Nikola Tesla

Nikola was strange. When he was 7, he started seeing visions. It was part of a mental illness he had for the rest of his life. He was born in Croatia on July 10, 1856. It’s ironic that he was born during a lightning storm, because he would invent things related to electricity. In the 1870's, he went to a college in Graz, Austria. Tesla came to the US in 1884. He worked with Edison for a short time. After that he invented the Tesla coil and AC electric current. Then he went to work with George Westinghouse. Tesla invented lots of things. Tesla invented the Famous Tesla coil, electric oscillators, and the first hydroelectric dam. He also experimented with radios and x-rays and he improved the light bulb. One thing that most people that have heard of Tesla don't know is that he came up with the idea for the smartphone.

In his last years, Tesla worked on inventions. He died in New York on January 7, 1943.
