His teacher thought he was asking so many questions because he was not smart! His mother was so upset at the teacher she pulled him out of school and home-schooled him instead.

At the age of ten he built his first science lab! His mother gave him a book on science and how to do experiments and he fell in love. He kept that love of science for the rest of his life.

After an experiment that went wrong Thomas began to lose his hearing. He was not completely deaf, but he couldn’t hear very well. He said he liked it that way so he could focus on his experiments better!

He was an American inventor, scientist, and businessman who developed many devices that influenced the whole world! Some of his most famous inventions are the phonograph, the motion picture camera, and a long-lasting electric light bulb!

Edison holds 1,093 US patents in his name, that means he invented 1,093 things so nobody has ever invented before!

The American inventor also is famous for his work in telecommunications. He created a machine that could count votes, a battery for an electric car and was able to record music! He is a pretty amazing man!
