1916 first constructive use of induction to melt metals
1930’s high frequency motors-generator sets created
1946 Edwin Cady uses basic types of induction equipment
1948- General Electric invests in technology and research
1950s- now- process adapted for production of missiles, beams, die casting , and other uses
