How did Dizzy Dean get entered into the hall of fame?

Dean, who was inducted into Cooperstown in 1953, attained baseball immortality the old-fashioned way: He earned it. Although his career was short, the colorful pitcher was one of the most dominant players of his time, and he is still the last National Leaguer to win 30 games. If there was a hall of fame for brashness, Dean would have become a member of that one, too, Reportedly, he predicted that he and his brother Paul, also a pitcher with the St. Louis Cardinals, would win 50 games during the 1934 season. Dizzy won 30 and Paul won 19.
