William Henry Beveridge, 1st Baron Beveridge, (5 March 1879 – 16 March 1963) was a British economist and Liberal politician who was a progressive, social reformer, and eugenicist who played a central role in designing the British welfare state. His 1942 report Social Insurance and Allied Services (known as the Beveridge Report) served as the basis for the welfare state put in place by the Labour government elected in 1945.
He built his career as an expert on unemployment insurance. He served on the Board of Trade as Director of the newly created labour exchanges, and later as Permanent Secretary of the Ministry of Food. He was Director of the London School of Economics and Political Science from 1919 until 1937, when he was elected Master of University College, Oxford.
Beveridge published widely on unemployment and social security, his most notable works being: Unemployment: A Problem of Industry (1909), Planning Under Socialism (1936), Full Employment in a Free Society (1944), Pillars of Security (1943), Power and Influence (1953) and A Defence of Free Learning (1959).
