>Lasker was a German chess champion

That doesn't quite do him justice - Emanuel Lasker was world champion for 27 (!) years, 1894-1921, a record not likely ever to be surpassed. And a mathematician (e.g. see https://en.wikipedia.org/wiki/Laskerian_ring ) and fine writer. In fact I learnt to play from Lasker's Manual of Chess. It's very poetic in places, e.g.

On the chessboard, lies and hypocrisy do not survive long. The creative combination lays bare the presumption of a lie; the merciless fact, culminating in the checkmate, contradicts the hypocrite.

edit: I guess you knew that if you were trying chess + clock hehe.
