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—when he saw Dan Cody's yacht drop anchor over the most insidious flat on Lake Superior.
Chapter 6 · Narrator
Context
Nick interrupts the present-tense narrative to provide Gatsby's true origin story, which Gatsby told him much later. This flashback reveals that Jay Gatsby was born James Gatz, a poor young man from North Dakota who reinvented himself upon encountering the millionaire Dan Cody's yacht on Lake Superior.
Analysis
The flashback functions as the novel's definitive revelation of Gatsby's fabricated identity, with the equivocation 'really, or at least legally' immediately destabilizing the very concept of a 'true' name and suggesting that identity in this novel is always performative. The precision of 'the specific moment' frames self-invention as an instantaneous act of will rather than a gradual process, aligning Gatsby's transformation with the American myth of radical self-creation.
How to Use in Essay
Essential for essays on the American Dream as self-invention, or for arguing that Gatsby's name change represents the novel's central thesis about the constructed nature of identity in America.
