Speaker 1 (00:04):
Welcome to Aaron Benky's Cabinet of Curiosities, a production of
I Heart Radio and Grim and Mild. Our world is
full of the unexplainable, and if history is an open book,
all of these amazing tales are right there on display,
just waiting for us to explore. Welcome to the Cabinet
(00:27):
of Curiosities. Giovanni Casselli wanted nothing more than to talk
to people. His only problem is that the people he
wanted to talk to lived very far away. Perhaps that
was why he became a Catholic priest, so he could
(00:48):
have a direct line to someone else very far away.
Born in Seattle, Italy, in eighteen fifteen, Casselli may have
arrived a few hundred years too late for the Renaissance,
but he certainly grew into quite the Renaissance man. In
addition to getting ordained in eighteen thirties six, he also
studied history, science and literature. Casselli eventually transitioned from being
(01:09):
a student to being a teacher. He tutored Italian aristocrats
in Parma for several years before his exile to Florence
for political activism. He soon took a job as a
physics professor at the university. There, Casselli soon became entranced
by the sciences. His own teacher, Leopoldo Nobili, taught him
about subjects like electro magnetism and electro chemistry. Casselli took
(01:32):
it upon himself to adapt those lessons into a journal
he called The Recreation, which was meant to distell such
complicated science into a more accessible form. One particular topic
struck Casselli during his tenure at the university, electricity, specifically
its use in transmitting signals from one place to another.
(01:52):
When he wasn't teaching, Casselli was researching how to send
messages across long distances over wire. Now, the telegram, which
sends electrical pulses across a vast network of wires, had
existed since the eighteen forties. Casselli didn't want to send
beeps and blips, though, he wanted to send words and
even pictures. Unfortunately, he was limited by the technology at
(02:14):
the time. Sending messages from one location to another required
a lot of power and a method of synchronization between
the transmitter and the receiver. After many years, though, he
finally cracked it in the eighteen fifties with his invention
he called the pan telegraph. It was six ft tall,
shaped like a giant wishbone, and was powered by massive batteries.
(02:37):
On one side, two curved metal plates were situated next
to each other, a transmission plate and a receiving plate.
The transmission plate held the message to be sent, which
was written in a non conductive ink. To send it,
a stylist would travel across the plates in parallel lines
until the message had been scanned. The information gathered from
(02:58):
the conductive plate and the non conduct if inc was
then sent over telegraph lines to another Pan telegraph set
up elsewhere. A pen fixed over the receiver plates on
that device would write or draw the incoming transmission on
a new piece of paper. To solve his syncretization problem,
Casselli used a fairly low tech solution, a pendulum clock
(03:19):
known as a regulating clock. The pendulum would swing back
and forth, completing and breaking the circuits over and over again,
keeping both the transmitter and receiver in sync. He first
demonstrated his device in eighteen fifty six to Leopold, the
second Grand Duke of Tuscany. The Duke was in awe
of what Casselli had accomplished. And provided funding for his
(03:40):
other experiments and inventions for some time. Eventually, though, the
Duke grew bored waiting for the next big thing from
the physicist. Seeing the writing on the wall, Caselli packed
up and headed to Paris, where he showed off his
pan telegraph to Napoleon the Third, and like the Duke,
Napoleon was hooked. Casselli conducted a test of his device
between Paris and Amia, a distance of almost ninety miles.
(04:03):
The machine passed without a single hiccup. Another message was
set nearly five hundred miles from Paris to Marseilles. Napoleon
was convinced. In eighteen sixty four, the pen telegraph became
an official and legally authorized method of transmitting written messages
across long distances. It didn't last long though. While impressive
and relatively fast, the device was not the most reliable
(04:25):
method of sending information from one place to another. Eventually,
Casselli walked away from it entirely and went back to
Italy to live out in the rest of his days.
Eleven years later, an inventor named Alexander Graham Bell would
receive the patent for a little device known as the telephone.
It goes without saying that the telephone changed the way
people communicated all over the world. But it was Giovanni
(04:48):
Casselli who went down in history is the man who
gave us something even more impressive, the very first facts machine.
