The Man Who Built Florida Had His Wife Declared Insane: Whitehall, Palm Beach.
Palm Beach, Florida. 1901. Henry Morrison Flagler —
Standard Oil co-founder, the man who personally built
the entire east coast of Florida with his own railroad,
the man who transformed a mosquito-infested wilderness
into the most exclusive resort destination in America —
completed construction of Whitehall, a seventy-three
room Beaux-Arts marble palace that cost two and a half
million dollars to build and that contemporaries
immediately recognized as the most magnificent private
residence ever constructed in the American South.
Andrew Carnegie called it "the Taj Mahal of North
America." The New York Times covered its opening as
a national event. Flagler was seventy-one years old.
His new wife, Mary Lily Kenan, was thirty-four. The
woman who had been his wife for the previous nine
years — Ida Alice Flagler — was not present. She
was in a psychiatric institution in New York. Henry
Flagler had arranged for the state of Florida to pass
a law making incurable insanity grounds for divorce.
Ida Alice Flagler was then declared legally insane.
The divorce was granted. The palace was built.
But the full story of what happened to Ida Alice
Flagler — a woman who by multiple historical accounts
showed no signs of serious mental illness before her
marriage became inconvenient — has never been fully
established in any public accounting. The medical
records that would settle the question have never
been made fully available. The doctors who signed
the declarations were connected to Flagler's business
network. And the law that made it all possible —
a law passed by the Florida legislature specifically
to enable this single divorce — was repealed shortly
afterward, as if the state itself recognized what
it had done.
Today, Whitehall operates as the Flagler Museum in
Palm Beach and receives hundreds of thousands of
visitors annually who tour the marble halls and
the grand ballroom and the rooms filled with the
accumulated luxury of America's Gilded Age. The
official tour does not dwell on Ida Alice Flagler.
The palace that was built on her destruction is
immaculate. The questions about what was done to
her remain exactly where Henry Flagler left them —
unanswered, and deliberately so.
A full history documentary about Whitehall, Palm
Beach — from Henry Flagler's creation of modern
Florida to the palace built on America's most
disturbing Gilded Age secret.
