Folklore. The basic polyphase and induction motor precepts had previously been set out by Ferraris. Telsa’s own polyphase work (some with Westinghouse) was with two-phase, not three-phase. The original Niagara Falls station generated at two-phase, transmitted at three-phase, using Scott transformers. I think that GE (or one of its predecessors) did the transmission system. For a good early three-phase history, see “Early Three-Phase Power – Winner in the Development of Polyphase AC” by Gerhard Neidhöfer in IEE “Power & Energy Magazine 2007 September-October, p.88ff.
