How did tom Dewey and branh rickey help Jackie of achieving his goal of playing in the major leagues?

Tom Dewey, as a prominent political figure and supporter of civil rights, helped create an environment that was more favorable for Jackie Robinson's entry into Major League Baseball. Branch Rickey, the general manager of the Brooklyn Dodgers, played a crucial role by signing Robinson and providing him with the opportunity to break the color barrier in 1947. Rickey's strategic vision and commitment to integrating Baseball not only gave Robinson a chance to showcase his talent but also offered him the support needed to navigate the challenges of racism in the sport. Together, Dewey and Rickey helped pave the way for Robinson's historic achievement.
