Iser Kuperman

Iser Kuperman, sometimes spelled Koeperman, (April 21, 1922 - March 6, 2006) was an originally Ukrainian Jewish player of international draughts. He was born in Habne, today Poliske, Kiev Oblast, on April 21, 1922 and emigrated to Israel and then to the United States in 1978. He was world champion in 1958, 1959, 1961, 1963, 1965, 1967, and 1974. After his emigration, any mention of him was purged from the Soviet records.
After that he became a champion in pool checkers and won in their "Top Master" division from 1984 to 1990. This led him to be referred to as "The Greatest Pool Checkers player of all time" by the Homan Square Pool Checkers & Chess Club of Chicago.
