Galileo Ferraris (31 October 1847 – 7 February 1897) was an Italian physicist and electrical engineer, one of the pioneers of AC power system and the inventor of induction motor. Many newspapers published that Ferraris's work on the induction motor and power transmission systems was one of the greatest inventions of any age. He published an extensive and complete monograph on the experimental results obtained with open-circuit transformers of the type designed by the power engineers Lucien Gaulard and John Dixon Gibbs.
