Judge Richard Posner is one of the great legal minds of our age, on par with such generation-defining judges as Holmes, Hand, and Friendly. A judge on the US Court of Appeals for the Seventh Circuit and the principal exponent of the enormously influential law and economics movement, he writes provocative books as a public intellectual, receives frequent media attention, and has been at the center of some very high-profile legal spats. He is also a member of an increasingly rare breed--judges who write their own opinions rather than delegating the work to clerks. Now, for the first time, this fascinating figure receives a full-length biographical treatment. In Richard Posner, William Domnarski examines the life experience, personality, academic career, jurisprudence, and professional relationships of his subject with depth and clarity. Domnarski has had access to Posner himself and to Posner's extensive archive at the University of Chicago. In addition, Domnarski was able to interview and correspond with more than two hundred people Posner has known, worked with, or gone to school with over the course of his career. Richard Posner is a comprehensive and accessible account of a unique judge who, despite never having sat on the Supreme Court, has nevertheless dominated the way law is understood in contemporary America.
