	Not quite true.  Tesla made polyphase AC PRACTICAL, most particularly
with his invention of induction motors, but there WAS earlier work. 
Somewhere I have a pre-1900 electrical engineering textbook which
mentions some of the earlier work, including two-phase transformer
combinations.  It's buried in about 60 cubic feet of books stored in the
attic of the garage, but if I have the ambition to dig it out I'll share
the reference.
