The German-born American inventor and electrical engineer's theories and mathematical analysis of alternating current systems helped establish them as the preferred form of electrical energy in the U.S. and throughout the world. He advanced research by substituting laboratory methods based on mathematical principles for the older practice of developing a theory and building a model to test it, Cancellation and staple holes (not affecting signature).
