Once a year, every major league baseball player wears the same number. They are united in celebrating one of the most important and influential sports figures of all-time. No one has their names on the back, they all commemorate, in unison, the life and career of Jackie Robinson.
#42 played in his first major league game on this day in 1947 for the Brooklyn Dodgers. This marked the first time a black baseball player participated in a major league baseball game. He broke the color barrier in baseball even before the U.S. Military was desegregated.
