Who invented the "BAMBI"?

This is the 1 000 000 $ question!!!

Well, imagine that the son of Mr. Simon - whom i interviewed - was involved in the improvements of the "Bambi".

His father, Imre, was a business partner of Mr. Stern at the beginning years of the Szigony business.

Both Mr. Simon and Mr. Stern patented "their" invention.

(That's what i call "politically correct")

Mr. Simon patented in Hungary, of course.

&

Mr. Stern in...

... AUSTRALIA!!!

Mr. Stern trademarked the name "Bambi" in Austria.

I don't know about Mr. Simon.

Fact is that the hungarian machines were also sold with either a "Bambi" badge or an engraved bakelite knob. 

So who invented the "Bambi"?

My heart tells me all 3 of them.
