Inventions and
Theories of 1901-1916
What were they and what did they
do for the world?
Inventions of 1901-1916
o The Automobile: Henry Ford
invents the first affordable
automobile. This vehicle was
called the Model-T. At first
this great invention was
outlawed because it scared
the horses on the streets.
Because it was so affordable,
almost anyone could own a
vehicle.
o The Assembly Line: Henry
Ford also created the
assembly line, this made it
possible for him to hire
uneducated workers for jobs.
Because of this, not everyone
had to know all the parts and
how they all fit together.

The First Airplane: On December
17th, 1903, the Wright Brothers
tested and flew the Flyer, a 700
pound aircraft, it was the first
aircraft to have a motor and be
successfully tested. Orville
Wright flew first and his flight
lasted for 12 seconds. Wilber
took his turn a year later and
his flight lasted more than 5
minutes. They called his plane
the Flyer 2.


The “Teddy Bear”: In 1902, the
“Teddy Bear” was invented around
the same time in two parts of the
world, Germany and the U.S.
Supposedly the teddy bear got its
start in the U.S. by a cartoon of
T.R. refusing to shoot a baby bear
while in Mississippi. The demand
was so high that they had to start a
new manufacturer, the Ideal
Novelty and Toy Company. Kids,
both now and then, enjoy the teddy
bears as comfort and consolation.


The “Brownie” Kodak Camera: Invented by
the Eastman Kodak Company in 1900, the
“Brownie” was very low-priced, very simple
to use, and very small. The company
wanted to produce a camera that was
affordable to anyone and simple enough
for everyone. It was just a black
rectangular box in leather. To take a
picture all you had to do was hold at waist
height, aim and turn a switch. Even though
it was so simple to use, an instruction
booklet was included that was 44 pages
long. This camera was only $1.00 each and
film was only 15 cents. To develop, all a
person had to do was send the camera to
the company an they would develop, fill
your camera with film, and send your
camera and your pictures back to you.
With the invention of this simple, hand-held
camera anyone, anywhere, at any time
could take a picture.

• The Poulsen Arc
Transmitter: Invented
in 1902, this device
transmitted radio
waves to other

The First Electric Vacuum
Cleaner: Invented in 1907 by
James Murray Spangler, was a
fan motor attached to a soap
box that was stapled to a broom
handle. Later he improved his
basic design by adding a cloth
filter bag and cleaning
attachments. He started Electric
Sweeper Suction Company in
1908. This all started because he
complained that the carpet
sweeper he used was the cause
of his cough. Now with this
invention, people can reduce
their risk of allergy.

 The Popsicle: First
called the Epsicle, was
invented by an 11 year
old boy named Frank
Epperson in 1905. He
accidentally left his stir
stick in his soda and it
froze. It took him 18
more years to get a
patent. His children
renamed it the Popsicle.
Now everyone can enjoy
the Good ‘N Cool treat

The Push-Pin:
Invented in the early
1900’s by Mr. Edwin
Moore, the first sale
was a package of
push-pins that sold for
$2.00. Today it helps
us to remember
things by letting us
tack notes up on a
wall.


The First Seaplane: Invented on
March 10, 1910. It was an
aircraft designed to take off
and land on water. The first
successful seaplane flight in
America was by Glenn Curtiss
on Jan. 26th, 1911. And on
March 29th, 1919 the U.S.
Navy took the first successful

• Matches: In 1910 the Diamond
Match Company patented the
first non-poisonous match in
the U.S. They used a chemical
called sesquisulfide of
phosphorous. President Taft
asked the company to release
their patent for the good of
mankind. They finally released
it on Jan. 28th, 1911 and this
made it safer for everyone to
use matches because they
didn’t have poisonous
chemicals.

• Cellophane: Cellophane was invented by
Jacques E. Brandenberger in 1908
designed for a clear, protective, packaging
layer. Like many experiments, the original
use was discarded, but he noticed that the
strong thin layers of plastic like material
were good for other uses. In 1917 he
patented this material for use in gas
masks and other various uses.
Theories
• E = mc2: What in the world does it mean
any ways? Well to put it in simple terms it
means that time, and distance are not
absolutes, and that matter can be
converted into energy and that matter and
energy are only different in form.
