One Lexington Avenue was completed in September 1911: twelve stories of brick and limestone by Herbert Lucas, who organized the cooperative as well as designing it. Its large apartments brought the scale of a private house above the trees of Gramercy Park.

Cyrus W. Field built his house here around 1852, with a matching home next door for his brother David Dudley Field. Cyrus hosted the March 1854 dining-room meetings that launched the transatlantic cable enterprise; David, principal author of the Field Code of civil procedure, had already begun to change how courts worked in New York and beyond.

Cyrus’s daughter, Isabella Field Judson, remembered forty years of family life at the corner, first numbered 84 and later 123 East 21st Street. In 1899, financier and railroad publisher Henry William Poor acquired both Field houses. Stanford White united them into a mansion at One Lexington Avenue, with Renaissance-inspired interiors and a glass conservatory facing the Park.

Poor’s banking firm failed in 1908, in the aftermath of the Panic of 1907. His books and furnishings went to auction; the property was sold in 1910 and cleared for Lucas’s cooperative. The apartment house occupies the ground of two adjoining family homes and a mansion that lasted barely a decade.

c. 1852–1899 · The Field houses

An ocean crossed, from a home on Gramercy Park

Two brothers, two kinds of reform

Cyrus had made his fortune in the paper trade. His house stood at No. 123 East 21st Street, earlier No. 84; David occupied the adjoining eastern house, No. 125, earlier No. 86. They lived side by side and were in daily contact.

David was the principal author of the Field Code of civil procedure, adopted in New York in 1848. It simplified pleading and brought actions at law and in equity into a common procedure. Other American states adopted versions of it, and English reformers studied the New York experiment. The eastern house belongs to the history of legal reform as surely as Cyrus’s dining room belongs to the cable story.

Four evenings at Field’s dining table

The first proposal was more modest. In 1854, the telegraph entrepreneur Frederick Gisborne approached Field about a connection between Newfoundland and the North American mainland. In his daughter’s account, Field sat in the library of his Gramercy Park home studying a globe and wondered why the line could not continue across the ocean to Ireland. He wrote to Samuel Morse about the electrical questions and to Matthew Fontaine Maury about the ocean.

Field then invited Peter Cooper, Moses Taylor, Marshall O. Roberts and Chandler White into his dining room. For four evenings, the five men sat around the table examining the earlier company’s records, studying maps and working through estimates. The agreement to take over Gisborne’s undertaking was signed on March 10, 1854.

Cooper had only a short walk from his own house at 9 Lexington Avenue, on the site of today’s No. 7. His grandson Edward Ringwood Hewitt would later live immediately east of the Field site, at 48 Gramercy Park North, or 127 East 21st Street. The cable’s backers and the Hewitt family belonged to the same few blocks.

Field’s globe survives. Made by Newton & Son in 1852, it is now in the Smithsonian’s National Museum of American History.

Dawn at David Dudley Field’s

The next founding meeting took place next door. On May 8, 1854, the associates gathered at David Dudley Field’s house at six in the morning. One of them had to leave town that day, so the business began before breakfast.

They formally organized the New York, Newfoundland and London Telegraph Company, chose Cooper as president and subscribed $1.5 million in capital. Henry M. Field’s account places the meeting in the first morning light: the plans discussed in one brother’s dining room had become a company in the other’s house.

The cable reaches across the Atlantic

The distance between those evenings on Gramercy Park and a working cable proved enormous. Field spent years raising money, negotiating with governments and bringing together the scientists, engineers and manufacturers the venture required. He crossed the Atlantic repeatedly, returning to the effort after each failure.

In August 1858, messages finally passed between Europe and North America. Queen Victoria and President James Buchanan exchanged congratulations; New York celebrated, and Tiffany sold souvenir sections of cable.

Within weeks, the signal failed. It took further setbacks and eight more years before the steamship Great Eastern laid a cable that established lasting service in July 1866. That September, the expedition recovered and completed the cable lost the previous year. Messages could now cross between continents without waiting for a ship.

The Fields celebrate fifty years

On December 2, 1890, guests gathered again at Field’s house. This time the occasion was his golden wedding anniversary with Mary Bryan Stone Field. What had begun as a gathering for close relatives grew into a large reception, and Cyrus’s brother, the Rev. Henry M. Field, conducted a renewal of their vows.

Greetings came from both sides of the Atlantic. An American commemorative certificate, now at the Smithsonian, carries more than two hundred signatures. William Ewart Gladstone, Oscar Wilde and Constance Wilde were among the signers of the separate British tribute.

