Henry T. Sloane House

The Henry T. Sloane House at nine East 72nd Street stands as a prime example of French Beaux-Arts architecture in the heart of the Upper East Side. Designed by the prestigious firm Carrère and Hastings, this limestone mansion was completed in 1896 for Henry T. Sloane, a wealthy heir to the famous W. & J. Sloane carpet and furnishing empire. At the time of its construction, the building was a symbol of the immense wealth of the Gilded Age, when elite families transformed this street into a corridor of opulent, competitive residential design. The history of the house is defined by a deep personal scandal that unfolded almost as soon as the doors opened. During the construction of the home, Henry T. Sloane and his wife, Jessie Ann Robbins, faced intense marital strife, fueled by rumors of her infidelity. By 1898, the couple had separated, and the grand mansion, intended to be a hub of social activity, became a place of bitter conflict. Sloane eventually moved out, and the house sat largely abandoned by the family, serving as a silent backdrop to one of the most talked-about divorces in New York society. Following the departure of the Sloane family, the residence attracted a succession of notable, and often reclusive, occupants. The publisher Joseph Pulitzer briefly leased the property before moving into his own palatial home nearby. In 1901, the banker James Stillman, president of the National City Bank, purchased the mansion and lived there until his death in 1918. Stillman was known for his cold and solitary lifestyle, often rattling around his massive properties with dozens of staff but very few visitors, earning him a reputation for profound detachment. The mansion eventually served a very different purpose in the mid-twentieth century when it became part of the Lycée Français de New York. In 1964, the school expanded its footprint into the building, using it as an educational space for decades. It was during this period, in 1977, that the structure was formally designated as a New York City landmark, ensuring the preservation of its historic limestone facade. In more recent years, the building entered a new chapter that secured its status as a piece of architectural history. In 2002, the government of Qatar purchased both this property and the neighboring building at seven East 72nd Street. A massive multi-year renovation project combined the two structures into a single, massive residence, creating what is considered the largest single-family home in New York City. This modern project included the addition of high-end amenities like an indoor swimming pool and roof terrace, all carefully integrated to respect the original Gilded Age design.
