Doubleday myth

The Doubleday myth is the claim that the sport of baseball was invented in 1839 by the future American Civil War general Abner Doubleday in Cooperstown, New York. In response to a dispute over whether baseball originated in the United States or was a variation of the British game rounders, the Mills Commission was formed in 1905 to seek out evidence. Mining engineer Abner Graves authored a letter claiming that Doubleday invented baseball. The letter was published in a newspaper and eventually used by the Mills Commission to support its finding that the game was of American origin. In 1908, it named Doubleday the creator of baseball.

The claim initially received a favorable reception from Americans, but eventually garnered criticism from various writers. Modern baseball historians generally consider the myth to be false. Graves' testimony has been critiqued in various regards, as the details of his story and his reliability as a witness have been questioned, and the Mills Commission made departures from his letter in its report. The National Baseball Hall of Fame and Museum was built in the town where Graves said the game was created, Cooperstown. The legend is well known among fans of the sport.
