'This outstanding book offers fresh insights on financial crises, J. P. Morgan, and business history. Its research exploits long-neglected archives, novel analysis, and masterful synthesis of events. And it highlights the impacts of information, collective action, social networks, tactics, precedents, and the willingness of leaders to risk private loss - all in combatting financial crises. The lessons are bracing and highly relevant to the present day.' Robert F. Bruner, Professor Emeritus and Dean Emeritus, University of Virginia, and co-author of The Panic of 1907: Heralding a New Era of Finance, Capitalism, and Democracy
