In 1910, Pratt and his wife had a brick neo-Georgian mansion, known as "The Manor", designed by architect
Charles A. Platt built at their 55-acre
Glen Cove estate. In 1913, it was considered by Country Life Magazine to be one of the best twelve country houses in America. The home served as the summer White House for
Herbert Hoover. It is now the Glen Cove Mansion Hotel and Conference Center. The John Teele Pratt residence, at 11
East 61st St. in New York City was purchased by the Pratts, who hired
Charles Pierrepont Henry Gilbert to remodel the 1872 home in April 1907. In 1914, Pratt purchased the neighboring homes at 7 and 9 East 61st Street and hired Platt to tear them down and design a new residence. He is also the great-grandfather of actress
Suzanna Love (b. 1950). Through his daughter Phyllis, he was the grandfather of William A. Nitze of
Washington, DC, the chairman of Oceana Technologies and Clearpath Technologies, who married Ann Kendall Richards, an independent art dealer. Through his son
Edwin, he was the grandfather of singer-songwriter
Andy Pratt (b. 1947). == References ==
