For more than a century the owners of baseball franchises conducted their business like feudal barons, with the players in the role of serfs. This situation began to change in 1966, when the Major League Baseball Players Association was formed and Marvin Miller, who had been chief economist and assistant to the president of the steelworkers’ union, became its first executive director. Here he recounts his experience in dealing with club owners and his success in winning a new role for the players. He helped virtually end the system that bound an athlete to one team forever, and thereby raised salaries enormously. Candid in his assessments of the characters involved in this drama, Mr. Miller is nonetheless generous in his comments about the ballplayers who made sacrifices for their union.
