Arpad Elo
Keywords: People
Arpad Emre Elo, born 25 August 1903, developed the Elo Rating System in 1959 at the request of the US Chess Federation. The Elo Rating System was adopted by the
World Chess Federation (FIDE) in 1970. Later (date needed), the USCF modified the Elo rating system to use a slightly different model for the variability in a player's performance substituting one based upon the
logistic distribution in place of Elo's selected
normal distribution.
In 1978, Elo published The Rating of Chessplayers, Past and Present, a book describing his system and presenting ratings for 476 of the world's strongest chessplayers.
