M.P. Parameswaran, one of India’s most respected nuclear scientists and a leading Marxist thinker from Kerala, passed away on August 11, 2026, at his home in Thrissur. He was 92 years old. Known simply as “MP” to generations of activists, students, and readers across Kerala, Parameswaran was that rare figure who gave up an elite scientific career to spend his life bringing science, rational thought, and social justice to ordinary villagers.

His death marks the end of an era for the people’s science movement in India — a movement he helped build almost from the ground up. Tributes have poured in from political leaders, scientists, writers, and activists across the state, remembering him as a man who chose conscience over comfort.

Early Life and Education

Born on January 18, 1935, in the village of Kiralur in Kerala’s Thrissur district, Parameswaran grew up in a period when India itself was fighting for independence and searching for a scientific, modern identity. He pursued his early academic training at the College of Engineering, Thiruvananthapuram, where he earned a degree in electrical engineering.

His pursuit of higher learning later took him to the Soviet Union, where he completed a PhD in nuclear engineering at the Moscow Power Engineering Institute in 1965. This period shaped much of his later thinking, exposing him not only to nuclear science but also to the ideological currents of socialism that would come to define his political worldview.

A Career at the Heart of India’s Nuclear Programme

After returning to India, Parameswaran joined the Bhabha Atomic Research Centre (BARC), the country’s premier nuclear research institution, where he worked as a scientist from 1957 to 1975. During these years, he was closely associated with India’s early nuclear programme, contributing his expertise at a time when the country was laying the technical foundations for its atomic energy ambitions.

Between 1969 and 1973, he also served on deputation as Assistant Director of the State Institute of Languages in Kerala — an early hint of his growing interest in communication, education, and public life beyond the laboratory.

The Turning Point: Leaving BARC for the People

In 1975, Parameswaran made the decision that would define the rest of his life. He resigned from his secure, prestigious position at BARC to devote himself entirely to the Kerala Sasthra Sahithya Parishad (KSSP), a grassroots organisation founded in 1970 with the goal of spreading scientific literacy and rational thinking among ordinary citizens.

It was an unusual and, for many, an incomprehensible choice — a nuclear scientist walking away from a stable government career to work among farmers, students, and factory workers. But Parameswaran believed that science had no real value unless it reached the people who needed it most.

Under his leadership, KSSP grew from a small group of science teachers into one of the largest people’s science movements in the world, eventually counting more than 50,000 members. The organisation became a model that other Indian states would later try to replicate.

Champion of Environmental and Social Movements

Parameswaran’s influence extended far beyond classrooms and lecture halls. He believed development decisions should never be made without the informed consent of the people who live with their consequences. This belief shaped several major public campaigns:

• Save Silent Valley movement (late 1970s–80s): Played a central role in stopping a hydroelectric dam that would have submerged a rare evergreen forest in Palakkad district.
• Athirappilly hydroelectric project opposition: Continued to question large dam projects on ecological and social grounds.
• Anti-unsafe-drugs campaign: Pushed for stricter scrutiny of harmful pharmaceuticals sold in India.
• Total literacy campaigns: Worked to make basic literacy accessible across Kerala’s villages.
• Rural energy efficiency: Promoted cleaner, more efficient cooking stoves for rural households.

Building a National Movement

Parameswaran’s ambitions were never limited to Kerala alone. His key contributions at the national level include:

• 1987 — Bharat Jan Vigyan Jatha: Served as Convener of the National Organising Committee for this massive nationwide science communication campaign.
• All India People’s Science Network (AIPSN): Helped found this common platform, uniting grassroots science movements from West Bengal, Andhra Pradesh, Karnataka, and other states.
• 1990 — Bharat Gyan Vigyan Jatha: Helped organise this campaign in support of India’s National Literacy Mission.
• Bharat Gyan Vigyan Samiti (BGVS): This effort eventually led to the formation of BGVS, which coordinated one of the largest literacy drives in Indian history.

The Fourth World: A Marxist Thinker Ahead of His Time

Beyond his scientific and organisational work, Parameswaran was a serious political theorist. He is best remembered in Left intellectual circles for his “Fourth World” theory, laid out in his book Fourth World: Dream and Reality. The theory proposed a socialist model built on the decentralisation of political and economic power, ecological sustainability, and a rejection of unchecked consumerism — ideas that many observers compared to Gandhian concepts of Gram Swaraj and Swadeshi.

The Fourth World theory triggered sharp internal debate within the Communist Party of India (Marxist), or CPI(M). Party leadership ultimately rejected his position, and Parameswaran was expelled from the CPI(M) in 2004. Yet, according to those close to him, the split was never bitter. Parameswaran understood the party’s reasoning even as he disagreed with it, and the CPI(M), in turn, recognised that his critique came from within the Left rather than as a rejection of socialism itself. He continued to be respected as a Marxist thinker long after his formal expulsion.

A Prolific Author

Parameswaran was also a gifted writer, authoring numerous books in both Malayalam and English on subjects ranging from nuclear science and technology policy to socialism and rural development. Over his career he wrote close to 30 books and more than 300 articles across various periodicals, making complex scientific and political ideas accessible to ordinary readers. His writing earned him early recognition, including the Books for Neoliterates Award in 1962, the Basic and Cultural Literature Award in 1964, and the Children’s Literature Award in 1984. In 2022, the Government of Kerala honoured him with the Kerala Sree Award, the state’s third-highest civilian honour.

Tributes and Legacy

Following news of his passing, condolences came in from across Kerala’s political and cultural spectrum. Kerala Chief Minister V.D. Satheesan and senior CPI(M) leader Pinarayi Vijayan both paid tribute to him, describing him as someone who gave up scientific privilege to bring rational thought closer to ordinary citizens. He is widely regarded as one of the founding figures of India’s people’s science movement — a legacy that reaches classrooms, village reading rooms, and environmental campaigns across the country.

Parameswaran’s life stands as a rare example of a scientist who chose activism over comfort, and public service over personal advancement. He believed, until the very end, that science and democracy were inseparable — that ordinary people had both the right and the capacity to question power, technology, and the direction of development in their own lives.
