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".
He was born Lazar Meir possibly on July 12, 1884 to a Jewish family in Dymer, Ukraine. His parents were Jacob Meir and Sarah Meltzer and he had two sisters—Yetta, born in 1878, and Ida, born in 1883. Mayer first moved with his family to Rhode Island, where they lived from 1887 to 1892 and where his two brothers were born—Rubin, in April 1888, and Jeremiah, in April 1891. Then, they moved to Saint John, New Brunswick, Canada and Mayer attended school there. He and his brothers often faced anti-Semitic bullies and Mayer was constantly involved in fights. His father started a scrap metal business, J. Mayer & Son. In 1904, the 19-year-old Mayer left Saint John for Boston, where he continued for a time in the scrap metal business, married, and took a variety of odd jobs to support his family when his junk business lagged.
Mayer renovated the Gem Theater, a rundown, 600 seat burlesque house in Haverhill, Massachusetts, which he reopened on November 28, 1907 as the Orpheum, his first movie theater. To overcome the unfavorable reputation that the building once had in the community, Mayer decided to debut with the showing of a religious film. Years later, Mayer would say that the premiere at the Orpheum was From the Manger to the Cross, although most sources place the release date of that film as 1912. Within a few years, he owned all five of Haverhill's theaters, and, with Nathan H. Gordon, created the Gordon-Mayer partnership that controlled the largest theater chain in New England.
