most powerful motion-picture executive in Hollywood for 30 years. As the head of Metro-Goldwyn-Mayer (Metro-Goldwyn-Mayer, Inc.), the largest and most prestigious film studio, he created the star system during the 1920s and '30s and had under contract the outstanding screen personalities of the day.

The son of immigrant parents, Mayer worked in his father's ship-salvaging and scrap-iron business from the age of 14. In 1907 he opened his first small nickelodeon in Haverhill, Mass., and by 1918 owned the largest chain of motion-picture theatres in New England. To increase the supply of pictures for his theatres, he opened in Hollywood Louis B. Mayer Pictures and the Metro Pictures Corporation. Six years later MGM was formed by a merger with Goldwyn Pictures Corporation, with Mayer as the controlling head of the new company.

Under Mayer's influence, MGM productions seldom dealt with controversial subject matter. They were characterized, rather, by elaborate sets, gorgeous costuming, and pretty girls. The emphasis was on the glamorous stars, many of whom, such as Greta Garbo, Joan Crawford, Rudolph Valentino, and Clark Gable, were Mayer discoveries. Such pictures as Ben-Hur (1925), Grand Hotel (1932), Dinner at Eight (1933), and The Good Earth (1937) gained MGM the reputation for entertaining films of consistently high quality. Mayer relinquished control of the studio in 1948 and retired completely three years later.
