John Maynard Keynes, 1st Baron Keynes (5 June 1883 - 21 April 1946) was a British economist whose ideas, called Keynesian economics, have had a major impact on modern economic and political theory as well as on many governments' fiscal policies. He advocated interventionist government policy, by which the government would use fiscal and monetary measures to mitigate the adverse effects of economic recessions, depressions and booms. Even Keynes' critics call him the greatest and most influential economist of the 20th century. For this reason, he is known as "the father of modern economics." Keynes' advice on ending the Great Depression was rejected. President Roosevelt tried countless other approaches, all of which failed. Then, in seven short years, under massive Keynesian spending, the U.S. went from the greatest depression it has ever known to the greatest economic boom it has ever known. The success of Keynesian economics was so resounding that almost all capitalist governments around the world adopted its policies. Time Magazine named Keynes one of the 100 most influential people of the 20th century, on his Keynesian Theory state.. "His radical idea that governments should spend money they don't have may have saved capitalism". He is one of the fathers of modern theoretical macroeconomics.
