Everyday People Who Led Momentous Change

Nancy Koehn, a Harvard Business School historian, tells the life
stories of three influential leaders: the abolitionist Frederick
Douglass, the pacifist Dietrich Bonhoeffer, and the ecologist
Rachel Carson. They all overcame personal challenges to achieve and
inspire social change. In Koehn’s new book, "Forged in Crisis: The
Power of Courageous Leadership in Turbulent Times," she argues that
tomorrow's leaders of social change will come from the business
world.
