Louis Robert Perini (November 29, 1903 in Ashland, Massachusetts – April 16, 1972 in West Palm Beach, Florida) was the principal owner of the Boston Braves/Milwaukee Braves of the National League from 1945 through 1961.
In 1945, he purchased the club from Bob Quinn for $500,000 then moved the club to Milwaukee, Wisconsin for the 1953 season after complaining of poor attendance and revenue in Boston.
At the completion of the 1961 season he sold the franchise for $5.5 million to Chicago insurance executive William Bartholomay who later moved the franchise to Atlanta for the 1966 season, while retaining a 10% interest in the club and sat on the Board of Directors for a number of years.
Prior to owning the Braves, Perini gained his fortune in his family's construction business, Perini Corp, having started out his working life as a water boy in his father's small construction firm, ending up running the major worldwide Perini Corporation.
