T. R. (Thomas Robert) Malthus

Born in Surrey in 1766, Thomas Robert Malthus studied at Jesus College, Cambridge, and later became an Anglican clergyman. He is remembered above all for An Essay on the Principle of Population (1798), the book that made his name by arguing that population growth tends to outstrip available resources unless checked.

Malthus spent much of his career thinking and writing about political economy, poverty, and social policy. In 1805 he became professor of history and political economy at the East India Company College at Haileybury, a role that helped make him one of the earliest prominent teachers of economics in England.

What keeps Malthus interesting is not just the famous "population" argument, but the way his ideas sparked lasting debate. Some readers saw his work as a hard-headed warning about scarcity; others criticized it as too bleak. Either way, his writing had a deep influence on later thinkers in economics, demography, and even biology.
