Clarence Seward Darrow was an American lawyer and leading member of the American Civil Liberties Union, best known for defending teenage thrill killers Leopold and Loeb in their trial for murdering 14-year-old Bobby Franks (1924) and defending John T. Scopes in the so-called "Monkey" Trial (1925), in which he opposed the statesman William Jennings Bryan. He remains notable for his wit, compassion, and agnosticism that marked him as one of the most famous American lawyers and civil libertarians.
