Muhammad Yunus pioneered microcredit and founded Grameen Bank to provide loans to poor people without collateral. While teaching economics, he saw people dying from poverty and wanted to address this. He started a microcredit program in the 1970s and founded Grameen Bank in 1983 to provide small, low-interest loans to help the poor lift themselves out of poverty through work. Yunus emphasized empowering women and community support through programs like village phones. His work achieved significant success in reducing poverty and he received numerous honors including the 2006 Nobel Peace Prize.
