Background: 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.
Context: He found work as an office secretary at Universal Pictures' New York office, and later became personal secretary to the studio's founder and president, Carl Laemmle. Among Thalberg's duties were transcribing and editing notes that Laemmle had written during screenings of his films. He earned $25 weekly, becoming adept at making insightful observations, which impressed Laemmle. Laemmle took Thalberg to see his Los Angeles production facility, where he spent a month watching how movie production worked. Before returning to New York, Laemmle told Thalberg to remain and "keep an eye on things for me." Two months later, Laemmle returned to California, partly to see how well Thalberg was able to handle the responsibilities he was given. Thalberg gave him suggestions, which impressed Laemmle by his ability to understand and explain problems. Thalberg suggested, "The first thing you should do is establish a new job of studio manager and give him the responsibility of watching day-to-day operations." Laemmle immediately agreed, "All right. You're it." In shock, Thalberg replied, "I'm what?" Laemmle told him to take charge of the Los Angeles studio, which he did in early 1919. At age 20, Thalberg became responsible for immediately overseeing the nine ongoing film productions and nearly thirty scenarios then under development. In describing the rationale for this early appointment as studio manager, film historian David Thomson writes that his new job "owed nothing to nepotism, private wealth, or experience in the film industry." He reasons that despite "Thalberg's youth, modest education, and frail appearance . . . it is clear that he had the charm, insight, and ability, or the appearance of it, to captivate the film world." Thalberg was one among the majority of Hollywood film industry workers who migrated from the East Coast, primarily from New York. Some film actors, such as Conrad Nagel, did not like the 5-day train trip or the sudden warmth of the California climate. Neither did Marion Davies, who was not used to such "big wide spaces." Samuel Marx, a close friend of Thalberg's from New York, recalled how easily Thalberg adapted to Southern California, often standing outside his doorway during moments of contemplation to enjoy the scenery. "We were all young," said comedian Buster Keaton. "The air in California was like wine. Our business was also young--and growing like nothing ever seen before."

Background: Dan Gerhard Brown was born on June 22, 1964 in Exeter, New Hampshire. He has a younger sister, Valerie (born 1968) and brother, Gregory (born 1975). Brown attended Exeter's public schools until the ninth grade. He grew up on the campus of Phillips Exeter Academy, where his father, Richard G. Brown, was a teacher of mathematics and wrote textbooks from 1968 until his retirement in 1997.
Context: After graduating from Amherst, Brown dabbled with a musical career, creating effects with a synthesizer, and self-producing a children's cassette entitled SynthAnimals, which included a collection of tracks such as "Happy Frogs" and "Suzuki Elephants"; it sold a few hundred copies. He then formed his own record company called Dalliance, and in 1990 self-published a CD entitled Perspective, targeted to the adult market, which also sold a few hundred copies. In 1991 he moved to Hollywood to pursue a career as singer-songwriter and pianist. To support himself, he taught classes at Beverly Hills Preparatory School. He also joined the National Academy of Songwriters, and participated in many of its events. It was there that he met Blythe Newlon, a woman 12 years his senior, who was the Academy's Director of Artist Development. Though it was not officially part of her job, she took on the seemingly unusual task of helping to promote Brown's projects; she wrote press releases, set up promotional events, and put him in contact with people who could be helpful to his career. She and Brown also developed a personal relationship, though this was not known to all of their associates until 1993, when Brown moved back to New Hampshire, and it was learned that Newlon would accompany him. They married in 1997, at Pea Porridge Pond, near Conway, New Hampshire. In 1994 Brown released a CD titled Angels & Demons. Its artwork was the same ambigram by artist John Langdon which he later used for the novel Angels & Demons. The liner notes also again credited his wife for her involvement, thanking her "for being my tireless cowriter, coproducer, second engineer, significant other, and therapist". The CD included songs such as "Here in These Fields" and the religious ballad, "All I Believe". Brown and his wife, Blythe, moved to his home town in New Hampshire in 1993. Brown became an English teacher at his alma mater Phillips Exeter, and gave Spanish classes to 6th, 7th, and 8th graders at Lincoln Akerman School, a small school for K-8th grade with about 250 students, in Hampton Falls.
