 At that time these would have been Charles F. Peck and Alfred S. Brown, Tesla's financial backers and partners in the Tesla Electric Company.Tesla's story has him convincing these men that a rotating magnetic field AC induction motor would be a feasible invention worth developing via building the "Egg of Columbus" the next day and demonstrating it to them.Reproductions of the device are displayed at the Nikola Tesla Museum in Belgrade, the Memorial Centre "Nikola Tesla" in Smiljan, the Technical Museum in Zagreb, the Croatian History Museum in Zagreb, in the Ann Arbor Hands-On Museum and the Tesla Science Center at Wardenclyffe in Shoreham, NY.
