Just watched a documentary clip about the Solar Mamas program last week, grandmothers from villages wiring up solar panels with their own hands. Read the news this morning and just sat with my coffee for a minute. 81 years old and still based in that same village in Tilonia.

Sanjit "Bunker" Roy was an Indian social activist and educator who founded the Barefoot College in the Rajasthan village of Tilonia. Built on the conviction that villagers without formal schooling could master technical skills and solve their own problems, it trained more than three million people as solar engineers, teachers, midwives, weavers, architects and health workers. He died at his home in Tilonia on 10 November 2026, aged 81.
He was born on 30 June 1945 in Burnpur, in what was then the Bengal Presidency of British India. He was educated at The Doon School from 1956 to 1962 and at St. Stephen's College, Delhi, from 1962 to 1967. As a young man he was one of India's best squash players: he won the national championship in 1965 and represented India at three world squash championships.
Instead of the comfortable career his background seemed to promise, he turned to rural India. After surveying water supplies in 100 drought prone areas, he set up the Social Work and Research Centre in Tilonia in 1972. Its focus moved from water and irrigation to self reliance: siting hand pumps near villages and training local people to maintain them, training paramedics, and bringing solar power to homes that depended on kerosene. The institution became known worldwide as the Barefoot College, and its programme training older, often illiterate women from poor communities in many countries as solar engineers, the so called Solar Mamas, made it famous far beyond India.
Roy also worked on policy. Appointed by Rajiv Gandhi to the Planning Commission, he proposed a code of conduct and a national council for non-governmental organisations, ideas that were fiercely opposed by those who feared they could be used to reward favoured groups. In 1983 he was the plaintiff in Roy v State of Rajasthan, in which the Supreme Court struck down a policy allowing women famine relief workers to be paid less than men.
His honours included the Jamnalal Bajaj Award in 1985, the Padma Shri in 1986, the St Andrews Prize for the Environment and recognition as a Schwab Foundation Social Entrepreneur of the Year in 2003, and the Robert Hill Award in 2009. In 2010 Time magazine named him one of the 100 most influential people in the world, and he became a popular TED speaker.
He married the activist and former civil servant Aruna Roy in 1970. He died peacefully at about 6.15 in the morning of 10 November 2026 with Aruna and others close to him at his side. The funeral was held in Tilonia that afternoon, and tributes came from across Indian public life, including the former Rajasthan chief minister Ashok Gehlot.
