zanzibar: There was a strong and long running annual memorial tournament in Hungary for this player, the Elekes Memorial GM Tournament.
It was at this tournament in 2002 that Koneru Humpy set the record for youngest female GM, at the age of 15 years, one month and 27 days, breaking Judit Polgar's previous record by three months. (This record has subsequently been broken by ~eight months by Hou Yifan in 2008)
The Elekes Memorial Tournament may still be ongoing, I'm uncertain on that. The most recent reference I can find on the net, with only an admittedly cursory look, is from the 30th Elekes Memorial in 2005.
An short biography of a statistician who is almost certainly the same man can be found in the following link, which includes a photographic portrait:
<<That really a creative man needed at the time, with a systematised mind was chosen is also well shown by the hobby of Dezső Elekes. Namely, the excellent statistician spent his free time on chess.
As an excellent chess player he was a successful member of the Hungarian team that won the world championship in 1952, where he gained 5.5 points in 6 games. The Hungarian Chesslife also commemorated him as one who was "considered a master-level tournament player".
We keep his memories as an excellent statistician and as a statistician playing chess excellently. Therefore the Dezső Elekes chess competition is a large sports event each year, where the elaborate cup has already been merited by many excellent chess players since 1968.>>
PS - Somewhat sadly, on chessgames.com, I don't find any tournament with Elekes name.
E.g. looking for 2002 games with Humpy I do find a tournament named "Budapest FS06 GM 2002". I'm unsure where to find the exact date for a tournament on chessgames, but 365chess gives it as June 1. The Elekes Memorial was in May of that year - so June might match the "hand in" date. I'll leave it there for the moment.
