In The Great Gatsby (1925), F. Scott Fitzgerald explains where Jay Gatsby came from. “James Gatz—that was really, or at least legally, his name. He had changed it at the age of seventeen and at the specific moment that witnessed the beginning of his career.”
His parents were farm people, “shiftless and unsuccessful.” Fitzgerald writes that Gatsby’s imagination “had never really accepted them as his parents at all.” Then he gives the line that readers remember: “The truth was that Jay Gatsby, of West Egg, Long Island, sprang from his Platonic conception of himself.”
