Jackie Robinson was born in 1919 and was the first African American to play in Major League Baseball, joining the Brooklyn Dodgers in 1947. As he faced racial discrimination and threats, teammates like Pee Wee Reese defended him. Robinson went on to break the color barrier, becoming the first African American player elected to the Baseball Hall of Fame and having his number retired by the Dodgers. He was a champion for civil rights and helped pave the way for integration in professional sports.
