Caleb Brewster Hackley, a leading supporter of the Unitarian movement, decided to give her summer mansion in Tarrytown, New York, for the purpose of creating a college preparatory boarding school for boys. The school would welcome students of diverse religious, economic, ethnic and national origin within an ethos shaped by the school's Latin motto, Iuncti Iuvamus, which we translate as, "United, W
e Help One Another." Mrs. Hackley funded the purchase of a beautiful estate not far from Hackley Hall, which provided the grounds for the Hackley School that we know today. Construction began, and the first new buildings were in use by 1902. Over the main entrance was engraved the phrase that has represented the Hackley spirit for over a century -- “Enter Here To Be And Find A Friend.”
