I want to know the answer to the following question:
Who built the first induction motor?
All the background I'm provided with is that "In 1824, the French physicist François Arago formulated the existence of rotating magnetic fields, termed Arago's rotations, which, by manually turning switches on and off, Walter Baily demonstrated in 1879 as in effect the first primitive induction motor.". Is that enough to answer the question?
