Arpad Emmerich Elo (né Élő Árpád Imre August 25, 1903 – November 5, 1992) was a Hungarian-American physics professor who created the Elo rating system for two-player games such as chess.
Born in Egyházaskesző, Kingdom of Hungary, he moved to the United States with his parents in 1913. He obtained his BSc and MSc degrees in 1925 and 1928, respectively, both from the University of Chicago, where he also played chess in the Chicago Chess League. Starting from 1926 until his retirement in 1969, he was a physics instructor at Marquette University in Milwaukee. By the 1930s he was the strongest chess player in Milwaukee, at the time one of the nation's leading chess cities. He won the Wisconsin State Championship eight times, and was the 11th person inducted into the World Chess Hall of Fame.
