1. The Franklin Stove was
revolutionary
In 1740, Benjamin
Franklin invented his now-famous Franklin Stove. This freestanding stove
produced more heat for less fuel compared to contemporaries of the period.
The stove was
actually a specially designed fireplace that had a hollow baffle near the rear
to transfer more heat from the fire to the room's air. Hot fumes and
smoke from the fire were drawn over an "inverted siphon" to achieve
this effect and help produce less smoke than ordinary fireplaces.
Smoke and other
exhaust gases were then channeled up the chimney. Unfortunately for Franklin,
it wasn't a massive commercial success until it was later improved by David
Rittenhouse.
2. Franklin also invented a new
musical instrument
Benjamin Franklin
also turned his hand to creating new forms of musical instruments. Chief
amongst them was his interesting glass instrument called the Armonica.
The Armonica was invented in around 1761 and its
name derives from the Italian word "Armonia" meaning harmony.
You are probably familiar with so-called "glass
harps" or "musical glasses" whereby players rub their fingers
around the rims of water-filled wine glasses. The Armonica is, in essence, and
descendant of this ancient technique.
Franklin's Armonica, used a series of glass bowls,
or goblets, of graduated size that produced musical tones through friction. It
was played by rotating the glasses around a central shaft.
Both Ludwig van Beethoven and Wolfgang Amadeus
Mozart composed music for the strange instrument. Today, similar devices are
known more commonly as friction idiophones.
3. Benjamin Franklin actually
invented bifocals
Benjamin Franklin is
commonly credited with the invention of bifocal glasses. Whilst there is
some debate about whether this is true, there is strong evidence to show that
this is indeed true.
It may be the case
that bifocals are yet another example of an invention that is independently
developed by multiple people over time. Whatever the case, like all great
inventions, they were the product of the inventor's own frustration with
something in the world.
In this case, Benjamin Franklin has become so tired
of his own aging eyes that he decided to do something about it. Through trial
and error, he finally managed to produce a pair of glasses that allowed him to
see close-up and far away without the need to change his glasses.
4. He helped pen the American
Declaration of Independence and the U.S. Constitution
Probably his most
important accomplishment was being one of the authors of the American
Declaration of Independence. In 1776 he was appointed as a member of the
Committee of Five that would go on to draft the Declaration.
Franklin, then of advanced age, was temporarily
disabled by gout and unable to attend most meetings of the Committee, Franklin
made several "small but important" changes to the draft sent to him
by Thomas Jefferson.
At the signing, he is quoted as having replied to a
comment by John Hancock that they must all hang together: "Yes, we must,
indeed, all hang together, or most assuredly we shall all hang
separately."
Franklin was a very strong advocate for the right to
free speech and, in 1787, also signed one of the most important documents of
all time. The United States Constitution.
To this day, it remains one of the bastions of legal
protection for individual liberty in the world.
5. He was the first Postmaster
General of the United States
In 1737, Benjamin Franklin was
appointed as the very first Postmaster for Philadelphia by the British Crown
Post. A post he held until 1753.
Franklin threw
himself into the task and implemented many effective measures that enabled his
post office to become the first profitable one in any British colony of the
time.
In 1775, when the Second Continental Congress
established the United States Post Office, Franklin was made its postmaster
general due to his experience in the field.
Franklin's postal service still exists, more or
less, today but was renamed the United States Postal Service in the early
1970s.
6. He helped create the First
American Political Cartoon
The freedom to openly criticize
politicians and other powerful figures in society is critical to freedom
of thought and speech. Whilst an announcement to those who hold power, it is
vitally important that political satire remains vigorous and unimpeded in a
free society.
For this reason, Franklin and Hugh
Meredith bought the newspaper the Pennsylvania Gazette in 1729. He not only
owned the paper but also wrote satirical pieces in it under aliases.
Join, or Die, the very first
political cartoon in America was personally created by Benjamin in 1754. It
later became an important symbol of colonial unity during the revolution and
remains popular.
7. And finally, his famous Lighting
Rod
Franklin, apart from
being a prolific inventor, is also well known for his scientific
experimentation. Most notably his work on electricity and lightning.
He conducted extensive experiments in the field of
electricity and made some very important discoveries. For example, he was
one of the first people to propose that electricity consisted of two opposing
forces.
He suggested that it
actually moves from one body to another and even coined the terms positive,
negative, battery, charge, and conductor. He is probably best known for his
work with lighting and was adamant that lighting was a form of electricity.
His experiments, including his famous Kite
experiment, enabled him to create a device that would protect buildings from
the destructive force of lightning. Thus, the lightning rod, which protects
structures by earthing, was invented.
