African American baseball legend Jackie Robinson hitting a ball.
Jack Roosevelt Robinson (January 31, 1919 – October 24, 1972) was an American professional baseball player who became the first African American to play in Major League Baseball (MLB) in the modern era. Robinson broke the baseball color line when he started at first base for the Brooklyn Dodgers on April 15, 1947. The Dodgers signing Robinson 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 Fame in 1962.
