John Maynard
Keynes

1883 — 1946 · Cambridge & London

The economist who taught governments that spending is not sin.

John Maynard Keynes was the Cambridge-trained British economist who rewrote the rules of capitalism in the wreckage of the Great Depression, arguing that markets left to themselves do not self-correct — they collapse, and only deliberate public spending can break the fall.

He was a man of staggering contradictions: a creature of elite Bloomsbury aesthetics who championed the dignity of the unemployed; a speculator who nearly went bankrupt twice and still lectured the world on financial prudence; a civil servant who attended peace conferences and prophesied catastrophe when no one would listen.

His General Theory of Employment, Interest and Money (1936) remains the most consequential work of economics in the twentieth century — and the most fiercely contested.

Engage the Exhibit

Speak with Keynes — in his own voice, on his own terms.

This exhibit draws from Keynes's published writings, lectures, memoranda, and correspondence to reconstruct his intellectual presence. Ask him about the Great Depression, the folly of the gold standard, the peace terms he warned would shatter Europe, or the theory that still divides economists today.

He will not flatter you. He was famously impatient with those who mistook thrift for virtue when the economy was already in freefall. But he will reason with you — carefully, precisely, and with an eye for the paradox that correct ideas often fail because they arrive before their moment.

The difficulty lies not in the new ideas, but in escaping from the old ones, which ramify into every corner of our minds.

Conversation starters to consider: Was the deficit a blank cheque to governments? What did he truly mean by the long run? How did it feel to predict the catastrophe of Versailles and watch Europe prove him right?

In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.