After the Fields

Cyrus died in 1892; David Dudley Field died in his Gramercy Park house in April 1894. By the end of the decade, both houses had become boarding houses. Their large rooms had been subdivided, and much of what had filled them was gone.

A collector moves to the corner

The Field houses remained on Gramercy Park after the brothers’ deaths. In 1899, according to the building’s centennial history, Henry William Poor acquired them and joined them into a single residence at One Lexington Avenue. Poor was a banker and publisher of Poor’s Manual of Railroads, part of the business family whose name would become Standard & Poor’s. His passion for books, pictures and architectural objects would transform the familiar corner.

Between 1899 and 1901, Stanford White of McKim, Mead & White joined the two brownstones and remade their interiors. The architect had also made elaborate interiors for his own house across Lexington Avenue, on the site of the later Gramercy Park Hotel. His work at The Players, 16 Gramercy Park South, stood directly across the Park.

White made Poor’s home a setting for carved wood, marble, tapestries, paintings and antique furniture. A grand staircase rose through the main hall. Renaissance ceilings and woodwork enclosed a library of rare books and illuminated manuscripts; the collection was one of the house’s reasons for being.

Contemporary newspaper accounts, gathered by historian Tom Miller, put the April 1899 purchase at $200,000. Poor initially intended to demolish the houses. Instead, White’s remodeling removed the Park-facing stoops, added the Park-facing glass conservatory visible in the 1907 photograph and moved the entrance to Lexington Avenue. The old pair of addresses became One Lexington Avenue.

A ballroom on the Park

Once the remodeling was complete, the house filled with music. The Poors gave their first large entertainment there in December 1901. The following March, about 300 guests heard a sixty-piece orchestra conducted by Emil Paur, followed by supper and dancing.

Edith Poor’s wedding reception in January 1904 took place in the red-and-gold drawing room. These were rooms arranged for company as well as collecting: a private house capable of accommodating an orchestra and its audience.

Stately Homes in America, published in 1903, preserved seven views of the residence, including its conservatory, halls, dining room and drawing room.

An auction inside One Lexington

H. W. Poor & Co. failed in December 1908, in the aftermath of the Panic of 1907. From April 21 to 24, 1909, the American Art Association held an auction inside his house. The catalogue photographed the rooms and listed what buyers could take away.

The books had already begun to leave. Anderson Auction Company dispersed Poor’s library in five sales between November 1908 and April 1909. The furnishings sale followed the last of them.

Even the ceilings were for sale.

The catalogue described the main hall’s coffered ceiling as coming from an Umbrian palace, its painted panels filled with the gods of Olympus. In the drawing room, another ceiling told the story of Cupid and Psyche. Both ceilings were offered as numbered auction lots.

Doorways, mantels and light fixtures were offered too, with buyers responsible for taking down and removing the architectural fittings at their own risk and expense.

What the auction scattered

American Art News reported that the four-day sale brought $171,445. Mrs. Samuel Untermyer bought both of the painted ceilings: $2,000 for the main hall’s and $4,100 for the drawing room’s.

The Metropolitan Museum paid $7,100 for an Italian marble altar canopy, or ciborium, made around 1150 by Nicolaus Ranucius and his sons. The catalogue called it the Tabernacle of San Stefano in Fiano. It survives in the Met’s collection as object 09.92.3.

Architect Charles A. Platt bought tables, a fountain, a marble bench and four marble columns. Room by room, the fittings White had assembled passed into other hands.

The real estate followed the contents. Charles Buek bought the corner property from Mrs. Poor in January 1910; that spring it passed to the cooperative company Lucas organized. Poor’s stable on East 22nd Street also changed hands: the Record and Guide reported that Henry Sleeper Harper bought it from the Poor estate in 1911.

1910 to today · The cooperative

One address, many households

One Lexington becomes a shared home

The developer Charles Buek bought the house from Mrs. Henry W. Poor in January 1910, with an apartment building in mind. His first scheme, the centennial history says, called for forty-four apartments, a restaurant and a roof garden. Herbert Lucas, the architect he hired, reduced the number to twenty-four, mostly duplexes. The scheme accommodated large single-level apartments as well as homes arranged on two floors.

In May, Pease & Elliman resold the property for Buek to the Number One Lexington Avenue Co., organized by Lucas himself and capitalized at $250,000. The Real Estate Record and Guide described the new corporation and later explained that owners could help determine their apartments’ decoration and, within limits, their arrangement.

The builder Edward Corning and the lawyer John Brooks Leavitt were among this group of future owners; Leavitt became One Lexington’s first board president. Lucas already knew how to fit an apartment house into the neighborhood, having designed 24 Gramercy Park.

