Jean Balukas Jean Balukas (born June 28, 1959) is an American pool player from Brooklyn, New York, and ranks among the stellar players in the history of the sport. At least through the 1990s, when Allison Fisher began her ascendancy, Balukas was widely acknowledged as the sole candidate for greatest female player ever. Described as a "trailblazer, a child prodigy, a loner who rebelled against dress codes for women—the pool equivalent of Billie Jean King", she is a five-time Billiards Congress of America (BCA) Player of the Year, was the youngest inductee into the BCA Hall of Fame and the second woman given the honor, and was ranked fifteenth on "Billiard Digest's" Fifty Greatest Players of the [20th] Century.
