Louis Burt Mayer (July 12, 1884 – October 29, 1957) born Lazar Meir (Russian: Лазарь Меир) was an American film producer. He is generally cited as the creator of the "star system" within Metro-Goldwyn-Mayer (MGM) in its golden years. Known always as Louis B. Mayer and often simply as "L.B.", he believed in wholesome entertainment and went to great lengths so that MGM had "more stars than there are in the heavens".
As a studio boss, Louis B. Mayer built MGM into the most financially successful motion picture studio in the world and the only one to pay dividends throughout the Great Depression of the 1930s.
