1. Inventions and Theories of 1901-1916 What were they and what did they do for the world?

2. Inventions of 1901-1916 • 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. • 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.

3. Inventions con’t. • 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.

4. Inventions con’t. • 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.

5. Inventions con’t. • 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.

6. Inventions con’t. • The Poulsen Arc Transmitter: Invented in 1902, this device transmitted radio waves to other devices. It was like a huge walkie-talkie. The Pouslen Arc Transmitter helped the U.S. Navy until higher technology, the radio tube systems, came in.

7. Inventions con’t. • The Bra: Invented in 1913 by Mary Phelps Jacob, this was designed because corsets were uncomfortable and had a small selection of sizes. The bra changed women fashion by making it better.

9. 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. Inventions con’t.

15. Inventions con’t. • 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.
