In the 1870s, the blocks branching off from Fifth Avenue in the 80s saw the construction of high-stooped brownstones. At the turn of the century, however, those ubiquitous chocolate-colored homes were out of fashion. They were quickly being replaced or drastically remodeled as lavish, American basement mansions.
On October 5, 1901, the Real Estate Record & Builders' Guide reported, “Mr. F. De R. Wissmann, believing that there is a demand for high-class English basement dwellings, has undertaken the erection of two of the finest type, at Nos. 9 and 11 East 84th st, almost adjoining the residence of the late J. Hooker Hamersley.” The article added, “Warren & Wetmore, the well-known architects, have been entrusted with the duty of designing these houses, and the result will undoubtedly appeal to that class of people who appreciate well-planned residences suitable for entertaining.”
Construction of the limestone faced mansions was completed in 1903 at a cost of $210,000--about $4 million each. Fraternal twins, No. 9 was slightly less showy than No. 11, which boasted a two-story bay upheld by a sumptuous cartouche. The midsection of No. 9, in contrast, featured grouped windows, those of the second floor, or piano nobile, fronted by an iron-railed stone balcony.
A second balcony sat atop the limestone cornice above the third floor. The fifth floor took the form of a mansard, pierced with round, copper-clad French dormers.
Finding an owner for the opulent palace was apparently tricky for Wissmann. It was not until December 30, 1906 that the New York Herald reported that he had sold 9 East 84th Street to Mary Cunningham Bishop and her brother, Ogden Mills Bishop.
Born in 1864 and 1878, respectively, they were two of the eight children of the Heber Reginald Bishop and Mary Cunningham. Heber Bishop died in 1902 leaving an estate equal to $116 million in 2026 terms.
Neither Mary nor Ogden would marry. The siblings moved through society nearly as a couple, traveling, entertaining, and spending their summers together.
On October 15, 1911, the New-York Tribune remarked, "Ogden Mills Bishop and Miss Mary Bishop will spend the winter abroad. Their house, No. 9 East 84th street, will be occupied for the season by Ogden Livingston Mills and his bride, who was Miss Margaret Rutherford."
Ogden Livingston Mills was a second cousin of the Bishops through the Cunningham family. He was born on August 23, 1884 to the socially prominent Ogden Mills and his wife, the former Ruth T. Livingston. He and Margaret Rutherford were newlyweds, married a month before the New-York Tribune's article. Margaret had a pedigree equal to that of her husband. The daughter of Lewis Morris Rutherfurd Jr. and Anne Harriman Rutherfurd, she was the step-daughter of William Kissam Vanderbilt and the granddaughter of Lewis Morris Rutherfurd and Oliver Harriman.
The couple quickly entered the social swirl. In reporting on "the first big assemblage of fashionable New Yorkers" at the opening of the 1911-12 Metropolitan Opera season, the New York Herald remarked on October 29, "Mr. and Mrs. Ogden Livingston Mills, who are now at Roslyn, L. I. and will soon be at 9 East Eighth-fourth street, will probably be in the box of Mrs. Mills's stepfather, William K. Vanderbilt."
As it turned out, the Millses' stay at 9 East 84th Street would extend well past that winter social season. In fact, Mary and Ogden Bishop established their permanent residency in Paris.
Ogden L. Mills was highly involved in the Republican Party. On December 16, 1913, for instance, the New-York Tribune reported, "Ogden L. Mills, treasurer of the Republican County Committee, recently made a tour of the state to determine just what sentiment there was for a progressive organization of the Assembly." The article noted, "On Friday night, he had several of the local leaders and a dozen or more of the upstate progressive leaders at a dinner conference at his home, No. 9 East 84th street." Mills would be a delegate to the 1912, 1916 and 1920 National Conventions.
The Mills country estate (today a state park) with its sprawling neo-Classical mansion was in Staatsburgh, New York. from the collection of the Library of Congress.
The population of 9 East 84th Street was somewhat unexpectedly increased in 1914. George Winthrop Sands and his wife, Tayo Newton Sands, had two children, George Jr. and Anne Barbara. George Sr. was the step-son of William K. Vanderbilt (the son of Anne Harriman Vanderbilt from her first marriage) and the half-brother of Margaret Rutherfurd Mills. George Sands died in an automobile accident in France on July 29, 1908. George Jr. and Anne were orphaned on August 23, 1914 when their mother died of tuberculosis at the age of 26 in Anne Harriman Vanderbilt's French home, the Château St. Louis de Poissy.
Ogden and Margaret were made guardians of George and Anne, who were six and eight years old, respectively. Along with the children came their governess. In reporting on Tayo Sands's will on December 22, 1914, The New York Times said, "There is a bequest of $5,000 to Andree Pitiot, governess of the two Sands children, at 9 East Eighty-fourth Street."
