John Fairfield Dryden estate altered by George B. Post c. 1899 in Bernardsville, New Jersey. Dryden was president of the Prudential Insurance Company and U.S. Senator from New Jersey from 1902-1907. In 1903 Dryden purchased the George Post estate which abutted his property. Following his death in 1911 the estate was owned by his son Forrest F. Dryden. From 1940-1996 'Stronghold' functioned as the Gill School but has since been returned to a private residence (as of 2005 it was owned by fashion designer Marc Ecko).
