Explanation

Thomas Edison is credited with inventing the electric chair as a method of execution. He developed it in the 1880s as part of the 'War of Currents' to demonstrate that AC electricity (promoted by Tesla/Westinghouse) was more dangerous than DC. The first execution using the electric chair was in 1890 in New York. Edison's involvement is a controversial but historical fact.
