Jackie Robinson's legacy continues to influence Major League Baseball 75 years after he first broke the league's color barrier with the Brooklyn Dodgers. Robinson was a star from the moment he stepped on the field, excelling despite an environment of hatred and abuse from other players and fans. Baseball retired Robinson's No. 42 leaguewide in 1997, and in 2004 established Jackie Robinson Day, on which the league would honor his memory on the anniversary of his April 15, 1947, debut. Players, managers and umpires all wear No. 42 every April 15, and each team pays tribute to Robinson in its own way.
