Following the events of World War 1, Reshevsky immigrated to the United States (1920). As a 9-year old, his first American simultaneous exhibition was with 20 officers and cadets at the Military Academy at West Point. He won 19 games and drew one. He toured the country and played over 1,500 games as a 9-year old in simultaneous exhibitions and only lost 8 games. In his early years he did not go to school and his parents ended up in Manhattan Children's Court on charges of improper guardianship. His benefactor was Julius Rosenwald, founder of Sears & Roebuck. He abandoned chess for 10 years to pursue a vocation as an accountant, receiving an accounting degree from the University of Chicago in 1933. After obtaining his college degree, he devoted himself to tournament chess. Several subsequent successes in international events led to his invitations to both AVRO 1938 and the World Championship Tournament ten years later. Between 1936 and 1942, he had a streak of 75 games without a loss in U.S. Championship competition. He won the US Open in 1944. He played in 21 U.S. Championships, from 1936 to 1981. Over the course of a long international career that continued until he was well over sixty years old, he qualified for the Candidates five times, won the U.S. Championship on six occasions (first time in 1936; last time in 1971)and played a record eleven World Champions ranging from Emanuel Lasker to Anatoli Karpov. He won matches against several notable Western players, including Svetozar Gligoric, Miguel Najdorf and Robert James Fischer (after Fischer was forfeited while the match was tied). However, he was never able to secure the right to a World Championship match. In 1981, at the age of 70, he tied for 3rd place in the U.S. Championship. In 1984, at the age of 72, he took first place in a grandmaster tournament in Reykjavik, Iceland. He was an accountant in New York city,
