Abner Doubleday, a Union General during the Civil War, is generally credited with inventing the game in 1839, and therefore establishing the first set of rules. (There is substantial evidence that would debunk Doubleday's involvement in the evolution of the game1.) The rules have been revised, improved and clarified many, many times since then.
