You know, the first five times I read your comment it didn't make sense. This time I got curious enough to investigate what the hell you're talking about...
Apparently in some countries there is something called "Danish Pastry" or "Danish" for short, I had no idea! Funnily enough, where I grew up, those are called "Wienerbröd" (and in Danish it's "wienerbrød", the same basically) which quite literally translates to "Viennese bread".
So no, I didn't know "Danishes" were Austrian, but I did have the suspicion that Viennese bread was indeed Austrian :)
