Inventors and Their Inventions:
Have you ever wondered who put the light in lightbulb? Or who put the auto in automobile? Well, today we’re going to learn about that.
Let’s start with an early and well-known inventor. Presenting the guy who made the first moveable type and printing press to go with it — Johann Gutenberg! This happened in 1438. This guy made the first printed Bible. He lived in Germany. Little is known about this person, even his date of birth.
Now, here’s another to add to your collection. This is the guy who put the light in lightning. Introducing — Benjamin Franklin! This guy invented bifocal spectacles. In other words, a new kind of glasses. We know this happened in 1784. How about we learn how these work? When people who wear these look down to read, they see through the near part of the lens, and when they look up, they see the far part of the lens. This is a diagram of bifocal spectacles. 
Here is another inventor that’s pretty popular. Introducing the guy who put the light in light bulb — Thomas Alva Edison! Now the light bulb was the most famous of all his inventions. In fact, he patented, get this, over 1,000 inventions in his life. Some of his other famous inventions are the phonograph and the kinetiscope. 
This is Edison in his lab.
Takeoff! Here’s our final inventor. Or should I say, inventors? 
These two boys made a really successful flight. Introducing — The Wright Brothers! In 1903, the Wright Brothers made their first successful flight in Kittyhawk, North Carolina. Before they made the flight, they were just normal bike mechanics. But if you just believe in yourself, you can do the best things.
The Miles’s Science Encyclopedias were pretty educational. Next time, we’re going to learn about me.
