WE WILL
NOW COUNT
DOWN OUR
TOP TEN
INVENTIONS!
NUMBER
TEN
Transistor
• We would not have
computers in our houses
without the transistor
because they would be too
BIG!
• Without transistors we
would have to plug in all of
our radios.
• Transistors were invented
in 1947 at Bell Labs.

SEVEN
Printing Press
• The printing press was invented by German
Johannes Gutenberg in the 1440’s.
• It allowed us to print things like books without
having to write it if we wanted a copy.
• Without it, not very many people could go to
school, so a lot of us would not be very
educated as we are now.
• Other people in Europe claimed to have
invented the printing press, but Gutenberg got
the most credit by scholars.

and products get from one
place to another.
• Karl Benz invented the 1st
gasoline powered threewheeled car in 1885 in
Germany. It crashed going two
miles per hour when the driver
lost control and hit a wall.
• Gottlieb Daimler invented a 4wheeled car that same year.

FIVE
Alternating Current
• Nicola Tesla invented
alternating current and then
sold his idea to Westinghouse
in 1885.
• Thomas Edison thought direct
current would be better, but
Tesla’s idea is what we use
today.
• We are glad that Nicola
Tesla invented alternating
current so that we can plug in
to electricity in our houses.

•The wheel was invented about 5000
