Branch Rickey
Wesley Branch Rickey was an American baseball player, manager, sports executive, and team owner. Rickey was instrumental in breaking the baseball color line by signing black player Jackie Robinson. He also created the framework for the modern minor league farm system, encouraged the major leagues to add new teams through his involvement in the proposed Continental League, introduced the batting helmet, and created the standard 20-80 scouting scale. He was posthumously elected to the Baseball Hall of Fame in 1967.
