Stepping into Astor's Manhattan mansion was like stepping into the Gilded Age: a gilded hall, a marble staircase, a dazzling ballroom, and lavish parties. However, that symbol of power vanished in just three decades, giving way to the modern metropolis.

For almost 30 years, a single woman decided who did and did not exist in fashionable New
York, and her word alone could lift a family into society or leave it permanently outside
the door.
When she at last built the grandest house of her life, a limestone chateau facing Central
Park, it was large enough to gather 1,200 dancers beneath a single roof.
Hi everyone, Ken here.

More on them later.
In 1830, Carolyn Webster Skimmerhorn was born at her family's home near Bowling Green in
Lower Manhattan, the ninth child of the shipping merchant Abraham Skimmerhorn and his wife
Helen Van Cortlandt-White.
The Skimmerhorns were among the oldest families in the city.
They descended from a Dutchman who had reached New Netherland in the 1630s, and for generations
they prospered as ship chandlers and ship owners trading between New York and Charleston.
This Knickerbocker lineage mattered enormously, and the social arithmetic of the day, descent
from the original Dutch settlers, outranked even the vast but far newer Astor fortune,
and it was the one thing money could never buy.
The young woman her family called Lena grew up understanding precisely where she stood
and how much that standing was worth.
In 1853, she married William Backhouse Astor, Jr., the middle grandson of John Jacob Astor
and heir to a portion of the largest fortune in the United States.
The first John Jacob Astor arrived in America after the Revolution, and built his wealth
first through a fur trading empire, then through the China trade, and finally, and most lucratively,
by buying enormous tracts of Manhattan real estate.
By his death in 1848, he was the richest man in the country.
His son, known in his own time as the landlord of New York, multiplied those holdings into
hundreds of buildings and rents that rolled in regardless of fashion or financial panic.
By marrying into this dynasty, Carolyn joined her unimpeachable old name to an almost limitless
supply of money.
For the first two decades of her marriage, Carolyn was occupied mainly with raising her
children, but the years after the Civil War handed her a mission.
A torrent of new money was pouring into New York, and the families who held it were hammering
at the gates of established society.
Carolyn appointed herself the guardian of the old order, and after the death of her
mother-in-law in 1872, she stood unrivaled as its leader.
Her chief lieutenant in this campaign was Samuel Ward McAllister, a Savannah-born lawyer
who had made himself the age's great authority on taste and protocol.
Together they built the machinery of exclusion.
McAllister organized the Patriarchs, a committee of 25 socially impeccable men who controlled
the most coveted subscription balls of the season, and he gave Carolyn the grandiose
nickname by which he loved to describe her, the Mystic Rose, borrowed from the figure
in Dante, around whom all of heaven turns.
It was Ward McAllister who gave the era its most famous phrase.
In 1888, he told a newspaper that there were only about 400 people in fashionable New York,
and that anyone outside that number would feel ill at ease in a ballroom and would make
others uneasy as well.
The figure was popularly tied to the capacity of Mrs. Nestor's ballroom, the implication
being that her annual party defined the absolute limit of polite society.
This chatty memoir of 1890 gave away too many of the old guard's secrets, and the woman
he had served for so long withdrew her favor.
When he died in 1895, Mrs. Nestor kept a dinner engagement rather than attend his funeral,
and the man who had crowned the Queen of New York was buried without her.
For most of her reign, Mrs. Nestor held court from a brownstone at 355th Avenue at the corner
of 34th Street, on the ground where the Empire State Building now stands.
She had enlarged that house with the ballroom that became the spiritual home of the 400,
but by the early 1890s, the tide of commerce was rising fast around her, and the construction
of her nephew's enormous hotel next door made the old neighborhood intolerable.
The fashionable world was already moving north toward the stretch of Upper 5th Avenue that
faced Central Park, and Carolyn resolved to follow it.
She owned a generous lot at the northeast corner of 5th Avenue and 65th Street, and
she entrusted her son Jack with the task of raising on it the most ambitious private
house the Avenue had yet seen.
The commission went to Richard Morris Hunt, the most honored American architect of the
age and the favorite designer of the Vanderbilt family.
Hunt conceived the building as a French Renaissance chateau in the manner of the early 16th century,
and he clad it entirely in pale limestone.
He had received the commission around 1893, and after roughly two years of construction,
the family took possession in early 1896.
The inaugural ball was held on the 3rd of February that year, when Carolyn's youngest
daughter led the cotillion in the vast new ballroom.
The interiors were carried out by the eminent Paris decorating house of Jules-Alain Defy,
and the white marble sculpture throughout was the work of Carl Bitter.
What Hunt produced was, in truth, two houses wearing the face of one.
From the street, the limestone front ran as a single colossal chateau, yet behind the
unified façade, a party wall divided the building into two mirror-image residences.
Carolyn occupied the northern half, addressed as 841 5th Avenue, while Jack and his family
took the larger southern corner, numbered 840, which enjoyed the extra light of windows
along 65th Street.
A single monumental gateway and carriage entrance served both households at once.
As we begin making our way inside, I want to just bring something to your attention.
A lot of videos have been created about Mrs. Astor's mansion over the last year by AI-driven
channels, which have hallucinated a lot of the details, or even claim that Mrs. Astor's
ballroom was actually in the Schwab mansion.
Some really outrageous stuff.
So if you've seen those videos, you might be surprised by what was actually inside,
recalled by myself, a real human architectural historian who has studied the original publications
and descriptions regarding the house for years.
Guests passed through great bronze gates into a vestibule crowned by a dome of glass, and
from there, into a hall lined with marble busts of the Astor forebears.
The corridor opened into a soaring marble-grade hall, out of which rose a broad cantilevered
staircase of white marble, its carved ornament the work of Carl Bitter.
It was down these stairs that Mrs. Astor, ablaze with diamonds, would make her descent
before a party, and it was on these same stairs, later in her life, that she suffered the fall
that hastened her final decline.
A reception room finished in the lighter and more delicate Adam style provided a setting
for greeting guests on formal occasions, a deliberate contrast to the heavier French
manner found elsewhere on the floor.
Its pale, fine-grained ornament gave the eye a moment of rest before the grander pleasures
that lay beyond.
The dining room was among the most theatrical spaces in the house.
Its carved walls were hung with tapestries depicting scenes of the hunt, while at the
end of the room, set behind Mrs. Astor's chair, stood a statue of Venus presiding over
the formal dinners.
The ballroom was the heart and glory of the house, and it doubled as the picture gallery
in which Mrs. Astor displayed one of the most celebrated private art collections in the
world.
It was the largest room in the mansion, stretching across the entire rear of the building and
rising through several stories to a stained-glass skylight carried on sculpture male figures.
The deep red satin-paneled walls held canvases by the most fashionable European painters
of the century, while across the marble floor lay four immense oriental carpets, a row of
long, narrow Persian runners in deep red, and scattered rugs woven from peacock feathers.
High on one wall, a musician's gallery was screened with Chinese panels so that the orchestra
could play on scene.
The single room could hold 1,200 people, three times the capacity of the famous ballroom
in our old house, and when both halves of the double mansion were thrown open on the
night of her January ball, it became for a few hours the undisputed center of high society.
Above the public floors lay the private world of the family, the bedrooms, the dressing
rooms, and a dome boudoir that no guest would ordinarily see, and higher still the quarters
of the servants who kept the whole great machine running.
The splendor on display below was, in the end, a staged set, built for the single purpose
of receiving the right people in the right way.
Mrs. Astor took a tragic fall down her finely polished marble staircase and was never quite
the same after, experiencing strokes and memory loss.
She passed away in the Fifth Avenue mansion in 1908, at the age of 78, and was laid to
rest in the Astor Vault at Trinity Church Cemetery.
Within a week of his mother's death, John Jacob Astor IV announced that he would take
the entire double house for himself, and he engaged the architectural firm of Crearin
Hastings, then at work on the New York Public Library, to fuse the two residences into one.
The reconstruction of the ground floor was nearly total and is said to have cost in the
neighborhood of half a million dollars, and the transformed mansion was ready by 1910.
The changes ran from the front door to the rear wall, and the principal rooms emerged
altered in both character and grandeur.

