In 1943, Walter O’Malley (pictured at left) left his law practice to join the Brooklyn Dodgers as vice president and general counsel. He was owner and president of the team by 1950. He brought Major League Baseball to the West Coast when he moved the Dodgers to Los Angeles in 1958. During his tenure, the Dodgers integrated baseball and won 11 pennants and four World Series titles.
