In this biographical study of the only American ever to have been both President and Chief Justice of the United States, Jonathan Lurie reassesses William Howard Taft's multiple careers, which culminated in Taft's election to the presidency in 1908 as the chosen successor to Theodore Roosevelt. By 1912, however, the relationship between Taft and Roosevelt had ruptured. Lurie re-examines the Taft–Roosevelt friendship and concludes that it rested on flimsy ground. He also places Taft in a progressive context, taking Taft's own self-description as 'a believer in progressive conservatism' as the starting point. At the end of his biography, Lurie concludes that this label is accurate when applied to Taft.

“This lucid, fascinating, and beautifully written account invites us to reconsider the place in history of William Howard Taft. Professor Lurie covers Taft’s career up to the point when he achieved his life's goal: the Supreme Court. The book is a superb achievement—a major study of an important and often misunderstood figure in American political and legal history.” —Lawrence M. Friedman, Stanford Law School

“This well-written and engaging account of Taft’s relationship with Theodore Roosevelt and his career up to 1921 (the first volume, of a planed two-volume study of Taft) constitutes a significant revision of the literature. Lurie demonstrates that Taft was, as he claimed to be, an important ‘progressive conservative’ who achieved and protected more ‘progressive’ measures than had Roosevelt, while simultaneously defending the Supreme Court’s role and authority. A tour de force.”—Peter Karsten, University of Pittsburgh

“In this pithy and engaging study of William Howard Taft’s political career, Jonathan Lurie argues convincingly that Taft was more progressive than previous historians have recognized and that Taft accurately characterized himself as a progressive conservative. Lurie demonstrates that Taft’s vision of a vigorous federal role in promoting the public interest inspired his progressive policies on tariff reform, conservation of natural resources, labor, federal administration, and antitrust enforcement. By explaining why Taft’s presidency was much more than a mere interlude between the progressive presidencies of Theodore Roosevelt and Woodrow Wilson, Lurie’s superb book should kindle greater appreciation for Taft among historians and general readers alike.” —William G. Ross, Cumberland School of Law, Samford University

“For too many years, William Howard Taft’s one term as president has been dismissed, along with him, as a failure, overshadowed by the two men who came before and after him. Jonathan Lurie’s lucid re-examination of Taft’s presidency will give everyone pause for thought, and historians will have to take another look at the Taft White House in terms of Taft’s own description of himself as a ‘progressive conservative.’ A very well done book.” —Melvin I. Urofsky, Virginia Commonwealth University
