He was skinny and dapper and handsome in a sinister sort of way, a representative of the new breed of racketeer, part thug and part businessman. And he enjoyed Capone's favor. —"Capone: The Man and the Era," by Laurence BergreenThe 27-year-old Humphreys was put into the racketeering side of the business but also carried out some killings for the mob around this time. His two most commonly known nicknames were "The Camel" and "The Hump". It has been suggested that the nickname, "The Camel", derived from his preference for wearing camel hair coats; however, a more likely explanation is that "The Camel," evolved from his other nickname, "The Hump", derived from his surname. The names given to him by his friends, however, were more revealing: "Mr. Einstein", "The Brainy Hood" and "Mr. Moneybags".
