235 Middle Neck Road was purchased by Mary Harriman Rumsey in 1923. Mrs Rumsey was the founder of Junior League of the City of New York and daughter of EH Harriman, the railroad magnate, as well as the sister of W. Averell Harriman, former Governor of New York. She hired McKim, Mead and White as architects to design the French Normandy style castle, which was completed in 1928. Over the years Mrs Rumsey hosted many fabulous individuals at the estate, including her dear friend, F. Scott Fitzgerald. It is rumored that the time he spent at the house helped to inspire the writing of the novel, The Great Gatsby, and the area on the Gold Coast of Long Island is largely considered to be "Gatsby's East Egg".
