Marriner Stoddard Eccles was an American banker, economist, and member and chairman of the Federal Reserve Board.
Eccles was known during his lifetime chiefly as having been the Chairman of the Federal Reserve under President Franklin D. Roosevelt. He has been remembered for having anticipated and supporting the theories of John Maynard Keynes relative to "inadequate aggregate spending" in the economy which appeared during his tenure. As Eccles wrote in his memoir Beckoning Frontiers:
As mass production has to be accompanied by mass consumption, mass consumption, in turn, implies a distribution of wealth ... to provide men with buying power. ... Instead of achieving that kind of distribution, a giant suction pump had by 1929-30 drawn into a few hands an increasing portion of currently produced wealth. ... The other fellows could stay in the game only by borrowing. When their credit ran out, the game stopped.
