This house was built by George W. Denton in 1875. It is not shown on the Beers-Comstock Map, which was published in 1873. However, its site was surveyed by Singleton Mitchell on 8/15/1874 and it may be assumed that construction started shortly thereafter. The Mitchell survey indicates that the site included 2.11 acres, a bit more than it does today. However, the site, at that time, extended to the middle of West Shore Road. It is one of four Roslyn "showplaces" mentioned in "Long Island & Where to Go," a guide-book published by the Long Island Rail Road in 1877. All four houses (Bogart, Bryant, Denton and Eastman) survive. The Denton House is described as standing on "elevated ground above the bay, and across the water we see the residence of William Cullen Bryant.
