Throughout the 1880's and 1890's, Tesla (originally working with George Westinghouse) engaged in a fierce battle with Thomas Edison over whether the nascent electrical industry would best be supplied by direct current or alternating current systems. Tesla's alternating current models ultimately won out, due in large part to the vigorous campaigning and public demonstrations by Tesla. "Experiments with Alternate Currents of High Potential and High Frequency," Tesla's most famous lecture, did much to advance his cause and accelerate advancements in the uses of electricity.
