John Maynard Keynes

Being one of the most influential economists of the 20th century, he credited a lot of famous economic theories for the world to use. Even though a well educated child, Keynes did not contribute that well for academics ,and instead joined a variety of literary pursuits and political activities.
During the inter-war years, Keynes amassed a considerable personal fortune from the financial markets and, as bursar of King's College, greatly improved the college's financial position. He became a prominent arts patron and board member of a number of companies. In 1926, he married Lydia Lopokova, a Russian ballerina.
Keynes' best-known work, 'The General Theory of Employment, Interest and Money', was published in 1936, and became a benchmark for future economic thought. It also secured his position as Britain's most influential economist, and with the advent of World War Two, he again worked for the treasury. In 1942, he was made a member of the house of lords.
During the war years, Keynes played a decisive role in the negotiations that were to shape the post-war international economic order. In 1944, he led the British delegation to the Bretton Woods conference in the United States. At the conference he played a significant part in the planning of the World Bank and the International Monetary Fund. He died on 21 April 1946.
