Muhammad Yunus started a movement that has lifted millions out of poverty. When he formed the Grameen Bank in 1983 and started giving out microloans, Yunus bridged the divide between business and social needs. In this audio lecture, he describes how he created microcredit, collateral-free lending, and began offering other business services to the poor. Yunus lays out the path to his extraordinary vision and success, which is driving global social change.
