Nancy Koehn is a historian at the Harvard Business School where she holds the James E. Robison chair of Business Administration. Koehn’s research focuses on how leaders, past and present, craft lives of purpose, worth, and impact.

Her latest book, Forged in Crisis: The Power of Courageous Leadership in Turbulent Times is an enthralling historical narrative filled with critical leadership insights that will be of interest to a wide range of readers—including those in government, business, education, and the arts. Forged in Crisis spotlights five masters of crisis: polar explorer Ernest Shackleton; President Abraham Lincoln; legendary abolitionist Frederick Douglass; Nazi-resisting clergyman Dietrich Bonhoeffer; and environmental crusader Rachel Carson.

What do such disparate figures have in common? Why do their extraordinary stories continue to amaze and inspire? In delivering the answers to those questions, Nancy Koehn offers a remarkable template by which to judge those in our own time to whom the public has given its trust.

Significantly, as we follow each leader’s against-all-odds journey, we begin to glean an essential truth: leaders are not born but made. In a book dense with epiphanies, the most galvanizing one may be that the power to lead courageously resides in each of us.
