Bartholomew Faulwell, Ph.D., was a human crewman in Starfleet in the 24th century.
Faulwell was born circa 2320, one of two children of an archeologist father and cultural specialist mother. He was diagnosed as a child with an untreatable kidney defect, which kept him bedridden throughout much of his early years. Despite this, he was able to develop a talent for linguistics, and accompanied his family on research missions. One one such mission, Faulwell misinterpreted the writing within a temple, leading him to declare it safe. It was in fact "a place of punishment," and his sister was killed by the alien mechanism. His sister's kidneys were transplanted to Faulwell, saving his life.
Faulwell enrolled at Starfleet Academy at age eighteen, but dropped out, and pursued his linguistics studies at other institutions, eventually earning his doctorate degree. (SCE eBook: Blackout)
In 2357, after a time as a "stuffy academic," Faulwell joined Starfleet as an enlisted crewman. He was assigned as a linguist aboard the USS Picses during a long-term exploration mission. He served on that vessel for seven years, and finding he enjoyed the work, re-enlisted. (SCE eBook: War Stories)
With the outbreak of the Dominion War, Faulwell's expertise was directed toward decryption of enemy codes. In 2375, he participated in the top-secret Project Mungin (SCE eBook: Echoes of Coventry), and later that year, in another codebreaking effort based on Starbase 92. During that assignment, he met Lieutenant Commander Anthony Mark, with whom he started a romantic relationship. Following the end of the war, Faulwell was assigned to the Starfleet Corps of Engineers team on the USS da Vinci. (SCE eBook: War Stories)
Faulwell and Mark maintained a long-distance relationship for several months, primarily through letters. The relationship became strained, however, after Mark raised the possibility of marriage. (SCE eBook: Creative Coupling)
