Today's genius is Nicola Tesla. The picture was taken in 1899 in his Colorado Springs research laboratory, where he was looking into some high energy experiments. Tesla was important because his insights, inventions, engineering and mathmatical work is what enabled practical electrical power generation, distribution and use. Being responsible for enabling usable electrical power to be provided to all homes is a pretty big deal. Tesla, while he was a genius, was also a very quirky man. People are still trying to decipher and understand some of his writings and ideas.
