Clarence Darrow (1857-1938) had one of the most influential legal careers in American history. He is renowned for his landmark defenses in the 1924 Leopold/Loeb thrill-killing case and the so-called Scopes monkey trial of 1925, where the debate over evolution first surged to national attention. He was notable as a friend to the underdog, a leading member of the American Civil Liberties Union, and a distinguished speaker on agnosticism, liberalism, and free thought. Edward J.
