Book excerpt: Of baseball there have been countless books, but, surprisingly, relatively few about the owners, the men and women who invested their time--and, frequently, their fortunes--in baseball teams. What has been written tends to concentrate on the financial aspects of ownership or individual owners and their private lives, and pays less attention to the enduring contributions certain owners have made. Eight owners and their lasting influences on the game are the focus of this book. Charles Ebbets, Barney Dreyfuss, Helene Britton, Clark Griffith, Walter O'Malley, Bill Veeck, Charles Finley and August Busch were chosen for inclusion not only because of their larger contributions but also because they were hands-on owners who ran their teams decisively. For instance, Helene Britton proved that a knowledgable woman could successfully run a ball club, even if she couldn't vote; Bill Veeck hired the first black player in the American League, introduced exploding scoreboards and was the first owner to put his players' names on the backs of their uniforms; Walter O'Malley relocated his Dodgers to the West Coast and convinced Giants owner Horace Stoneham to bring his team out too.
