Walter O'Malley, the owner of the Brooklyn Dodgers, agrees to move the team from Brooklyn to Los Angeles.

Walter Francis O'Malley was an American sports executive who owned the Brooklyn / Los Angeles Dodgers team in Major League Baseball from 1950 to 1979. In 1958, as owner of the Dodgers, he brought major league baseball to the West Coast, moving the Dodgers from Brooklyn to Los Angeles despite the Dodgers being the second most profitable team in baseball from 1946 to 1956, 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. In 2008, O'Malley was elected to the National Baseball Hall of Fame for his contributions to and influence on the game of baseball.

The Brooklyn Dodgers were a Major League Baseball team founded in 1883 as the Brooklyn Grays. In 1884, it became a member of the American Association as the Brooklyn Atlantics before joining the National League in 1890. They remained in Brooklyn, New York, until 1957, after which the club moved to Los Angeles, California, where it continues its history as the Los Angeles Dodgers. The team moved west at the same time as its longtime rival, the New York Giants, moved to San Francisco in northern California as the San Francisco Giants.

Brooklyn is the most populous of the five boroughs of New York City, coextensive with Kings County, in the U.S. state of New York. Located at the westernmost end of Long Island and formerly an independent city, Brooklyn shares a land border with the borough and county of Queens. It has several bridge and tunnel connections to the borough of Manhattan, across the East River, and is connected to Staten Island by way of the Verrazzano-Narrows Bridge.
