1.2 – Nikola Tesla
Nikola Tesla is arguably the poster child of the mad scientist world. He was the closest in real life to the stereotypical mad scientist we see today in everything from kids movies to video games. Nikola was arguably one of the greatest minds of the 20th century doing very early work on X-Rays and radio transmission but later in life his research led him closer to science fiction then real science. With secret blueprints for gigantic death rays in his head, concepts for a projector of human thoughts and plans to wirelessly transmit electricity across the Atlantic. Tesla earned a reputation for being a bit of a kook.
