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.
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.

Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.
In the decades after the last voyage, Imperial officials minimized the importance of Zheng He and his expeditions throughout the many regnal and dynastic histories they compiled. The information in the Yongle and Xuande Emperors' official annals was incomplete and even erroneous; other official publications omitted them completely. Although some have seen this as a conspiracy seeking to eliminate memories of the voyages, it is likely that the records were dispersed throughout several departments and the expeditions - unauthorized by (and in fact, counter to) the injunctions of the dynastic founder - presented a kind of embarrassment to the dynasty. State-sponsored Ming naval efforts declined dramatically after Zheng's voyages. Starting in the early 15th century, China experienced increasing pressure from the surviving Yuan Mongols from the north. The relocation of the capital north to Beijing exacerbated this threat dramatically. At considerable expense, China launched annual military expeditions from Beijing to weaken the Mongolians. The expenditures necessary for these land campaigns directly competed with the funds necessary to continue naval expeditions. Further, in 1449, Mongolian cavalry ambushed a land expedition personally led by the Zhengtong Emperor at Tumu Fortress, less than a day's march from the walls of the capital. The Mongolians wiped out the Chinese army and captured the emperor. This battle had two salient effects. First, it demonstrated the clear threat posed by the northern nomads. Second, the Mongols caused a political crisis in China when they released the emperor after his half-brother had already ascended and declared the new Jingtai era. Not until 1457 and the restoration of the former emperor did political stability return. Upon his return to power, China abandoned the strategy of annual land expeditions and instead embarked upon a massive and expensive expansion of the Great Wall of China. In this environment, funding for naval expeditions simply did not happen. However, missions from Southeast Asia continued to arrive for decades. Depending on local conditions, they could reach such frequency that the court found it necessary to restrict them: the History of Ming records imperial edicts forbidding Java, Champa, and Siam from sending their envoys more often than once every three years.
