"At the dawn of the twentieth century, the United States was reeling from the effects of rapid urbanization and industrialization, and the legal system in particular began to buckle under the weight of its anachronism. Porwancher argues that in the midst of this crisis, John Henry Wigmore single-handedly modernized the jury trial with his treatise on evidence, an encyclopedic work that dominated the conduct of trials and inspired generations of jurists--among them Holmes, Cardozo, and Frankfurter--to reshape American law."-- Law and Social Inquiry "[The book] will become the standard work on the subject, and more than that, will contribute to emerging clarity in the field of early twentieth-century legal ideas more broadly."-- Noah Feldman , Professor of Law, Harvard Law School, author of Cool War: The Future of Global Competition "It evidences a close reading of Wigmore's work and extensive work in the archives at Harvard and Northwestern, bringing to light a good deal of new material on the connections among important figures in 'legal modernism.'"-- Robert P. Burns , Professor of Law, Northwestern University School of Law, author of A Theory of the Trial.
