Jul 10, 1856

Nikola Tesla was born during a lightning storm in the village of Smiljan, in what is now Croatia. He was the fourth of five children of an Orthodox priest and a talented, inventive mother. A birthmark shaped like a lightning bolt was noted on his chest, which his brother playfully interpreted as an omen of his future connection with electricity.
