Nuclear Engineering from the Moscow Power Institute in 1965. He served as a scientist with the Bhabha Atomic Research Centre (BARC) in Mumbai from 1957 until 1975. After concluding his career at BARC, he committed himself entirely to activism and became a central figure in the Kerala Sasthra Sahithya Parishad (KSSP).
Key Highlights
- Scientific and Academic Career: Held an engineering doctorate from the Moscow Power Institute and worked as a nuclear scientist at BARC for 18 years.
- People’s Science Leadership: Stood as an early and prominent leader of the KSSP and helped establish the All India People’s Science Network (AIPSN), serving in roles as its secretary and later its president.
- Literacy Campaigns: Aided the development of the Bharat Gyan Vigyan Samiti, an organisation that coordinated widespread literacy initiatives across the country.
- Prolific Author: Penned multiple award-winning popular science books in English and Malayalam covering areas such as atomic energy, astronomy, radioactivity, mathematics, ecology, and political science.
- The ‘Fourth World’ Debate: Authored the book Fourth World, which outlined a framework based on decentralized democracy, economic production, and freedom from consumerism. The concept sparked extensive internal debate and led to his expulsion from the CPI(M) in February 2004 for party indiscipline.
Why This Matters
Parameswaran was a vital influence on mass science education, rural development, environment, and literacy initiatives throughout India. His transition from high-level atomic research to grassroots science communication helped shape institutions like the KSSP, AIPSN, and Bharat Gyan Vigyan Samiti, while his socio-economic writings provoked major ideological discussions within India’s political and activist spheres.
