James Horace Harding was born to an influential publishing family in 1863. He entered the banking world and moved up through connections on his wife's side. Harding served as a director for multiple entities including American Express and numerous railway trusts. Harding enjoyed art collecting and spent time cultivating the Frick collection.

Harding was extremely influential in Long Island and supported Robert Moses' "Great Parkway Plan" to build a highway from Queens Blvd. to Shelter Rock in Nassau County. He also supported the Northern State Parkway and construction of the Long Island Expressway. His support of new roads happened to coincide with his desire for an easier pathway to his country club.

Harding died at 65 from influenza and blood poisoning.
