Jack Roosevelt Robinson was an American professional baseball second baseman who became the first African American to play in Major League Baseball in the modern era. Robinson broke the baseball color line when the Brooklyn Dodgers started him at first base on April 15, 1947. When the Dodgers signed Robinson, they heralded the end of racial segregation in professional baseball that had relegated black players to the Negro leagues since the 1880s. Robinson was inducted into the Baseball Hall of F
