Built in 1835, it is one of the city's best-preserved examples of Greek Revival architecture, and was home to a prominent businessman and educator.
A two-story ell was added onto the north (rear) end of the house, and modified in 1938 to accommodate a garage in its basement area.
The interior retains original features, including wide flooring, Greek Revival fireplace surrounds, and door and window hardware.
