Reading that bit about him it's a shame I haven't heard of him. He doesn't seem as obscure as some of the people goldendog seems to be able to name.
Alekhine and the cat

Offhand I can't name any tournaments Eliskases won, but I know the roll call of champions he had defeated over the decades.
He's like Lillienthal in that way to me.
Eliskases was a very strong player, Alekhine considered him as a top candidate for the WC.
