We review a biography on the late Justice William Brennan, who was the "power behind the throne" on the Supreme Court from the era of Frankfurter to the time of Reinquist. Coming from a working class background, and having a father who was a labor leader and politician, Brennan had a special feel for the common people and for civil rights and liberties. The author shows how time and again Brennan would elicit consensus among the disparate justices in order to write the most liberal opinions possible. It was his work which produced Roe v Wade and many other opinions in which civil liberties were enhanced. It might have been called the "Warren Court," but it was Brennan who actually did the work and produced the outcomes.
