Nicholas Kristof of the New York Times called him "one of the unsung heroes of modern times." Fazle Hasan Abed was a mild-mannered accountant who may be the most influential man most people have never even heard of. A former finance executive with almost no experience in relief aid, he founded BRAC, originally the Bangladesh Rehabilitation Assistance Committee, in 1972, aiming to help a few thousand war refugees. A half century later, BRAC is by many measures the largest nongovernmental organization in the world—and by many accounts, the most effective anti-poverty program ever. His methods changed the way global policymakers think about poverty. He was revered in international development circles, yet among the wider public he remained largely unknown. His story has never been told—until now. The challenges he faced often seemed insurmountable. Abed's personal life was a tapestry of love and grief—a lover's suicide, a wife who died in his arms. He was a taciturn man with a short temper that erupted on rare occasions. Many of his ventures failed, but Abed persevered. This book is also the biography of an idea—the idea that hope itself has the power to overcome poverty. This is the story of a man who lived a life of complexity, blemishes and all, driven by the conviction that in the dominion of human lives, hope will ultimately triumph over fate.
