William Stanley Jevons

An English economist and logician born in Liverpool in 1835, Jevons is remembered as one of the key figures behind the rise of modern economic theory. His 1871 book The Theory of Political Economy argued that value is tied to utility at the margin, helping reshape economics in a more analytical and mathematical direction.

His life ranged far beyond the study. After leaving University College London before finishing his degree, he worked at the Sydney Mint in Australia, where he developed interests in political economy, science, and social questions. Back in Britain, he wrote on money, statistics, logic, and industrial society, and he was elected a Fellow of the Royal Society.

Jevons also had a sharp eye for the long-term consequences of economic growth. In The Coal Question he warned that greater efficiency in using a resource does not necessarily reduce total consumption, an idea later associated with the "Jevons paradox." He died in 1882, but his clear, curious way of linking economics with real-world problems has kept his work alive.
