6. Abner Doubleday Invented BaseballContrary to popular belief, Abner Doubleday did not invent the game of baseball. In 1907, a committee was formed to document how baseball had originated. The committee concluded that in 1839, as a youngster in Cooperstown, New York, Abner Doubleday drew a diamond-shape diagram for a game he called "Town Ball."
A great story, but merely a myth -- especially considering Doubleday was attending West Point in 1839 and was never known to follow the game he supposedly invented.
Today, it is generally accepted that Alexander Joy Cartwright, a New York bank teller and talented draftsman, invented the game. A plaque in the Baseball Hall of Fame credits him as "the Father of Modern Baseball," while Abner Doubleday has never been enshrined.
