April 15th is Jackie Robinson Day in the MLB.

This tradition has been going on since 2004 on the 57th anniversary of Robinson’s debut with the Brooklyn Dodgers. Every year all teams wear 42 on this day and this year the number will be in Dodger blue no matter what team it is. The teams will also have 42 patches on their uniforms and hats.

Jackie Robinson was born in Cairo, Georgia 1919. His mother raised him and his four other siblings by herself. Jackie was great at sports early in life. He went on to attend UCLA where he had varsity letters in four sports: baseball, football, basketball, and track. Robinson enlisted into the Army after financial difficulties at school. In two years Robinson was the second lieutenant but his time was cut short in the Army. He was court-martialed due to objections to incidents of racial discrimination. Jackie ended up leaving the Army with an honorable discharge.

Jackie played one season with the Kansas City Monarchs in 1945 in the Negro Baseball League. The Major Leagues last had an African-American in 1889 that is when the league had gone segregated. When Robinson entered the league in 1947 he had pioneered integration in American athletics. Robinson broke the color barrier in the nation’s top sport at the time challenging segregation in both the north and south.
