Walter Francis O'Malley (October 9, 1903 – August 9, 1979) was an American sports executive who owned the Brooklyn/Los Angeles Dodgers team in Major League Baseball from 1950 to 1979. He served as Brooklyn Dodgers chief legal counsel when Jackie Robinson broke the racial color barrier in 1947. In 1958, as owner of the Dodgers, he brought major league baseball to the West Coast, moving the Dodgers from Brooklyn to Los Angeles and coordinating the move of the New York Giants to San Francisco at a time when there were no teams west of Kansas City, Missouri. For this, he was long vilified by Brooklyn Dodgers fans. However, neutral parties describe him as a visionary for the same business action, and many authorities cite him as one of the most influential sportsmen of the 20th century. His detractors who say that he was not a visionary, but instead a man who was in the right place at the right time, still regard him as the most powerful and influential owner in baseball after moving the team. He was elected to the National Baseball Hall of Fame for his contributions to and influence on the game of baseball.
