Galileo Ferraris was an Italian university professor, physicist and electrical engineer, one of the pioneers of AC power system and inventor of the induction motor, although he never patented his work. Many newspapers touted that his work on the induction motor and power transmission systems was one of the greatest inventions of all ages. 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.
