Sadly, just three days after turning 99, Hungarian GM Andor Lilienthal passed away. He had not been active as a player for many years (which probably helped maintain his longevity), but he continued to write articles on chess until very recently, possibly right up until his death.
In his career, his "calling card" was his great win over Jose Capablanca from the 1934/35 Hastings tournament, a game which anticipated a similar brilliant win by Mikhail Tal over Hans Joachim Hecht. But he won many other beautiful games, and defeated other champions like Emanuel Lasker, Mikhail Botvinnik and Vassily Smyslov. He tied for first in the one annual super-tournament of the day, the Soviet Championship, back in 1940. So although his salad days are in the distant past (for most of us, anyway), he really was a great player at his best.
Later he worked as a trainer, helping then-future world champion Tigran Petrosian from 1951-1960 and helping Smyslov in his matches against Botvinnik. Later still he emigrated back to Hungary, retired as a player (and trainer) and became a prolific chess columnist. In this lower-stress capacity, he remained active and physically robust until at least very recently. It's not a shock when anyone dies at the age of 99, but it's impressive that there was no sense based on the occasional story about him on ChessBase and elsewhere that his decline was imminent.
