Irving Grant Thalberg (May 30, 1899 - September 14, 1936) was an American film producer during the early years of motion pictures. He was called "The Boy Wonder" for his youth and ability to select scripts, choose actors, gather production staff, and make profitable films, including Grand Hotel, China Seas, Camille, Mutiny on the Bounty, and The Good Earth. His films carved out an international market, "projecting a seductive image of American life brimming with vitality and rooted in democracy and personal freedom," states biographer Roland Flamini.

Cecil B. DeMille was the first who wanted to hire him, telling his partner, Jesse Lasky, "The boy is a genius. I can see it. I know it." Lasky opposed the hire, stating, "Geniuses we have all we need." Thalberg then received an offer from Hal Roach, but the offer was withdrawn because Thalberg lacked experience with slapstick comedy films. In late 1922, Thalberg was introduced to Louis B. Mayer, president of a small, but dynamic and fast-growing studio. At that first meeting, Thalberg "made a deep, immediate impression on Mayer," writes Flamini. After Thalberg had left, Mayer said to studio attorney Edwin Loeb: "Tell him if he comes to work for me, I'll look after him as though he were my son."  Although their personalities were in many ways opposite, Mayer being more outspoken and nearly twice the younger man's age, Thalberg was hired as vice president in charge of production at Louis B. Mayer Productions. Years later, Mayer's daughter, Irene Mayer Selznick, recalled that "it was hard to believe anyone that boyish could be so important." According to Flamini, Thalberg was hired because, although Mayer was an astute businessman, "what he lacked was Thalberg's almost unerring ability to combine quality with commercial success, to bring artistic aspiration in line with the demands of the box office." Mayer's company subsequently merged with two others to become Metro-Goldwyn-Mayer (MGM), with the 24-year-old Thalberg made part-owner and accorded the same position as vice president in charge of production. Three years after the merger, MGM became the most successful studio in Hollywood.  During his twelve years at MGM, Thalberg supervised the production of over four hundred films. Although Thalberg and his colleagues at MGM knew he was "doomed" to not live much past age 30 due to heart disease, he loved producing films. He continued developing innovative ideas and overseeing most of MGM's pictures. Under Thalberg's management, MGM released over 40% more films yearly than Warner Brothers, and more than double Paramount's releases. From 1924 until 1936, when Thalberg died at age 37, "almost every film bore Thalberg's imprint," notes Mark Vieira. Answer this question using a quote from the following article:
