In 1920 the Harold Pratt House was designed and erected for Mr. and Mrs. Harold Irving Pratt by the famous New York architect, William Adams Delano, of the firm Delano and Aldrich. The prestigious firm was sought out from the wealthiest of families including the Rockefellers, Astors, Vanderbilts and Whitneys for their coveted architectural styles. Only the best materials available were used in constructing the house which is reputed to have cost over a million dollars in 1920. Mr. Harold Irving Pratt was the youngest of eight children. His father, Mr. Charles Pratt, merged Pratt Astral oil with John D. Rockefeller’s Standard Oil of New Jersey during the latter part of the 19th century.
