Baseball’s lineage stems from Cricket, Stoolball and Rounders. Modern rules develop in Cooperstown, New York with Alexander Cartwright’s book “Baseball.” The first professional team is established before the National League forms amidst a gambling and liquor scandal. Lee Richmond pitches the first ever perfect game. The American League forms, and two years later the winners of each league play in the first World Series. Fans sing “Take Me Out To The Ballgame” during the ‘deadball’ era and Harold Arlin calls the first radio broadcast. The All-American Girls Professional Baseball League forms at the height of World War II. Jackie Robinson becomes the first black professional player. The American League introduces the designated hitter. Players’ strike and for the first time in major league history, the World Series is cancelled. Baseball honors Jackie Robinson by universally retiring number ‘42’ forever.