(05:09):
Wilmur McLean wasn't just as simple farmer. He had moved
with his wife to her plantation near Manassas, Virginia, a
home they called Yorkshire. Unsurprisingly, McLean was an outspoken supporter
of the Confederacy, like most of his Virginia neighbors. That
was probably why Confederate Brigadier General P. G. T. Beauregard
had chosen McLean's farm to be his base of action.
(05:32):
Signs of a major conflict had been evident for months,
as more and more states seceded from the Union. Following
the capture of Fort Sumter by South Carolina troops back
in April, Abraham Lincoln enlisted tens of thousands of volunteer
soldiers to prepare for war. Wilmer fled his home with
his family on July seventeenth, eighteen sixty one. Beauregard had
(05:53):
arrived that day with his staff to commandeer the land,
the house, and the barn as his headquarters. Thirty five
thousand Union troops had marched for two days in the
blistering summer heat, finally arriving at bull Run, while roughly
thirty two thousand Confederate soldiers had taken over Manassas Junction
and the surrounding areas. On the evening of July eighth,
(06:15):
Beauregard was sitting in Wilmur's home waiting for his dinner,
when out of nowhere, a visitor came tearing through the
front door and landed in the fireplace. It was a cannonball.
Dinner may have been canceled, but the Battle of bull Run,
and in a way, the Civil War itself, had officially begun.
For four years, brother fought brother, father fought son. When
(06:36):
the fighting had finally stopped, seven hundred and fifty thousand
souls had been lost, about two point five percent of
the country's population, and almost half of the bodies were
never identified. Wilmer had been too old for the front lines. However,
he did find ways to support the South. He made
money as a sugar broker and smuggler, bringing it to
(06:57):
the Confederate Army through Union black aides. A year after
Beauregard had taken control of his home and turned his
barn into a field hospital. Wilmer came back to the
plantation to help out in other ways. The house had
seemed quite a bit in his absence. As you might imagine,
the wood had splintered where cannon fire and bullets had
gone through its walls. It was no longer the place
(07:18):
where he and his wife had hoped to raise their family.
It had become a war torn shell of its former self.
Even so, this had been his home, and Wilmur chose
to stay for the winter as a quartermaster to support
the troops. When the snow started to melt and budding
flowers blossomed, the fighting between the North and the South
grew more heated as well. Wilmer decided that he'd had enough.
(07:40):
He and his family traveled over a hundred miles away
to another tiny village in Virginia, far from the blood
stained fields and air choked with gunpowder. He used his
money to buy a new house, a converted tavern that
had been built in eighteen forty eight by a man
named Charles Rain. Rain's family sold it to Wilmer in
eighteen sixty three, and the one time farmer breathed a
(08:01):
sigh of relief, believing that he had left the violence
of war of his previous home in the past. Unfortunately,
he would not be so lucky. On April nine of
eighteen sixty five, Wilmer was greeted on the street by
Charles Marshall, a Confederate colonel who randomly stopped the first
man he saw to ask a simple question. Was there
a home nearby where General Ulysses S. Grant of the
(08:22):
Union Army could meet peacefully with Confederate commander General Robert E. Lee.
Wilmer took Marshall on a tour of an old brick
house he thought might work, but Marshall told him no,
it had to be nicer, somewhere quiet and respectable, where
the two men could sit down and talk things out.
Wilmer hesitated before eventually suggesting his own home as a
(08:44):
possible meeting place right there in the village of Appomattox
Courthouse and Marshall accepted. Lee and Grant sat across from
each other in Wilmer's lavish parlor as the Confederate general
through in the town. The war was over and the
South had lost the Union officers and attendance, hooted and hollered,
getting downright rampunctious as they tore the house up, looking
(09:07):
for any and all souvenirs to mark the momentous occasion.
They cut strips of fabric out of Wilmer's furniture. They
took silverware and candlesticks, and even a doll belonging to
his young daughter. They paid for the damage with money
they practically forced into the man's pockets before leaving with
their keepsakes, and Wilmur McLean became the only man in
(09:29):
history with the right to say that the Civil War
had started in his backyard and ended in his front parlor.
