INVESTIGATE

In the summer of 1842, ten thousand pamphlets flooded New York City showing a beautiful mermaid from the South Pacific. A British scientist had brought it all the way from London. Crowds rushed to see it.

What they found was a shrivelled, three-foot creature with a monkey's screaming face and a fish tail. It was hideous. And it was the work of P. T. Barnum — the greatest showman who ever lived.

The mermaid was fake. The scientist was an actor. The newspaper stories were planted. And Barnum's profits more than doubled.

The Hoax

1842

P. T. Barnum leased a fake mermaid from Moses Kimball for $12.50 a week, invented a fake scientist named "Dr J. Griffin," planted stories in newspapers, and distributed 10,000 pamphlets showing a beautiful mermaid. The real specimen was a monkey sewn to a fish.

Cost to Captain Edes

$6,000

About $150,000 today. Edes used stolen ship funds and never made a penny back.

Pamphlets

10,000

Distributed across New York City — every one showing a beautiful mermaid.

Specimen Size

3 feet

Smaller than a five-year-old child. Barnum called it "ugly" and "diminutive."

The Evidence

THE SPECIMEN

The Feejee Mermaid

A three-foot dried specimen: the upper body of a young monkey stitched to the tail of a large fish. X-rays revealed wire, nails, papier-mache, and bones from multiple animals inside. Made by Japanese fishermen around 1810.

THE PAMPHLETS

The Beautiful Lie

Barnum distributed 10,000 pamphlets showing a gorgeous, graceful mermaid — nothing like the shrivelled specimen. By the time visitors saw the real thing, they had already been convinced it was genuine.

THE FAKE SCIENTIST

"Dr J. Griffin"

Barnum's associate Levi Lyman posed as a British scientist, gave lectures, and declared the mermaid genuine. He was not a scientist. He was not British. The "British Lyceum of Natural History" did not exist.

How the Hoax Unfolded

~1810

The Creation

Japanese fishermen create a ningyo — a fake mermaid made by sewing a monkey's upper body to a fish tail. It is one of many such objects made as traditional craft pieces.

1822

The Purchase

Captain Samuel Barrett Edes sees the mermaid in Batavia (Jakarta) and buys it for $6,000 using money from his ship's expense account. His employers sue him. He dies in poverty.

1842

The Showman

Edes' son sells the mermaid to Moses Kimball, who leases it to P. T. Barnum for $12.50 a week. Barnum begins his marketing campaign.

JUL 1842

"Dr Griffin" Arrives

Levi Lyman checks into a New York hotel as "Dr J. Griffin," a British scientist. Barnum distributes 10,000 pamphlets. The mermaid goes on display at Concert Hall on Broadway.

AUG 1842

The Exhibition

The mermaid moves to Barnum's American Museum. Attendance triples. Profits more than double. Scientists argue. The public pours in. Barnum watches the money roll in.

JUL 1865

The Fire

Barnum's American Museum burns to the ground. Whether the mermaid was inside remains a mystery. It may have already been returned to Kimball in Boston.

The People in This Story

The Showman

P. T. Barnum

America's most famous showman. He invented a fake scientist, planted newspaper stories, printed misleading pamphlets, and turned an ugly dried specimen into the sensation of 1842.

The Captain

Samuel Barrett Edes

A sea captain who spent $6,000 of his employer's money to buy the mermaid in Batavia. He believed it was real. He tried to exhibit it in London, failed, and never made the fortune he dreamed of.

The Actor

Levi Lyman

Barnum's associate who posed as "Dr J. Griffin," a distinguished British scientist. He gave lectures, spoke to reporters, and convinced the public the mermaid was genuine.

The Question That Remains

Barnum never claimed the mermaid was real himself. He hired an actor to say it. He let the newspapers draw their own conclusions. He showed people an ugly specimen and let them believe what they wanted.

Was Barnum a dishonest con artist — or an entertainer who gave people exactly the excitement they were looking for?
