Read this paragraph from I Never Had It Made.

Branch Rickey lost that fight, but when he became the boss of the Brooklyn Dodgers in 1943, he felt the time for equality in baseball had come. He knew that achieving it would be terribly difficult. There would be deep resentment, determined opposition, and perhaps even racial violence. He was convinced he was morally right, and he shrewdly sensed that making the game a truly national one would have healthy financial results. He took his case before the startled directors of the club, and using persuasive eloquence, he won the first battle in what would be a long and bitter campaign. He was voted permission to make the Brooklyn club the pioneer in bringing blacks into baseball.