The wall that had divided the two houses came down, the twin staircases were torn out and
rebuilt against the rear of the building where they would be hidden away from view, and the
whole central space was reborn as a great reception court beneath a dome of glass.
The drawing room was kept much as Carolyn had known it, still rather heavy with gilding,
facing out onto Fifth Avenue.
It carried the older French spirit of the house forward into the new arrangement.
Shack's library was shifted to a new position within the reconfigured plan.
It remained a deliberately old-world room at the heart of a thoroughly modern reconstruction.
No space was more thoroughly remade than the dining room, where nearly the whole of one
wall was removed and replaced by an enormous bay window set in a grille of bronze.
Redesigned in a free Italian Renaissance manner and measuring roughly 40 feet by 30, it gleamed
with columns of rose-tinted marble, a checkerboard floor of black and white, tapestries in green
and gold, and a plaster ceiling worked in brown and gold.
The great ballroom, the one the two houses had always shared, was left essentially as
haunted built-in, a lofty rectangular hall lit from above and hung with the family's
French paintings.
Now, however, it belonged to a single residence, the crowning room of one of the largest private
houses in all of New York.
Astor presented the reborn mansion to society with a housewarming in March of 1910, and
for a brief season, the great rooms shone again as they had in his mother's day.
Shack's divorce in 1909 and his remarriage two years later to a woman nearly 30 years
his junior scandalized the very society his mother had ruled.
Returning from his honeymoon with his young and pregnant wife, he boarded the Titanic
and went down with a ship in April of 1912, the richest man on board.
The unified palace passed to Astor's eldest son, Vincent, who had little use for so vast
and costly a house and soon resolved to be rid of it.
The property was sold, its contents dispersed at auction, and around 1926, the great limestone
chateau was pulled down.
In its place rode Temple Emmanuel, the monumental Reformed synagogue completed at the end of
that decade, which stands on the corner of Fifth Avenue and 65th Streets to this day.
The double mansion at 845th Avenue stood for barely 30 years, yet in that short span, it
framed an entire age.
It was raised by an aging arbiter just as the rigid world she governed began to slip
from her grasp, joined into one by a son who would perish in the most famous disaster of
the century, and swept away within a single generation to make room for a house of prayer.
Dazzling, exclusive, and gone, almost as soon as it was finished.
And with that, I'll turn it over to you.
