Nathan Freudenthal Leopold Jr. and Richard Albert Loeb, usually referred to collectively as Leopold and Loeb, were two American students at the University of Chicago who kidnapped and murdered 14-year-old Bobby Franks in Chicago, Illinois, United States, on May 21, 1924. They committed the murder – characterized at the time as "the crime of the century" – hoping to demonstrate superior intellect, which they believed enabled and entitled them to carry out a "perfect crime" without consequences.

Clarence Seward Darrow was an American lawyer who became famous in the 19th century for high profile representations of trade union causes, and in the 20th century for several criminal matters, including the Leopold and Loeb murder trial, the Scopes "monkey" trial, and the Ossian Sweet defense. He was a leading member of the American Civil Liberties Union and a prominent advocate for Georgist economic reform. Darrow was also well known as a public speaker, debater, and writer. He is considered by some legal analysts and lawyers to be the greatest lawyer of the 20th century. He was posthumously inducted into the Trial Lawyer Hall of Fame.
