Westinghouse was the employer of Nikola Tesla and biggest enemy of Edison. Tesla invented alternative current and AC was superior to Edisons DC when the distance travelled on cable. This is the shot from 1908 . Edison invented the electric chair on AC and made propaganda to critic ACs danger. DC is harder to cross from cable to human and Edison killed animals with ac at public meetings.

Tesla is years older when inventing radio and first inventor of inductor motor.
