• What else led to Edison becoming an inventor?
Current Wars• Edison battled for electrical supremacy with a great another
great inventor named Nikola Tesla. Edison invented D.C. Current and Tesla invented A.C. Current. Eventually Tesla’s Alternating Current won out. But, the war between the two was ugly. Find out more about this futile battle.
Edison publically electrocuted an elephant to show that AC current is too dangerous for public use.
The Later Years
• Edison died at in his home in West Orange, NJ on October 13th 1931. As his health declined he was not able to work in his lab as he would have liked. But, he was still had many accomplishments during the latter years of his life. Learn more about those accomplishments here.

Edison had 1,093 patents. Here is a list of his major inventions. Research Edisons other patents. Did he have any failed inventions?
The Light Bulb• Contrary to what you
might have heard, Edison did not invent the light bulb. Edison improved on the light bulb. But, his new design made the light bulb more efficient and practical.
• What improvements did Edison make to the light bulb?
The Phonograph• The phonograph was one of
Edison’s first patented inventions and his favorites. And when you consider the many intricate, working parts it is amazing to think that the idea was soley his own.
• How did he come up with the idea for the phonograph? What would it be used for? Did he need help creating his idea?

Movie Camera• Not only was Edison not the inventor of the first movie
camera. In fact, he refused on offer by Edward Muybridege to create such a contraption.
• Edison’s laboratory was credited for the invention. But, just how involved was Edison?
Kinetoscope • The first movie camera was actually called the Kinetoscope. The film was 18mm wide and ran continuously between two spools. A shutter and aperture were also used to help give the illusion of movement.
• Study the intricate workings of this amazing machine.
DC Current• Despite losing the
“current war” to Nikola Tesla, DC Current is still widely used in electronic equipment everywhere.
• No matter who won the war. This invention brought electricity into the homes of all people.
• What is the difference between AC and DC Current?

Tesla: Master Of Lightning• Nikola Tesla was severely
overshadowed by Thomas Edison during their time. And caused a lot of that by discrediting AC Current. So, unfortunately, Tesla did not make the history books and is not well known by most Americans.
• What other inventions did he create that have impacted society?
