Tesla gained experience in telephony and electrical engineering before
emigrating to the United States in 1884 to work for Thomas Edison in New
York City. He soon struck out on his own with financial backers,
setting up laboratories and companies to develop a range of electrical
devices. His patented AC induction motor and transformer were licensed
by George Westinghouse, who also hired Tesla for a short time as a
consultant. His work in the formative years of electric power
development was involved in a corporate alternating current/direct
current "War of Currents" as well as various patent battles.
