Step-by-step explanation:
Jay Gatsby's real name is James Gatz. This piece of information is revealed in F. Scott Fitzgerald's novel The Great Gatsby, in which the title character is explored as a complex individual, distinct from other figures of his time. Despite any impressions of grandeur and mystery surrounding the character, we learn that his beginnings were much more humble than many in his social circle would assume.
Fitzgerald's work is known for its intricate character developments and layers of symbolism. While 'Jay Gatsby' is the persona he created, the character was born as James Gatz.

The complicated and ultimately tragic story of Jay Gatsby reflects the unique and personal journeys of individuals during the 1920s.
