John Maynard Keynes was an English economist whose work reset how governments think about recessions, employment, and public spending. In The General Theory of Employment, Interest and Money, published in February 1936, he argued that total demand in an economy, not the price of labour, sets the level of employment, and that a market can settle into a lasting slump with millions out of work. That claim gave macroeconomics its modern shape and made a case for active government policy during downturns. Keynes was also a public figure well beyond the lecture hall: a Treasury official, a critic of the 1919 peace settlement, and the chief British voice at the 1944 conference that built the postwar financial order.
Keynes was born on 5 June 1883 in Cambridge, England, into an academic household. His father, John Neville Keynes, lectured in logic and political economy at the University of Cambridge, and his mother, Florence Ada Keynes, was a social reformer who later became mayor of Cambridge. He was educated at Eton College and then at King's College, Cambridge, where he read mathematics and graduated in 1905, as recorded in the Wikipedia biography. At Cambridge he was taught by the economists Alfred Marshall and Arthur Pigou, and drew closely on the philosophy of G. E. Moore.
After graduating he joined the civil service and worked at the India Office in London, an experience behind his first book, Indian Currency and Finance (1913). He soon returned to Cambridge to lecture, and in 1911 became editor of The Economic Journal, a post he held for more than thirty years. During the First World War he served at the Treasury, and in 1919 he attended the Paris Peace Conference as its senior representative. He resigned over the severity of the reparations imposed on Germany and set out his objections in The Economic Consequences of the Peace (1919), which sold widely and made his name.
The Great Depression of the 1930s left classical economics struggling to explain why unemployment stayed high year after year. The prevailing view held that markets would return to full employment on their own, and that wage cuts would restore jobs. Keynes disagreed. He argued that cutting wages in a slump would only reduce incomes, spending, and demand further, deepening the trouble.
His argument appeared in full in The General Theory of Employment, Interest and Money in 1936. Keynes made aggregate demand, the combined spending of households, firms, and government, the driver of output and jobs, and showed that an economy could rest in equilibrium well short of full employment. When private demand falls away, he held, government can step in with spending and investment to fill the gap, an approach that came to be called Keynesian economics. The book introduced ideas still taught today, among them the consumption function, the multiplier, and liquidity preference, and it moved macroeconomics to the centre of the discipline.
Keynes's ideas guided economic policy across the industrial world for a generation after 1945, a period of steady growth and low unemployment. His influence also shaped institutions. In July 1944 he led the British delegation to the Bretton Woods Conference in New Hampshire, where delegates from 44 nations designed the postwar monetary system. Keynes chaired the commission that drafted the plan for the International Bank for Reconstruction and Development, and although his proposal for an International Clearing Union lost out to the American plan, the conference created the International Monetary Fund and the World Bank. Britain had honoured him as Baron Keynes in 1942.
From the 1970s his approach lost ground to monetarist and free-market thinking, which questioned whether government spending could manage demand without stoking inflation. The 2008 financial crisis brought his arguments back into wide use, as governments turned to stimulus spending to steady failing economies. Keynes died at Tilton, in Sussex, on 21 April 1946.
Keynes changed how ordinary people understand recessions and the choices open to their governments, and he wrote in prose meant to be read, not just cited. We keep his page because ideas that shape daily life deserve a clear and lasting record.
