Economist. He promoted a form of state (or really expert) led capitalism that was intended to replace laissez-faire (free market) capitalism and to rescue economies from the threat of depression. These ideas, along with his charm and remarkable speaking and writing ability, made him world famous and a political figure of note.

In his personal life, he married a ballerina and was a member of the so-called Bloomsbury Group, which revered art and books, distrusted authorities, whether of church, state, or family, and led a cultivated but Bohemian lifestyle.
