Some unknown history questions are here and it is very basic question I can I can put on here.:-
1. What happened to Einstein’s brain?


Before his death in 1955, Albert Einstein had
requested that he be cremated, so his corpse didn’t
become the plaything of superfans and scientists.
Yet the on-duty pathologist, homas Harvey, removed
Einstein’s brain during the eminent physicist's autopsy.
Many were outraged, but Harvey convinced Einstein’s
son to let him keep the brain, promising that it would
further the cause of neuroscience. Indeed, he sliced
the brain into over 200 pieces, some of which he sent
to medical experts in the hope they could find clues to
Einstein’s brilliance.
However, few were interested in this madcap scheme,
so Harvey kept most of the brain, in two jars, inside a beer
cooler. Eventually, he tried to pass the bits of brain on to
Einstein’s granddaughter, but she didn’t want them either.
It wasn’t until 1978, when a journalist reported
Harvey’s bizarre quest, that scientists took an interest.
But Harvey’s DIY approach to preservation likely means
any experimental results are flawed. he brain slices are
now kept in two American medical museums.

2. Who invented
the umbrella?


he use of umbrella-like
devices to provide shelter
from the sun is an ancient
one. Carvings from the Assyrian
Empire depict parasols of circular
fabric mounted on a stick as early
as 1300 BC, and they appeared in
China around the time of Christ. It
is thought that the folding parasol,
for ease of carrying, was invented in
China 1270.
Although first appearing centuries
earlier, parasols did not become
popular in Europe until the late 16th
or early 17th centuries, probably by
way of visiting Persian merchants
and diplomats. he word ‘umbrella’
was coined in Italy around 1610
to describe a particular parasol of
expensive silk, decorated with gold or
silver thread.
By this time, the desire for
umbrellas protecting people from
the rain as well as the sun was
growing. In 1637, King Louis XIII
of France bought the first
waterproof umbrella, although
sadly the name of its maker
was not recorded. His umbrella
had a canopy of heavy silk and
was liberally soaked in thick
oil to protect the monarch
from Parisian downpours.
By the time the
collapsible umbrella with a
folding stick was developed
by Marius de Paris in
1715, the umbrella had
become a fashion item for
ladies only. Englishmen
stoically wore hats until
the 19th century.

3. How many horses

died in World War I?


he success of the Steven
Spielberg's 2011 film War Horse
threw the spotlight on the role
horses played in the war. As the film
suggests, they suffered horribly –
perhaps as many as eight million died.
At the start of the war, the cavalry was
a cornerstone of the British Army, with
horse-mounted units among the first to
go into action against the Germans. But,
as trenches, tanks and mounted machine
guns came to dominate the Western
Front, cavalry units increasingly found
themselves banished to the sidelines.
Despite this, horses remained essential
to both sides’ war efforts – especially
in transporting materials to the front.
And the cavalry was still capable of
making waves away from the Western
Front – most notably in Palestine, where
they played a starring role in the Allied

victory over Turkish forces.

4. WHEN DID WINSTON
CHURCHILL FIRST
USE HIS
FAMOUS
V-SIGN?



Initially suggested
as a defiant
symbol by the
Belgian politician Victor
de Laveleye, the BBC
adopted it for their ‘V for
Victory’ campaign that
spread across Europe in
early 1941. Churchill first
used the gesture during a
speech that July, subsequently
being photographed with two
fingers in the air at every given
opportunity. “The V sign is the
symbol of the unconquerable
will of the occupied
territories,”
he declared, “and a
portent of the
fate awaiting

Nazi tyranny”.

5.Who invented the

toothbrush?




he history of oral hygiene
goes back a long way, with
recent archaeological finds
proving that there were even Stone
Age dentists. But who invented the
toothbrush? It depends on your
definition. To freshen their breath,
the people of ancient India
chewed an aromatic twig, called
a dentakashta, and the Egyptians,
Babylonians, Romans and Tudors
all did something similar. But it
seems the first people to actually
make a toothbrush were the
medieval Chinese who, in the
1400s, stitched spiky pig bristles
into a bamboo or bone handle.
hese were brought back to
Europe by travelling merchants;
French physicians briefly used
them, but they didn’t catch on in
Britain. So while the Chinese can
technically take all the credit, the
person commonly dubbed the
‘inventor’ of the toothbrush is an
18th-century Brit.
William Addis was a
professional rag-dealer in the
East End of London. In 1780, he
was chucked in Newgate Prison
– perhaps for rioting – and it was
here that inspiration struck.
he story goes that Addis
whittled holes into a pig bone
left over from his dinner and
threaded them with bristles
from a nearby broom, thereby
creating his toothbrush prototype.
When he was released from jail,
he experimented with other
materials and soon started selling
toothbrushes. He enjoyed great
success, as the sugar-obsessed
population of Georgian Britain

suffered appalling tooth decay.
