This rags-to-riches biography tells the story of David Bussau, once an orphan, now a millionaire businessman and founder of Opportunity International, one of the world's largest aid organizations. The main emphasis in this volume is on Bussau's humanitarian work that revolutionized overseas aid through the principles of microenterprise development, in which small repayable loans are offered to the poor so they can start and grow their own small businesses.
