Dignitaries remember Jackie's first game
In 1997, MLB retired his uniform number 42 across all major league teams; he was the first pro athlete in any sport to be so honored. MLB also adopted a new annual tradition, "Jackie Robinson Day", for the first time in 2004, on which every player on every team wears No. 42.
