With pride, I can say that I have visited the museum myself in Belgrade. I also attended the elementary school called Nikola Tesla in the near by city called Novi Sad.

And I attended the Nikola Tesla elementary school in a suburb of Belgrade called Rakovica. :)

And I in Zagreb! ;)

Speaking of museums, the Technical Museum in Zagreb, Croatia, has a daily demonstrations of Tesla's most important inventions.

Does that museum offer information in English?

This is what I could find quickly: http://www.mdc.hr/tehnicki/en/07-velikani.htm

That seems very interesting. I need to get myself over there and see it. If you have time would you mind posting about this on the book's home page: http://www.geekatlas.com/forum/topics/i-cant-believe-xyz-isn...

I am embarrassed to say that I haven't yet. I've been back to Belgrade at least twice since I've emigrated to Canada, but I didn't make the time to go.

I'm planning to go back very soon, so that will be a priority.
