In my spoof article about the most illustrious author Darren Pretzel elsewhere, I mentioned, towards the end, the wrestler-philosopher Georg Hackenschmidt, who was, unlike dear Darren, a real-life figure.
There are various things on the net about this unlikely "a sound mind in a sound body" type of man, including this one:
His fate, being called the Russian Lion demonstrates once again how powerful nations borrow successful people from smaller ones and praise them as their own. Because Hackenschmidt was Estonian, albeit a German-speaking one. He is called George Hackenschmidt in the English-speaking countries, and was, in fact, buried in London.