The early backers also included Rodman Gilder, Juliet K. Lamont, Cornelia B. Earle and the editor John S. Phillips. In June 1910, the general construction contract went to the Edward Corning Company. The contemporary estimate for the land and building together was $600,000.

The plans offered duplex and studio apartments, balconies looking over Gramercy Park, electric passenger and freight elevators, and a roof garden. The shared building would retain some of the space and individuality that families associated with a house of their own. High ceilings, open wood-burning fireplaces and rooms overlooking the Park trees carried familiar townhouse comforts into the shared building. Lucas’s double role as architect and organizer mattered: prospective owners could shape their rooms before moving in. The offer was house-sized living without sole responsibility for an entire house.

Excavation exposed soft ground. The centennial history records the lender’s insistence on digging farther down to bedrock and says part of an earlier house’s foundation was incorporated beneath the Park-facing wall. The booklet dates completion to September 1911, when owners and renters began moving in.

The twelve-story building changed the scale of the north side in September 1911. Three months later, Henry Sleeper Harper, at 131 East 21st Street, bought No. 133 next door “in order to protect his residence.” The report specifically noted the new cooperative at the corner. The later history of 45 Gramercy Park North includes the purchase and its unexpected sequel: in 1926, Harper hired Lucas himself to design his new home on East 38th Street.

Immediately east of One Lexington, the narrow mid-nineteenth-century house at 48 Gramercy Park North survived. At 127 East 21st Street, its few floors and iron verandas still meet the cooperative’s twelve-story wall. The change in scale is visible at a single lot line.

The rent would pay the maintenance

One Lexington’s founders intended to sell some apartments and rent out the others. The rent would pay the owners’ maintenance. That, at least, was the plan.

In practice, rental income did not cover everything: the centennial account records annual maintenance charges for the first buyers.

The architect’s oasis

In a 1917 essay, Lucas described Gramercy Park as an “oasis” in the city. Apartment houses had altered the skyline and brought more people, he wrote, yet the neighborhood retained its character. He saw cooperative ownership as a way to give residents a say in their surroundings and a home arranged to suit them.

An early apartment-house album preserved by the New York Public Library shows the two levels of Duplex Apartment B: principal living rooms downstairs, bedrooms above, and a private staircase connecting them.

The living room faces Gramercy Park, with two bedrooms occupying the same frontage upstairs. The dining room lies beside the living room; kitchens, pantries and service spaces sit farther back. The plan brings the rooms of a substantial private house together within two floors of a shared building.

The advertisement beneath the plans promises light on three sides, roomy apartments and open fireplaces. It also promises relief from a less glamorous problem: cooking odors. A special kitchen ventilation system was part of the offer.

Rooms for maids and a separate service elevator appear on the plan too. Live-in domestic staff were part of the household the designers had in mind. Prospective tenants could also request changes in decoration, within reasonable limits.

At home in early One Lexington

A photograph in the Museum of the City of New York’s collection takes us beyond the floor plans and into an apartment. Catalogued as Mr. Donald F. Crane. #1 Lexington Avenue and dated circa 1915–1930, it shows a hallway lined with bookcases, with a hanging lantern, patterned rugs and an arch framing the rooms beyond.

Books, framed pictures and small pieces of furniture make this passage part of the home’s living space. The view offers a glimpse of the individual interiors behind the apartment house’s shared façade.

A painter’s skylight and a writer’s papers

Henry Salem Hubbell, a painter trained in Chicago and Paris who had worked among the American artists at Giverny, needed a studio in his apartment.

The centennial booklet records Hubbell’s request to Lucas for a skylight and for the roof over his studio to be raised. The board’s answer will sound familiar: he could have the skylight, provided he paid for it.

He also obtained separate apartments on the two floors he owned so that one could be rented. Hubbell later painted presidents, including Franklin D. Roosevelt and Herbert Hoover.

Another early resident, Carolyn Frevert, came from the National Arts Club, where she had lived with her brother, the novelist and journalist David Graham Phillips. After his death in 1911, she managed his literary estate and the sale and publication of his writing.

The architect D. Everett Waid also lived here. His later work with Harvey Wiley Corbett included the Metropolitan Life North Building at 11 Madison Avenue, the massive structure north of the familiar clock tower. He later became president of the American Institute of Architects.

An editor’s daily walk

By 1923, John Huston Finley and his wife, Martha, had made their home at One Lexington: that year’s Knox College directory lists Martha Boyden Finley at the address. A former president of City College and New York State commissioner of education, Finley had joined The New York Times. His life here also included a quieter routine: a daily turn through Gramercy Park.

