ProfAmartya Sen

Amartya Sen was nine years old when the Bengal famine of 1943 killed as many as three million people in the province around him, and he noticed something that a child could see and that the economics of the time had not: nobody he knew personally starved. The dead were the landless and the labouring poor. Food, meanwhile, kept moving through the markets. The observation lodged in him, waited four decades, and became the work that changed how the world understands hunger.

Santiniketan and Presidency

He was born on 3 November 1933 on the campus of Visva-Bharati University at Santiniketan, the school founded by Rabindranath Tagore, who is said to have given him his name — Amartya, "the immortal one." His was a family of scholars, and he grew up steeped in Tagore's cosmopolitan, questioning humanism. He studied economics at Presidency College in Calcutta, then at Trinity College, Cambridge, where he took a second degree and a doctorate and was drawn into the great mid-century debates about the foundations of economics.

Re-moralising economics

Sen's career, across Cambridge, Delhi, the London School of Economics, Oxford and Harvard, amounted to a sustained effort to put ethics back at the centre of economics — to insist that the discipline was, at root, about human lives, not merely about output and efficiency. He made foundational contributions to social choice theory, extending and answering the work of Kenneth Arrow on whether the preferences of individuals can be fairly aggregated into the choices of a society. And he developed, over many years, the "capability approach," which reframed the measure of a good life: not what resources a person commands, nor even what they feel, but what they are actually able to do and be — to be nourished, to be educated, to take part in the life of their community, to move freely.

Famines and freedom

His most influential single work was Poverty and Famines (1981), which formalised the insight of his childhood. Famines, Sen argued and demonstrated with case studies, are typically not caused by a simple absence of food but by "entitlement failures" — collapses in people's ability to command food, through lost wages, ruined harvests, or spiking prices — which can occur even when overall supply is adequate. From this came one of the most consequential claims in modern social science: that no substantial famine has ever occurred in a functioning multiparty democracy with a free press, because governments answerable to voters and exposed by journalists are forced to act. The argument tied hunger directly to democracy and liberty, and it reshaped development policy worldwide.

The Human Development Index

Sen's ideas escaped the seminar room. Working with the Pakistani economist Mahbub ul Haq, he helped build the intellectual scaffolding for the United Nations Human Development Index, which since 1990 has ranked countries not by income alone but by a combination of life expectancy, education and living standards — pushing governments to measure their progress in the length and quality of their people's lives rather than in GDP alone. It is one of the rare cases of a philosopher's framework becoming a fixture of global governance.

The Nobel and after

He was awarded the Nobel Memorial Prize in Economic Sciences in 1998, "for his contributions to welfare economics," and India honoured him with the Bharat Ratna, its highest civilian award, in 1999. He served as Master of Trinity College, Cambridge — the first Asian to head an Oxbridge college — before returning to Harvard, where he has taught for much of his later career. His book The Argumentative Indian (2005) offered the diaspora a flattering and demanding self-portrait: heirs to a long tradition of public reasoning, debate and heterodoxy that predates the European Enlightenment, and a rejoinder to those who would reduce India to a single religious or cultural essence.

Why the Roll remembers him

Well into his nineties, Sen has remained the diaspora's conscience-keeper — an economist of the world's richest universities whose lifelong subject has been the world's poorest people, and a public intellectual who has never stopped arguing, in the Tagorean spirit, for tolerance, secularism and reasoned dissent. He belongs on the Roll not only for the Nobel and the honours but for what he did to the discipline itself: he insisted that the measure of an economy is the freedom and the flourishing it delivers to the least of its people, and he made that insistence rigorous enough that governments and the United Nations had to listen. The boy who watched a famine kill the poor while the markets stayed full spent the next eighty years making sure the world understood exactly why.

The survivor

Two early experiences beyond the Bengal famine shaped Sen. As a boy he witnessed the communal violence of the 1940s, watching a Muslim day-labourer die after being stabbed in a Hindu neighbourhood — a memory of how poverty forces people into fatal risk that fed his lifelong secularism. And at eighteen, as a student, he diagnosed his own oral cancer, endured harsh radiation treatment that he was told he might not survive, and lived — carrying the knowledge of mortality, and of medicine's limits for the poor, into everything he wrote.

The public intellectual and philanthropist

Sen has never confined himself to theory. With his Nobel Prize money he founded the Pratichi Trust, which works on literacy, health and gender equality in Bengal and Bangladesh, turning his ideas about capability into schools and clinics. He agreed to help revive the ancient Nalanda University in Bihar as its first chancellor, only to be pushed out amid political friction with the government he had publicly criticised — an episode that captured his willingness to pay a price for dissent. In books including Development as Freedom and The Idea of Justice, and in a stream of essays, he has argued for democracy, tolerance and reasoned public debate, and has been among the most prominent critics of majoritarian politics in contemporary India. Well into his nineties he continued to teach at Harvard and to write, the conscience-keeper of the diaspora, an economist of the world's richest universities whose lifelong subject remained the freedom and dignity of the world's poorest people.
