A recognized, fascinating, and much-cited classic of judicial biography and Supreme Court insight is now available in a new reprint edition--featuring embedded page numbers from prior printings to maintain continuity in citations and referencing. Felix Frankfurter was perhaps the most influential jurist of the 20th century--and one of the most complex men ever to sit on the U.S. Supreme Court. Mysteries and apparent contradictions abound. A vibrant and charming friend to many, why are his diaries so full of vitriol against judicial colleagues, especially Douglas and Black? An active Zionist, why did he so zealously enjoy the company of Boston Brahmins, whose snobbery he detested? Most puzzling of all: why did someone known before his appointment to the Court as a civil libertarian--even a radical--become our most famous and persistent advocate for austere judicial restraint? In answering these and other questions, this pathbreaking biography of Frankfurter explores the personality of the man as a key to understanding the Justice. Harry Hirsch sees in Frankfurter's fascinating and complex persona a clue to the biggest mystery of all: the contrast between the brilliant and ambitious young immigrant rising by his intellect and charm to leadership in U.S. academic and political life; and the judge, equally brilliant, but increasingly isolated, embittered, and ineffective.
