Robert Newton Ford was an American outlaw who killed fellow outlaw Jesse James on April 3, 1882. He and his brother Charley, both members of the James–Younger Gang under James's leadership, went on to perform paid re-enactments of the killing at publicity events. Ford would spend his later years operating multiple saloons and dance halls in the West.

Jesse Woodson James was an American outlaw, bank and train robber, guerrilla and leader of the James–Younger Gang. Raised in the "Little Dixie" area of Western Missouri, James and his family maintained strong Southern sympathies. He and his brother Frank James joined pro-Confederate guerrillas known as "bushwhackers" operating in Missouri and Kansas during the American Civil War. As followers of William Quantrill and "Bloody Bill" Anderson, they were accused of committing atrocities against Union soldiers and civilian abolitionists, including the Centralia Massacre in 1864.
