Walter Wriston was once one of the most powerful people on the planet. The chairman of the financial giant Citibank and its parent corporation, Citicorp, he was also a man with a vision. Wriston was a globalist who was deeply influenced by economist Friedrich Hayek's vision of a world in which market freedoms were the basis of individual liberty. Look closely at the burgeoning of international finance, of information networks, of logistical innovations that transformed trade. You'll find Wriston everywhere.