The family remained at least through 1915, the year Ogden Livingston Mills was elected to the New York State Senate. In the meantime, the title to 9 East 84th Street had been transferred to Francis Cunningham Bishop, a sister of Ogden and Mary Bishop.
In 1918, Francis leased the mansion to Prentiss L. Coonley, director of the Gas Defence Plant on Long Island City. Francis briefly lived here before selling the property in August 1920. The Real Estate Record & Guide reported that the buyer was "a prominent resident of a city in the Middle West, who is coming to New York to live."
Moving day, October 5, 1920, was fraught with drama. The Evening World reported, "Miss Bishop was moving yesterday and left her handbag with the money in it on a table." Later that afternoon, Francis opened her bag and discovered the money, a total of $21, was missing. Police went to the moving company's office. Under heavy interrogation, the van driver confessed. He took off his shoe and pulled out the cash. (It would translate to about $335 today.)
The prominent Middle Westerners mentioned by the Record & Guide were railroad mogul George Theron Slade and his wife, the former Charlotte Hill. Charlotte was the daughter of James J. Hill, president of the Great Northern Railroad. The couple was married in 1901 in Hill mansion in Minnesota. They had two children, George Norman, born in 1902, and Georgiana Mary, born the following year.
By the time the Slades purchased 9 East 84th Street, George was a vice president of the Northern Pacific Railroad, president of the Tide Water Oil Sales Corporation, and a director of the Lehigh Valley and the Southern Railway. The family maintained a residence in St. Paul, Minnesota.
Tragically, just three years after moving into the mansion, Charlotte Hill Slade died "after a long illness," according to The New York Times on December 14, 1923. She was 48 years old.
Charlotte had been independently wealthy. She left an estate equal to more than $28 million today. After certain charitable bequests, she left her real estate to George and the rest to the children. George and Georgiana would have a long wait to receive their inheritances. The will said, "when the son and daughter attain the age of 30 years each is to receive $300,000 out of the trust and on attaining 40 years of age all of the principal."
George took over the responsibilities of organizing his daughter's debut and her engagement. He announced Georgiana's engagement to Charles L. Peet on October 24, 1929. The ceremony took place in the 84th Street mansion on December 30 that year.
George T. Slade died in the St. Paul residence on January 24, 1941. While the bulk of his estate was divided between Georgiana and George, he left 3,000 acres of land in North Dakota as "an inviolate sanctuary for migrating birds." Georgiana inherited 9 East 84th Street and its furnishings.
Georgiana and Charles Peet lived in St. Paul and were, apparently, not interested in retaining possession of the Manhattan townhouse. On June 11, 1941, The New York Times reported that Georgiana had sold the mansion to "a former resident of Rome, Italy." That buyer was Count Cecil Pecci-Blunt.
He was born in Brooklyn as Cecil Blumenthal, the son of a wealthy merchant. Following his father's death, Cecil's mother moved to Paris and changed their surname from Blumenthal to Blunt. There she married Duke de Montmorency. Cecil grew up in what was termed "the Continental circuit." He married Mimi Pecci, a member of an aristocratic European family. She was the niece of Pope Leo XII, who conferred Cecil a Papal title of count. Following the marriage, Cecil reinvented his surname, merging his wife's and part of his own. The couple had five children.
In addition to the 84th Street townhouse, the Pecci-Blunts maintained a "handsome house in Montecito, a ranch of many acres in Arizona, an imposing residence in Paris, an ancient palazzo in Rome and Villa Reale, a country retreat at Marlia in the Tuscan hills," according to the San Francisco Chronicle.
Ten years later, on December 3, 1951, The New York Times reported that Bee-Lee Holdings, Inc., had purchased "the former residence of Cecil Pecci-Blunt." The article said, "The new owners plan to convert it to small apartments from plans by Alexander Zamschnick, architect."
The renovation resulted in doctor's offices on the first floor and two apartments each in the upper portion. On September 18, 1992, The New York Times reported, "Marc de Montebello, the 27-year-old son of the Metropolitan Museum of Art's director, Philippe de Montebello, is opening a private art gallery at 9 East 84th Street." The gallery, according to the article, would specialize in 19th and early 20th century paintings and drawings. The Montebello gallery would be joined in the building by Victoria Munroe Fine Art the following year.
In 2017 a fire that tore through 7 East 84th Street spread into No. 9. The restoration resulted in 9 East 84th Street's being returned to a single-family home. It was sold by real estate investor and venture capitalist Carl Berg and his wife, Rachel, in 2019 for $19 million. In reporting the sale, The New York Times remarked that it had "seven bedrooms, six full baths and four powder rooms. Its amenities include a basketball court and a 53-foot pool with a separate hot tub."
