the inventions of Thomas Edison

the invention of lightbolbs i think was the most intersting invention of all time. Thomas Edison developed it and i think that it was really smart of him to. he also invented the Telephone because he was curious for something that he could talk to someone quickly without waiting days for there replay. it was first called the Phonogram but it got changed. He went to the White House to demostrate his inventions. Because back than they used to use Telegrams and they take a long time. Because inventions dealt with a lot of things also improved. Which is why i think that he is one of the most greatest inventor in history.
