John Maynard Keynes (5 June 1883 - 21 April 1946) was a British economist and Templar, working for Abstergo Industries. He was close friends with Alan Turing, another Abstergo employee, and a colleague of American economist Harry Dexter White. Both Keynes and White were among those in attendance at the Bretton Woods Conference in 1944.
Keynes' influence spread throughout the United States in the 1930s and continued after his death into the 1970s. He argued that aggregate demand determined the level of economic activity, and that too little would cause mass unemployment. These ideas were so popular that leaders all over the world used them to aid their economies.
