Ha, yes, I did once know that story about Mozart, due to being a violin nerd who was fed various composer anecdotes once upon a time, also due to violin teacher telling my parents we should watch Amadeus, which I'm glad now that I've watched (multiple times, at this point), but which at the time I was waaaaaay too young for. I'm glad you reminded me of it again, though, as I'd entirely forgotten :D

I feel like I should have known that story about Euler (having also been a math nerd as a child) but I have no memory of it, and my history was sufficiently bad that if someone had told me something like that, I would not have recollected any of the monarchs in question anyway :)

Which is to say, this is all super fascinating :D Oh Fritz. I like that comparison to Elizabeth, it really brings out the visceral OMG NO reaction in me :)