A TIME profile of May 3, 1937 describes another neighborhood undertaking. On behalf of neighborhood parents, Finley presented the Park’s gardener, Hannan, with a bronze medal and $1,000.

Laundry days and the question of awnings

The basement laundry ran on a timetable: the centennial history records allotted days for each family and a place for its ironing board. The cooperative idea reached all the way down to washday.

Before air-conditioning, residents asked permission to put up window awnings. The board allowed them on the north and east sides while keeping the Gramercy Park and Lexington Avenue fronts uncovered. The centennial booklet found no evidence that any were installed.

The entrance canopy was another addition to be agreed upon, receiving approval in December 1912. Upstairs, the kitchens were equipped with iceboxes before electric refrigerators became familiar. The building had been equipped for both gas and electricity.

Editors and a publisher

John S. Phillips was more than an early investor. Knox College’s 1923 directory lists the editor at One Lexington. A co-founder of McClure’s Magazine and later editor of The American Magazine, he belonged to the generation of editors who made investigative reporting a national force.

Mark Sullivan, then editing Collier’s, gave One Lexington as his home address in Harvard’s 1915 class report. A later generation of publishing is represented by William Warder Norton, co-founder of W. W. Norton & Company: the Century Association’s 1945 yearbook lists him here.

A studio and a short walk

Painter and illustrator Albert Sterner moved his studio from the National Arts Club to One Lexington. Ralph Flint’s 1927 biography found him still here, attached to Gramercy Park and unwilling to exchange it for the attractions of a European capital.

Architect Arnold W. Brunner had an equally local routine. A memorial published in 1926 recalls his daily appearance at The Players at five-thirty, just across the Park from his apartment. The neighborhood offered both a place to work and familiar company a short walk away.

The Rev. William Pierson Merrill, the longtime minister of Brick Presbyterian Church, is another resident recorded in the Century Association’s 1945 yearbook.

One Lexington in a winter scene

In February 1950, One Lexington appeared above a much busier foreground: children crossing the snowy paths, adults on the benches and the statue of Edwin Booth at the center of the Park. John Falter’s cover for The Saturday Evening Post sets the building at the upper right, its pale base and rows of windows rising behind the fence.

The bare branches open a view that summer foliage conceals. The familiar apartment house becomes part of a neighborhood scene, with most of the activity taking place below it.

The rental bargain wears thin

Empty apartments still needed care, repairs cost money, and rents did not reliably meet the building’s expenses. The centennial history follows the owners’ difficulties in keeping that original bargain going.

In 1954, according to the booklet, One Lexington began a reorganization away from corporation-owned rental apartments. Some rental arrangements continued afterward, so the transition was gradual.

The apartments themselves were never entirely fixed. A duplex might become two homes; separate floors might later be joined again. The centennial account records alterations as early as 1916.

What remains on this corner of Gramercy Park

The columned entrance, arched windows and limestone base give way to brick above, with decorative iron balconies and a projecting cornice. The long Lexington Avenue frontage and shorter Gramercy Park side appear together in the early apartment-house album. Seen across the garden, with the Edwin Booth statue in the foreground, the building is partly screened by trees.

Buek’s first announcement had promised buff brick and Indiana limestone. The building that emerged used red brick above its stone base, giving the corner the warmer color it has today.

The centennial history says Lucas retained the iron fence from Poor’s house and echoed its entrance in his design. Envoie Projects, which managed roof and facade work in 2023, records stabilization and repairs to that fence and attributes it to Stanford White. The 1909 auction catalogue separately lists a pair of Italian wrought-iron entrance gates as lot 123; the gates should not be confused with the surviving fence.

The boundary across the street

The corner looks like an anchor of the historic streetscape, but its city designation is a different matter. One Lexington Avenue stands outside the Gramercy Park Historic District designated in 1966, as do its neighbors to the east at 48, 45 and 44 Gramercy Park North. The 1988 extension did not bring this block into the city district.

One Lexington does lie within the larger Gramercy Park district listed on the National Register of Historic Places in 1980. The two districts have different boundaries; a National Register listing should not be mistaken for inclusion in the city’s landmark district.

A tablet on the corner

A bronze tablet recalls the house that stood here before the cooperative. The Gramercy Park Association unveiled it on June 20, 1929, with members of the Field family present. The surviving inscription begins its account of the site with “Here for forty years was his home” and commemorates the planning of the first transatlantic cable.
