Nikola Tesla starts a company, the Tesla…
1887 CE
They set up a laboratory for Tesla at 89 Liberty St. in Manhattan so he can work on his alternating current motor and other devices for power distribution, with an agreement that they share fifty-fifty with Tesla any profits generated from patents.
It is here in 1887 that Tesla constructs a brushless alternating current induction motor based on a rotating magnetic field principle, which he will patent in 1888.
Tesla had considered the winter of 1886/1887 as a time of "terrible headaches and bitter tears".
During this time, he had questioned the value of his education.
