One bounty jumper became particularly famous. Adam Worth became an international thief, with the theft of Thomas Gainsborough's painting "Duchess" being his most famous crime. He would become known as the "Napoleon of Crime", a label Sir Arthur Conan Doyle would borrow when creating the character Professor Moriarty, whom Doyle loosely based on Worth. According to William Pinkerton, Worth did actually fight once, for the Union in the Battle of the Wilderness, and once collected a $30 Confederate bounty, only to eventually fight for the Union. Pinkerton further said that Worth did what he did due to greed and lack of patriotism, not for cowardice.
