Henry William Poor House, 1899-1901. Formerly known the Cyrus W. Field mansion, this turn of the century photo depicts 1 Lexington Avenue after renovations by the architect Stanford White (a fellow Gramercy Park resident) on behalf of its new owner, the banker Henry William Poor. Poor purchased adjacent townhouses, both previously in the Field family, in April 1899, with the intention of building a larger and more modern mansion on their site. Apparently, White was able to convince Poor to abandon his tear-down project. Instead, the architect led a comprehensive interior renovation in characteristically opulent style. Outdoors, the building’s entrance was shifted to Lexington Avenue, in order to accommodate a windowed conservatory facing the park. Poor, for whom Standard & Poor’s is named, was forced to sell the mansion and its furnishings after the 1908 failure of certain investments and the subsequent liquidation of his assets. The house was razed in 1910 to be replaced by a 12-story apartment building.
