After the birth of their child, the Fitzgeralds moved to Great Neck, New York , on Long Island , in October 1922. The town was used as the scene of The Great Gatsby .  Fitzgerald's neighbors in Great Neck included such prominent and newly wealthy New Yorkers as writer Ring Lardner , actor Lew Fields , and comedian Ed Wynn .  These figures were all considered to be " new money ", unlike those who came from Manhasset Neck or Cow Neck Peninsula , places which were home to many of New York's wealthiest established families, and which sat across the bay from Great Neck. This real-life juxtaposition gave Fitzgerald his idea for "West Egg" and "East Egg". In this novel, Great Neck (King's Point) became the "new money" peninsula of West Egg and Port Washington (Sands Point) the old-money East Egg.  Several mansions in the area served as inspiration for Gatsby's home, such as Oheka Castle  and Beacon Towers , since demolished.
