Carter, Don (1926-...), an American bowler, was voted the greatest bowler of all time in 1970 in a poll of bowling writers. He was the first to achieve a grand slam--that is, to win the four major bowling titles of his day. These titles were for the World Invitational, All-Star, Professional Bowlers Association (PBA) National, and American Bowling Conference (ABC) Masters championships. Carter helped make bowling a popular television sport in the 1950's.
