John Maynard Keynes
British economist (1883–1946) whose *General Theory* revolutionized macroeconomics around aggregate demand, uncertainty, and a role for public policy in deep slumps.
Keynes argued prices and wages might not adjust quickly enough to restore full employment; animal spirits drive investment; and coordinated stimulus could break vicious cycles. His ideas underpinned Bretton Woods institutions and decades of stabilization policy.
Later monetarist and rational-expectations critiques tempered Keynesian activism but never erased its imprint on crisis response.
