Nathan Leopold

Nathan Freudenthal Leopold Jr. and Richard Albert Loeb, usually referred to collectively as Leopold and Loeb, were two wealthy students at the University of Chicago who in May 1924 kidnapped and murdered 14-year-old Bobby Franks in Chicago, Illinois, United States. They committed the murder—characterized at the time as "the crime of the century"—as a demonstration of their ostensible intellectual superiority, which, they thought, enabled them to carry out a "perfect crime" and absolve them of responsibility for their actions.
